What is a catch-up contribution?
A catch-up contribution is the extra amount the IRS lets you add to a retirement account once you turn 50, on top of the regular annual limit. This catch-up contribution calculator shows what those extra dollars grow to by projecting your regular contribution plus the catch-up over the years you keep saving — the balance updates as you type. The idea is simple: later in your career, when earnings often peak and the kids' costs fall away, the rules let you accelerate.
In 2025 the standard catch-up is $7,500 for 401(k), 403(b), and governmental 457(b) plans, and $1,000 for IRAs. SECURE 2.0 adds a bigger super catch-up of $11,250 for people aged 60 to 63. This page explains each tier and, more importantly, what a decade or so of those extra contributions can compound into.
How catch-up growth is calculated
The calculator adds your regular contribution and your catch-up into one annual total, then compounds that total once a year at your expected return for the number of years you keep contributing. Because the contributions go in over time, each year's deposit compounds for a different length — the first has the most years to grow.
How to use the catch-up contribution calculator
- Regular contribution limit. Your base annual deferral — up to $23,500 for a 2025 workplace plan, or $7,000 for an IRA.
- Catch-up (age 50+). The extra you add: $7,500 for a workplace plan, $11,250 if you are 60–63, or $1,000 for an IRA.
- Years contributing. How many years you keep up the catch-up — often the stretch from 50 to retirement.
- Expected return. A long-run average for your investments; 6–7% is a common planning figure.
A worked catch-up example
Lena turns 50 and decides to max her 401(k): a $23,000 regular contribution plus the $7,500 catch-up — $30,500 a year — for 10 years at a 7% return. These are the calculator's default inputs.
Step 1 — Combine into an annual total
$23,000 + $7,500 = $30,500 a year. The calculator compounds this total annually for 10 years at 7%.
Step 2 — Read the result
Step 3 — Isolate the catch-up's contribution
How much of that came from the catch-up alone? Re-run with the catch-up as the only contribution: $7,500 a year for 10 years at 7% compounds to about $103,600. So the over-50 boost — money Lena couldn't have contributed before turning 50 — is worth roughly a quarter of the final balance. That is the whole point of catch-ups: a modest extra, started late, still builds a six-figure cushion.
2025 catch-up contribution limits by tier
Catch-ups differ by account type and by age. The SECURE 2.0 super catch-up for ages 60–63 is the newest tier and the most valuable.
| Account / age | Regular limit (2025) | Catch-up | Total possible |
|---|---|---|---|
| 401(k)/403(b)/457(b), age 50–59 | $23,500 | +$7,500 | $31,000 |
| 401(k)/403(b)/457(b), age 60–63 | $23,500 | +$11,250 | $34,750 |
| 401(k)/403(b)/457(b), age 64+ | $23,500 | +$7,500 | $31,000 |
| IRA, age 50+ | $7,000 | +$1,000 | $8,000 |
2025 IRS limits. The $11,250 super catch-up applies only in the years you are 60–63; it reverts to $7,500 at 64. Source: IRS IR-2024-285.
Note the quirk at the top: the super catch-up is a four-year window. At 60–63 you can add $11,250; once you turn 64 the catch-up drops back to $7,500. Those four enhanced years are worth front-loading if your cash flow allows.
IRS — 401(k) limit increases to $23,500 for 2025 (IR-2024-285): confirms the $7,500 and $11,250 catch-up tiers and the $1,000 IRA catch-up.What extra years of catch-ups compound to
The power of a catch-up is not the annual dollar amount — it is the dollar amount times years of compounding. The table follows a $7,500 annual catch-up at 7%, showing how the extra-contribution pot grows the longer you keep it up.
| Years of catch-ups | Total extra contributed | Future value | Growth |
|---|---|---|---|
| 5 | $37,500 | $43,131 | $5,631 |
| 10 | $75,000 | $103,623 | $28,623 |
| 15 | $112,500 | $188,468 | $75,968 |
| 20 | $150,000 | $307,466 | $157,466 |

Catch-up contribution vs. the regular limit
A catch-up is not a separate account or a different plan — it is simply extra room in the same 401(k), 403(b), 457(b), or IRA you already have, unlocked by age. It applies per type of plan, so a 50-year-old with both a 403(b) and a governmental 457(b) gets a catch-up in each.
- The regular limit is what anyone can contribute regardless of age — $23,500 in a workplace plan, $7,000 in an IRA for 2025.
- The catch-up stacks on top of that once you reach 50 — you must actually be 50 by year-end to use it.
- The super catch-up replaces the standard catch-up only in the years you are 60–63.

Catch-up mistakes to avoid
- Assuming the super catch-up lasts past 63. The $11,250 tier covers only ages 60–63. At 64 it reverts to $7,500.
- High earners and the Roth catch-up rule. Under SECURE 2.0, catch-ups for high earners (above a wage threshold) must be made as Roth (after-tax) contributions — a rule still being phased in. Confirm how your plan handles it.
- Eligibility timing. You qualify for the age-50 catch-up in the calendar year you turn 50, even if your birthday is in December — but not a year early.
- Treating the projection as guaranteed. This calculator uses a constant return and ignores fees and taxes; real results will vary.
Accuracy, assumptions, and sources
This catch-up contribution calculator adds your regular and catch-up amounts into one annual total and compounds it annually at a constant return for the years you specify. It assumes steady contributions, a fixed return, and no fees or taxes on growth, so treat the output as a planning estimate, not financial advice. Catch-up eligibility, the Roth catch-up requirement for high earners, and the exact limits change over time — confirm the current figures with the IRS or a qualified adviser before acting.
