About this calculator

The microcredit monthly interest calculator estimates the monthly interest rate for small loans, commonly used in financial inclusion programs. It works by calculating the monthly percentage based on the loan amount, term, and annual rate. Useful for comparing offers from financial institutions or understanding the real costs of low-value loans.

It uses a simplified compound interest formula adjusted for microcredit: monthly interest = (annual rate / 12) * remaining balance. Suitable for short-term loans (6-24 months) with rates from 3% to 15% per month. It can be used by social program beneficiaries or self-employed individuals seeking affordable financing.

For example, if you're evaluating a R$1,000 loan over 12 months at 5% monthly interest, the calculator shows initial interest payments will be higher, decreasing as the balance drops. Note: High rates can make the loan expensive over time, even with a low initial amount.

Warning: Microcredit doesn't include paycheck deductions like traditional consigned loans. Check for additional fees (IOF, insurance) and whether the amortization plan follows SAC or American systems. Always compare offers before signing.
