Invoice Discount & Net Calculator
Stack trade and cash discounts, apply tax correctly and reveal the effective annualized cost of an early-payment discount.
Formula
2/10 net 30 looks trivial but annualizes to ~37% — passing it up is one of the most expensive forms of trade credit. Unless your cost of capital exceeds that, always take early-payment discounts (borrow if needed). The annualized-cost view turns AP terms into an investment decision.
