1. What is Sustainable Withdrawal Rate?

Sustainable Withdrawal Rate (SWR) is the percentage of a retirement portfolio that can be withdrawn each year without depleting the principal over a specified time period, typically 30 years.

2. How Does the Calculator Work?

The calculator uses the sustainable withdrawal formula:

Where:

• \( Balance \) — Total investment portfolio value (currency)
• \( SWR \) — Sustainable withdrawal rate (decimal)

Explanation: This calculation determines the annual withdrawal amount that can be sustained from an investment portfolio based on the specified withdrawal rate.

3. Importance of Sustainable Withdrawal Calculation

Details: Proper withdrawal rate planning is crucial for retirement planning to ensure that retirement savings last throughout retirement while maintaining the desired standard of living.

4. Using the Calculator

Tips: Enter your total portfolio balance in currency and the desired sustainable withdrawal rate as a decimal (e.g., 0.04 for 4%). Both values must be positive numbers.

Q3: Should withdrawal rates change with age?
