| From: | To: |
Simple interest is a method of calculating the interest charge on a loan based on the original principal amount. Unlike compound interest, simple interest doesn't accumulate on previously earned interest, making it easier to calculate and understand.
The calculator uses the simple interest formula:
Where:
Explanation: The formula calculates how much interest you'll pay over the life of a loan based on the original amount borrowed, the interest rate, and the time period.
Details: Understanding simple interest helps borrowers estimate total loan costs, compare different loan offers, and plan their repayment strategy. It's commonly used for short-term loans, car loans, and some personal loans.
Tips: Enter the principal amount in dollars, annual interest rate as a percentage, and time period in years. All values must be positive numbers.
Q1: What's the difference between simple interest and compound interest?
A: Simple interest is calculated only on the principal amount, while compound interest is calculated on the principal plus any accumulated interest.
Q2: What types of loans typically use simple interest?
A: Simple interest is commonly used for auto loans, short-term personal loans, and some mortgage products.
Q3: How does time affect simple interest calculations?
A: The longer the time period, the more interest you'll pay. Interest accumulates linearly with time in simple interest calculations.
Q4: Can I use this calculator for partial years?
A: Yes, you can enter decimal values for time (e.g., 1.5 for one and a half years).
Q5: Does this calculator account for additional payments or fees?
A: No, this calculator only computes basic simple interest. It doesn't account for additional payments, fees, or changing interest rates.
