401k Calculator

Projects a 401(k) balance from the share of pay you defer and the match your employer adds on top, rather than from a flat dollar contribution. Enter your salary, your contribution percentage, the match formula such as 50% of the first 6% of pay, your current balance, an expected return and the years left, plus an optional raise that grows contributions with your pay. A second action prices the match alone: what your employer adds this year, the percentage that captures all of it, and what you leave behind by stopping short. Contributions land at the end of each year and the balance compounds annually, and the IRS deferral limit is an optional input rather than a built-in number, because it changes every year.
