A catch-up contribution simulator shows the compounding difference between making no catch-up contributions, standard catch-up from age 50, and the new SECURE 2.0 super catch-up (ages 60-63). See exactly how much extra each tier adds to your retirement balance.

How the Catch-Up Contribution Simulator Works
Catch-up contributions are one of the most powerful but underused tools for late-career retirement savings. After age 50, the IRS allows you to contribute significantly more to tax-advantaged accounts. SECURE 2.0 (effective 2025) introduced an even larger "super catch-up" for ages 60-63. This simulator shows the compounding impact of each tier over your remaining working years.
The Three Contribution Tiers
The simulator compares three scenarios simultaneously. Scenario 1 (No Catch-Up) uses only your current contribution percentage — no additional catch-up even after you turn 50. Scenario 2 (Standard Catch-Up) adds $7,500/year to your contributions starting at age 50 (or immediately if you're already over 50). Scenario 3 (Max Catch-Up) uses standard catch-up from 50-59, then upgrades to the $11,250 super catch-up at ages 60-63, then reverts to $7,500 at 64+.
Why the Contribution Cap Matters
All three scenarios are capped at the actual IRS limits. If your salary times your contribution percentage already maxes out the $23,500 regular limit, additional catch-up on top of that is still applied correctly. The employer match (which doesn't count toward IRS limits) is added to all three scenarios equally, since employers don't typically match catch-up contributions.
The Super Catch-Up Window (Ages 60-63)
SECURE 2.0 created a unique 4-year window at ages 60, 61, 62, and 63 where the catch-up limit jumps from $7,500 to $11,250 — a $3,750 additional annual contribution. This may seem modest but compounds significantly. Contributing an extra $3,750/year for 4 years at 7% return, growing for 5 more years until 68, adds approximately $27,000-$32,000 to your balance. The simulator calculates this precisely for your retirement date.
Interpreting the Results
The chart shows all three balance trajectories from your current age to retirement. The gap between the lines widens each year due to compounding — extra contributions made early have more time to grow. Pay attention to the "Extra vs No Catch-Up" stat: for most people starting standard catch-up at 50 with a 15-year runway and 7% returns, the extra $7,500/year typically grows to $180,000-$220,000 in additional retirement savings. That's the compounding value of catch-up contributions visualized concretely.
FAQ
Is this catch-up contribution simulator free?
Yes, completely free with no signup required. All calculations run locally in your browser using 2026 IRS contribution limits.
What are the 2026 catch-up contribution limits?
For 2026: 401k regular limit is $23,500. Standard catch-up (ages 50-59 and 64+) adds $7,500 for a total of $31,000. The new SECURE 2.0 super catch-up (ages 60-63 only) adds $11,250 instead of $7,500, for a total of $34,750. IRA regular limit is $7,000; catch-up (50+) adds $1,000 for $8,000 total.
What is the super catch-up contribution for ages 60-63?
SECURE 2.0 (enacted 2022, effective 2025) created a higher catch-up limit for ages 60, 61, 62, and 63 specifically. For 2026, this super catch-up is $11,250 instead of the standard $7,500. At age 64 you revert to the standard $7,500 catch-up. This window is designed to help people in peak earning years maximize tax-advantaged savings before retirement.
How much does maximizing catch-up contributions add at retirement?
It depends on your starting age, but a person starting standard catch-up at 50 with a 7% return and retiring at 65 adds roughly $200,000-$300,000 in additional retirement savings. Adding the super catch-up in ages 60-63 can add another $40,000-$80,000 on top of that, depending on assumed returns.
Do catch-up contributions apply to IRAs too?
Yes — the IRA catch-up limit (age 50+) is $1,000 for 2026, making the total IRA limit $8,000. This simulator focuses on 401k catch-up contributions since those have larger limits. If you're eligible for both, consider maximizing both accounts, especially if you're in a high tax bracket where traditional IRA deductions help.
What if my employer plan doesn't allow catch-up contributions?
Most 401k, 403b, and 457 plans must allow catch-up contributions if the IRS permits them. However, some SIMPLE IRA plans have lower limits. Check your plan documents or ask your HR department to confirm your plan's specific limits and procedures for making catch-up contributions.
Are catch-up contributions pre-tax or Roth?
You choose — catch-up contributions follow the same rules as regular contributions. You can designate them as pre-tax (traditional) or Roth within your 401k plan, or split between both. Starting in 2026, high earners (income over $145,000) must make catch-up contributions to a Roth 401k if their plan offers one (SECURE 2.0 requirement).
