Super Catch-Up Retirement Window Calculator (2026)
See how much extra you can save during the SECURE 2.0 super catch-up window (ages 60–63) and what it is worth at retirement versus the standard $8,000 limit.
SECURE Act 2.0 created a four-year "super catch-up" window for workers aged 60, 61, 62, and 63: instead of the standard $8,000 catch-up contribution limit, you can contribute up to $11,250 per year beyond the base $23,500 limit — a $3,250 annual bonus that disappears the moment you turn 64. This calculator shows whether you qualify, how much extra you can save during your window, and what those contributions are worth at retirement compared to the standard catch-up limit.
How the Super Catch-Up Window Works
The Four-Year Window
SECURE Act 2.0 (effective January 1, 2025) amended IRC § 414(v)(2)(E) to create a higher catch-up limit for a specific four-year window. The ages that qualify — 60, 61, 62, and 63 — were chosen deliberately: they represent the final sprint before traditional retirement age, when workers have the highest earnings and the most runway for contributions to compound.
2026 contribution limits by age:
| Age by Dec 31 | Catch-up limit | Total 401(k) capacity | |---|---|---| | Under 50 | $0 | $23,500 | | 50–59 | $8,000 | $31,500 | | 60–63 | $11,250 | $34,750 | | 64+ | $8,000 | $31,500 |
The super catch-up is $3,250 more per year than the standard catch-up — not enormous on its own, but compounded over four years and then grown to retirement, the difference is meaningful.
What the Calculator Shows
For each year between now and retirement, the calculator builds the accumulated value of your catch-up contributions under two scenarios:
- Super catch-up scenario: $11,250/year during your 60–63 window, then $8,000/year after
- Standard catch-up scenario: $8,000/year throughout
The difference at retirement is what you gain by fully using the window.
The Mandatory Roth Interaction
If you earn $150,000 or more in FICA wages, your catch-up must be designated as Roth. This does not change the dollar amounts — it changes the tax timing. The calculator flags this and links to the Mandatory Roth Catch-Up Calculator for a full break-even analysis.
When to Use This Calculator
When you turn 60. This is the most important moment. You are entering the window — use this calculator to understand exactly how many years you have and what the full window is worth if you max it out. Adjust your payroll deferrals immediately.
When you are 62 or 63 and haven't been maxing out. The window is closing. Even if you can't max the full $34,750, increasing your deferral to capture as much of the $11,250 catch-up as possible in your remaining window years has compounding value for the years until retirement.
When evaluating whether to delay retirement by one year. Delaying retirement from 63 to 64 has two effects: one more year of super catch-up contributions AND one more year of compounding before withdrawal. This calculator shows the first effect; combine it with your full retirement projection to evaluate the trade-off.
When your HR department sends a benefits update. Many workers receive enrollment reminders that mention catch-up contributions but don't distinguish between the standard and super limits. Use this calculator to confirm whether you qualify for the higher amount and whether your current deferral election is set correctly.

Understanding the Inputs
- Your Age (by Dec 31, 2026)
- Your age as of December 31 determines which catch-up limit applies. The super catch-up of $11,250 applies only to ages 60, 61, 62, and 63. At age 64, the limit permanently reverts to the standard $8,000. Ages 50–59 and 64+ receive the standard catch-up. Under 50: no catch-up eligible.
- Years Until Retirement
- How many years until you plan to stop working and begin drawing down your retirement accounts. This determines how long your contributions have to compound. The longer the horizon, the more valuable each additional year of catch-up contributions becomes due to compounding.
- Expected Annual Return
- The nominal annual return you expect inside your 401(k) or 403(b). This applies equally to both the super and standard catch-up scenarios since the money grows in the same account type. Historical nominal return for a 60/40 portfolio is roughly 7–8%. Use a conservative 6% if you are approaching retirement and shifting to bonds.
- Prior-Year FICA Wages (W-2 Box 3)
- Used to determine whether the mandatory Roth catch-up rule applies to you. If your FICA wages from the employer sponsoring your plan were $150,000 or more in the prior year, your entire catch-up contribution — including the super catch-up — must be designated as Roth under SECURE 2.0 Section 603. Enter 0 if you are self-employed with a Solo 401(k) or if your wages were below the threshold.
