^Up to 110 days Interest Free on humm90 Mastercard purchases (excluding cash advances) when you meet the Interest Free Criteria. Failure to make the required payments will result in you no longer meeting the Interest Free Criteria meaning that all new transactions from that day will be interest bearing from the date of the transaction. Any outstanding balance after the Interest Free Period reverts to the humm90 Purchase Rate, currently 25.80% p.a. and subject to change. Minimum monthly repayment required.
