1. What is Interest Rate Comparison?

The Interest Rate Comparison calculator helps you compare two different loan or investment rates by calculating the percentage difference between their payments. This helps in financial decision making when choosing between different rate options.

2. How Does the Calculator Work?

The calculator uses the comparison formula:

Where:

• \( Rate1\ Payment \) — Payment amount at first interest rate
• \( Rate2\ Payment \) — Payment amount at second interest rate

Explanation: The formula calculates the percentage difference between two payment amounts, showing how much more or less one rate costs compared to the other.

3. Importance of Rate Comparison

Details: Comparing interest rates helps identify the most cost-effective option for loans or the most profitable option for investments. Even small percentage differences can lead to significant savings or earnings over time.

4. Using the Calculator

Tips: Enter both payment amounts in dollars. The calculator will show the percentage difference between them. Positive percentage means Rate1 is higher, negative means Rate1 is lower.

Q3: How does this apply to investments?
A: Higher rates typically mean higher returns, but also consider risk factors and liquidity.

Q4: Can I compare more than two rates?
