What 2/10 net 30 is really worth
Terms like 2/10 net 30 mean a 2% discount if you pay within 10 days, with the full amount due at 30. Taking it means paying 20 days early to save 2%, which annualises to roughly 37%.
That is the number to compare against your cost of money. If an overdraft or a supplier facility costs less than the annualised discount, borrowing to take the discount makes money. If it costs more, take the full term and keep the cash.
