Business Funding Costs: Interest Rates, Fees and Total Cost

The cost of business funding is not determined by the interest rate alone.

Business loans and other forms of debt finance can include arrangement fees, legal costs, valuation fees, broker fees and early repayment charges alongside the interest charged on the money borrowed.

Two funding offers with similar headline business loan interest rates can therefore have very different total costs.

Understanding these charges is essential when comparing business finance.

This guide explains how business finance rates are determined, the difference between fixed and variable rates, the fees you may encounter and how to calculate the real cost of business funding.

What Does Business Funding Cost?

The total cost of business funding can include:

• Interest
• Arrangement fees
• Facility fees
• Legal fees
• Valuation fees
• Broker fees
• Documentation fees
• Early repayment charges
• Other product-specific costs

The exact combination depends on the type of finance.

For example, a straightforward unsecured loan may have relatively few additional costs.

A large secured commercial facility could involve:

• Interest
• Arrangement fee
• Property valuation
• Legal work
• Security documentation

This is why businesses should compare the total amount payable, not simply the advertised interest rate.

What Is a Business Loan Interest Rate?

A business loan interest rate is the charge applied by a lender for providing capital to the business.

It is normally expressed as a percentage.

For example:

Loan: £250,000
Interest rate: 7% per year

The actual amount of interest paid depends on factors including:

• How interest is calculated
• Repayment structure
• Loan term
• Whether the rate is fixed or variable
• How quickly the capital balance reduces

The British Business Bank describes interest as the cost of borrowing and notes that the business loan rate is influenced by factors including the repayment period and collateral offered.

What Business Loan Interest Rate Will I Get?

There is no single business loan interest rate available to every company.

Lenders price finance according to risk.

Factors can include:

• Business credit history
• Director creditworthiness
• Turnover
• Profitability
• Cash flow
• Existing debt
• Trading history
• Loan amount
• Loan term
• Security
• Sector
• Purpose of borrowing
• Wider interest rates

British Business Bank guidance specifically notes that a business with stronger credit or assets available as security may be considered lower risk and could therefore receive more favourable pricing.

Why Do Different Businesses Get Different Finance Rates?

Consider two companies seeking the same £500,000 loan.

Business A

• 10 years of trading history
• £5 million turnover
• £900,000 EBITDA
• Limited existing borrowing
• Commercial property available as security
• Strong credit profile

Business B

• 18 months of trading
• £1 million turnover
• £100,000 EBITDA
• Existing borrowing
• No significant assets
• Weaker credit profile

The lender is likely to view Business B as the higher-risk borrower.

It may therefore receive:

• A higher interest rate
• A lower maximum loan
• A shorter repayment term
• A personal guarantee requirement

or the application may be declined.

Business finance rates reflect the risk of the specific transaction rather than simply the amount being borrowed.

Fixed vs Variable Business Loan Interest Rates

Business finance can be priced using fixed or variable interest rates.

What Is a Fixed Business Loan Rate?

A fixed interest rate remains the same for the agreed fixed-rate period.

For example:

Loan: £300,000
Fixed rate: 7.5%
Term: 5 years

The interest rate itself does not change during the fixed period.

This provides greater certainty when budgeting for repayments.

The British Business Bank describes fixed rates as remaining unchanged through the agreed loan term, helping businesses calculate their interest costs more predictably.

Advantages of fixed rates

• Predictable repayments
• Protection against increases in market rates
• Easier cash-flow planning

Disadvantages

• The business may not benefit if market rates fall
• Early repayment charges may apply
• Fixed pricing may initially be higher than a variable alternative

What Is a Variable Business Loan Rate?

A variable, or floating, interest rate can change during the finance term.

The rate may be linked to a benchmark plus a lender margin.

For example:

Reference rate: 4%
Lender margin: 3%

Total rate: 7%

If the reference rate increases to 5%, the overall rate could become 8%, subject to the lending agreement.

The British Business Bank notes that floating business loan rates can move as lender rates and wider Bank of England rates change.

Advantages of variable rates

• The rate could fall if the benchmark decreases
• Some products may provide greater flexibility

Disadvantages

• Repayments may increase
• Future borrowing costs are less predictable
• Higher rates can put additional pressure on cash flow

What Determines Whether Business Finance Rates Rise or Fall?

Business finance pricing is influenced by both company-specific risk and the wider economic environment.

Factors can include:

• Bank of England Bank Rate
• Cost of funding for lenders
• Competition between providers
• Inflation
• Economic conditions
• Credit risk

However, lenders do not simply charge every company Bank Rate.

They typically add a margin that reflects the risk and structure of the lending.

