What Is a Loan Calculator

A loan calculator estimates your monthly payment based on the loan amount, interest rate, and term. It's commonly used for mortgages, auto loans, and personal loans to understand borrowing costs before committing.

How to Calculate Loan Payments

Monthly loan payments are calculated using the amortization formula. The payment depends on three factors: the principal amount borrowed, the annual interest rate, and the loan term. This calculator shows you the monthly payment, total interest, and provides a complete amortization schedule.

How Loan Term Affects Your Payment

The loan term significantly impacts both your monthly payment and total cost. A longer term (like 30 years) means lower monthly payments but more interest paid over time. A shorter term (like 15 years) means higher monthly payments but less total interest. Use this calculator to compare different scenarios.

Frequently Asked Questions

How is monthly payment calculated?
Monthly payments use the standard amortization formula: M = P × [r(1+r)^n] / [(1+r)^n-1], where P is the principal, r is the monthly interest rate, and n is the number of payments.
What's the difference between APR and interest rate?
The interest rate is the cost of borrowing the principal. APR (Annual Percentage Rate) includes the interest rate plus other costs like fees and mortgage insurance.
How does loan term affect total cost?
Longer loan terms mean lower monthly payments but higher total interest paid. A 30-year mortgage will cost more in interest than a 15-year mortgage.
