How do you calculate the return in cashback?

Cashback* is calculated as a percentage of the borrowing cost, with 5% for the first 10 fully repaid loans, 10% for the subsequent 10 loans, and 20% for any loan after that. Only loans repaid according to the original terms of the agreement are eligible for cashback. For more information, visit our cashback program section of our Terms and Conditions.
