How are business loan repayments calculated?

Your monthly business loan repayments depend on how much you borrow, the interest rate and the repayment term. Borrowing more or choosing a shorter repayment term will generally increase your monthly repayments, while a lower interest rate can reduce the overall cost of borrowing.

Our business loan calculator estimates your monthly repayments, total interest and total amount repayable based on the figures you enter. It assumes a fixed annual interest rate, equal monthly repayments and no additional fees.

These estimates can help you understand potential borrowing costs and explore different options before applying. Actual rates, fees and repayments will depend on the lender and your circumstances.

The calculator provides an estimate based on your chosen loan amount, repayment term and annual interest rate. It assumes a fixed rate, equal monthly repayments and no additional fees. It is not a loan offer or guarantee of the rate you may receive.

Enter an annual interest rate to see how it affects your repayments. If you haven't received a quote from a lender, try a few different rates to compare potential costs. The rate you are offered may differ depending on your circumstances and the lender's criteria.
