What this calculator does
Buy-now-pay-later apps split purchases into small payments. This calculator adds them up so you see the total monthly commitment and spending.
The math
Total monthly BNPL = sum of all entered payments. Total purchase cost = sum of all entered item costs.
Worked example
Three payments of $45, $60, and $80 add up to $185 in purchases and a $185 monthly commitment if they all hit this month.
Why this matters
Saving and investing work best when the timeline is concrete. This calculator replaces vague goals with a date, a contribution, or a target you can automate.
Methodology and transparency
This page publishes the exact formula used to compute the result, so you can verify it in a spreadsheet or check the assumptions against your own situation. The worked example uses the tool default inputs; change any number and the result updates live in your browser. No data is sent or stored.
Common questions
Is BNPL debt?
Yes. It is a short-term installment obligation. Missing payments can hurt your credit and trigger fees.
Why do small payments feel invisible?
Because each one is small, but several together can consume a large chunk of your monthly budget.
How do I stop the BNPL drain?
Pause new purchases, pay off existing plans, and track the total monthly commitment in your budget.
