Loan Calculator computes monthly payments, total interest, and amortization schedules for fixed-rate and adjustable-rate loans using standard financial formulas. It applies the annuity formula P = r*PV / (1 - (1+r)^-n) for fixed-rate loans and supports rate adjustment intervals for ARMs. The tool generates a full amortization table showing principal and interest breakdown per payment, remaining balance, and cumulative interest paid at each point in the loan term.
