FAQ

Why does the APR look high compared with a credit card?

Flat BNPL fees collected over short timelines can produce double-digit APRs when annualized. Use the output to compare against card intro offers or personal loans.

How do I include late fees?

Add expected late charges into the total BNPL fees input so the calculator reflects the true cost of missed payments.

Can I test zero-interest promos?

Yes. Enter $0 in the BNPL fee field—the APR will return 0% and the monthly payment will simply divide the purchase by the term.

Does the calculator handle biweekly plans?

Convert the term to months by multiplying the number of biweekly payments by two and dividing by four. For example, eight biweekly payments equals a four-month term.
