How it works
Each month: Balance = Balance × (1 + r) + Employee contribution + Employer match, where r is the monthly return rate.
Employee contribution = Salary × contribution % ÷ 12.
Employer match = Salary × min(contribution %, match limit %) × match % ÷ 12.
Salary grows once per year by the annual salary increase rate.
Example
A 30-year-old earning $75,000 contributes 10% with a 50% employer match up to 6% of salary, starting from a $25,000 balance at 7% annual return and 3% yearly raises. By age 65:
Projected 401(k) balance ≈ $2.36M — about $453K from your contributions, $136K from employer match, and $1.74M from investment growth.
