Beginning in 2026, certain higher-paid participants who make catch-up contributions may be required to make those catch-up contributions on a Roth basis. Eligibility depends on prior-year wages from the plan sponsor and the features of your employer's plan. This calculator does not determine that requirement.

What the 401(k) Growth calculator does
A 401(k) growth calculator projects the future value of an employer-sponsored retirement account, factoring in your employee traditional and Roth contributions, employer matching and profit-sharing, annual raises, fees and investment returns. It applies the correct IRS employee-deferral and catch-up limits for the year and your age.
How the calculation works
For the selected year and your age by year end, the tool applies the employee elective-deferral limit plus the age-based catch-up (standard for ages 50-59 and 64+, enhanced for ages 60-63). Employer match and profit-sharing are added but validated against the total defined-contribution plan limit. Each year the balance grows by your expected return net of fees.
Formula
Each year: Balance = Balance × (1 + return − fees) + employee deferral (capped at the age-based limit) + employer contributions (capped so the combined total stays within the plan limit).
What your results mean
In 2026 a participant under 50 can defer up to $24,500; ages 50-59 up to $32,500; ages 60-63 up to $35,750 (enhanced catch-up); age 64+ back to $32,500. Employer match and profit-sharing count toward the $72,000 total plan limit but not the employee-deferral limit.
Limitations: Contribution limits change yearly and are stored by year. Returns, raises, fees and continued employment are assumptions — projections are estimates, not guaranteed returns.

Frequently asked questions
In 2026 the standard catch-up for ages 50-59 and 64+ is $8,000, and the enhanced catch-up for ages 60-63 is $11,250. That raises the total employee deferral to $32,500 (ages 50-59 and 64+) or $35,750 (ages 60-63).
Only participants who are age 60, 61, 62 or 63 by the end of the calendar year qualify for the enhanced catch-up. At age 64 the limit reverts to the standard catch-up amount.
No. Employer matching and profit-sharing do not count against your employee elective-deferral limit, but they do count toward the total defined-contribution plan limit ($72,000 for 2026, plus any catch-up).
Yes. Traditional pre-tax and Roth employee deferrals share the same annual employee-deferral limit; you cannot contribute the full limit to each separately. Our guide on traditional vs Roth 401(k) explains how to split contributions.
The total defined-contribution limit combining employee and employer contributions is $72,000 for 2026 and $70,000 for 2025, excluding eligible catch-up contributions.
No. All projected returns, salary increases and ending balances are estimates based on your assumptions, not guaranteed outcomes.
The IRS reviews retirement-plan limits annually and adjusts them for inflation, so they typically change each year. This calculator stores limits by year so they can be updated without changing the logic.
