How to Use This Tool
Enter your initial retirement savings, expected monthly withdrawal amount, projected annual return, and inflation rate. Select your preferred withdrawal method—fixed amount for nominal dollars or inflation-adjusted for real purchasing power. Click Calculate to see how long your savings will last and a detailed breakdown of the results.
Formula and Logic
This calculator uses a monthly compounding model to project your retirement balance over time. For each month, it applies the investment return to the current balance, subtracts the withdrawal amount, and adjusts for inflation if using the inflation-adjusted method. The process repeats until the balance reaches zero or a maximum period is reached.
Practical Notes
- Interest rate effects: Higher expected returns extend the duration of your savings, but also increase risk. Consider a conservative estimate for planning.
- Compounding frequency: This tool uses monthly compounding, which is standard for personal finance planning.
- Tax implications: Withdrawals may be subject to taxes; this calculator does not account for taxes. Consult a tax advisor for personalized advice.
- Budgeting habits: Regularly review and adjust your withdrawal strategy based on actual spending and market conditions.
