This calculator computes compounded savings, debt repayments, or annuities. Each of these calculations involves five numbers:

• the initial amount (Present Value, PV),
• the interest rate (percentage added after each period),
• the payment added after each period,
• number of periods (N),
• final value of the investment (Future Value, FV).

You provide four of the numbers, and the calculator computes the other one.

The payment amount is positive for savings accumulation; it’s negative for debt repayment or annuity payments.

The result is copied into “Scratchpad”. All the results have been rounded.
