Check for hidden fees and interest before signing up

Read the terms carefully. Many BNPL services charge zero interest if you pay on time, but late fees of $5-$25 per missed payment and deferred interest of 25-36% APR if you miss the window. Some longer-term plans charge interest from day one.

Why It Works

Knowing the true cost lets you make an informed comparison. A "4 easy payments" plan that charges a $7 late fee on one missed payment costs more than putting it on a credit card you pay off quickly.

Tips

• Afterpay and Klarna short-term plans (pay in 4) are typically interest-free but charge late fees
• Affirm longer-term plans often charge 0-36% APR depending on credit
• Always check if there is a discount for paying in full — some retailers offer 5-10% off for upfront payment
