How to use this calculator
What this calculator does
Project how current retirement savings and monthly contributions could grow under a stated return assumption.
How to use it
Enter today's invested balance, planned monthly contributions, years until retirement, and an annual return assumption. Re-run the projection with lower returns or different contribution levels to see how sensitive the estimate is.
What the result means
Use the result as a direct calculation from the values you entered. If it looks off, check the inputs and formula shown on this page.

Retirement results are estimates for planning and education. They are not financial advice and do not account for every market, tax, fee, inflation, pension, health, benefit-timing, or personal factor.
Scenario guidance
When to use this
Use this when you want a planning-range estimate of a future retirement balance before comparing contribution, return, or timing scenarios.
Example scenario
A household in mid-career wants to see whether increasing monthly contributions or working a few more years has a larger effect on the projected balance.
Inputs that usually matter most
- Current savings, because that balance compounds across the entire timeline.
- Monthly contribution, which is treated as a regular end-of-month addition.
- Annual return and years to retirement, because small changes to either can materially change a long-term projection.
Common mistake to avoid
Do not read a single return assumption as a forecast. Real returns can arrive unevenly, and inflation, taxes, fees, withdrawals, and contribution changes can shift the result.
How to interpret the result
Compare the projected balance with a separate retirement income or spending target, then test downside cases. A strong-looking nominal balance may still need inflation, tax, and withdrawal analysis.
This calculator is for planning education only. It does not recommend investments, contribution amounts, withdrawal rates, account types, or tax strategies.
Formula
Monthly rate is annual return divided by 12. The calculator compounds current savings and monthly contributions over the entered number of months.
Example retirement projection
$120,000 already saved, $900 contributed monthly, 18 years to retirement, and a 5.5% annual return projects to about $653,121.51. Total contributions are $314,400, with about $338,721.51 from estimated growth.
Frequently Asked Questions
Does this guarantee my retirement balance?
No. It estimates a future balance from the inputs. Actual results depend on market returns, inflation, taxes, fees, and your contribution pattern.
What if I enter a zero annual return?
The calculator treats savings as growing only from current savings plus monthly contributions, without investment growth.
