How the 403(b) Calculator Works
A 403(b) plan is a tax-advantaged retirement account for employees of schools, nonprofits, and certain religious organizations. This calculator projects your balance at retirement, factoring in rising salary and employer matching.
This 403(b) calculator computes:
- Projected Balance at Retirement — your estimated ending balance
- Total Your Contributions — cumulative employee contributions over time
- Total Employer Match — cumulative employer contributions
- Total Investment Growth — how much your money grew from returns
403(b) Growth Formula
Each year, contributions are calculated as:
Your Contribution = Salary × Contribution % (Salary grows annually by Salary Growth Rate)
Employer Match = Salary × Employer Match %
The combined balance compounds monthly at the expected annual return until retirement.

Frequently Asked Questions
What is a 403(b) plan?
A 403(b) plan is a tax-advantaged retirement savings plan available to employees of public schools, nonprofit organizations, and certain ministers, functioning similarly to a 401(k) offered by for-profit employers.
How is 403(b) growth calculated?
403(b) growth is calculated by compounding your existing balance and ongoing contributions (both yours and your employer’s match) at your expected rate of return over your years until retirement.
Does my employer match count toward my contribution limit?
No. Employer matching contributions do not count against your individual employee elective deferral limit, though they do count toward the overall combined contribution limit for the plan.
What’s the difference between a 403(b) and a 401(k)?
They function very similarly, but 403(b) plans are offered by nonprofit, educational, and religious organizations, while 401(k) plans are offered by for-profit employers. Both offer tax-deferred (or Roth) growth.
