As there is no interest added to Afterpay payments, there is no additional cost. You will pay your instalments directly to Afterpay in accordance with the payment schedule Afterpay will send to you via email.
If a payment is due but not received by Afterpay in accordance with their payment schedule, a $10 late payment fee will be charged, with a further $7 late payment fee added seven days later if the payment remains unpaid.
In addition, because your Afterpay account is linked to your credit or debit card, standard card fees and charges may be applicable. You can refer to your card issuer’s terms and conditions for full details of their fees and charges.
