What Net 90 means

"Net 90" means payment is due 90 calendar days after the invoice date. Weekends and holidays inside the period count toward the 90 days. The invoice date is day 0, and only the final date is usually moved if it lands on a non-business day.

Worked examples (United States holidays)

Neither date needs adjustment, but changing the invoice date by a day or two often lands on a weekend; the calculator shows when and why the date moved.

Frequently asked questions

Is Net 90 three months?

Does Net 90 count business days?

No, it counts calendar days unless the contract says business days. For a business-day term, type something like Net 90 BD in the calculator.

Public holidays for the country (and optional region) you select, from an open-source holiday dataset. You can add company holidays too.
