401(k) and IRA contribution room calculator (2026)
Enter your age, filing status, modified AGI and what you have already contributed this year. The calculator shows your remaining 2026 room using IRS limits.
How it works
For 2026 the employee deferral limit for 401(k), 403(b), governmental 457 plans and the Thrift Savings Plan is $24,500. Workers aged 50 or over can add an $8,000 catch-up, and those aged 60 to 63 get a higher $11,250 catch-up instead.
The IRA limit is $7,500, plus a $1,100 catch-up at 50+, and it can never exceed your taxable compensation. It is a combined limit across all your traditional and Roth IRAs. Direct Roth IRA contributions phase out between $153,000 and $168,000 of modified AGI for single filers and heads of household, and between $242,000 and $252,000 for married couples filing jointly.
Not included: employer contributions and the overall annual additions limit, plan-specific caps, SIMPLE and SEP plans, and the traditional IRA deduction phase-out (shown for reference only).
Figures used
| 401(k)/403(b)/457/TSP deferral | $24,500 |
|---|---|
| Catch-up age 50+ | $8,000 |
| Catch-up age 60–63 | $11,250 |
| IRA limit | $7,500 (+$1,100 at 50+) |
| Roth IRA phase-out | Single/HoH $153,000–$168,000; MFJ $242,000–$252,000; MFS (lived with spouse) $0–$10,000 |
| Traditional IRA deduction phase-out (covered by workplace plan) | Single $81,000–$91,000; MFJ $129,000–$149,000 |
The formula
Roth reduction (IRS Pub 590-A Worksheet 2-2): ratio = (MAGI − lower) / (upper − lower) rounded to 3 decimals; reduced = limit − ratio × limit, rounded up to the next $10, with a $200 minimum while MAGI is below the upper limit; $0 at or above the upper limit.
Worked example
A 55-year-old can defer up to $32,500 into a 401(k) ($24,500 + $8,000) and put up to $8,600 into IRAs. A 61-year-old's 401(k) limit is $35,750. A 45-year-old single filer with $160,000 MAGI is 46.7% of the way through the Roth phase-out: $7,500 − $3,502.50 = $3,997.50, rounded up to a Roth limit of $4,000.
Frequently asked questions
Do employer matching contributions count toward the $24,500?
No. The $24,500 limit is for your own elective deferrals. Employer contributions count toward a separate, higher overall limit.
Can I contribute to both a 401(k) and an IRA?
Yes. They have separate limits. Being covered by a workplace plan can limit whether traditional IRA contributions are tax-deductible, but not whether you can make them.
What counts as modified AGI?
For Roth purposes it is your AGI with certain items added back, as set out in IRS Publication 590-A, Worksheet 2-1. Use that worksheet if you are near the phase-out range.
