From: | To: |
The personal loan monthly payment formula calculates the fixed monthly payment required to repay a loan over a specified term. This formula accounts for both principal and interest payments, ensuring the loan is fully amortized by the end of the term.
The calculator uses the standard loan payment formula:
Where:
Explanation: The formula calculates the fixed payment that covers both interest and principal each month, with more going toward interest early in the loan and more toward principal later.
Details: Understanding your monthly payment helps with budgeting and financial planning. It allows you to compare loan offers and choose terms that fit your financial situation.
Tips: Enter the loan amount in USD, annual interest rate as a percentage (e.g., 5.25), and loan term in years. All values must be positive numbers.
Q1: What's the difference between interest rate and APR?
A: The interest rate is the cost of borrowing the principal, while APR includes interest plus other loan fees, giving a more complete cost picture.
Q2: How can I reduce my total interest paid?
A: You can reduce total interest by choosing a shorter loan term, making extra payments, or securing a lower interest rate.
Q3: Why does my payment stay the same but interest/principal amounts change?
A: This is called amortization - early payments have more interest because the outstanding balance is higher. As you pay down principal, less goes to interest.
Q4: Are there loans with different payment structures?
A: Yes, some loans have interest-only periods or balloon payments. This calculator assumes fully amortizing fixed payments.
Q5: How does compounding frequency affect payments?
A: Most personal loans use monthly compounding. The calculator automatically accounts for this by converting annual rate to monthly.
