Frequently Asked Questions

What does "2/10 Net 30" mean?
This means the buyer receives a 2% discount if they pay within 10 days of the invoice date. Otherwise, the full amount is due within 30 days. It's one of the most common payment terms in business-to-business transactions.
When does the payment period start?
The payment period typically begins on the invoice date, not the date the invoice is received. This calculator uses the invoice date you enter as the starting point for all calculations.
Should I always take the early payment discount?
In most cases, yes. A 2/10 Net 30 discount equates to approximately 36% annual return, which is typically better than any alternative use of that cash. However, consider your own cash flow needs and whether you have the available funds.
What if the due date falls on a weekend or holiday?
Business convention typically extends payment to the next business day, but this should be clarified in your payment agreement. The calculator shows calendar dates without business day adjustments.
How is the annual rate equivalent calculated?
The calculator determines how many discount periods exist in a year, then compounds the discount percentage. For 2/10 Net 30, you're earning 2% in 20 days (30 - 10), which happens roughly 18 times per year, resulting in approximately 36% annual equivalent.
Can I customize payment terms beyond the presets?
Yes, click the "Custom" button and enter any discount percentage, discount period, and net payment days that match your business needs or supplier terms.
