You can repay the loan in one of the following forms:
Annuity (equal payments).
In this case, the client makes equal monthly payments consisting of a portion of the loan and a portion of the interest.
Differentiated.
In this case, the principal is repaid each time in equal portions and the interest decreases with each payment and is accrued on the outstanding amount.
Mixed.
The client may choose an individual repayment schedule based on the seasonality of cash flows, provided that at least 20% of the contractual loan amount is repaid each year; the interest is payable on a monthly basis.
