1. What is the Loan Payment Formula?

The loan payment formula calculates the fixed monthly payment required to repay a loan over a specified term, including interest. It's based on the time value of money principle.

2. How Does the Calculator Work?

The calculator uses the standard loan payment formula:

\[ PMT = P \times \frac{r \times (1 + r)^n}{(1 + r)^n - 1} \]

Where:

\( P \) — Principal loan amount (USD)
\( r \) — Monthly interest rate (annual rate ÷ 12)
\( n \) — Total number of payments (term in years × 12)
\( PMT \) — Monthly payment amount (USD)

Explanation: The formula accounts for both principal repayment and interest charges over the loan term.

3. Importance of Loan Calculation

Details: Understanding your monthly payment helps with budgeting and financial planning. It shows the true cost of borrowing and helps compare different loan options.

4. Using the Calculator

Tips: Enter the principal amount in USD, annual interest rate as a percentage, and loan term in years. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Does this include loan fees?
A: No, this calculates only principal and interest payments. Additional fees would increase your total cost.

Q2: What's the difference between APR and interest rate?
A: APR includes fees and other loan costs, while the interest rate is just the cost of borrowing the principal.

Q3: How can I pay less interest?
A: Choose a shorter loan term or make extra payments to reduce principal faster.

Q4: Are student loans calculated differently?
A: The basic formula is the same, but some student loans have grace periods or income-based repayment options.

Q5: What if I make extra payments?
A: Extra payments reduce principal faster, saving interest and potentially shortening your loan term.
