How to use this 457(b) calculator

  1. Enter age and salary

    Set your current age, planned retirement age, and annual salary. This works as a 457(b) calculator by age: changing either age updates how many years you save and compound.

  2. Add contributions and optional match

    Enter your deferral (% of salary or a fixed monthly amount). If your plan offers employer contributions, add match rate and match cap (% of salary). Defaults use 10% deferral and 0% match—typical for many governmental plans.

  3. Set growth assumptions

    Choose expected return, salary growth (default 3%), and plan fees. In Advanced, turn on IRS catch-up, optional special 457 catch-up, or inflation.

  4. 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 for benefits meetings or personal planning.

Frequently asked questions about this 457(b) calculator

How much should I have in my 457(b) when I retire?

There is no one-size-fits-all target—it depends on income, pension, Social Security, and spending goals. This 457 calculator estimates how much your 457(b) could be worth at retirement from your deferrals, optional match, and growth assumptions.

Enter current balance, ages, salary, and deferral rate above. Change current age or retirement age to see how a longer or shorter timeline affects the total. Enable catch-up in Advanced when you are 50+.

How much should I contribute to my 457(b) each month?

There is no single right number—it depends on budget, other savings, and IRS limits. Many public employees start around 5–10% of salary. On $75,000 pay, 10% is about $625/month in deferrals (before taxes).

If your plan offers a match, defer enough to capture it first. Use this tool to see long-term balance impact—not next month’s take-home (see our paycheck calculator).

What percentage of my paycheck should go to a 457(b)?

A common starting range is 5–15% of gross pay, then increase after raises. Maxing the IRS deferral limit ($24,500 base in 2026) on $100,000 salary would require 24.5%—not realistic for everyone.

Use presets on this page or adjust the deferral % until the projected balance meets your goal. Add catch-up in Advanced when you are 50+.

What is the 457(b) contribution limit for 2026?

For 2026, the base employee deferral limit is $24,500 for most workers, plus age 50+ catch-up and SECURE 2.0 enhanced catch-up for ages 60–63 when enabled in Advanced. Combined employee and employer additions follow separate IRS limits (often cited around $72,000—confirm with your plan).

What is the 457(b) catch-up contribution for age 50+?

For governmental 457(b) plans, participants age 50 or older can make an additional $8,000 catch-up deferral in 2026 (on top of the $24,500 base). Ages 60–63 may use an enhanced $11,250 catch-up under SECURE 2.0 when catch-up is enabled.

Turn on catch-up in Advanced so this calculator caps deferrals at the correct annual limit for your age.

What is the 457(b) special catch-up (three-year rule)?

In the last three years before your plan’s normal retirement age, eligible participants may defer up to twice the usual elective deferral limit for that year (still capped by salary). The extra amount above the standard limit counts toward a $15,000 lifetime cap—not everyone qualifies.

In this 457 plan calculator, enable special 457 catch-up in Advanced only if your administrator confirms eligibility, and enter how much of the $15,000 lifetime extra you have already used.

Can I max out both a 401(k) and a 457(b)?

Often yes for elective deferrals: 457(b) limits are generally separate from 401(k) and 403(b) limits, so you may be able to contribute up to the full employee limit in each plan if you are eligible for both.

This calculator models one 457(b) only. Combined annual additions, plan-specific rules, and employer contributions still have caps—confirm with your benefits office before maxing multiple accounts.

How is a 457(b) different from a 401(k)?

401(k) plans are typical at for-profit employers. 457(b) plans are typical for state and local government and some other eligible employers. Dollar limits are similar in 2026, but 457(b) elective deferrals use a separate IRS bucket from 401(k) limits if you participate in both.

Governmental 457(b) plans may allow separation-from-service withdrawals without the usual 10% penalty on qualifying distributions. Model a 401(k) with our 401(k) calculator.

How is a 457(b) different from a 403(b)?

403(b) plans are common at schools, hospitals, and many 501(c)(3) nonprofits. 457(b) plans are common at governmental employers and some other eligible organizations. Both use payroll deferrals and similar dollar limits in 2026, but they are different plan types with separate deferral caps.

403(b) may offer a 15-year service catch-up (not modeled here). Use our 403(b) calculator for nonprofit plan modeling.

Do 457(b) plans have employer matching?

Many governmental 457(b) plans do not offer a traditional employer match—savings come from your deferrals and investment growth. When match exists, it is usually a percentage of what you defer up to a salary cap (example: 50% on the first 6% of pay): match = min(deferral, salary × cap%) × match rate.

Leave match at 0% if your plan has no employer contribution, or use the With match (6%) preset to test a sample formula.

Is there a 10% early withdrawal penalty on a 457(b)?

Governmental 457(b) plans often allow distributions after you separate from service without the 401(k)-style 10% early-withdrawal penalty on qualifying distributions. Ordinary income tax may still apply.

Non-governmental 457(b) rules differ. This calculator does not model withdrawals—confirm access rules with your plan administrator.

How much will my 457(b) be taxed when I withdraw?

Traditional 457(b) deferrals are generally taxed as ordinary income when withdrawn. Roth 457(b) qualified withdrawals may be tax-free on contributions and earnings, depending on plan rules and holding periods.

This tool projects account balance, not tax owed. We do not model federal, state, or local brackets.

Is a 457(b) better than a Roth IRA?

Neither is universally “better.” A 457(b) is a workplace plan with much higher deferral limits and payroll deductions. A Roth IRA is an individual account with its own annual limits and income phase-outs.

Many public employees use both. Compare Roth IRA limits with our Roth IRA calculator, then model your 457(b) balance here.

Traditional vs Roth 457(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 uses the same growth math for either and does not model tax brackets.

See Investor.gov — save for retirement for educational basics.

What is the average 457(b) balance by age?

Published averages vary widely by employer, tenure, and deferral rate—there is no single official number that fits every public employee. Benchmarks from surveys can lag by years and mix governmental and non-governmental plans.

For a personal estimate, use this page: set your age, salary, and deferrals to see a projected balance and yearly chart. Treat industry averages as context only, not a target.

Is a 457(b) a good retirement plan?

For many state and local workers, a governmental 457(b) is a strong way to save: high deferral limits, payroll convenience, and tax-deferred or Roth growth. Quality still depends on fees, investment menu, and how consistently you defer.

It complements—not replaces—emergency savings, pensions, and Social Security. Use this calculator to stress-test your deferral rate; read Investor.gov for general retirement basics.

How much do I need in a 457(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—not a guarantee.

Enter your deferrals above to see whether your projected balance approaches that target.

How does this 457(b) calculator work?

This 457b calculator runs a monthly simulation: salary (with annual growth), your deferral (capped by 2026 IRS limits when catch-up is on), optional employer match, then net return after plan fees. You get balance at retirement, deferral vs. match vs. growth totals, a chart, and a yearly table.

It is not one compound-interest formula—the section How this 457(b) growth calculator works above walks through the same steps in more detail.

Can I download my 457(b) projection?

Yes. Use Export CSV or Export PDF on the results panel to save inputs, assumptions, and the yearly breakdown for your records.

Exports include an educational disclaimer—results are estimates, not tax or investment advice.

Are these 457(b) calculator results guaranteed?

No. Investment returns, fees, job changes, plan rules, and taxes can differ from what you enter. Results are educational estimates for planning—not a promise of future performance, tax outcomes, or account balances.

For decisions about contributions, investments, or withdrawals, use your plan administrator, HR benefits office, or a qualified tax or financial professional.
