Loan Interest Calculator
Calculate total interest paid on a loan.
Understanding Simple Loan Interest
When you take out a personal loan or borrow money, you are usually charged a fee for the privilege of accessing those funds. This fee is called interest. Calculating exactly how much total interest you will pay is the first step in responsible financial planning.
This tool handles a fundamental **Simple Interest** calculation. The formula is `Interest = Principal × Rate × Time`. It allows you to quickly figure out how much a loan will actually cost you over its entire lifespan. If you borrow $10,000 at a 5% simple annual rate for 3 years, you owe exactly $1,500 in pure interest.
By playing with the numbers, you can visibly see how extending a loan from 3 years to 5 years dramatically inflates the total amount paid back to the bank, even if the monthly rate looks appealing.
Frequently Asked Questions
What is the difference between Simple and Compound Interest?
Simple interest calculates costs purely based on the initial borrowed principal. Compound interest calculates costs on the principal PLUS all previously accumulated interest. Mortgages typically use a compound calculation.
Can I use this for credit cards?
Credit cards do not use simple interest—they use daily compounding interest. This calculator is best for flat personal loans or family loans.
