1. What is the Fisher Equation?

The Fisher Equation describes the relationship between nominal interest rates, real interest rates, and inflation. It's a fundamental concept in economics and finance that helps determine the real return on investments after accounting for inflation.

2. How Does the Calculator Work?

The calculator uses the Fisher Equation:

Where:

• Nominal Rate — The stated interest rate (before inflation)
• Inflation Rate — The rate of price increase in the economy
• Real Rate — The actual purchasing power of your return

Explanation: The equation adjusts the nominal rate by removing the inflation component to reveal the true rate of return.

3. Importance of Real Rate Calculation

Details: Calculating the real interest rate is essential for investment decisions, economic analysis, and understanding the true cost of borrowing or return on savings.

4. Using the Calculator

Tips: Enter both rates as percentages (e.g., for 5%, enter 5). The inflation rate should be positive (negative inflation/deflation requires special consideration).

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between nominal and real rates?
A: Nominal rates don't account for inflation, while real rates show your actual purchasing power after inflation.

Q2: Can the real rate be negative?
A: Yes, when inflation exceeds the nominal rate, your purchasing power decreases.

Q3: Why divide by (1 + inflation) instead of just subtracting?
A: The division accounts for the compounding effect of inflation over time.

Q4: How often should I calculate real rates?
A: Regularly, especially when making long-term financial decisions or during periods of high inflation.

Q5: Does this work for deflation?
A: Yes, but enter the inflation rate as negative for deflation scenarios.
