How this calculator works
The repayment estimate uses the standard amortising-loan payment formula. The monthly payment is based on the amount borrowed, annual interest rate and number of payments. Optional fees are shown separately through the fee inputs.
Important assumptions
Results are estimates. Actual lender calculations can differ because of fee structures, payment timing, interest conventions, product terms and other costs. This calculator is not a loan approval or personalised financial recommendation.
The formula is a mathematical estimate for a standard amortising loan. ToolZeroo does not represent the result as an offer from a lender.
Frequently asked questions
What determines a personal loan repayment?
The loan amount, interest rate, term and any fees entered into the calculator determine the estimate.
Does a longer loan term reduce the repayment?
A longer term can reduce the scheduled periodic payment, but it can increase the total interest paid when the rate remains the same.
Is this a lender quote?
No. It is a mathematical estimate and does not represent an approval, offer or personalised recommendation.
