Growing Annuity Calculator

Your details

Choose which quantity to calculate. All other fields become your inputs.
Ordinary annuities pay at the END of each period (most loans and savings plans). Annuity due pays at the START and is worth slightly more today.
The payment amount in the very first period.
Total number of payment periods. Use 12 for monthly payments over 1 year, 20 for annual over 20 years.
years
The rate of return used to discount future payments back to today. For present value this is your required return; for future value it is the rate earned.
%
The annual percentage by which each payment grows relative to the previous one. Use 0 for a flat (non-growing) annuity. Can be negative for declining payments.

Lump-sum equivalent of the entire payment stream discounted to today.

Future value$257,946.65
Total cash paid$134,351.87
Interest / growth earned$123,594.78
Last payment$8,767.53
Cash paid$134,351.87
Growth earned$123,594.78

Present value $66,658.32 | Future value $257,946.65

  • Your payment stream grows from its first payment to $8,767.53 in the final period (+3% per year).
  • Total cash paid across all 20 periods is $134,351.87. Compounding and growth lift that to $257,946.65 at the end, a 1.92x multiple.
  • Interest and investment returns add $123,594.78 on top of the cash you put in.
  • Because the discount rate (7%) exceeds the growth rate (3%), the present value is meaningfully less than the sum of nominal payments.

Next stepCompare the present value against a lump-sum alternative. If a vendor offers you a single payment today versus this growing stream, the PV tells you the breakeven point.
