403(b) calculator — balance at retirement
Free 403(b) retirement calculator with employer match for U.S. teachers, nurses, hospital staff, ministers, and other nonprofit employees. Enter your age, salary, deferrals, and plan match to see an estimated balance at retirement, review the yearly chart, and download CSV or PDF. No sign-up required.
What is a 403(b)?
A 403(b) is a U.S. tax-advantaged retirement plan for employees of certain tax-exempt organizations, including many public schools, colleges, hospitals, religious organizations, and other 501(c)(3) employers. You typically save from each paycheck with pre-tax traditional deferrals or Roth 403(b) deferrals when your plan offers them. Plans are often called tax-sheltered annuity (TSA) accounts, but investment menus usually include mutual funds as well.
Eligibility, vesting, investment options, loans, and hardship rules vary by employer. This page helps you model how payroll deferrals, employer match, and assumed growth might add up by a target retirement age. It is educational planning only, not tax, legal, or investment advice.
Work at a for-profit company with a 401(k)? Use our 401(k) calculator instead. You set the return assumption; we do not recommend specific investments or predict markets.
Who can contribute to a 403(b)?
Generally, you can defer into a 403(b) if your employer sponsors a plan and you are an eligible employee of a qualifying organization—commonly:
- Public schools and state colleges or universities
- Hospitals and certain health systems
- 501(c)(3) nonprofits (charities, foundations, and similar tax-exempt employers)
- Ministers employed by religious organizations (rules can differ—confirm with your plan)
Independent contractors, board-only volunteers, and some part-time employees are often not eligible. Your summary plan description (SPD) or HR benefits team can confirm who may enroll and when.
We do not check your eligibility. The calculator models outcomes assuming you can defer and receive match under your plan rules.
Common enrollment questions
New hires may have a waiting period. Some plans exclude employees under a minimum hours threshold. Student employees and adjunct faculty rules vary by institution—your employer’s plan document is definitive.
How to use this 403(b) calculator
Enter age and salary
Set your current age, planned retirement age, and annual salary. This works as a 403(b) calculator by age: changing either age updates how many years you save and compound.
Add contributions and match
Enter your deferral (% of salary or a fixed monthly amount), employer match rate, and match cap (% of salary). Presets model a common full match (often 6% deferral).
Set growth assumptions
Choose expected return, salary growth (default 3%), and plan fees. In Advanced, turn on IRS catch-up, optional 15-year service catch-up, or inflation.
Review balance and export
Read your projected balance, match status, and any deferral-cap notice. Use the chart, yearly table, and CSV or PDF export if you want a copy.
Example with default inputs
With defaults (age 30, retire 65, $75,000 salary, $10,000 starting balance, 6% deferral, 50% match on the first 6% of pay, 6% average return), the projected balance is about $1,208,423. That is illustrative only—not a guarantee.
Raise current age or lower retirement age to see how a shorter timeline changes the total. Turn on catch-up in Advanced at age 50+ to model higher IRS deferral limits.
To compare starting later, keep salary and match fixed and change only ages—the chart shows how much came from your deferrals, employer match, and growth each year.
403(b) calculator with employer match
Employer match is extra money your organization may add when you defer from pay. It is usually a percentage of what you contribute, up to a cap based on your salary. A common formula is 50% of your contributions up to 6% of salary. On $100,000 pay, deferring 6% ($6,000 per year) can add about $3,000 in match; deferring 3% often leaves money on the table.
How to calculate 403(b) match: each month, match = min(your deferral, salary × cap%) × match rate. With 50% on the first 6% of salary, a 6% deferral usually earns the full match.
What counts as a good 403(b) match? Many employers land in the 3–6% of pay range when you defer enough. A 4% match can be strong if you contribute to qualify. Aim for the full match before you chase the IRS deferral maximum.
Use the Full match and Starter presets to compare 6% vs. 3% deferrals. Results show a full, partial, or no match based on your inputs.
Partial match example
On $100,000 salary with 50% match on the first 6%, deferring 3% ($3,000 per year) may yield about $1,500 in employer match—about half the $3,000 available at a 6% deferral. The calculator applies the cap each month so you can spot unused match.
2026 403(b) contribution limits
The IRS sets employee elective deferral limits each calendar year (what you contribute from pay). That is different from employer match or nonelective contributions, and different again from the combined annual additions limit (your deferrals plus all employer contributions, often cited around $72,000 in 2026 for many plans). Confirm current figures with your plan and the IRS.
