Retirement Calculator Couples Formula and Mathematical Explanation
The core logic of our retirement calculator couples relies on the Time Value of Money (TVM) principles. We calculate the future value of your current assets and your ongoing monthly contributions, compounded annually.
Step 1: Future Value of Current Savings
FV1 = PV * (1 + r)^n
Step 2: Future Value of Monthly Contributions
FV2 = PMT * [((1 + r/12)^(n*12) – 1) / (r/12)]
Step 3: Calculating Required Nest Egg
The retirement calculator couples uses the “Safe Withdrawal Rate” (SWR). If you need $X per year, you need a nest egg of X / 0.04. We adjust this $X for inflation over the years until your retirement date.
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| PV | Present Value (Current Savings) | Currency ($) | $0 – $5,000,000 |
| PMT | Monthly Payment (Contribution) | Currency ($) | $100 – $10,000 |
| r | Annual Rate of Return | Percentage (%) | 4% – 10% |
| n | Number of Years to Retirement | Years | 1 – 50 |
| i | Inflation Rate | Percentage (%) | 2% – 4% |
