Loan Calculator

What is a loan calculator?

A loan calculator helps you estimate the costs when taking out a loan. You get details about monthly payments, total interest charges, and the overall cost of the loan.

Inputting variables like the loan amount, interest rate, and loan term (the length of time to repay the loan) lets you quickly calculate:

• How much you’ll need to pay each month

• How much you’ll repay in total over the life of the loan

Key inputs:

• Loan amount - The total amount of money you borrow

• Interest rate - The percentage charged by the lender for borrowing the money

• Loan term - The duration of the loan, typically in months or years

• Down payment (optional) - The initial amount you pay upfront to reduce the total loan amount

• Additional Fees (optional) - Some calculators may allow you to input extra fees, such as insurance costs for home loans

Key outputs:

• Monthly payment - The amount you'll pay monthly, including the principal and interest

• Total interest paid - The total amount of interest you’ll pay over the life of the loan

• Total loan amount - The final amount you’ll repay, including the loan principal and the interest charges

• Amortization schedule - Some calculators have an amortization schedule (how much of each monthly payment goes toward the principal and how much goes toward interest over time)
