What is the 2026 401(k) contribution limit?

The 2026 401(k) employee elective deferral limit is $24,500 for those under 50, and $32,500 total ($24,500 + $8,000 catch-up) for those 50 and older. High earners ($145K+ single, $290K+ married) must make catch-up contributions as Roth in 2026.

How much employer match am I leaving on the table?

If you contribute less than your employer's match limit (e.g., 6% of salary), you leave free money on the table. A 50% match on 6% means you get 3% of salary free—on $85K that's $2,550 annually. Always contribute at least enough to maximize the match.

Should I choose Traditional or Roth 401(k)?

Traditional 401(k) reduces taxable income now—good if you expect a lower tax bracket in retirement. Roth 401(k) uses after-tax dollars but grows tax-free—better if you expect higher taxes later or are early in your career. High earners ($145K+) must use Roth for catch-up contributions in 2026.

What are catch-up contributions for 401(k)?

Catch-up contributions allow those 50 and older to contribute an extra $8,000 in 2026, for a total of $32,500. SECURE 2.0 adds a higher catch-up ($11,250) for ages 60-63. If you earn over $145K (single) or $290K (married), catch-up must be Roth.

How do I calculate my projected 401(k) balance at retirement?

The calculator uses compound growth: FV = PV(1+r)^n + PMT × [((1+r)^n - 1) / r], where PV is current balance, PMT is monthly contribution, r is monthly return rate, and n is months to retirement. Typical assumptions: 6-8% annual return, adjusted for inflation.

When should I increase my 401(k) contribution?

Increase contributions when you get a raise, pay off debt, or reduce expenses. Aim to contribute at least enough for full employer match first, then work toward maxing the annual limit. Front-loading early in the year can maximize time in the market.

Key Formulas

Employer Match

Employer Match = Employee Contribution × Match Percentage (up to match limit percentage of salary)

Catch-Up = $8,000 (if age 50+, up to annual limit). High earners ($145K+ single, $290K+ married) must contribute catch-up as Roth in 2026.

Future Value with Compound Interest

FV = PV × (1 + r)^n + PMT × [((1 + r)^n - 1) / r]

Tax Savings (Traditional)

Tax Savings = Employee Contribution × Marginal Tax Rate (typically 22-24% for middle-income earners)