When catch-up is enabled, this tool caps your deferrals at the IRS limit for your age. Employer match in the simulation does not count toward your elective deferral limit, but real plans must still respect combined caps. We do not trim employer match when a combined total would exceed plan limits.
Turn on catch-up in Advanced for age 50+ limits, including SECURE 2.0 enhanced catch-up for ages 60–63. Long-tenure staff may qualify for an extra $3,000 per year (up to $15,000 lifetime) via the 15-year service catch-up. Enable that toggle only if your plan administrator confirms you are eligible.
| Age (2026) | Employee deferral limit | Total with catch-up (if enabled) |
|---|---|---|
| Under 50 | $24,500 | $24,500 |
| 50–59 | $24,500 | $32,500 (+$8,000 catch-up) |
| 60–63 (SECURE 2.0) | $24,500 | $35,750 (+$11,250 enhanced catch-up) |
| 64 and older | $24,500 | $32,500 (+$8,000 catch-up) |
| 15-year service (if eligible) | +$3,000/year on top of age limit | Up to $15,000 lifetime — Advanced toggle |

How this 403(b) growth calculator works
Instead of a single compound-interest formula, we use a monthly simulation. Each month we adjust salary (with annual growth), add your deferral and employer match, then apply net growth after plan fees.
Employer match (monthly)
match = min(deferral, salary × cap%) × match rateExample on $75,000 salary: 6% deferral ($375/month) with 50% match on the first 6% → up to $187.50/month employer deposit when you capture the full match.
Deferral cap: when year-to-date deferrals reach the IRS limit for your age (including catch-up and optional 15-year service catch-up), employee deferrals stop increasing for that calendar year. You will see a notice if the cap applies.
Salary growth defaults to 3% per year, which raises pay and percent-based deferrals on each anniversary. Optional inflation in Advanced can show an inflation-adjusted balance alongside the nominal total.
Results include balance at retirement, deferral vs. match vs. growth totals, match status, a chart, and an exportable yearly table.

Tips to maximize your 403(b)
1. Get the full employer match first. It is often the strongest guaranteed boost to your savings.
2. Raise deferrals over time. Many people add 1% per year or increase savings after a raise.
3. Watch plan fees. Enter your expense ratio in Advanced; higher fees reduce long-term growth.
4. Use catch-ups when you qualify. At 50+, enable IRS catch-up. Ask HR before you use the 15-year service catch-up toggle.
5. Connect paycheck to retirement. Our paycheck calculator estimates take-home after a deferral; this tool projects balance at retirement.
6. Check purchasing power. Add inflation in Advanced, or explore scenarios with our inflation calculator.
403(b) calculator vs compound interest
This 403(b) growth calculator models payroll deferrals, employer match, and IRS deferral caps—not a single lump-sum compound formula. For “$X per month at Y% for Z years” without a workplace plan, a generic savings calculator is usually simpler.
This 403(b) calculator
Payroll deferrals, employer match with a salary cap, optional 2026 IRS deferral limits (including age catch-up and 15-year service catch-up), salary growth, plan fees, and full/partial match messaging.
Monthly simulation, yearly chart, deferral warnings, breakdown table, CSV/PDF export.
Best for nonprofit and public-sector workers modeling a workplace 403(b).
Compound interest & future value
Flat or recurring contributions without employer match, payroll, or IRS deferral caps.
Good for emergency funds, CDs, or teaching compound growth.
Use our compound interest calculator or future value calculator when 403(b) rules are not needed.
Traditional vs Roth 403(b) (high level)
Many 403(b) plans let you choose traditional or Roth deferrals (or both). The main difference is when you pay income tax, not how investments compound inside the account. This calculator uses the same growth math for either type and does not estimate tax brackets.
Traditional deferrals are usually pre-tax, which lowers taxable wages now. Roth 403(b) deferrals are after-tax today. Your W-2 and pay stub show how your plan reports each election.
Traditional 403(b)
Deferrals are often pre-tax, lowering taxable wages now. Investments grow tax-deferred; withdrawals in retirement are generally taxed as ordinary income.
Often favored if you expect a lower tax rate in retirement than today—this tool does not model brackets.
Roth 403(b) & Roth IRA
Roth 403(b) deferrals are after-tax now; qualified withdrawals may be tax-free later. Roth 403(b) deferrals are not limited by Roth IRA income rules, but not every employer offers Roth.
For Roth IRA contribution limits and MAGI phase-outs, use our Roth IRA calculator. We do not compute Roth vs. traditional tax outcomes here.
