Net 15 Invoice Terms: Example, Due Date and Wording

Every common term for this invoice date

The rows follow the invoice date above. Tap a date to copy it; the highlighted row is the term you picked.

EOM rows start counting when the invoice month ends (method 1); the EOM guide shows the second reading. Dates are calendar arithmetic: weekends and holidays are not skipped.

Net 15 invoice example

An invoice on Net 15 terms prints the term and the date it produces. Names and amounts below are placeholders.

10 January 2026 + 15 days = 25 January 2026. For any other invoice date, use the calculator above. For a ready-made file, the Excel version of the Net 30 invoice template works out the due date from the invoice date and a Net-days cell you can change to 15.

What Net 15 means

due date = invoice date + 15 calendar days. The day after the invoice date is day 1, and day 15 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 in the payment terms guide.

Late interest in the calculator is simple interest: amount × yearly rate × days late ÷ 365, where the days late are the days after the due date up to and including today. It is arithmetic on the rate you enter, not a statement that the rate is allowed.

Net 15 due dates for 2026

An invoice dated the 15th of each month of 2026 and its Net 15 due date.

"Weekend" is only a flag: Net 15 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 15 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 15. Payment is due within 15 days of the invoice date, by [due date].
• Please pay the full amount within 15 days of the invoice date (due [due date]).
• Terms: 15 days net. Due date: [due date].

Filled in for an invoice dated 10 January 2026: "Payment terms: Net 15. Payment is due within 15 days of the invoice date, by 25 January 2026."

When a Net 15 invoice is paid late

Net 15 sets the due date; what you can charge after it depends on your contract and the law that applies. For US business invoices, the late fee calculator has a page for each state that quotes its statute (all state pages), and how to calculate late fees explains the methods. If the invoice stays unpaid, the demand letter generator drafts a formal request.
