Understanding the Annuity Calculator

Review the inputs, outputs, calculation method, and formulas used by this tool.

Input parameters

Starting Principal
Initial annuity balance.
Annual Addition
Contribution made each year.
Monthly Addition
Contribution made each month.
Add at Each Period's
Whether additions occur at the beginning or end of a period.
Annual Interest
Expected annual annuity growth rate.

Understanding the results

Future value
Projected annuity balance.
Total additions
Initial principal plus recurring contributions.
Interest earned
Growth above contributed amounts.
Schedules
Annual and monthly balance progress.

Calculation principle

An annuity combines compound growth of the starting principal with the future value of regular additions.

  1. Read and validate the entered values.
  2. Convert percentages and time periods into compatible units.
  3. Apply the formulas below and present the calculated results.

Formulas

Ordinary annuity FV = PV(1 + r)^n + PMT × ((1 + r)^n − 1) / r
Annuity due FV_due = FV_ordinary contribution portion × (1 + r)

Symbols refer to the corresponding input and result labels shown above.

How to use this calculator

Enter your figures, choose any available options, and select Calculate. You can change the inputs as often as you like to compare scenarios.
