Cuota fija vs sobre saldos: que metodo de credito necesita tu cooperativa

If you manage a savings and credit cooperative, one of the most important decisions is how to calculate loan interest. The two most common methods are flat rate and declining balance. Choosing wrong can affect your cooperative's competitiveness and member satisfaction.

Flat rate (fixed installment)

Interest is calculated on the original loan amount throughout the entire credit life. The monthly payment is always the same.

Declining balance

Interest is calculated on the outstanding balance. As the member pays principal, interest decreases.

Which to choose

The ideal approach is to offer both methods and let the member choose based on their payment capacity.

A system like RAILCOOP automatically calculates both methods, generates payment plans, controls delinquency, and reports to regulators. No spreadsheets, no manual errors.
