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.
