About this calculator
Calculate the interest and final balance on a term deposit. Banks often pay quarterly, semi-annually or at maturity.
- Interest is taxed at your Resident Withholding Tax rate.
- NZ banks display gross rates. Net rate ≈ gross × (1 − RWT).
Frequently asked questions
Should I pick "compounding" or "interest paid out"?
Compounding earns more if you don't need the income. Paid-out is suitable for retirees needing regular cash.
