How does a personal loan work?

Quick answer

You get the loan money once, then pay it back over a set time. Each payment pays interest and part of what you owe. The loan does not refill as you pay it down. Before you sign, check the amount, rate, loan length, and fees.

First, check the money you receive

The loan amount is what you borrow before fees. A lender may take a fee from that amount before sending the cash. For example, a $500 fee taken from a $10,000 loan leaves $9,500 to use.

That fee does not reduce what you owe. If the cash is too low to cover your expense, compare another offer before you borrow more.

Then, check how the payments work

The interest rate is the price charged for borrowing the money. The loan length, often called the term, is the number of months you have to pay it back.

With a fixed rate, the monthly payment usually stays the same. More months can lower that payment, but you may pay more interest in all. If the rate can change, ask how that affects the payment.

The payment stays due until the loan is paid

You still owe the money if the item you bought breaks or your plans change. A missed payment can add fees and hurt your credit. Ask the lender about help as soon as you think you may miss one.

Check the full cost before you sign

Make sure the cash covers the expense and the payment fits beside your bills. Then add up what you will pay over the whole loan. A clear end date helps you plan, but it does not make a loan cheap.

Count what you will pay in all

Now that you know how the payments work, see how interest and fees add to the price.
