Cost of BNPL Defaults Calculator NZ

This calculator shows the real cost of missing Buy Now Pay Later payments in New Zealand, adding up the late fees on services like Afterpay, Laybuy and Zip and turning them into a clear surcharge on your purchase. Buy Now Pay Later is marketed as interest free, and it is when you pay on time, but the moment an instalment is missed the late fees begin, and because they are charged on small purchases they can become a surprisingly large percentage of what you bought. A few dollars in fees on a fifty dollar order can work out to a surcharge of twenty, thirty or even forty percent, far more than ordinary credit would cost over the same short window. You enter the order value, the late fee your provider charges per missed instalment and how many payments you missed, and the calculator totals the fees, applies a typical cap of the lesser of twenty five percent of the order or a fixed dollar amount, and shows the effective surcharge as a percentage. Seeing it as a percentage is the point, because it reframes a handful of dollars as the expensive credit it really is. Use it to understand the true cost before relying on BNPL, and check your provider's current fees and cap, as they change.

Cap is the lesser of your entered dollar cap or 25% of the order value, as most NZ providers apply. Check your provider's current fees. Estimate only.

How it works

The calculator multiplies the late fee by the number of missed payments to get the raw fees, then caps the total at the lesser of your dollar cap or 25 percent of the order value, which is how most providers limit fees. The effective surcharge is the capped fees divided by the order value, and the total you repay is the order plus those fees.

Worked example

On a 200 dollar order with a 10 dollar late fee and 3 missed payments, the raw fees are 30 dollars. The cap is the lesser of 68 dollars or 50 dollars (25 percent of 200), so 50 dollars; 30 is under that, so you pay 30 dollars in fees, a 15 percent surcharge, and repay 230 dollars.

Frequently asked questions

How much are BNPL late fees in New Zealand?

It varies by provider. Afterpay charges an initial late fee and a further fee if still unpaid, capped at the lesser of 25 percent of the order or a set dollar amount. Laybuy and Zip have their own fees. Enter your provider's fees to see the total.

Is there a cap on BNPL late fees?

Most providers cap total late fees on a single order, often at 25 percent of the purchase price or a fixed dollar amount, whichever is lower. The calculator applies a cap so you see the most you could be charged.

Why are missed BNPL payments expensive?

Because the fees are a large share of a small purchase. A few dollars of late fees on a 50 dollar order can be a 20 to 40 percent surcharge, far higher than typical credit interest over the same short period.