403(b) vs 401(k)
401(k) plans are common at for-profit employers. 403(b) plans are common at schools, hospitals, and many nonprofits. Both use payroll deferrals, may include employer match, and follow similar IRS elective deferral limits in 2026.
Some public employers also offer a 457(b) plan—use our 457(b) calculator for that. This page covers 403(b) only, not combined 401(k), 403(b), and 457(b) scenarios. For a corporate 401(k), use our 401(k) calculator.
403(b)
Typical employers: schools, hospitals, religious organizations, and other 501(c)(3) entities.
History of annuity-heavy menus; many plans now offer mutual funds too. May include 15-year service catch-up (Advanced toggle).
Use this calculator for 403(b) match and growth projections.
401(k)
Typical employers: private companies and many corporations.
Often broader investment menus; match and vesting rules vary by plan.
Use our 401(k) calculator if you have a 401(k) instead.
What we do not model
SECURE 2.0 catch-up (ages 60–63)
When catch-up is enabled, ages 60–63 use an enhanced catch-up ($11,250 in 2026 on top of the $24,500 base). Ages 50–59 and 64+ use the standard $8,000 catch-up. The simulation caps employee deferrals accordingly — not employer match or profit-sharing.
15-year service catch-up
Eligible employees with 15 years of service with the same employer may defer an extra $3,000 per year (2026), up to $15,000 lifetime, in addition to normal age-based limits. IRS rules define eligibility—we do not check tenure. Use the Advanced toggle only if you qualify; enter how much you have already used toward the $15,000 lifetime cap.
Combined annual additions (~$72,000)
IRS rules limit total employee deferrals plus employer contributions in a year (often cited around $72,000 for 2026 for many plans). This tool caps your deferrals only; it does not stop employer match when combined totals exceed the plan limit. Confirm with your plan administrator.
Vesting and early withdrawal
Employer match may vest over years; leaving early can forfeit unvested amounts. Early withdrawals before age 59½ often trigger taxes and penalties. This calculator projects balance at retirement — not cash-out or loan scenarios.
403(b) payout in retirement
This tool estimates account balance at retirement, not required minimum distributions (RMDs) or annuity quotes. A common educational shortcut for monthly income is the 4% rule (divide balance by 25 for a rough annual amount). Taxes, Social Security, pensions, and spending needs vary — see the FAQ on $2,000/month planning.
457(b) and bundled public-sector calculators
Some employers sponsor both 403(b) and 457(b) plans. Limits and rules differ; we do not model combined multi-plan optimization here. For 457(b) projections, use our 457(b) calculator.
When to use a simpler calculator
For flat contributions without match or IRS caps, use our compound interest calculator. For take-home pay after a 403(b) deferral, use our paycheck calculator.

Frequently asked questions about this 403(b) calculator
How much will my 403(b) be worth at retirement?
Enter your current balance, ages, salary, deferral rate, employer match, and an assumed return to see an estimated balance at retirement. The 403(b) contribution calculator uses a monthly simulation with optional salary growth and IRS deferral caps when catch-up is enabled.
How much should I contribute to my 403(b) each month?
A practical starting point is enough to get the full employer match—often about 6% of salary when the match is “50% up to 6%.” On $75,000 pay, that is roughly $375/month in deferrals (before taxes).
Increase when you can, up to IRS limits. Use this calculator to see how monthly deferrals plus match affect your balance at retirement—not next month’s take-home (see our paycheck calculator for that).
How does employer 403(b) match work?
Your employer may contribute a percentage of what you defer, up to a cap tied to your salary. Example: 50% match on the first 6% you contribute. This 403(b) employer match calculator applies that cap every month and shows whether you earned a full, partial, or no match.
How do I calculate my 403(b) employer match?
Multiply your deferral (up to the salary cap) by the match rate. Example: $500/month deferred with a 50% match on the first 6% of salary → up to $250/month from your employer if you are under the cap. Enter your plan’s match % and cap % above.
What is a good 403(b) employer match?
Many employers offer match in the 3–6% of salary range when you defer enough to qualify. A common formula is 50% of your contributions up to 6% of pay—on $100,000 salary, deferring 6% can add about $3,000 per year in employer money.
A 4% match can be strong if you contribute to earn it. Aim for the full match before you chase the IRS deferral maximum. Try the Full match preset in the calculator to compare.
How much should I contribute to my 403(b) with an employer match?
Start by deferring enough to get the full employer match—often 6% of salary when the match is “50% up to 6%.” Increase deferrals when your budget allows, up to IRS limits.
