What this calculator does

Term deposits lock money for a fixed tenure at a fixed rate. Interest can be reinvested to compound (cumulative) or paid out monthly or quarterly. This tool handles both, with optional tax withheld.

Formula and method

Cumulative: maturity = P × (1 + r/m)^(m × months/12) Payout: interest per payout = P × r ÷ payouts per year; principal returned at maturity

Worked example

Calculated by this tool with its default inputs:

Inputs

  • Deposit amount: 100000 (any currency)
  • Interest rate (annual): 7 %
  • Tenure: 12 months
  • Compounding: Quarterly
  • Interest payout: Cumulative (reinvested, paid at maturity)
  • Tax withheld on interest: 0 %

Results

  • Maturity value: 107,185.9
  • Total interest (before tax): 7,185.9
  • Tax withheld: 0

How to read the results

Cumulative deposits earn more because interest compounds; payout deposits provide regular income.

Assumptions and limitations

  • Banks may use slightly different day-count and compounding conventions for broken periods.
  • Early withdrawal penalties are not modelled.
