What is an installment plan?

From traditional loans to store financing, there are all kinds of alternative ways to pay for a large purchase. One option that’s been increasing in popularity is the installment plan structure.

With an installment plan like these, you’ll pay off your purchase in fixed, typically equal amounts over a set repayment period. Some services limit you to one repayment term – such as four payments over six weeks with Afterpay – while others allow users to pick the term that works best for them. For example, Pay It Plan it allows eligible users to choose between three different repayment periods designed to offer options for every budget.

While some installment plans charge a set interest rate, most are designed to side-step interest with a small fixed fee. Whether this fee falls on the consumer or the merchant varies by payment program.

Choosing the best service for you

So how do you navigate these online payment solutions and decide which is best for you?

This is not true in all cases, however. QuadPay and Klarna allow users to take advantage of the payment plan with any retailers by using a virtual card number. Additionally, Affirm offers a virtual card to select users.

Tips for maximizing installment plan services

Once you sign up for installment plan financing, keep these best practices in mind to get the most out of the payment solution.

  • Don’t take on too many plans at once. Smaller payments can mask how much you are actually spending, and you don’t want to be stuck with more than you can pay back.
  • Know your terms and conditions. Before you accept an offer, be sure you understand any penalties (such as account closure or late fees) that come from not meeting the set terms.
  • Always make payments on time, as late fees can be steep. Plus, some services report to credit bureaus.
  • Calculate your interest and fees to make sure you are actually saving money over another payment method. You actually might save by using a credit card – especially one with an intro APR.
  • Make your installment payments with a credit card if the service allows it, so you can still earn rewards. Plus, you’ll add a bit more flexibility to your payments this way.
  • Keep your own payment calendar, even if you have automatic payments or notifications set up. You don’t want to miss a payment if something goes wrong.

Final thoughts

Installment plan services can be a great way to finance large purchases for a low cost. Just be sure you are using the service with interest, fees and repayment terms that align with your spending habits. While it can be tempting to jump at an offer to pay over time, you should ensure it is actually a good deal before you commit.
