The question behind Annuity Calculator
This guide helps users understand how regular payments grow when the same amount is contributed or paid at a set frequency. It is most useful for comparing payment size, term, and rate assumptions.
Estimate the future value of regular annuity payments using rate, term, and payment frequency. One useful application is to estimate future value from regular deposits.
Annuity Calculator inputs and assumptions
The Annuity Calculator sample starts with Currency USD, Payment amount 500, Annual rate 5 %, Term 15 years, Payments per year 12. Replace it with values from one Annuity case, then verify Currency and Payments per year against the source information before calculating.
Confusing future value estimates with guaranteed annuity quotes; check that each value belongs to the same Annuity Calculator period, unit, person, account, or scenario.
