Catch-Up Contribution Calculator (2026)

The short answer

Catch-up contributions buy more than the dollars you deposit.

The direct benefit is the additional amount placed in the account. The longer-term benefit may include compound growth on those dollars. The calculator separates the two, keeps all results in today’s dollars, and does not pretend a steady return is a market forecast.

How the calculator works

We project the same regular annual contribution along two paths. One path stops at the regular contribution; the second adds the maximum catch-up available for each age. Both use the same return, fee, inflation, and retirement date. Their difference is the estimated value attributable to catch-up contributions.

Which 2026 catch-up applies?
Age reached in 2026	Catch-up	Potential employee total
Under 50	Not available	$24,500
50–59	$8,000	$32,500
60–63	$11,250	$35,750
64+	$8,000	$32,500

The limit is not the same as an automatic contribution

Your employer plan must permit catch-ups, and enough compensation must remain in payroll to fund them. A late-year election may not leave enough paychecks. Employer matching formulas also vary: the calculator excludes matching so that it does not invent a benefit your plan may not provide.

The Roth catch-up rule for some higher-paid workers

For 2026, the prior-year wage threshold is $150,000. If 2025 FICA wages from the employer sponsoring the plan exceeded that threshold, catch-up contributions for 2026 may generally need to be designated Roth. This rule concerns the tax character of the catch-up; it does not create a second investment limit. Confirm payroll treatment with the plan administrator.

How to read the graphics

The two-line chart emphasizes the account paths, while the age bars make the temporary 60–63 increase visible. Labels and line styles accompany color, so the result does not depend on color recognition alone. On a phone, the visualization scales down while detailed tables remain horizontally scrollable inside their own container.

Catch-up contribution FAQ

Who can make catch-up contributions in 2026?

A participant who reaches age 50 or older by the end of 2026 may generally use an age-based catch-up if the employer plan permits it and compensation is sufficient.

What is the 2026 401(k) catch-up limit?

The standard workplace-plan catch-up is $8,000. Someone who reaches age 60, 61, 62, or 63 during 2026 may use the higher $11,250 limit instead.

Does the higher age-60 catch-up continue after age 63?

No. Under current law, the special window covers ages 60 through 63. The standard age-50 catch-up generally applies again at age 64.

Does my employer have to offer catch-up contributions?

No. The federal limit does not force every plan to offer the feature. Check the plan document and payroll deadlines.

Are catch-up contributions always Roth?

Not always. For 2026, certain workers whose prior-year FICA wages from the sponsoring employer exceeded $150,000 generally must make catch-up contributions as Roth. Employer-specific wages and plan implementation matter.
