An installment loan is a loan you pay back in installments. Pretty simple, right?

OK, there's a bit more to it than that, but installment loans are a fundamental form of borrowing that most people will use in their lifetime. You get one any time you buy a big-ticket item or service and pay it off on a regular basis over a set period of time. You might be using one right now.

Here's how installment loans work, what makes them different from other loans and why you might want one.

How installment loans work

Don't have enough cash upfront? No problem.

Installment loans are very common. You can get them from banks, credit unions, storefront finance companies, online lenders — even the places you're buying from.

Let’s say you want to purchase a car from a dealership but don’t have enough cash to pay upfront. You can go to a bank and ask for an auto loan, or the dealership may offer to set up a loan for you. In either case, you get the car and are told to pay off the money in two years with equal payments every month. Part of your payments will be interest the lender keeps for allowing you to borrow the money.

That's an installment loan.

Unlike a payday loan, which will ask you to pay the entire balance back in one lump sum, an installment loan has smaller, regular payments. And unlike a credit card or line of credit, an installment loan gives you a single bundle of cash one time. You can't just go back for more.

Furthermore, installment loans have a set "term." It might be six months or 20 years from now, but your loan has an end date. Your payments will be high enough for you to pay off the total balance by then. If you opt for a longer term, your regular payments will be lower, but you'll end up losing more in interest over time.

Most of the time those payments will be fixed, meaning they'll stay the same for the whole term, but some types of installment loans will have "variable" interest rates than can change.

Mortgages are a type of installment loan for buying a home.

Many common types of loans fall under the installment category:

Personal loans

This is a general, multipurpose kind of loan. You can use it for anything: medical bills, consolidating debt, house repairs, whatever. Common terms are two to five years.

They're typically unsecured, so you don't have to put money down or offer up any collateral — property you would lose if you stopped paying your bill.

Student loans

You'll hear many a graduate grumble about these. Student loans are what allow people who can’t afford the high cost of tuition, supplies and living expenses to go to college or university.

Like personal loans, student loans are unsecured. However, because people need to borrow large sums long before they start earning good money, they can take a decade or more to pay off.

Auto loans

Auto loans are generally secured by the automobile itself, so you'll lose your new ride if you stop paying.

Terms can range from one to seven years, but choose a shorter schedule if you can. You’ll pay less in interest and will probably get better rates.


Mortgages allow people to buy homes and live in them while they pay off the loan over a long period, whether that's 10, 15 or 30 years. Some have adjustable interest rates that shift over time with the prime rate.

Home loans are also secured, so if you fail to make your payments, you risk foreclosure.

When to use an installment loan

Installment loans are great, but sometimes a line of credit might be a better option.

Installment loans are common for a reason. They have a lot of beneficial features:

  • You get to pay back the loan over time, not all at once.

  • Set terms force you to pay off the loan in good time.

  • Most have fixed payments, so you'll always know how much you owe and can budget around them.

That said, other types of loans exist for a reason. Here are a few drawbacks to consider:

  • Unlike a credit card or line of credit, you can't simply borrow more money if you need it. You'd need to apply for a new loan.

  • The payments aren't flexible. With a credit card, you can drop down to the minimum payment for a few months if you need to.

  • Some lenders charge origination fees for starting a loan or penalize you for trying to pay your debt faster than agreed.

How to get an installment loan

Know your credit score before you apply for a loan.

Before you apply for a loan of any kind, you'll want to check your credit score for free online. Those three digits tell lenders how trustworthy you are, helping them decide how much interest to charge you — and whether to approve your loan at all.

You can get a loan with bad credit or even no history of credit at all, but it's best to boost your score if you can.

Then you'll need to find a lender. You'll have a ton of options, depending on whether you're looking for a mortgage, auto loan or another kind of installment loan.

Remember to compare not just the interest rate you'll be charged but also any fees and your options for the payment schedule. Fiona is a handy website that will let you quickly compare rates from multiple lenders at once, with no hidden fees. You can borrow as little as $1,000 or as much as $100,000.

After that, you've got nothing to worry about besides making your payments. With an installment loan, your path foward is already mapped out. You just need to follow it.
