1. What is the Sustainable Withdrawal Rate?

The Sustainable Withdrawal Rate is the percentage of retirement savings that can be withdrawn each year without running out of money during one's remaining lifetime. This calculator specifically helps individuals aged 70+ determine an appropriate withdrawal rate.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• Remaining Life Expectancy — Estimated years of remaining life
• Adjustment — Additional percentage (as decimal) to account for inflation or other factors

Explanation: The equation provides a baseline withdrawal rate that adjusts for longevity risk, with an optional factor for additional needs.

3. Importance of Withdrawal Rate Calculation

Details: Calculating an appropriate withdrawal rate is crucial for retirement planning to ensure savings last throughout retirement while maintaining desired lifestyle.

4. Using the Calculator

Tips: Enter remaining life expectancy in years (use actuarial tables if unsure) and any desired adjustment factor (typically 0-0.01). All values must be valid (life expectancy > 0).

5. Frequently Asked Questions (FAQ)

Q1: Why focus on age 70+?
A: This calculator is optimized for traditional retirement ages when most people begin systematic withdrawals from retirement accounts.

Q2: How do I estimate remaining life expectancy?

Q3: What's a typical adjustment factor?
A: Common adjustments range from 0 (pure life expectancy method) to 0.01 (1%) to account for inflation or desired spending increases.

Q4: Are there limitations to this approach?
A: This is a simplified model that doesn't account for investment returns, variable spending needs, or unexpected expenses.

Q5: Should I adjust my withdrawal rate over time?