The British Business Bank's 2025/26 Small Business Finance Markets report notes that SME lending margins vary by product and market segment, and that smaller or higher-risk businesses can pay more than headline averages imply.

What Is APR?

APR stands for Annual Percentage Rate.

It is designed to express the yearly cost of borrowing in percentage terms and can incorporate both interest and certain fees.

The FCA describes APR as an indication of the annual cost of borrowing including interest and fees.

APR can therefore sometimes provide a more useful comparison than the headline interest rate alone.

However, APR should still be considered alongside:

• Total amount repayable
• Loan term
• Monthly repayments
• Fees
• Flexibility

The FCA's 2026 review of APR disclosure found that APR can help consumers compare borrowing products, but that total repayment information can also materially improve understanding of the real cost.

What Is Representative APR?

A representative APR is an advertised rate that, under applicable consumer-credit rules, must be available to at least 51% of customers receiving the relevant credit offer.

It does not mean every applicant will receive that rate.

The actual rate offered can depend on creditworthiness and other factors.

It is also worth remembering that not all forms of commercial lending are regulated in the same way as consumer credit, so APR disclosure requirements vary depending on the product and borrower.

For business funding, always review the actual terms offered to your company.

Interest Rate vs APR vs Total Cost

These three figures tell you different things.

For decision-making, all three can be useful.

However, the total amount payable is particularly important when comparing loans with different:

• Terms
• Fees
• Repayment structures

What Is an Arrangement Fee?

An arrangement fee is a charge made for setting up the finance.

It may be:

• A fixed amount
• A percentage of the loan

For example:

Loan amount: £500,000
Arrangement fee: 2%

Fee:

£500,000 × 2% = £10,000

The fee may:

• Be paid upfront
• Be deducted from the loan proceeds
• Be added to the borrowing

If it is added to the loan, interest may potentially also be charged on that amount depending on the agreement.

Why Arrangement Fees Matter

Suppose two lenders offer:

Lender A

Interest rate: 7%
Arrangement fee: 1%

Lender B

Interest rate: 6.75%
Arrangement fee: 3%

The second lender has the lower headline interest rate.

But that does not automatically make it cheaper.

On a large loan, an additional 2% arrangement fee can be significant.

This is why headline rates should never be compared in isolation.

What Are Facility Fees?

Some finance products charge an ongoing facility fee.

This can be particularly relevant to:

• Revolving credit
• Overdrafts
• Other flexible facilities

A fee may be charged for keeping the facility available even if the business does not use the full amount.

For example:

Credit facility: £500,000
Amount currently drawn: £100,000

The company may pay interest on the £100,000 being used and another fee relating to some or all of the unused facility.

The precise structure depends on the agreement.

What Are Valuation Fees?

Secured business finance may require assets to be valued.

For example:

• Commercial property
• Machinery
• Equipment

A lender considering a property-backed facility may require an independent valuation before agreeing how much it is prepared to advance.

The borrower may be responsible for the valuation cost.

This means secured finance can involve higher upfront transaction costs than a simple unsecured loan even where the ongoing interest rate is lower.

What Legal Fees Can Apply?

Larger or secured facilities can involve legal work.

Possible costs include:

• Lender legal fees
• Borrower legal fees
• Security documentation
• Property-related legal work
• Due diligence

Legal fees are particularly relevant for more complex borrowing, including acquisition finance and property-backed lending.

Ask whether the borrower is responsible for the lender's legal costs as well as its own.

Do Business Finance Brokers Charge Fees?

Sometimes.

How a broker is paid depends on the arrangement.

A broker may:

• Receive commission from the lender
• Charge the borrower
• Receive both lender commission and borrower fees

For example, British Business Bank guidance relating to the Growth Guarantee Scheme states that broker-fee arrangements vary and recommends borrowers understand all potential fees before proceeding.

If you are using a broker, ask:

• How are you paid?
• Is there an upfront fee?
• Is there a success fee?
• Do you receive lender commission?
• Is the fee payable if finance does not complete?

What Is an Early Repayment Charge?

An early repayment charge can apply when a business repays borrowing before the agreed end date.

The lender may charge because it expected to receive interest for a longer period.

The British Business Bank notes that some lenders charge businesses for repaying loans early because the lender has committed capital for the original term.

Before signing an agreement, ask:

• Can I repay early?
• Is there a penalty?
• How is the charge calculated?
• Does the charge reduce over time?
• Can I make partial overpayments?

Flexibility can be particularly valuable where the business expects cash flow to improve.

What Other Business Funding Fees Can Apply?

Depending on the product, additional charges could include:

• Documentation fees
• Due diligence fees
• Monitoring fees
• Administration fees
• Drawdown fees
• Renewal fees
• Exit fees

Specialist products can have their own charging structures.

