A "net 30" invoice is due 30 days after its date, so this is a quick way to check a payment deadline.
Frequently asked questions
Is 30 days the same as a month?
Not exactly. Thirty days is a fixed count, while a calendar month runs from 28 to 31 days depending on which one it is.
What does net 30 mean?
A net 30 invoice is payable 30 days from its date; enter the invoice date to find the due day.
Can I count 30 days from a past date?
Yes. Change the start date to any day and the tool adds 30 days from it.
