Formula, standards and limitations

For a loan with principal P, monthly rate r and n payments, EMI = Pr / (1 − (1+r)^(-n)). When r is zero, EMI = P/n. Compound value is P(1 + annual rate/n)^(n×years). These are mathematical illustrations, not quotes. They exclude fees, taxes, changing rates, insurance and irregular payments.
