The returns you get each month will sometimes vary, for a number of reasons:
A borrower's first repayment will almost always be slightly larger than the rest of their repayments (because their first payment usually happens over a month after they receive their money)
Because your borrowers will have other lenders, their repayments have to be split. This may result in parts of pennies being owed to you - we keep a track of these and pay them into your account once you reach a full penny
Sometimes a borrower repays early or is late with a payment.
