How to Use the Retirement Money Longevity Calculator
- Enter Your Current Savings ($): Input the total amount you have saved for retirement (e.g., 500000). Must be a positive number.
- Enter Your Annual Withdrawal ($): Input how much you plan to withdraw each year (e.g., 30000). Must be greater than zero.
- Enter Expected Annual Return (%): Input the average annual return you expect on your savings (e.g., 5 for 5%). Can be zero.
- Click "Calculate": The calculator will show how many years and months your money will last.
Understanding the Result:
- If your annual withdrawal is less than or equal to the expected return on your savings (withdrawal ≤ savings × return rate), the result will show "Indefinitely" — your money never runs out.
- Otherwise, the result displays the number of years and months your savings will last based on the annuity formula.
Important Note: All monetary values must be in US dollars ($). The return rate is a percentage (e.g., 5 for 5%). Ensure all inputs are positive numbers where applicable.
