Catch-Up Contribution Calculator

Calculate how much extra you can contribute to your 401(k) and IRA using catch-up provisions once you reach age 50, and see the long-term impact on your retirement balance.

Frequently Asked Questions

What is the 401(k) catch-up limit for ages 60-63 in 2026?

The SECURE 2.0 super catch-up for ages 60-63 allows an additional $11,250 above the $23,500 base, for a total of $34,750 - the highest available 401(k) contribution window.

Is the catch-up contribution mandatory once I turn 50?

No. Catch-up provisions are optional. You can contribute any amount between zero and the full limit. Simply update your payroll deferral to use it.

Does the employer match apply to catch-up contributions?

It depends on the plan. Most employer match formulas are based on a percentage of salary up to a cap, which is usually met by the regular deferral. Catch-up dollars may or may not receive a match - review your plan document.

Can I make catch-up contributions to both a 401(k) and an IRA?

Yes. The 401(k) catch-up and the IRA catch-up are separate limits. In 2026, eligible savers can contribute up to $34,750 to a 401(k) (ages 60-63) and $8,000 to an IRA (age 50+) simultaneously, subject to income rules.

How This Calculator Works

This calculator computes the catch-up contribution limits that apply to your age under 2026 IRS rules and then projects the cumulative impact of using those extra contributions through a target retirement age. It applies compound growth to the additional amounts at your assumed annual return, giving you a side-by-side comparison of a retirement balance with and without the catch-up.

The projection uses a standard future-value formula: FV = PMT × [((1 + r)ⁿ − 1) ÷ r], where PMT is the annual extra contribution, r is the annual return divided by compounding periods, and n is the number of remaining years. Results are shown in nominal (not inflation-adjusted) dollars.

2026 Catch-Up Limits by Age

Under the SECURE 2.0 Act, catch-up rules now depend on your age bracket:

Ages 50-59: 401(k) standard catch-up of $7,500 above the base $23,500 limit, for a total of $31,000.
Ages 60-63: An enhanced super catch-up of $11,250 above the base limit, for a total of $34,750. This higher amount applies only during this four-year window.
Ages 64+: Returns to the standard $7,500 catch-up for a total of $31,000.
IRA catch-up (age 50+): An extra $1,000 on top of the $7,000 base limit, for a total of $8,000.

SIMPLE IRA and SIMPLE 401(k) plans have their own catch-up amounts indexed separately by the IRS. Always verify current figures at IRS.gov before filing.

Who Benefits Most from Catch-Up Contributions

Catch-up provisions were designed for workers who started saving late or had years of lower income that prevented maximizing contributions earlier. They are equally valuable for anyone who simply wants to accelerate tax-advantaged savings in the decade before retirement, when income is often at its peak and children may be off the payroll.

The earlier in your eligibility window you start using catch-up contributions, the more compounding amplifies the benefit. A worker who begins at 50 and saves the extra $7,500 each year at 7% return will add more than $100,000 to their balance by age 65 compared with someone who contributes at the base limit only. The 60-63 super catch-up window is particularly powerful: the higher ceiling for just four years can add an additional $15,000-$20,000 in growth by retirement if invested promptly.

Roth vs. Traditional Catch-Up

Catch-up contributions can go into either a traditional (pre-tax) or Roth (after-tax) account, depending on your plan options and income. High earners should note that starting in 2026, the IRS requires catch-up contributions for employees earning more than $145,000 in the prior year to be made to a Roth account within the same plan. This means the tax deduction disappears for high earners making catch-ups, but the contributions grow entirely tax-free.

If your income is below the threshold or you contribute to an IRA (not subject to this rule), you have the full Roth-versus-traditional choice. For most people in their 50s approaching peak earning years, the Roth catch-up is attractive because it locks in tax-free growth for potentially 20-30 years in retirement.

Strategy and Tips

Automate the increase: When you turn 50, update your payroll deferral election immediately so you capture the full catch-up for the entire year.
Use the super catch-up window deliberately: Ages 60-63 allow the highest contributions. If you have flexibility, consider reducing other spending categories in this window to maximize the larger limit.
IRA catch-up is separate: The $1,000 IRA catch-up is in addition to any 401(k) catch-up you take. Maxing both allows meaningful extra tax-advantaged savings.
Track the Roth mandate threshold: If you earn near $145,000, plan for the possibility that your catch-up must be Roth.

Tax laws change frequently. Verify current limits at IRS.gov and consult a qualified financial advisor before making retirement decisions.

Frequently Asked Questions

Do I have to use the full catch-up amount? No. You can contribute any amount up to the limit. Even a partial catch-up beats contributing nothing extra.

Does the employer match the catch-up? Employer match rules vary. Many plans match only up to the standard base deferral percentage, not the catch-up amount - check your Summary Plan Description.

Can I make a catch-up to a SEP IRA? No. SEP IRAs do not have catch-up provisions; only traditional and Roth IRAs and workplace plans do.
