Estimate nominal annualized monthly loan cash-flow cost from a fixed interest rate, whole-month term and upfront fees. Show known results and explain numerical limits.
APR estimate for one loan advance and equal month-end payments at a fixed nominal rate. Upfront financing fees are paid or deducted at the start, not added to the loan principal; net amount received = loan amount − fees. APR = monthly cash-flow rate × 12 × 100, not effective annual yield (APY). No irregular dates, financed fees, changing rates or legal classification of fees are modeled. Compare with lender disclosures; this is not a certified regulatory APR.
