1. What is Simple Interest Loan?

A simple interest loan calculates interest only on the principal amount throughout the loan term, without compounding. This results in predictable payments and lower total interest compared to compound interest loans.

2. How Does the Calculator Work?

The calculator uses the simple interest formulas:

\[ \text{Total Payment} = P + (P \times r \times t) \] \[ \text{Monthly Payment} = \frac{\text{Total Payment}}{t \times 12} \]

Where:

\( P \) — Principal loan amount (USD)
\( r \) — Annual interest rate (decimal)
\( t \) — Time in years

Explanation: The total payment includes the principal plus simple interest, and the monthly payment divides this total by the number of months in the loan term.

3. Importance of Payment Calculation

Details: Calculating payments accurately helps borrowers understand their financial commitments, compare loan options, and budget effectively for repayment.

4. Using the Calculator

Tips: Enter principal in USD, annual interest rate as a decimal (e.g., 5% = 0.05), and time in years. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: How is simple interest different from compound interest?
A: Simple interest calculates only on the principal, while compound interest calculates on principal plus accumulated interest, resulting in higher total interest.

Q2: What types of loans use simple interest?
A: Common examples include some personal loans, short-term loans, and auto loans. Most mortgages use compound interest.

Q3: How does loan term affect payments?
A: Shorter terms mean higher monthly payments but lower total interest. Longer terms reduce monthly payments but increase total interest.

Q4: Are there limitations to simple interest loans?
A: While simpler to calculate, they may not reflect real-world loan products that often use compound interest or have additional fees.

Q5: Can I use this for business loans?
A: Yes, if the business loan uses simple interest. Always verify the interest calculation method with your lender.
