FAQ
Is Afterpay really interest-free?
The instalments themselves carry no interest; the cost is late fees — $10 per missed payment plus $7 if still unpaid after 7 days, capped at the lesser of 25% of the order value or $68. Pay on time and it costs nothing extra.
How much does Zip Pay cost per month?
A $9.95 monthly account fee applies in any month you carry a balance (waived if you pay the statement closing balance in full); missing the minimum repayment adds a $7.5 late fee. The slower you repay, the more monthly fees stack up — which is exactly what this calculator shows.
