What is the Savings Plan Calculator?
Project the value of a regular savings plan. To use the Savings Plan Calculator, enter starting balance, monthly saving, annual return, years, yearly increase in saving; it returns final balance, total saved, and shows them instantly as you type.
Where the Savings Plan Calculator fits
Project the value of a regular savings plan. The main figure it returns is the Final balance, worked out from the values you enter.
It belongs with the other budget & planning tools. If you are comparing options or checking a result from another angle, try the 529 Calculator, Cell Phone Plan Calculator or the Long Term Care Calculator.
How to use the Savings Plan Calculator
- Fill in the fields. You will need Starting balance ($), Monthly saving ($), Annual return (%), Years, Yearly increase in saving (%). Start with your real monthly figures, even if they are rounded. Fields marked optional can stay at zero.
- Read the result. The highlighted box gives the Final balance, and the cards below show Total saved. 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 Savings Plan Calculator using the default values shown in the calculator above:
Inputs
| Starting balance ($) | 3,000 |
|---|---|
| Monthly saving ($) | 350 |
| Annual return (%) | 5 |
| Years | 12 |
| Yearly increase in saving (%) | 3 |
Results
| Final balance | $85,491.70 |
|---|---|
| Total saved | $62,606.52 |
With these inputs the calculator returns Final balance: $85,491.70. Change any value in the calculator to see how the result moves.
What if you change one input?
Sensitivity check: raising Starting balance ($) from 3,000 to 3,600 (about 20% higher) and leaving everything else as in the example above changes the results like this:
| Result | Example | After the change | Change |
|---|---|---|---|
| Final balance | $85,491.70 | $86,583.61 | +1.3% |
| Total saved | $62,606.52 | $63,206.52 | +1% |
The input that moves the result most is the one to check twice. Change it in the calculator above to test your own case.
