401(k) growth and the employer match

The match is the heart of a 401(k) — contributing below the cap leaves part of your pay on the table. Set your contribution rate, the match formula, expected raises and return to project the balance at retirement, and see any match you are currently missing.

How to use this calculator

  1. Enter the current account balance and salary, then reproduce the employer's match wording carefully.
  2. Set your employee contribution at least high enough to capture the full available match when affordable.
  3. Review the annual employee limit warning and test a lower-return case for the selected investments.

How to read the result

Employee deposits, employer deposits and investment growth are shown separately. A missed-match amount means the selected contribution rate is below the rate needed to earn the full modeled employer contribution.

What this estimate does not capture

Vesting schedules, plan fees, Roth versus traditional tax treatment and the special age 60–63 catch-up are outside this simplified projection. Confirm current rules with the plan administrator.

Methodology, assumptions & limits

Inputs are applied directly to standard finance formulas with monthly compounding where relevant. Results are estimates in the selected currency; they do not include every tax, fee, benefit, market event or local rule. Try a conservative and an optimistic case before making a decision.

Frequently asked questions

How much should I contribute?

At minimum, contribute up to the full match. A common target is 15% of income once you can manage it.

What does "50% up to 6%" mean?

Your employer adds 50 cents per dollar you contribute, up to 6% of salary — so contributing 6% earns an extra 3% of pay.

What is the contribution limit?

For 2026 the employee deferral limit is $24,500, with an $8,000 catch-up from age 50. Ages 60–63 may qualify for a higher special catch-up outside this simplified model.

What return should I assume?

For an equity-heavy portfolio, about 7% a year after inflation is a conservative long-run assumption.
