Business loan repayment calculator

Work out what a business loan would actually cost before you commit. Enter the amount, rate, term and any arrangement fee to see the monthly repayment, the total interest, and the full cost over the life of the loan.

How it works

The monthly repayment is worked out with the standard amortising-loan formula: each month you pay the same fixed amount, part of which clears interest on the balance still owed and part of which reduces the balance itself. Early payments are mostly interest; later ones are mostly capital. The longer the term, the lower the monthly figure but the more interest you pay overall.

The annual rate is divided by twelve to give a monthly rate, then applied across the number of months in the term. An arrangement fee does not change the monthly repayment shown here; it is a one-off cost added on top, so it is included in the total cost rather than spread across the instalments.

How to use the result

Look at the monthly repayment against your typical monthly cashflow, not just the headline amount you are borrowing. A loan that looks affordable over five years can be a strain in a quiet month. Compare offers on the total cost including the fee rather than the rate alone, since a lower rate with a large arrangement fee can work out dearer than a higher rate with no fee.

This is an estimate for planning only. It is not financial advice and not an offer of credit. Actual repayments depend on the lender's terms and fees and on whether the interest rate is fixed or variable.
