Formula:
The 401k retirement balance is calculated using a combination of the future value of a lump sum (your current balance) and the future value of an annuity (your monthly contributions plus employer match).
- FV = Future Value (Estimated 401k Balance)
- PV = Current 401k Balance
- C = Total Monthly Contribution (Your Contribution + Employer Match)
- Rannual = Annual Rate of Return (as a decimal)
- Rmonthly = Monthly Rate of Return (Rannual / 12)
- Y = Years to Retirement
- N = Total Number of Months (Y * 12)
Formula Approximation:
FV = PV * (1 + Rmonthly)N + C * [((1 + Rmonthly)N - 1) / Rmonthly] * (1 + Rmonthly)
This formula estimates your balance assuming monthly contributions at the beginning of each period and monthly compounding.
