Catch-Up Contribution Calculator

See how much extra you can contribute to your 401(k), IRA, or SIMPLE IRA after age 50 โ€” plus the tax savings and retirement growth your catch-up contributions create.

๐Ÿ’ก 2026 IRS limits are pre-filled below. The base limit, catch-up limit, and special catch-up limit inputs are fully editable โ€” update them yourself if the IRS limits change in future years.

Real-World Catch-Up Contribution Examples

๐Ÿ‘ต Age 55 with a 401(k): The Classic Catch-Up Scenario

You're 55, you contribute to a 401(k), and you've already put in $10,000 this year. You're in the 22% tax bracket with 10 years until retirement and a 7% expected return.

Remaining base: $23,500 โˆ’ $10,000 = $13,500

Catch-up (age 50+): $7,500

Total still available: $21,000

Full annual max with catch-up: $31,000

Tax savings: $7,500 ร— 22% = $1,650/year

Extra retirement income from catch-up: โ‰ˆ $103,623.36

๐ŸŽ‰ Age 62: The SECURE 2.0 Special Catch-Up

You're 62 with a 401(k), haven't contributed yet this year, and are in the 24% bracket with 5 years to retirement and a 7% return.

Special catch-up (age 60โ€“63): $11,250

Remaining base: $23,500 โˆ’ $0 = $23,500

Total still available: $34,750

Full annual max with catch-up: $34,750

Tax savings: $11,250 ร— 24% = $2,700/year

Extra retirement income from catch-up: โ‰ˆ $64,695.81

๐Ÿข Age 52 with a SIMPLE IRA

You're 52 with a SIMPLE IRA, have contributed $8,000, and are in the 22% bracket with 12 years to retirement and a 7% return.

Catch-up (age 50+): $3,500

Remaining base: $16,000 โˆ’ $8,000 = $8,000

Total still available: $11,500

Full annual max with catch-up: $19,500

Tax savings: $3,500 ร— 22% = $770/year

Extra retirement income from catch-up: โ‰ˆ $62,609.58

๐Ÿฉบ Age 58 with an HSA (Family Coverage)

You're 58 with family HSA coverage and have contributed $2,000 this year.

Base limit: $8,550 โ†’ remaining: $6,550

Catch-up (age 55+ for HSAs): $1,000

Total still available: $7,550

Full annual max with catch-up: $9,550

๐Ÿง‘ Age 45: Not Yet Eligible for Catch-Up

You're 45 with a 401(k) and have contributed $5,000 this year.

Catch-up: $0 (age 50 required)

Remaining base: $23,500 โˆ’ $5,000 = $18,500

Total still available: $18,500

You can still use the full base limit โ€” the catch-up simply doesn't apply until the year you turn 50.

How Catch-Up Contributions Are Calculated

Once you turn 50, the IRS lets you contribute more than the normal annual limit to most retirement accounts. The extra amount โ€” the catch-up contribution โ€” sits on top of the base limit, so your true maximum for the year is base limit + catch-up.

Remaining Base = max(Base Limit โˆ’ Already Contributed, 0)
Your unused base-limit room for the year โ€” never goes below $0
Total Still Available = Remaining Base + Catch-Up
Catch-up = $0 under age 50 (HSA: under 55); standard catch-up otherwise; special $11,250 for ages 60โ€“63 in a 401(k)/403(b)/457
FV = C ร— (((1 + r)n โˆ’ 1) / r)
C = annual catch-up, r = annual return (e.g. 0.07 for 7%), n = years until retirement โ€” end-of-year annuity future value
Tax Savings = Catch-Up ร— Tax Bracket
Pre-tax plans only โ€” Roth contributions offer tax-free growth instead of an upfront deduction

2026 Catch-Up Contribution Limits

Plan Base Limit Catch-Up (Age 50+) Special Catch-Up (Age 60โ€“63) Eligibility
401(k) / 403(b) / 457 $23,500 $7,500 $11,250 Age 50+
SIMPLE IRA $16,000 $3,500 โ€” Age 50+
Traditional / Roth IRA $7,000 $1,000 โ€” Age 50+
HSA (self / family) $4,300 / $8,550 $1,000 โ€” Age 55+

These are the 2026 IRS limits used as defaults. Every limit shown in the calculator is an editable input, so you can update the numbers whenever the IRS announces new limits.

