Common Questions
Is 0% BNPL actually free?
+
There's no interest if paid on time — but the opportunity cost of spending that money instead of investing it is very real, as this tool shows.
When is BNPL a mistake?
+
When you use it to buy something you couldn't otherwise afford, miss a payment (fees often kick in), or use it so often the cumulative opportunity cost becomes significant.
