403(b) Retirement Calculator
Project your 403(b) balance at retirement, including any employer match.
Project your 403(b) balance at retirement, including any employer match.
How 403(b) Retirement Calculator Works
Your contribution is a percentage of salary deducted each pay period, and the employer match is applied up to whatever percentage your employer matches (capped at your own contribution rate if you contribute less than the maximum matched amount). Both amounts are invested monthly and compound at your expected rate of return over the years until retirement — the same mechanics as a 401(k), since 403(b) plans (used by schools, hospitals, and non-profits) work almost identically.
Who Uses 403(b) Retirement Calculator and Why
- Projecting a 403(b) balance at retirement based on a percentage-of-salary contribution rate and years until retirement.
- Estimating how much an employer match adds to total retirement savings over time, on top of personal contributions.
- Testing how increasing your own contribution percentage changes both your own savings and the employer match received, if you're not yet contributing enough to capture the full match.
- Comparing projected growth at different assumed rates of return for a school, hospital, or non-profit retirement plan.
Mistakes to Avoid
- Assuming a stated employer match percentage always applies regardless of your own contribution rate — the calculator caps the match at whatever you personally contribute, since most employer matches only apply up to the percentage you're actually putting in, not as a flat amount.
- Confusing a 403(b) with a 401(k) and assuming the projection mechanics are different — the growth mechanics used here (percentage-of-salary contributions, capped employer match, monthly compounding at an expected return) are effectively the same as a 401(k) projection, since 403(b) plans work almost identically.
- Entering a contribution percentage without checking it against your actual plan's match structure — if your employer match is higher than your own contribution rate, the projected match will be capped at your contribution, understating what you'd get by contributing more.
Tips for Best Results
- If your employer offers a match higher than your current contribution rate, try increasing your contribution percentage input to at least match it — the calculator shows exactly how much additional employer money that unlocks over the projection period.
- Since 403(b) growth mechanics mirror a 401(k), the same general contribution-rate and return-rate sensitivity testing applies — try a couple of different return assumptions to bracket a realistic range for the final projected balance.
Fixing Common Problems
My employer match amount in the projection is lower than the percentage my employer advertises. — Check your own contribution percentage against the employer match percentage — the projected match is capped at whatever you personally contribute, so if your contribution rate is below the maximum matched percentage, you're not yet capturing the full match.
Terms Explained
403(b) plan: A tax-advantaged retirement plan offered by public schools, universities, hospitals, and non-profits, with contribution limits and tax treatment similar to a 401(k).
Employer match: Additional retirement contributions an employer adds based on your own contribution rate, typically capped at your own contribution if it's below the maximum matched percentage.
