Calculate how much extra retirement wealth you generate by maxing the age-50+ catch-up — and the SECURE 2.0 super catch-up at ages 60-63 — across 401(k) and IRA accounts (2026 limits).
A 55-year-old who maxes the $7,500 401(k) catch-up for 10 years at 7% real return generates an extra ~$112,000 of retirement wealth. The IRA $1,000 catch-up over the same horizon adds ~$15,000. Ages 60-63 get the SECURE 2.0 super catch-up of $11,250 instead of $7,500, lifting the bonus even higher.

2026 IRS limits (estimated). 401(k): $23,000 regular + $7,500 catch-up = $30,500 for ages 50-59. The SECURE 2.0 super catch-up brings ages 60-63 to $23,000 + $11,250 = $34,250 (instead of $30,500). IRA: $7,000 regular + $1,000 catch-up = $8,000 across all ages 50+. Confirm against IRS Rev. Proc. annual update.
Why catch-up exists. Congress added catch-up contributions in EGTRRA 2001 to give workers approaching retirement an opportunity to make up for years of under-saving. The recurring data: most Americans hit peak earning power between ages 45-60 but cumulative retirement savings often lag — catch-up lets the income surge translate into retirement security.
SECURE 2.0 super catch-up (ages 60-63). The SECURE 2.0 Act of 2022 created an enhanced catch-up of $11,250 for workplace plans covering ages 60-63 inclusive. After age 64 the catch-up reverts to the regular $7,500. The 4-year window is uniquely valuable: it's after most child-rearing expenses, before RMDs kick in at 73, and during typical peak earning years. Max these years if at all possible.
The high-earner Roth rule. Starting in 2026 under SECURE 2.0, workers earning over $145,000 from the same employer in the prior year must make their catch-up contributions to a Roth account (post-tax), not pre-tax. The dollar limit is the same; only the tax treatment changes. For high earners this can be a significant cash-flow shift — Roth contributions don't reduce current-year taxable income.
What 7% real return implies. A 7% real (after-inflation) return is roughly the historical US equity-market premium and a reasonable mid-case assumption for a 60/40 portfolio. Plugging in 5% real is more conservative; 9% is optimistic. The catch-up bonus scales linearly with return assumptions over short horizons (10-15 years) and exponentially over longer ones.
A 55-year-old has been contributing $23,000 (the regular max) to a 401(k) and now decides to add the $7,500 catch-up for the next 10 years until retirement at 65. Expected real return: 7%.
Without catch-up. $23,000 × ((1.07^10 − 1) / 0.07) = $23,000 × 13.816 = $317,768 in the regular-contribution path. Total contributed across 10 years: $230,000. Growth multiple: about 1.38× contributed.
With catch-up. $30,500 × 13.816 = $421,388. Total contributed: $305,000. Extra wealth from catch-up: $421,388 − $317,768 = $103,620. The extra dollars contributed were $75,000 ($7,500 × 10 years), so the catch-up generated roughly $28,620 of compound growth on top of the principal contributed.
Now extend with the SECURE 2.0 super catch-up. The same person at age 60-63 gets four years of $11,250 catch-up (instead of $7,500). For those four years, contributions become $34,250 each (vs $30,500). Extra wealth across the 60-63 window relative to the regular catch-up is approximately $15,000 of additional compounded value — small but meaningful, and entirely free money the IRS allows.
What if they also max IRA. Add $8,000/year ($7,000 regular + $1,000 catch-up) for the same 10-year window: $8,000 × 13.816 = $110,528 additional wealth. Without the $1,000 IRA catch-up: $7,000 × 13.816 = $96,712. IRA catch-up bonus: $13,816 extra wealth on $10,000 of extra contribution.
