457(b) Deferred Compensation Calculator

How the 457(b) works

A 457(b) is a deferred compensation plan, which means you agree to receive a portion of your salary later rather than now. The deferred amount goes into your account pre-tax, grows without being taxed annually, and comes out as ordinary income when you withdraw.

Two kinds of employers can offer a 457(b). Governmental plans cover state and local government employees: teachers in some states, firefighters, police officers, municipal workers, county employees. Non-governmental plans cover certain tax-exempt organizations, primarily hospitals and large nonprofits, and only a select group of management or highly paid employees. The two types look similar on paper but have very different legal structures, and the differences matter when you leave your job or your employer runs into financial trouble.

Governmental 457(b) assets are held in a trust that's legally separate from your employer. Non-governmental 457(b) assets technically belong to the employer and are only promised to you. That's not a small distinction.

The no-penalty advantage

This is the feature that makes the 457(b) genuinely different from a 401(k) or 403(b). If you withdraw money from a 401(k) before age 59.5, you generally pay income tax plus a 10% penalty, unless you left that employer in or after the year you turned 55 (50 for public-safety employees in a governmental plan). The 457(b) has no such penalty at any age after separation, except on money rolled in from a 401(k) or IRA.

Once you separate from your employer, you can take money out of a governmental 457(b) at any age and owe only ordinary income tax. Retire at 52 after 25 years as a firefighter? You can access your 457(b) the next day. No penalty. Compare that to a 401(k) or 403(b): unless you separated from service in or after the year you turned 55 (50 for public-safety employees in a governmental plan), withdrawals before 59.5 cost an extra $10,000 per $100,000.

Public safety workers (police, firefighters, corrections officers) who retire at 50 benefit most from this. So do early retirees in general, and anyone who wants flexibility to bridge income between retirement and Social Security at 62 or 67. The conventional advice is to spend the 457(b) first and let the IRA compound longer. That's usually right, but your tax situation in retirement should drive the sequencing.

457(b) vs. 403(b): can you have both?

Yes, if your employer offers both. And this is one of the most underused retirement savings opportunities in the public sector.

The 457(b) contribution limit is completely independent of the 403(b) limit. Both sit at $24,500 in 2026. A teacher or hospital employee whose employer offers both can contribute $24,500 to each, for a combined $49,000 in pre-tax deferrals per year. Add catch-up contributions and the number climbs higher.

Most people in this situation only contribute to one. Usually the 403(b), because it's more familiar. The 457(b) sits there, underutilized, and they lose years of tax-deferred compounding on money they could have sheltered. If your employer offers both and you have the income to fund both, fund both.

The 3-year special catch-up provision

In the three calendar years before your plan's normal retirement age, you can contribute up to double the standard limit to a 457(b). In 2026, that means up to $49,000 per year instead of $24,500, for those three years only. The catch: you can only use this provision if you have unused contribution room from prior years when you contributed less than the maximum.

The calculation works like this. Take your normal retirement age defined in the plan. Go back three years from that. Add up the difference between what you could have contributed each year and what you actually contributed. That accumulated room is what you can use to justify contributions above the standard limit during the three-year window.

You can't combine the 3-year special catch-up with the age 50+ catch-up in the same year. You use whichever gives you the higher limit. For most people, if they qualify for the special catch-up with significant unused room, it will allow more than $32,500 (the age 50+ amount), so the special catch-up wins. Your plan administrator has to verify your unused room calculation before you can use it, so don't assume you qualify without confirming.

Non-governmental 457(b): the creditor risk

Hospital employees and large-nonprofit workers often have access to a 457(b) through their employer. The contribution limits and tax treatment look identical to governmental plans. The difference is in the legal structure, and it's significant.

Non-governmental 457(b) assets are held as part of your employer's general assets. You're an unsecured creditor. If your employer files for bankruptcy, your 457(b) balance is at risk alongside other creditors' claims. This has happened. Hospital systems have gone bankrupt with 457(b) balances impaired in the process.

It also can't be rolled to an IRA when you leave, which limits your options. You can take distributions, or roll to another non-governmental 457(b) at a new employer if they have one. For hospital employees evaluating whether to use a 457(b) heavily, this risk profile is worth weighing against the tax deferral benefit. If your employer is financially sound and the plan is well-administered, the risk is low but real.

Withdrawal strategy for early retirees

The 457(b) is the most accessible pre-retirement account you have. No penalty at any age after separation. That makes the withdrawal sequence straightforward for most early retirees: spend the 457(b) first, then taxable brokerage accounts, and let the IRA and 403(b) compound with continued tax deferral.

There's a tax consideration here though. Taking large distributions from a 457(b) in a single year can push you into a higher tax bracket. If you retire at 52 with a $400,000 balance and need $60,000 per year, spreading withdrawals over several years before Social Security kicks in keeps you in a lower bracket than taking a lump sum. You also have the option to do Roth conversions from the IRA in low-income years while the 457(b) covers living expenses.

Required minimum distributions start at 73 (75 if you were born in 1960 or later), or later if you're still working for the plan sponsor, same as other workplace plans. If your 457(b) is large by then, you may be forced to take more than you need. Taking more during early retirement years at favorable tax rates avoids this problem.
