About the 401(k) Calculator

A 401(k) is an employer-sponsored retirement account funded through payroll deductions, often with an employer match up to a set percentage of pay. This calculator projects the account balance from your contribution rate, salary, any employer match, an assumed return, and years until retirement.

The projection is illustrative. Actual outcomes depend on investment performance, future contribution limits, salary changes, and the plan’s specific match formula and vesting schedule.

How this works

FV = B(1+r)ⁿ + (E + M)·[((1+r)ⁿ − 1)/r], where E = your contribution, M = employer match.

Assumptions

The employer matches your full contribution up to the match percentage of salary.
Salary and contribution rate stay constant.
Returns are a fixed average; actual returns vary.

Frequently asked questions

What is an employer match?

Money your employer adds to your 401(k) based on your own contributions, for example 50% of the first 6% of salary you contribute. Match rules and vesting vary by plan.

What is the contribution limit?

The IRS sets an annual employee contribution limit that changes over time, with an additional catch-up amount allowed at age 50 and older.

What is vesting?

Vesting is how much of the employer contributions you keep if you leave. Your own contributions are always 100% yours.