For example:

Invoice finance may include service fees and discount charges.

Asset finance may include deposits, documentation costs or final purchase fees.

Revolving credit may include commitment or facility charges.

Always request a complete schedule of fees.

How to Calculate the Total Cost of a Business Loan

The simplest principle is:

Total cost of borrowing = total repayments + fees − original amount borrowed

For example:

Suppose:

Business loan: £200,000
Total capital and interest repayments: £245,000
Arrangement fee: £4,000
Legal fees: £2,000

Total cash paid:

£245,000 + £4,000 + £2,000 = £251,000

Total finance cost:

£251,000 − £200,000 = £51,000

This simplified calculation makes it much easier to understand what the finance actually costs.

Example: Comparing Two Business Loans

Suppose your business wants to borrow £500,000.

Offer A

Interest rate: 6.5%
Term: 5 years
Arrangement fee: 2%
Legal and valuation fees: £4,000

Offer B

Interest rate: 6.9%
Term: 5 years
Arrangement fee: 0.5%
Legal and valuation fees: £2,000

At first glance, Offer A has the better interest rate.

But:

Offer A arrangement fee: £10,000

Offer B arrangement fee: £2,500

That £7,500 difference needs to be considered alongside the interest saving.

The correct comparison should therefore include:

• Monthly repayments
• Total interest
• Arrangement fees
• Legal costs
• Valuation fees
• Early repayment flexibility
• Total amount payable

The lowest interest rate is not always the cheapest overall deal.

Why Loan Term Changes the Cost

A longer repayment term can make borrowing easier to afford each month.

However, the business is generally paying interest for longer.

For example, £500,000 borrowed over:

• 3 years
• 5 years
• 7 years

will have very different repayment profiles.

A seven-year facility may offer lower monthly repayments than a three-year facility, but potentially result in more total interest.

Businesses therefore need to balance:

monthly affordability

against:

total borrowing cost

Should You Choose the Shortest Loan Term?

Not automatically.

A shorter term reduces the period over which interest is charged but increases regular repayments.

If the repayments become too aggressive, the business could experience unnecessary cash-flow pressure.

The correct term should reflect:

• Cash generation
• Funding purpose
• Useful life of the investment
• Financial headroom

For example, financing a major piece of machinery over a sensible period linked to its economic life may be more appropriate than forcing repayment over an extremely short term.

How Does Security Affect Business Loan Interest Rates?

Security can reduce lender risk.

A secured lender may have recourse to assets if the borrower defaults.

This can potentially result in:

• Lower rates
• Higher borrowing amounts
• Longer terms

British Business Bank guidance says secured borrowers with appropriate collateral may be considered lower risk and therefore more likely to receive favourable pricing than otherwise similar unsecured borrowers.

However, secured finance can also involve:

• Valuation fees
• Legal fees
• Asset risk

Read Secured vs Unsecured Business Finance: Key Differences for more information.

How Does Credit Affect Business Finance Rates?

Better creditworthiness can help a business obtain more favourable terms.

Lenders may consider:

• Company credit history
• Director credit history
• Previous repayment performance
• County Court Judgments
• Defaults
• Existing borrowing

A weaker credit profile can result in:

• Higher interest
• Additional security
• Personal guarantees
• Smaller funding amounts

or rejection.

How Does Existing Debt Affect Pricing?

Existing borrowing can increase risk.

A heavily indebted company has more existing commitments competing for the same cash flow.

That may affect:

• Whether funding is approved
• Amount offered
• Interest rate
• Security required

This is why lenders consider leverage and repayment capacity when pricing business finance.

How Does the Funding Purpose Affect Cost?

Different funding purposes have different risk profiles.

For example, financing:

• Established machinery
• Commercial property
• Working capital
• A business acquisition
• A speculative new venture

can involve very different lender assessments.

The finance product should also match the purpose.

Using expensive short-term funding for a long-term project may create unnecessary costs.

Cost of Debt vs Cost of Equity

Debt is not the only form of funding with a cost.

Equity funding does not normally involve interest or scheduled capital repayments.

Instead, the company gives investors part ownership.

For example:

A business needs £500,000.

Debt

Borrow £500,000 and pay interest and fees.

Equity

Raise £500,000 and give an investor 20% of the business.

If the company is later sold for £10 million, that 20% could potentially be worth £2 million.

Equity can therefore have a substantial economic cost even though there is no interest rate.

Read Debt Finance vs Equity Finance: Which Is Better for Your Business? for a detailed comparison.

What Is Total Cost of Capital?

More broadly, businesses should think about what all sources of finance cost.

