Net 30 Calculator: Due Date and Wording for 30-Day Payment Terms

Net 30 means the full invoice amount is due 30 calendar days after the invoice date. An invoice dated 10 January 2026 is due on 9 February 2026 (Monday). Weekends and public holidays count like any other day.

Also written as: Net 30 days · 30 days net · 30 days nett · 30 day payment terms · payment within 30 days · invoice payable within 30 days · terms of payment 30 days · 30 days to pay invoice

It starts with today's date, so the first result is Net 30 from today. Net terms on an invoice count from the invoice date unless the contract says otherwise; if your contract counts from another event, such as receipt of the invoice, delivery or completion of the work, enter that date instead.

What Net 30 means

due date = invoice date + 30 calendar days. The day after the invoice date is day 1, and day 30 is the due date: the last day to pay on time, unless the contract says otherwise.

This is date arithmetic only. Where a law sets its own payment period, it can count from a different event; the rules we have verified are quoted below.

"Weekend" is only a flag: Net 30 counts calendar days, and whether a payment due on a Saturday or Sunday may be made on the next business day is for your contract to say.

Net 30 vs 30 Days EOM

Net 30 counts from the invoice date. 30 Days EOM counts 30 days from the end of the invoice month (method 1). A second reading counts 30 days from the invoice date and then runs to the end of that month (method 2). The same invoice dates give these due dates:

Invoice dateNet 3030 Days EOM, method 130 Days EOM, method 2

Net 30 wording to copy

Replace [due date] with the date from the calculator. Printing the date, not only the term, means nobody has to count days.

  • Payment terms: Net 30. Payment is due within 30 days of the invoice date, by [due date].
  • Please pay the full amount of this invoice within 30 days of the invoice date (due [due date]).
  • Terms: 30 days net from the invoice date. Due date: [due date].
  • Payment is due 30 days after the invoice date, on [due date]. Please include the invoice number with your payment.
  • Net 30 — payment due [due date].

Filled in for an invoice dated 10 January 2026: "Payment terms: Net 30. Payment is due within 30 days of the invoice date, by 9 February 2026."

Is payment taken automatically on day 30?

No. A Net 30 invoice only states when payment is due. Money moves on day 30 only if the payer pays it, or has separately authorised you to collect it, for example by a direct debit or a recurring card or bank payment. That authorisation is an arrangement between the payer and the collector; the invoice term alone does not create it.

What the law says about 30-day payment periods

These rules set legal periods of their own, quoted word for word. Where a rule says what its period counts from, that is noted under the quote: it is not always the invoice date that "Net 30" on an invoice counts from.

Net 30 FAQ

Does Net 30 count from the invoice date or from when the invoice is received?

On an invoice, Net 30 counts from the invoice date unless your contract names a different start. Some legal default rules start elsewhere: the UK rule and EU Directive 2011/7/EU count from receipt of the invoice (or delivery in some cases), US federal agencies from receipt of a proper invoice, and California's freelance law from completion of the work when the contract sets no date. The quotes are on this page. If your contract counts from one of those events, enter that date as the start date.

Is "payment within 30 days" the same as Net 30?

Both give the customer 30 days. "Payment within 30 days" does not say on its own where the 30 days start, so add "of the invoice date" and print the due date. The wording block on this page does both.

Is Net 30 the same as 30 days EOM?

No. 30 days EOM counts 30 days from the end of the invoice month, so it is always the same as Net 30 or later. On an invoice dated 15 January 2026, Net 30 is due on 14 February 2026; 30 days EOM is due on 2 March 2026 counting from the last day of the month.

Does 2/10 Net 30 change the due date?

No. The full amount is still due 30 days after the invoice date. 2/10 adds an offer: the customer may take 2% off if it pays within 10 days. The early payment discount calculator shows what that discount is worth.

Not legal advice. The dates on this page are calendar arithmetic. Legal texts are quoted with the date we last checked them, which is not a promise that they are still current; confirm the rules that apply to your contract at the official source.
