There is no minimum repayment amount nor installment payments. You can make repayments at any time. Interest is charged daily on the outstanding balance and is debited from your available loan limit.
We plan to introduce Installment Loans in Q2 2019, according to our current Roadmap.
Please note that if you repay a loan within 30 days of the last withdrawal, you will be charged interest for the full 30 days. Repayments will be used to cover the earliest loan withdrawals and to pay off interest before the principal.
