Loan Calculator: Free Online Tool & Complete Guide

What is the Loan Calculator?

Before borrowing — a mortgage, a car loan, a student loan or a personal loan — you need to know what it will actually cost. The monthly payment alone is not enough: interest compounds every month, and the total interest can dwarf the amount you borrowed.

This loan calculator tells you the monthly payment, total interest and total cost of any loan, and breaks the whole term down into a month-by-month amortization schedule showing exactly how much of each payment goes to interest versus principal. Adjust the amount, rate and term and watch everything update instantly.

Frequently asked questions about the Loan Calculator

Here are the answers to the questions people ask most about the Loan Calculator.

• How is the monthly payment calculated? — Using the standard amortization formula: M = P × r / (1 − (1 + r)^−n), where P is the amount, r the monthly rate and n the number of months.
• What is an amortization schedule? — It is a month-by-month breakdown of your loan showing how much of each payment goes to interest and how much reduces the principal balance.
• Why is my total interest so high? — Interest compounds on the remaining balance each month. Longer terms mean smaller payments but much more total interest — try a shorter term to compare.
• Does the calculator include fees or taxes? — No — it computes pure principal-and-interest. Add fees, insurance or taxes separately for a full picture.
• Is this financial advice? — No — it is an informational calculator. Always confirm terms with your lender before committing.
