How the repayment calculator works

This calculator allows you to see what your repayments could be, with a NAB QuickBiz Loan.

Calculator assumptions

Interest rates and repayment cycles

Calculations are based on our headline interest rate (as at the day of your calculation) and are estimates only. When making the calculation, we apply the rate to the full loan term (even where the rate is a variable rate). We do this as we’re unable to predict what rates will do in the future.

We’ve assumed that repayments are payable, and interest is charged, monthly and on the same day. If you have asked us to show you a fortnightly or weekly repayment amount, to keep things simple, we will multiply the monthly repayment amount we have calculated by 12 and then divide it by 26 (for fortnightly repayments) or 52 (for weekly repayments). To calculate monthly interest, this calculator calculates your annual interest charge and divides it by 12 so that interest is spread evenly across each month. Under your contract, the interest calculation takes into account the actual length of each month, so it is slightly different.

Please note: some of the calculations that sit behind the calculator results, we’ve rounded to the nearest dollar.

Time of calculation

We've calculated everything based on the information and figures available as at the date the calculation is made.


We haven’t included any fees or charges that may apply.
