Personal Loan Calculator

See your monthly payment and total interest before you apply.

Educational estimate only. We are not a lender or advisor, and this is not financial or credit advice.

What it tells you

Enter how much you want to borrow, the APR and the number of months. You get the monthly payment, the total you will repay and the interest you will pay, which is the real price of the loan.

How the payment is worked out

Fixed-rate loans use the amortisation formula: payment = amount x r / (1 - (1 + r)^-n). Here r is the APR divided by 12 and n is the number of monthly payments. Total interest is payments made minus the amount borrowed.

A worked example

Borrowing $15,000 at 10.5% APR over 48 months gives a payment of about $384 a month. You would repay roughly $18,434 in total, so the loan costs about $3,434 in interest. Stretch the same loan to 60 months and the payment drops, but the interest climbs.

Using the result well

Compare the payment with your monthly budget, then compare total interest across several lenders. A slightly higher payment over a shorter term usually saves the most money.

What is not included

Origination fees, late fees and insurance add-ons change the real cost. Use the APR with fees calculator to include them.
