The employee elective deferral cap for a regular 401(k), 403(b), or most 457(b) plans is $24,500 in 2026. Age 50+ adds $8,000 (total $32,500). Ages 60-63 add $11,250 (total $35,750) if the plan allows the SECURE 2.0 extra.
The empty-plan leftover is already written: $10,000 YTD → $14,500. Halfway leftover: $12,250 YTD at age 41 → $12,250. Mid-year leftover: $15,000 YTD at age 40 → $9,500. Late-year leftover: $18,500 YTD at age 43 → $6,000. This page is the early-year leftover: $8,000 already deferred.

After $24,500 the IRA is still a separate cap: 401(k) maxed, IRA still $7,500. Hub: United States calculators.
This engine only subtracts YTD from the IRS 402(g) ceiling plus age-based catch-up. Your plan can cap below that. Employer match does not use this room. Estimate, not tax advice.
Direct answer: $8,000 YTD → $16,500 at age 44
- Regular 2026 base = $24,500
- Age 44 catch-up = $0
- Room = $24,500 − $8,000 = $16,500
- Age 54 = $32,500 − $8,000 = $24,500
- Age 61 = $35,750 − $8,000 = $27,750
limit = $24,500 + ($8,000 if 50–59 or 64+, or $11,250 if 60–63)
remaining = max(0, limit − YTD deferrals)
Same $8,000 YTD, three ages
| Age | Catch-up | Elective limit | Room after $8,000 |
|---|---|---|---|
| 44 | $0 | $24,500 | $16,500 |
| 54 | $8,000 | $32,500 | $24,500 |
| 61 | $11,250 | $35,750 | $27,750 |
A SIMPLE plan after $8,000 still has $9,000 under the $17,000 under-50 cap. That leftover is already written: SIMPLE room after $8,000. This page is the regular 402(g) cap.
What this is not
- The $10,000, $12,250, $15,000, or $18,500 YTD leftovers. Those still have $14,500, $12,250, $9,500, and $6,000 under 50. This page starts at $8,000.
- Employer match math. Match is a separate bucket. 50% of 3% on $60,000.
- An IRA. Traditional / Roth IRA room is $7,500 (or $8,600 at 50+).
Yes, if YTD is $8,000 and the plan uses the regular 402(g) cap. Confirm payroll coding and any plan-level ceiling.
Age 50+ adds $8,000 of regular catch-up. $32,500 − $8,000 = $24,500.
No. Employer match does not count against the $24,500 elective limit.
