Money maths you can audit. Work out a monthly instalment, see the interest and principal split month by month, add GST, stack two discounts, price a job with markup, or check what compound interest does over ten years. Every figure is computed with a stated formula, and nothing is sent anywhere — which matters when the numbers are your salary or your debt.
Common jobs
- Comparing a ten-year and a fifteen-year loan on total interest
- Adding GST or sales tax to a quote without opening a spreadsheet
- Checking what a 20% plus 10% discount really takes off

Questions
Is this financial advice?
No. These are calculators. They show the arithmetic; decisions about borrowing or investing are yours and, for anything large, a qualified adviser's.
Do the results include fees?
No. Bank fees, insurance and taxes are excluded unless a tool says otherwise, so treat the output as a baseline.
