1. What is Post-retirement Portfolio Projection?

Post-retirement portfolio projection helps estimate how long your retirement savings will last by calculating the balance after accounting for withdrawals, investment returns, and inflation. This projection is essential for sustainable retirement planning.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• \( Initial \) — Starting balance of your retirement portfolio
• \( Annual Withdrawal \) — Amount withdrawn each year for living expenses
• \( Returns \) — Annual investment returns as a decimal (e.g., 0.05 for 5%)
• \( Inflation \) — Annual inflation rate as a decimal (e.g., 0.02 for 2%)

Explanation: This formula projects your portfolio balance after one year, accounting for withdrawals, investment growth, and the erosive effects of inflation.

3. Importance of Retirement Planning

Details: Proper retirement planning ensures financial security throughout your retirement years. Understanding how withdrawals, returns, and inflation interact helps prevent outliving your savings and maintains your desired lifestyle.

4. Using the Calculator

Tips: Enter all values in the specified units. Initial balance and annual withdrawal should be in currency units, while returns and inflation should be entered as decimals (e.g., 0.05 for 5%). All values must be non-negative.

5. Frequently Asked Questions (FAQ)

Q1: What is a safe withdrawal rate in retirement?
A: The 4% rule is commonly used, but individual circumstances vary. Consider your life expectancy, investment strategy, and inflation when determining your withdrawal rate.

Q2: How does inflation affect retirement savings?
A: Inflation reduces purchasing power over time. A 3% annual inflation rate means your money will be worth half in about 24 years, making inflation protection crucial.

Q3: What investment returns should I expect in retirement?
A: Conservative portfolios might average 3-5%, balanced portfolios 5-7%, and aggressive portfolios 7-9% annually, though past performance doesn't guarantee future results.

Q4: How often should I recalculate my retirement projection?
A: Annually, or whenever there are significant changes in market conditions, spending needs, or life circumstances.

Q5: What if my projected balance becomes negative?
A: This indicates your current strategy may not be sustainable. Consider reducing withdrawals, increasing returns through asset allocation, or exploring additional income sources.
