How It Works
This calculator projects your 401(k) balance using monthly compounding with employee contributions, employer matching, and investment returns.
Monthly compounding
Each month: \(\text{Balance} = \text{Balance} \times (1 + r/12) + \text{Monthly Contribution} + \text{Monthly Match}\)
Where r is the annual return rate as a decimal (7% = 0.07).
Employee contribution
Your annual contribution = salary x contribution percentage, capped at the IRS limit ($23,500 for 2024, or $31,000 for age 50+).
Employer match
The employer matches a percentage of your contribution, but only up to a certain percentage of your salary. For example, “50% match on the first 6%” means the employer contributes 50% of what you put in, on up to 6% of your salary.
For a $100,000 salary with a 50% match on the first 6%: the matchable amount is $6,000 (6% of salary). If you contribute at least $6,000, the employer adds 50% x $6,000 = $3,000 per year.
Worked example
Age 30, retire at 65, salary $100,000, 10% contribution, 50% match on 6%, 7% return. Annual employee contribution = $10,000 (under the $23,500 limit). Annual employer match = 50% of $6,000 = $3,000. Monthly contribution = $833.33. Monthly match = $250. Monthly return = 0.07/12 = 0.005833. Over 35 years (420 months), the balance grows to approximately $1.6 million. Of that, approximately $350,000 comes from your contributions, $105,000 from employer matching, and $1.15 million from investment growth.
