Estimate a retirement balance and a planning-level annual withdrawal.
UNDERSTAND THE ANSWER
How is this calculated?
The projection assumes a constant return and regular monthly contributions. It does not model inflation, taxes, fees, market volatility or government benefits.
Retirement accumulation estimateBalance = Current savings growth + Future value of contributions
A practical example
A 35-year-old with $80,000 saved and $800 monthly contributions could build a substantial balance by age 65 at a 6% assumed return.
Assumptions, interpretation and common mistakes
Calculation assumptions
Contributions and returns occur monthly until retirement.
The annual return and withdrawal rate remain constant.
Inflation, taxes, fees, benefits and market sequence risk are excluded.
How to interpret the result
Projected balance is a future-dollar estimate at retirement age.
Estimated growth is not guaranteed and can be negative under adverse returns.
Withdrawal figures are planning references, not a promise that assets will last.
Common mistakes to avoid
Using an aggressive return without testing a lower scenario.
Ignoring inflation when estimating future spending power.
Treating a 4% withdrawal rate as appropriate for every retirement.
