How to use the business loan calculator

1

Enter the amount the business may need

Use the slider or type directly to set a loan amount between £5,000 and £500,000. The calculator updates immediately so you can see how the amount affects repayments.

2

Select a potential repayment term

Choose from terms between 6 and 60 months. A shorter term means higher regular payments but less total interest, while a longer term spreads the cost.

3

Adjust the example interest rate

Move the slider between 5% and 50% to see how different rates would affect your estimated repayments. This is an illustrative rate you control, not a specific lender offer.

4

Review the estimated repayment and total borrowing cost

The results show your estimated regular payment, total repayment amount, and total interest over the full term. Use these figures as a starting point for planning.

5

Apply for a personalised assessment when ready

When you are ready to explore your actual borrowing options, apply online. A lender will assess your business and provide a tailored quote based on your circumstances.

How business loan repayments are calculated

Business loan repayments are determined by several factors working together. Understanding these can help you make informed borrowing decisions.

Amount borrowed

The total sum you borrow. A larger loan amount means higher regular payments and more total interest over the term.

Repayment term

The length of time over which you repay the loan. Longer terms reduce the regular payment but increase total interest.

Interest rate

The cost of borrowing expressed as a percentage. Higher rates increase both your regular payment and total borrowing cost.

Repayment frequency

How often you make payments. Weekly payments are smaller per payment but more frequent, while monthly payments are larger but less frequent.

Applicable fees

Some loans include arrangement fees, administration charges, or other costs. This calculator shows illustrative interest costs only.

Product structure

Different loan products have different structures. Fixed-rate loans have predictable payments, while other products may vary.

This calculator provides illustrative estimates based on a standard amortising loan formula. It may not include every fee or product-specific cost that could apply to a real business loan.

What affects business loan interest rates?

Business loan interest rates vary between lenders and depend on a range of factors. Understanding what influences rates can help you prepare a stronger application.

Business trading history

Lenders prefer businesses with a proven track record. Longer trading histories may qualify for more favourable rates.

Revenue and cash flow

Consistent monthly revenue and healthy cash flow demonstrate your ability to repay, which can positively influence the rate offered.

Credit profile

Both personal and business credit histories are considered. A strong credit profile may help secure better terms.

Existing financial commitments

Outstanding loans, overdrafts, or other commitments affect affordability and may influence the rate a lender can offer.

Loan amount and term

The amount you borrow and the repayment term can affect the interest rate. Different lenders have different rate structures.

Industry and risk profile

Some industries are considered higher risk than others, which can affect the rates available to your business.

Security or personal guarantee

Unsecured loans may have different rate structures than secured lending. A personal guarantee may be required regardless of the rate.
