You can still use the full base limit โ the catch-up simply doesn't apply until the year you turn 50.
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.
| Plan | Base Limit | Catch-Up (Age 50+) | Special Catch-Up (Age 60โ63) | 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.
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.
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.
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.
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.
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.
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.
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 60โ63 |
|---|---|---|---|---|
| 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 60โ63 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.
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.
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:
Age 55, 401(k), $10,000 already contributed, 22% bracket, 10 years to retirement, 7% return.
Remaining base = $23,500 โ $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 โ 1) รท 0.07) = $103,623.36
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.