How to Estimate Your Catch-Up Room Step by Step

1
Check eligibility โ€” you qualify for catch-up contributions in the year you turn 50 (55 for HSAs). Ages 60โ€“63 in a 401(k)/403(b)/457 qualify for the higher $11,250 special catch-up.
2
Subtract what you've contributed โ€” base limit minus year-to-date contributions gives your remaining base room (floor of $0).
3
Add your catch-up โ€” remaining base plus the applicable catch-up amount is your total still available for the year.
4
Estimate tax savings โ€” multiply the catch-up by your marginal tax bracket for pre-tax plans (e.g. $7,500 ร— 22% = $1,650 saved per year).
5
Project retirement growth โ€” grow the annual catch-up as an end-of-year annuity to retirement using your expected return.

Quick Tips on Catch-Up Contributions

๐ŸŽ‚ Mark Your 50th Birthday

You become eligible for catch-up contributions in the year you turn 50 โ€” you don't have to wait until the actual birthday. For HSAs, the threshold is 55.

๐Ÿ’ฐ Don't Leave Catch-Up Room on the Table

If you can afford it, maxing out the catch-up is one of the highest-leverage moves available โ€” it's more tax-advantaged space on top of your normal limit, every single year.

๐Ÿงพ Know Your Tax Bracket

Pre-tax catch-up contributions reduce your taxable income at your marginal rate. Use your actual marginal bracket โ€” not your effective rate โ€” for an accurate tax-savings estimate.

๐Ÿ“… Check Your Plan's Rules

Employer plans can impose their own limits (e.g. highly-compensated employee rules) and may not offer catch-up provisions. Confirm with your plan administrator before assuming the full IRS room applies.

How Catch-Up Contributions Work After 50

Catch-up contributions are the IRS's way of helping older savers accelerate retirement savings in their final working years. Starting in the year you turn 50, you're allowed to contribute more than the normal annual limit to most retirement accounts. The catch-up sits entirely on top of the base limit โ€” so a 55-year-old in a 401(k) can put away up to $31,000 in 2026 ($23,500 base + $7,500 catch-up), compared with $23,500 for someone under 50.

Who Qualifies

How the Math Works

The calculator first works out your remaining base room: your plan's base limit minus what you've already contributed this year (floored at $0). It then adds the catch-up you qualify for. That sum โ€” remaining base + catch-up โ€” is the total you can still contribute this year. Note that employer matches do not count toward your personal contribution limits, and catch-up contributions are tracked separately by your plan administrator, so there's no risk of accidentally exceeding the base limit.

2026 Catch-Up Contribution Limits at a Glance

The IRS updates retirement contribution limits regularly. Here are the limits in effect for 2026 โ€” the same numbers pre-filled in the calculator above:

Plan Base Limit (2026) Catch-Up Max at Age 50+ Max at Age 60โ€“63
401(k) / 403(b) / 457 $23,500 $7,500 $31,000 $34,750
SIMPLE IRA $16,000 $3,500 $19,500 $19,500
Traditional / Roth IRA $7,000 $1,000 $8,000 $8,000
HSA (self / family) $4,300 / $8,550 $1,000 (age 55+) $5,300 / $9,550 $5,300 / $9,550

The special $11,250 catch-up for ages 60โ€“63 was introduced by the SECURE 2.0 Act and applies only to 401(k)-type plans โ€” not to SIMPLE IRAs, traditional IRAs, or HSAs. The calculator applies it automatically whenever your age is between 60 and 63 and you select a 401(k)/403(b)/457 plan. Remember, IRA catch-up contributions can be made to either a Traditional or Roth IRA, but the $1,000 is shared across all your IRAs in a given year.

