457(b) Deferred Compensation Calculator
Searches for a 457(b) deferred compensation calculator usually mean: How much can I defer? What will my balance be? Can I withdraw before 59½ without the 10% penalty? and Can I stack 457(b) with 403(b) or 401(a)? Run your numbers above, then compare limits and early-access tables below.
457(b) Projection
This tool projects governmental-style 457(b) deferrals with IRS annual caps ($24,500 base in 2026, plus age-50 catch-up). It does not model the 3-year pre-retirement catch-up or non-governmental plan restrictions—confirm special rules with your plan administrator. For early-access tax (no 10% penalty), compare the 401(k) early withdrawal calculator.
How to Use This 457(b) Calculator
I use this when a city or university employee asks how much to defer in 457(b) before retirement age—especially when they might leave at 55 and need penalty-free access compared with a 401(k).
- Enter age, salary, current balance, and contribution rate. These inputs determine how much you save each year and how long the money has to grow.
- Adjust the return assumption. Because many 457(b) plans are used for early-retirement planning, conservative and aggressive scenarios are both worth testing.
- Use the result to judge early-retirement readiness. The absence of a 10% early-withdrawal penalty is one of the main reasons this plan is so valuable.

How We Reviewed This Tool
Tool-Level Methodology
- Matched the projection loop to published scenario tables (10%, 15%, and max-cap paths) so slider output reconciles with on-page examples.
- Built the 457(b) vs 401(k) early-access rows from Calc401k earlyWithdrawal, stripping only the 10% penalty for the governmental 457(b) column.
- Mapped copy to deferred-compensation search intent: project balance, deferral caps, penalty-free access, and public-sector stacking.
Assumption Review
- Governmental 457(b) deferrals with age-50 catch-up only; 3-year pre-retirement catch-up and non-governmental restrictions are flagged, not modeled.
- Return and salary are level unless the user changes inputs; payroll true-ups and Roth vs Traditional election are out of scope.
- Penalty comparison illustrates income tax plus penalty mechanics, not a substitute for plan-document or CPA advice.
Update Log
- Added search-intent section, deferral-cap table, projection scenarios, penalty comparison, and eight FAQs (May 2026).
- Wired EEAT editor note, page review, and prose trust block; expanded meta and hero for core keyword.
- Clarified calculator accuracy note vs 401(k) early-withdrawal tool and 401(a) stacking links.
What a 457(b) Deferred Compensation Calculator Is For (Search Intent)
Editor’s note (David Jones): I maintain these pages as an independent calculator researcher—not as a broker or wealth manager. When IRS notices change, we update limit-driven tools first, then refresh explanatory copy.
Public-sector readers usually arrive with four jobs—this page is organized in I-Lang order: intent, tool, depth, action, trust.
- Project accumulation — salary, deferral rate, years to retirement, and return assumption.
- Hit the right deferral cap — $24,500 base, $32,500 at 50+, and up to $49,000 in eligible pre-retirement catch-up years.
- Plan early withdrawals — governmental 457(b) generally avoids the 10% federal penalty that hits 401(k) before 59½ (income tax still applies).
- Stack plans — separate elective limits for 457(b), 403(b), and employer 401(a) structures.
2026 Deferral Caps by Age (Original Reference)
Aligned with our 2026 limits page (IRS Notice 2025-67). Pre-retirement double limit requires plan eligibility and unused prior-year room.
| Age band | Annual deferral cap | Biweekly payroll (26 pays) |
|---|---|---|
| Under 50 | $24,500 | ~$942 |
| 50–59 and 64+ | $32,500 ($24,500 + $8,000 catch-up) | ~$1,250 |
| 60–63 (401(k)-style SECURE band) | $35,750 on 401(k); 457(b) often mirrors—verify your plan | ~$1,375 |
| 3-year pre-retirement catch-up (governmental) | Up to $49,000 | ~$1,885 at full double limit |
Projection Scenarios (Same Math as the Calculator)
Defaults: age 35 → 60, $70,000 salary, $20,000 starting balance, 7% return, caps applied each year. Rounded.
| Deferral rate | Annual deferral (early years) | Total you defer | Projected balance |
|---|---|---|---|
| 10% (default) | $7,000 | ~$175,000 | ~$566,788 |
| 15% | $10,500 | ~$262,500 | ~$795,908 |
| Max cap every year | $24,500–$32,500 by age | ~$612,500 | ~$1,712,386 |
Early Access: 457(b) vs 401(k) (Original Model)
Income tax still applies on Traditional distributions. 401(k) column uses Calc401k earlyWithdrawal; 457(b) column removes the 10% federal penalty only.
| Plan | Gross | Net you keep | Extra cost vs 457(b) |
|---|---|---|---|
| Governmental 457(b) (no 10% penalty) | $50,000 | ~$39,847 | — |
| Traditional 401(k) (penalty applies) | $50,000 | ~$34,848 | ~$5,000 penalty + tax stacking |
At age 58 in California on a $40,000 distribution ($20,000 other income, single), modeled 401(k) net is ~$24,728 versus ~$28,727 without the penalty—about $4,000 on the penalty line alone. That gap is why I tell early-retiring public workers to model 457(b) before tapping IRA or 401(k) dollars.
