How Our Retirement ROI Calculator Works
Our retirement ROI calculator projects retirement savings using compound interest formulas with regular contributions. The calculation applies time value of money principles to model wealth accumulation over your working years, helping you plan for a secure retirement.
The Retirement Savings Formula
FV = PV(1 + r)^n + PMT × ((1 + r)^n - 1) / r × (1 + r)Where: FV = Future Value, PV = Present ValuePMT = Monthly Payment, r = monthly rate, n = monthsROI = (Investment Gains / Total Contributions) × 100The calculator compounds returns monthly, adding the future value of current savings and regular contributions. It shows how much you'll have at retirement, separating your contributions from investment gains to demonstrate the power of compound interest over long time horizons.
Shows exponential growth of retirement savings with compound interest over time
Mathematical Foundation
Retirement planning calculations are based on compound interest theory and the time value of money from financial mathematics. The formula accounts for both lump-sum savings growth and the accumulated value of regular contributions (annuity). Starting early dramatically increases final wealth due to exponential compound growth—even modest contributions over 30-40 years can build substantial retirement wealth. The calculator helps visualize the critical relationship between time, contributions, and returns.
- Compound interest creates exponential retirement wealth growth
- Starting early maximizes time for compounding to work
- Regular contributions leverage dollar-cost averaging
- Investment gains often exceed total contributions over long periods
- Even small monthly increases significantly boost retirement savings
- Higher returns dramatically impact final retirement portfolio value
