Estimated Retirement Savings
Retirement savings are calculated using the future value of a series formula combined with compound growth on existing savings:
Future Value = PV × (1 + r)^n + PMT × [((1 + r)^n - 1) / r]
Where:
- PV = Present value (current savings)
- PMT = Monthly contribution
- r = Monthly interest rate (annual rate / 12)
- n = Number of months until retirement
Key takeaways:
- Starting early is the most powerful factor — even small contributions grow dramatically over decades
- A 25-year-old saving $500/month at 7% will have ~$1.2 million by age 65
- A 35-year-old needs ~$1,000/month to reach the same goal
- Increasing contributions by just 1% of salary each year can add hundreds of thousands to your total
