How This 403(b) Planner Works
A 403(b) plan works a lot like a 401(k)—but it’s designed specifically for employees of public schools, nonprofits, and certain religious organizations. This tool takes your current savings, contributions, employer match, and projected salary growth, then shows you what your retirement picture could look like.
Here’s what you’ll get:
- Your Projected Balance at Retirement — a clear estimate of what you’ll have saved
- Your Total Contributions — everything you’ve put in over the years
- Your Employer’s Total Match — the full value of what your employer contributed
- Total Investment Growth — how much your money earned from compound returns
The Math Behind the Scenes (Kept Simple)
Each year, we calculate contributions like this:
Your Contribution = Your salary × your contribution percentage
(Your salary grows each year based on the salary growth rate you set)
Employer Match = Your salary × employer match percentage
Your total balance compounds monthly at your expected annual return until you retire—giving you a realistic projection of your retirement wealth.

Common Questions About 403(b) Plans
What exactly is a 403(b) plan?
Think of it as the nonprofit version of a 401(k). It’s a tax-advantaged retirement savings plan available to employees of public schools, nonprofits, and certain religious organizations. It works much the same way—you contribute pre-tax (or Roth) dollars, and your money grows tax-deferred.
How is my 403(b) growth calculated?
Your balance grows through a combination of compound returns on your existing savings, plus ongoing contributions from both you and your employer—all multiplied by your expected rate of return over your remaining working years.
Does my employer’s match count toward my contribution limit?
No—your employer’s matching contributions don’t count against your personal elective deferral limit. However, they do count toward the overall combined contribution limit for the plan.
