How to Use This Calculator
- Enter your annual salary, contribution rate (% of salary), salary growth (% compounded once per year on salary), ages, and expected return (annual nominal rate; applied once per year on the balance, then contributions, matching NRIPage’s assumptions).
- Set current balance, employer match %, and the salary limit for match (only deferrals on the first X% of salary count toward the match in this model).
- Click Calculate, then review the chart and table; export with Excel or PDF.
Frequently Asked Questions
How is employer match calculated?
We apply your match rate to matchable deferrals: dollars you defer on the first X% of salary (the salary limit field), capped by what you actually defer. This is a simplified common pattern; your SPD may differ.
Does this include IRS contribution limits or catch-up?
No. Compare results to current-year 401(k) deferral limits and catch-up rules separately.
How does this compare to NRIPage’s 401(k) calculator?
NRIPage states that return is compounded annually while deposits are made monthly. For a flat salary, equal monthly deferrals sum to the same annual dollars we use; we apply the annual return to the balance, then add one year of employee and employer contributions, then step salary—so the default scenario matches NRIPage’s estimated balance (e.g. about $718,831.77 with $40,000 salary, 10% contribution, 0% raise, ages 30–65, 7% return, 50% match on 6% of pay, $0 starting balance).