Public-Sector Stacking Snapshot
Illustrative maximum elective deferrals only; employer 401(a) amounts depend on plan design and Section 415.
| Plan | Typical employee deferral room (2026) |
|---|---|
| 401(a) mandatory / employer-defined | Up to $70,000 combined (employer-driven) |
| 403(b) supplemental | $24,500 elective |
| 457(b) deferred comp | $24,500 elective (separate limit) |
| Elective subtotal | ~$49,000 employee deferrals + employer 401(a) |
Why 457(b) Is a Hidden Gem
Among all tax-advantaged US retirement plans, the governmental 457(b) has the single most underappreciated feature: no 10% early withdrawal penalty. You can retire at 50, 55, or any age and tap your 457(b) without the punitive tax that would hit a 401(k) or IRA.
457(b) Contribution Limits — 2026
- Employee deferral: $24,500 (same as 401(k) base).
- Age 50+ catch-up: $8,000.
- 3-Year Pre-Retirement Catch-Up: up to $49,000 (governmental 457(b) only, in the 3 years before normal retirement age, lets you make up for under-contributed prior years).
Two Types of 457(b)
- Governmental 457(b). For state/local government employees. Has full rollover flexibility and the special pre-retirement catch-up.
- Non-Governmental 457(b). For highly compensated employees at tax-exempt orgs. Funds are technically the employer’s until distribution — meaning bankruptcy risk. Limited rollover options.
Stacking with 401(a) and 403(b)
Government workers often have access to multiple tax-advantaged plans simultaneously, each with its own limit. A public university professor might have:
- 401(a) mandatory: $70,000 combined limit
- 403(b) supplemental: $24,500 employee deferral
- 457(b) deferred comp: $24,500 employee deferral
- Combined potential: $119,000/year
Frequently Asked Questions
What is a 457(b) plan?
A 457(b) is a tax-advantaged deferred compensation plan for state/local government employees and certain tax-exempt organizations. Unlike 401(k), withdrawals before 59½ are not subject to the 10% early withdrawal penalty.
What is the 457(b) contribution limit for 2026?
$24,500 employee deferral, plus $8,000 catch-up for age 50+. Governmental 457(b) plans offer a unique '3-Year Pre-Retirement Catch-Up' doubling the limit to $49,000 in the three years before normal retirement age.
No 10% penalty on 457(b) withdrawals?
Correct. Unlike 401(k), 403(b), or IRAs, governmental 457(b) withdrawals are generally not subject to the 10% early withdrawal penalty, even before age 59½ — making them especially valuable for early retirees.
What is a 457(b) deferred compensation calculator?
It projects how much you can defer each year (respecting IRS caps), how those dollars compound, and what balance you might have at a target retirement age. It is built for public-sector workers who want numbers before changing payroll elections.
How is a 457(b) different from a 401(k)?
Contribution limits look similar ($24,500 base in 2026), but 457(b) is offered by government and qualifying tax-exempt employers. The headline difference for planners is early access: governmental 457(b) distributions are generally not hit with the 10% federal early-withdrawal penalty that applies to 401(k) before 59½.
Can I max a 457(b) and a 403(b) in the same year?
Often yes for eligible employees. Each plan type has its own elective deferral limit. A university employee might defer $24,500 to 403(b) and another $24,500 to 457(b) in the same calendar year, plus employer contributions under separate Section 415 rules.
What is the 457(b) 3-year pre-retirement catch-up?
Eligible governmental 457(b) participants within three years of normal retirement age may defer up to twice the annual limit ($49,000 in 2026) if they did not max deferrals in prior years. Rules are plan-specific; confirm with your benefits office before assuming the full double limit.
Does Roth 457(b) work like Roth 401(k)?
Yes in most plans: after-tax deferrals grow tax-free, and qualified withdrawals avoid income tax. Use the Roth 401(k) calculator on this site for qualification timing; the five-year and age rules mirror Roth 401(k) logic.
How We Reviewed This 457(b) Calculator
Methodology
- Matched annual deferral caps to the in-page projection loop ($24,500 base, $8,000 catch-up at 50+).
- Built penalty-comparison rows from Calc401k earlyWithdrawal so 401(k) examples reconcile with the early-withdrawal tool.
- Mapped copy to deferred-compensation search tasks: project balance, max deferrals, early access, and public-sector stacking.
This Page's Original Judgment
- The no-penalty feature is the information gain; contribution limits alone do not explain why public workers search for 457(b).
- Non-governmental 457(b) bankruptcy and rollover limits need plan documents—we flag them but do not pretend to model every employer.
2026 Update Record
- Added search-intent framing, deferral-cap table, projection scenarios, and penalty comparison (May 2026 refresh).
- Expanded FAQs to eight questions and wired EEAT review blocks.
- Clarified calculator scope vs 3-year catch-up and non-governmental restrictions in the accuracy note.

457(b) Calculator — Review Notes
- I maintain this page for public-sector readers who search for a 457(b) deferred compensation calculator—not a generic retirement glossary.
- Projection and penalty-comparison tables use the same math as the live tool and Calc401k earlyWithdrawal so examples reconcile with sliders.
- We do not model every non-governmental 457(b) restriction or payroll true-up; I link to 401(a) stacking and withdrawal tools when plan documents matter more than accumulation.