How do I max out my 403(b) with an employer match?
Maxing your deferral means hitting the IRS employee limit ($24,500 plus catch-up in 2026, depending on age). Employer match is extra and does not count toward your deferral limit. Enable catch-up in Advanced if you are 50+ to see when the cap applies.
What is the 403(b) contribution limit for 2026?
For 2026, the base employee deferral limit is $24,500 for most workers, plus catch-up for age 50+ and enhanced catch-up for ages 60–63 under SECURE 2.0. Combined employee and employer additions follow separate IRS limits (often cited around $72,000—confirm with your plan).
What is the 403(b) 15-year service catch-up?
If you have 15 years of service with the same eligible employer, you may be able to defer an extra $3,000 per year (2026), up to $15,000 lifetime, on top of the normal elective deferral limit. Not everyone qualifies—see IRS guidance and your plan administrator.
Enable the 15-year service catch-up toggle in Advanced only if you are eligible, and enter how much of the $15,000 lifetime amount you have already used.
Is this a 403(b) calculator by age?
Yes. Set current age and retirement age to define how long you contribute and compound. Results and the yearly chart update when you change either age—helpful for comparing an earlier vs. later start with the same pay and match.
How do I estimate 403(b) payout or monthly income in retirement?
This tool shows projected balance at retirement, not a payout schedule or annuity quote. Many planners use a rough 4% withdrawal rule (educational only): divide balance by 25 for approximate annual income, then by 12 for monthly.
Example: about $4,000/month before taxes from a $1,200,000 balance in that simplified model—real withdrawals depend on RMDs, taxes, and spending. See our annual income calculator for salary or hourly context.
How much will $10,000 in a 403(b) be worth in 20 years?
It depends on return, fees, and ongoing contributions. Illustration only: $10,000 with no further contributions and a steady 7% average return might grow to about $38,700 in 20 years before taxes and inflation—not guaranteed. Add deferrals and match above for a personalized estimate.
How much do I need in a 403(b) to get $2,000 a month in retirement?
Using the educational 4% rule, $2,000/month (about $24,000/year) might call for roughly $600,000 saved, excluding Social Security and pensions. Run your deferrals and match here to see if your projected balance reaches that target.
Does a 403(b) double every seven years?
No—not as a rule. The rule of 72 estimates years to double unchanged principal: divide 72 by your return. At 7%, principal might double in about 10 years—not guaranteed. Ongoing deferrals and match change the path; use the chart on this page or our rule of 72 calculator for a quick doubling estimate.
How is a 403(b) different from a 401(k)?
401(k) plans are common at for-profit employers; 403(b) plans are common at schools, hospitals, and many 501(c)(3) nonprofits. Both use payroll deferrals and similar IRS elective deferral limits in 2026.
403(b) plans may offer a 15-year service catch-up (Advanced toggle here). This page models 403(b) only. For a corporate 401(k), use our 401(k) calculator.
Traditional vs Roth 403(b) — which should I use?
It depends on whether you prefer tax breaks now or later. Traditional deferrals are often pre-tax now and taxable in retirement; Roth deferrals are after-tax now and may be tax-free when qualified. This calculator does not model tax brackets—see Investor.gov — save for retirement for basics.
For Roth IRA limits and MAGI phase-outs, use our Roth IRA calculator.
Who can contribute to a 403(b) plan?
Generally, employees of qualifying tax-exempt employers—such as public schools, many hospitals, 501(c)(3) nonprofits, and some religious organizations—when the employer sponsors a 403(b). Ministers and certain church employees may have special rules.
Contractors, volunteers, and ineligible part-time workers usually cannot defer. Your plan’s eligibility rules are definitive; this tool models savings if you can participate.
Is a 403(b) a good retirement plan?
For many nonprofit and public-sector workers, a 403(b) is a core retirement account: payroll deferrals, tax advantages, and often an employer match. Quality depends on fees, investment options, and whether you capture the full match.
It is not a substitute for emergency savings or a complete financial plan. Use this calculator to stress-test deferrals and match; compare assumptions with Investor.gov basics.
How is this different from a paycheck calculator?
A paycheck calculator estimates take-home pay after taxes and pre-tax 403(b) deductions each pay period. This tool projects 403(b) balance at retirement, not next month’s net pay.
Are these 403(b) calculator results guaranteed?
No. Markets, fees, job changes, plan rules, and taxes can differ from your assumptions. Treat results as educational estimates, not investment advice.
