How Retirement Savings Are Projected
This uses compound growth with regular contributions:
FV = PV(1+r)^n + PMT × [(1+r)^n - 1] / r
The 7% average annual return is a common assumption based on historical stock market performance (adjusted for inflation it is ~4-5%).
Example Calculation
Age 30, plan to retire at 65, $50,000 saved, contributing $500/month at 7% return.
- 01Years to retirement = 65 - 30 = 35 years (420 months)
- 02Monthly rate = 7% / 12 = 0.583%
- 03Current savings grow to: $50,000 × 1.00583^420 = $574,464
- 04Contributions grow to: $500 × (1.00583^420 - 1) / 0.00583 = $893,769
- 05Total at retirement = $574,464 + $893,769 = $1,468,233