This includes:

Cost of debt

• Interest
• Fees
• Security costs

Cost of equity

• Ownership dilution
• Dividends
• Share of future value

A company using several sources of funding has a combined capital structure.

The objective is not necessarily to find the source with the lowest headline percentage.

It is to create a funding structure that balances:

• Cost
• Risk
• Ownership
• Cash flow
• Flexibility

Business Funding Costs When Buying a Business

Acquisition finance can involve additional costs because transactions are typically more complex.

Potential costs may include:

• Loan interest
• Arrangement fees
• Legal fees
• Due diligence
• Valuations
• Broker or adviser fees

The buyer therefore needs to calculate more than the purchase price.

For example:

Purchase price: £1,500,000
Transaction costs: £100,000
Buyer capital: £300,000

Total capital required before allowing for ongoing working capital may already be:

£1,600,000

This is why acquisition buyers need to consider both deal costs and funding costs when calculating the amount required.

How to Compare Business Finance Offers

Before accepting an offer, compare:

1. Amount provided

Does it meet the actual funding requirement?

2. Interest rate

Is it fixed or variable?

3. Repayment amount

Can the business comfortably afford it?

4. Total interest

How much interest will be paid over the full term?

5. Arrangement fee

How much does it add to the transaction?

6. Other upfront costs

Include legal, valuation and broker fees.

7. Total amount payable

What will the business actually pay in total?

8. Security

What assets are at risk?

9. Personal guarantee

Are directors taking personal exposure?

10. Early repayment

Can you repay early without a significant penalty?

11. Flexibility

Can repayments or drawdowns adapt to the company's requirements?

The best offer is not automatically the one with the lowest interest rate.

Business Finance Comparison Example

Consider these two simplified options:

Loan A has the lower interest rate.

Loan B has:

• Lower upfront fees
• No security
• Greater early repayment flexibility

Which is better depends on the total repayments and what the business values.

For a company intending to repay early, Loan B could potentially be more attractive despite the higher rate.

Questions to Ask a Business Finance Provider

Before accepting finance, ask:

• What is the interest rate?
• Is it fixed or variable?
• What determines changes to the rate?
• What are the monthly repayments?
• What is the total amount repayable?
• What is the arrangement fee?
• Are there legal costs?
• Are there valuation fees?
• Are there broker fees?
• Are there ongoing facility charges?
• Is security required?
• Is a personal guarantee required?
• Are there early repayment charges?
• Can I make additional repayments?
• What happens if I refinance?

Get the answers in writing where appropriate.

How to Reduce Business Funding Costs

Businesses may be able to improve their funding position by:

Improving creditworthiness

Strong credit can reduce lender risk.

Reducing existing debt

Lower leverage can improve affordability.

Providing suitable security

Security may support lower pricing.

Preparing a strong application

Clear financial information makes the risk easier to assess.

Comparing appropriate lenders

Different providers price the same risk differently.

Borrowing only what you need

Unnecessary borrowing creates unnecessary interest.

Choosing an appropriate term

Balance total interest against repayment affordability.

Negotiating fees

For larger facilities, some terms and fees may potentially be negotiable.

Should You Choose the Cheapest Business Finance?

Cost is important, but it is not the only consideration.

The cheapest facility may have:

• Restrictive covenants
• Significant security
• Limited flexibility
• Early repayment penalties

A slightly more expensive facility may give the business considerably more flexibility.

The appropriate decision therefore depends on both:

price

and:

terms

Understanding the Real Cost of Business Funding

Business finance rates are only one part of the total cost of borrowing.

Before accepting funding, consider:

• Interest
• Arrangement fees
• Legal costs
• Valuation fees
• Broker costs
• Ongoing charges
• Early repayment fees

Then compare that cost with:

• The commercial return expected from the investment
• The company's ability to make repayments
• Alternative funding options

Borrowing that costs £50,000 can still be commercially sensible if it enables an investment expected to generate substantially more value.

Equally, a low interest rate does not make borrowing sensible if the business cannot comfortably afford the repayments.

Understand the Full Cost of Buying a Business

When assessing a business acquisition, the purchase price is only part of the total capital you may need.

Funding costs, legal fees, due diligence, valuations and other transaction expenses can all increase the amount required to complete a deal. You also need to leave enough financial headroom for working capital and the day-to-day needs of the business after completion.

At Valius, we help buyers discover established businesses for sale and navigate the wider acquisition journey, including valuation, due diligence, funding and deal structure.

Looking at the full cost of a transaction early can help you compare opportunities more realistically and avoid committing to a deal that leaves too little capital available once the purchase completes.

The cheapest funding option is not always the best one either. The right structure should balance cost, affordability, flexibility and the long-term needs of the business you are acquiring.
