Frequently asked questions
How is DPO calculated?
Average payables divided by annual cost of goods sold, times 365. It measures how long you take to pay suppliers.
Should I always take the longest terms?
Not if there is an early payment discount. Extending terms is valuable, but a 2% discount for paying twenty days early beats almost any use of the same money.
How do I calculate the value of a discount?
The discount divided by one minus the discount, times 365 over the days saved. A 2/10 net 30 discount works out at roughly 37% annualised.
Is stretching payables free?
No — it costs supplier goodwill, and eventually priority when stock is short. Agreed longer terms are valuable; unilateral late payment is expensive in ways that do not appear on any statement.
