Projected 401(k) Balance vs Years Until Retirement

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:

  • PV = Current balance
  • PMT = Annual contribution + employer match
  • r = Annual rate of return
  • n = Years until retirement
  • Employer match is calculated as: Salary × Match Limit % × Match Rate %.

    Lösungsbeispiel

    $50,000 current balance, $19,500/yr contribution, 50% employer match up to 6% of an $85,000 salary, 7% return, 25 years.

    1. 01Employer match = $85,000 × 6% × 50% = $2,550/yr
    2. 02Total annual = $19,500 + $2,550 = $22,050
    3. 03Current balance growth = $50,000 × (1.07)^25 = $271,372
    4. 04Contribution growth = $22,050 × [(1.07)^25 − 1] / 0.07 = $1,393,751
    5. 05Projected balance = $271,372 + $1,393,751 = $1,665,123
