401K Calculator

Existing balance: your starting balance (plus extra savings if included) grows each period at the net return; it is not counted as a contribution.
Employee contributions: a percentage of that year\'s salary (or a fixed dollar amount), optionally increased each year by a number of percentage points (or dollars), stopping at the maximum if you set one. Contributions are limited by the annual deferral limit you enter, plus catch-up if enabled.
Employer match: Salary x min(your contribution rate, match cap) x match rate, plus the optional second tier on the next slice of salary. The match is based on the contribution you actually make after limits, and the employee limit is never applied to the match.
Salary and limits: salary grows once a year starting with year 2. Your limit stays flat unless you enter a yearly growth rate.
Returns and fees: the return you enter is gross. Each period, growth = balance x return and fees = balance x fee. Net growth (growth minus fees) is what appears as investment growth. Fees are shown separately and never subtracted twice.
Timing:
Inflation: Real value = Future balance / (1 + inflation) ^ years until retirement. Future dollars may buy less than today\'s dollars. This is only a display adjustment and is not applied to the account balance.
