Finance Calculator

A time value of money calculator: solve for FV, PV, payment, rate or periods with payments and compounds per year.

Change the values and press Calculate to work out your own figures.

Solve for FV

Enter N, I/Y, PV and PMT.

About number of periods (n)Payment or compounding periods.
About rate, % a year (i/y)Nominal annual rate; negative allowed.
About present value (pv)A number; negative for money paid out.
About payment (pmt)A number; negative for money paid out.
About contributions at theBeginning earns one more period of interest.
About currencyChanges how amounts are shown, not the math; your choice is remembered on this device.
About payments per year (p/y, optional)1 if blank.
About compounds per year (c/y, optional)Same as P/Y if blank.

P/Y 1, C/Y 1, payments at the end

FV = −$9,455.36.

How to use it

Enter N, I/Y, PV and PMT. Enter N, I/Y, PMT and FV. Enter N, I/Y, PV and FV. Enter N, PV, PMT and FV. Enter I/Y, PV, PMT and FV.

Enter amounts without commas or with them; rates are percentages (5 for 5%). Negative amounts are allowed where a sign means money paid out.

Key facts

PV × (1 + i)^N + PMT × (1 + i × type) × ((1 + i)^N − 1) ÷ i + FV = 0

Signs

Money paid out is negative, money received positive.

Limitations

  • Results are estimates for planning, not offers or financial advice; lenders and banks may round, count days or time payments differently.
  • Rates are nominal annual rates compounded as you choose; payments at a different frequency use the equivalent periodic rate.
