PFCStart with this year's contributions
2026 401(k) contribution calculator
Compare employee contributions, employer matching, annual limits, and average contribution per paycheck.
Savings growth calculator
Explore deposits and growth at a constant APY. This is a general savings illustration, without retirement-account tax rules.
Contributions are one part of retirement planning
The 401(k) tool estimates a full year of contributions. It does not project retirement income or decide how much you need to retire. The savings calculator models constant APY; it does not model variable investment returns, withdrawals, or inflation.
How to Use Our 401(k) Calculator to Plan Your Retirement
Other retirement income sources
IRA eligibility, Social Security benefits, and pension income use different rules. The Roth IRA tool checks direct contribution room; the Social Security tool adjusts a supplied SSA estimate for claiming age; the pension tool illustrates a plan formula. The 401(k) tool handles annual contributions and matching.
