What is the Growing Annuity Calculator?
Value a payment stream that grows each period. To use the Growing Annuity Calculator, enter first payment, discount rate, growth, years; it returns present value, final payment, and shows them instantly as you type.
Turning savings into income
Near retirement, the questions change from saving to spending. The annuity payout calculator shows what a lump sum could pay, the Social Security calculator compares claiming ages, and the RMD calculator shows required withdrawals.
How to use the Growing Annuity Calculator
- Enter your numbers. Start with First payment ($), Discount rate (%), Growth (%), then fill in Years. Use today’s balances and your real contribution amounts, then test a more cautious return. Fields marked optional can stay at zero.
- Read the result. The highlighted box gives the Present value, and the cards below show Final payment. Tables and charts break it down further.
- Test other scenarios. Results update as you type. Change one value at a time to see what drives the answer, and press Reset to go back to the defaults.
Formula and how it works
Example with real numbers
Here is the Growing Annuity Calculator using the default values shown in the calculator above:
Inputs
| First payment ($) | 30,000 |
|---|---|
| Discount rate (%) | 6 |
| Growth (%) | 2.5 |
| Years | 25 |
Results
| Present value | $486,885.91 |
|---|---|
| Final payment | $54,261.78 |
With these inputs the calculator returns Present value: $486,885.91. Change any value in the calculator to see how the result moves.
What if you change one input?
Sensitivity check: raising First payment ($) from 30,000 to 36,000 (about 20% higher) and leaving everything else as in the example above changes the results like this:
| Result | Example | After the change | Change |
|---|---|---|---|
| Present value | $486,885.91 | $584,263.09 | +20% |
| Final payment | $54,261.78 | $65,114.13 | +20% |
The input that moves the result most is the one to check twice. Change it in the calculator above to test your own case.
