1. What is the Inflation-Adjusted Value?

The inflation-adjusted value shows the real purchasing power of a lump sum investment after accounting for inflation over time. It helps investors understand the true value of their money in today's dollars.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• \( principal \) — Initial investment amount
• \( rate \) — Annual rate of return (as decimal)
• \( inflation \) — Annual inflation rate (as decimal)
• \( t \) — Time period in years

Explanation: The formula calculates the future value of money considering both growth and inflation, showing the real purchasing power.

3. Importance of Inflation Adjustment

Details: Inflation erodes purchasing power over time. This calculation helps investors understand what their investment will truly be worth in terms of today's buying power.

4. Using the Calculator

Tips: Enter the principal amount, expected annual return, estimated annual inflation rate, and time period. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Why adjust for inflation?
A: Inflation reduces purchasing power over time. $100 today won't buy the same amount in 10 years. This adjustment shows the real value.

Q2: What's a good rate of return to use?
A: Historically, stock markets return about 7-10% annually before inflation. Bonds return about 3-5%. Use realistic expectations.

Q3: What inflation rate should I use?
A: Long-term average is about 2-3% in developed countries. For conservative estimates, use 3-4%.

Q4: Does this account for taxes?
A: No, this is a pre-tax calculation. For more accurate personal results, consider after-tax returns.

Q5: Can I use this for retirement planning?
A: Yes, it's useful for understanding how inflation will affect your retirement savings over time.
