How the 401(k) Calculator Works
This calculator projects your retirement savings using compound growth on both your existing balance and future contributions.
Formula
FV = PV × (1 + r)^n + PMT × [(1 + r)^n − 1] / r
Where:
Employer match is calculated as: Salary × Match Limit % × Match Rate %.
Example Calculation
$50,000 current balance, $19,500/yr contribution, 50% employer match up to 6% of an $85,000 salary, 7% return, 25 years.
- 01Employer match = $85,000 × 6% × 50% = $2,550/yr
- 02Total annual = $19,500 + $2,550 = $22,050
- 03Current balance growth = $50,000 × (1.07)^25 = $271,372
- 04Contribution growth = $22,050 × [(1.07)^25 − 1] / 0.07 = $1,393,751
- 05Projected balance = $271,372 + $1,393,751 = $1,665,123
