1. What is Simple Interest Finance Cost?

Simple interest finance cost is calculated using the basic formula where interest is computed only on the principal amount. It provides a straightforward method for determining borrowing costs over a specific period.

2. How Does the Calculator Work?

The calculator uses the simple interest formula:

Where:

• \( Principal \) — Initial amount borrowed or invested (dollars)
• \( Rate \) — Interest rate as a decimal fraction
• \( Time \) — Duration in years

Explanation: The formula calculates the total interest cost by multiplying the principal amount by the interest rate and the time period.

3. Importance of Finance Cost Calculation

Details: Calculating finance costs helps borrowers understand the true cost of loans, compare different financing options, and make informed financial decisions.
