EAR Effective Annual Rate — the real annual return including compounding, like APY on a savings account. A 2% discount paid 20 days early compounds to 36.7% per year.
2/10 Net 30 Payment terms: 2% discount if paid within 10 days, full amount due in 30 days. This is the most common early payment structure in procurement.
APR Annual Percentage Rate — the simple annual interest rate. For dynamic discounting, typical APRs range from 12% to 18%, depending on the discount and how early you pay.
DPO Days Payable Outstanding — how many days on average you take to pay suppliers. Extending DPO unilaterally hurts suppliers. Dynamic discounting lets you optimize it collaboratively.
