US 401(k) & IRA Contribution Calculator
Pre-tax 401(k) and traditional-IRA contributions cut your federal taxable income. Enter your salary and age and PayGlance shows the most you can put in this year with tax relief, and the tax it saves.
How to use it
- Enter salary and age. Age sets whether you get the 50-plus catch-up on top of the standard limits.
- Add a contribution (optional). Or leave blank to see the maximum tax-advantaged amount.
- See the tax saved. PayGlance shows the relievable amount, federal tax saved and net cost.
FAQs
How much can I contribute in 2026?
The 401(k) elective deferral limit is $24,500, plus an $8,000 age-50 catch-up. A traditional IRA adds up to $7,500 ($8,600 with the age-50 catch-up). Employer matching is on top of your own deferral. Figures are the published/projected IRS limits - confirm the current year's numbers with the IRS.
Is a 401(k) pre-tax for everything?
A traditional 401(k) is pre-tax for federal (and usually state) income tax, but it is still subject to Social Security and Medicare - those come out of your full pay. A traditional IRA is not payroll-related.
Does the IRA deduction always apply?
Traditional-IRA deductibility phases out at higher incomes if you or your spouse are covered by a workplace plan. This calculator shows the contribution limit, not your personal deductibility phase-out - check the IRS thresholds for your situation.