Tax Savings and Growth: Why Catch-Up Contributions Matter

Catch-up contributions deliver a rare double benefit: immediate tax savings and decades of compounding. For pre-tax plans, every dollar of catch-up reduces your taxable income this year at your marginal rate. A $7,500 catch-up in the 22% bracket saves $1,650 in federal tax โ€” money that would otherwise go to the IRS.

The Retirement Growth Math

Beyond the tax break, the catch-up itself grows. Modeled as an end-of-year annuity, the future value of contributing your catch-up amount every year until retirement is:

FV = C ร— (((1 + r)n โˆ’ 1) / r)
C = annual catch-up, r = annual return as a decimal, n = years until retirement

๐Ÿ“ˆ The Verified Example

Age 55, 401(k), $10,000 already contributed, 22% bracket, 10 years to retirement, 7% return.

Remaining base = $23,500 โˆ’ $10,000 = $13,500; catch-up = $7,500; total still available = $21,000; full annual max = $31,000.

Tax savings = $7,500 ร— 22% = $1,650/year.

Extra retirement income = $7,500 ร— ((1.0710 โˆ’ 1) รท 0.07) = $103,623.36

Roth vs. Pre-Tax

If your plan (or IRA) is Roth, there's no upfront deduction โ€” contributions are made with after-tax dollars. The trade-off is that qualified withdrawals, including all the growth, are completely tax-free in retirement. For many people in their 50s and 60s who expect to be in a similar or higher bracket later, Roth catch-up contributions can be the better long-term play. Tick the "Roth / after-tax" box in the calculator and the tax-savings card will reflect this.

Frequently Asked Questions

How much can I contribute to my 401(k) after 50?
In 2026, the base 401(k)/403(b)/457 limit is $23,500, and the age-50+ catch-up is $7,500 โ€” so your maximum is $31,000. If you're 60 to 63, the SECURE 2.0 special catch-up raises that to $34,750 ($23,500 + $11,250). These numbers are pre-filled in the calculator and editable if limits change.
What are the catch-up contribution limits for 2026?
For 2026: $7,500 for 401(k)/403(b)/457 plans (or $11,250 for ages 60โ€“63), $3,500 for SIMPLE IRAs, $1,000 for Traditional and Roth IRAs, and $1,000 for HSAs (age 55+). The catch-up is always on top of the base limit, so a 55-year-old with a 401(k) can contribute up to $31,000 total.
When can I start making catch-up contributions?
You're eligible in the year you turn 50 โ€” you don't need to wait for your actual birthday. For HSAs, eligibility starts in the year you turn 55. If you turn 50 in December, you can still use the full catch-up for that entire year, so it often makes sense to front-load contributions early in the year you become eligible.
Do catch-up contributions lower my taxes?
Yes, for pre-tax plans (traditional 401(k), SIMPLE IRA, traditional IRA, HSA). Each dollar of catch-up reduces your taxable income at your marginal rate โ€” e.g. a $7,500 catch-up in the 22% bracket saves about $1,650 in federal tax. For Roth accounts there's no upfront deduction, but qualified withdrawals โ€” including growth โ€” are tax-free in retirement.
What is the special catch-up for ages 60 to 63?
Under the SECURE 2.0 Act, people aged 60โ€“63 in 401(k)/403(b)/457 plans get an elevated catch-up of $11,250 in 2026 โ€” $3,750 more than the standard $7,500. It applies only to 401(k)-type employer plans, not SIMPLE IRAs, traditional IRAs, or HSAs. This calculator applies it automatically when you enter an age in that range with a 401(k)-family plan selected.
Can I make catch-up contributions to an HSA?
Yes. Once you turn 55, you can add a $1,000 HSA catch-up on top of the base limit ($4,300 self-only or $8,550 family in 2026) โ€” for example, a 58-year-old with family coverage can contribute up to $9,550. One catch: you cannot make HSA contributions (including catch-up) after you enroll in Medicare, so plan your final HSA years carefully.
