Tips
Maximize the Employer Match First
Always contribute at least enough to capture 100% of your employer match — it is an immediate 100% return on that portion of your investment.
Account for 2025 Contribution Limits
The 2025 IRS limit for 403(b) employee deferrals is $23,500 ($31,000 if age 50+). Ensure your contribution percentage does not exceed the cap for accurate projections.
Increase Contributions After Raises
Each time you receive a salary increase, raise your contribution percentage by at least 1% so your savings grow alongside your income.
Model Multiple Scenarios
Run the calculator at several return rates (5%, 7%, 9%) to see best-case and worst-case projections rather than relying on a single estimate.
Frequently Asked Questions
What is a 403(b) plan and who is eligible?
A 403(b) plan is a tax-advantaged retirement savings account available to employees of public schools, non-profit organizations, and certain ministers. It works similarly to a 401(k) but is specifically designed for tax-exempt employers.
What is the maximum 403(b) contribution limit for 2025?
For 2025, the IRS allows employees to defer up to $23,500 into a 403(b) plan. Employees aged 50 and older can make an additional catch-up contribution of $7,500, bringing their total to $31,000. Some long-tenured employees may also be eligible for a special $3,000 additional catch-up under the 15-year rule.
How does the employer match work in a 403(b) plan?
When your employer offers a match, they contribute additional money to your 403(b) based on a percentage of your salary. The combined total of employee and employer contributions cannot exceed $70,000 for 2025 (or 100% of compensation, whichever is less).
What is the difference between a 403(b) and a 401(k)?
Both plans offer pre-tax contributions and tax-deferred growth, and they share the same 2025 contribution limit of $23,500. The main difference is eligibility: 403(b) plans are for employees of public schools and tax-exempt organizations, while 401(k) plans are offered by for-profit companies.
