When to use this calculator
- Before comparing personal loan or credit offers on the same amount and term.
- When you want to see total interest, not only the monthly payment.
- When you are choosing between a shorter term and a lower monthly debit.
- When you need a planning estimate before making a credit application.
A realistic New Zealand planning example
Use these sample inputs as a quick scenario test, then change one variable at a time to compare outcomes.
| Input | Value |
|---|---|
| Loan Balance (NZ$) | NZ$600,000 |
| Annual Income (NZ$) | NZ$70,000 |
After entering these figures, review annual repayment, weekly repayment and years to pay off together rather than in isolation. Then rerun the tool with one input adjusted.
How to read your results
Annual Repayment
The figure produced by this output for the inputs you entered. Change one variable at a time if you want to see what drives it.
Weekly Repayment
The figure produced by this output for the inputs you entered. Change one variable at a time if you want to see what drives it.
Years to Pay Off
The figure produced by this output for the inputs you entered. Change one variable at a time if you want to see what drives it.
Total Repaid
The headline outcome of this calculation. It is most useful when read alongside the supporting metrics rather than in isolation.
Method & assumptionsAuthoritative sources
This calculator estimates NZ student loan repayments using the 2026/27 IRD compulsory repayment threshold of $24,128 and the 12% repayment rate on income above that threshold. Because NZ-based student loans are completely interest-free, the loan balance divided by the annual compulsory repayment gives a straightforward payoff timeline. The calculator does not model voluntary extra repayments (which would shorten the timeline), income growth over time, or the interest that applies to overseas-based borrowers. For a more detailed projection that includes income growth and overseas interest, see the NZ Student Loan Calculator. This estimator is designed for a quick snapshot of current annual and weekly deductions based on today's income.
Common mistakes
- !Using an assumption that is not supported by a current local quote, bill, statement or official source.
- !Treating a generic estimate as a lender, provider, payroll or tax authority decision.
- !Mixing monthly and annual inputs without converting them consistently.
- !Testing only one scenario instead of checking how a cautious assumption changes the result.
What to do next
- Run a second scenario with a cautious assumption so you can see the downside clearly.
- Compare the result with the related calculators below before making a decision.
- Check current local rules, eligibility and provider terms before applying or committing money.
- Keep a record of the assumptions so you can update the estimate when a quote, bill or pay figure changes.
