Business days = weekends excluded. Federal holidays are not excluded.

What Is Net 45?

Net 45 means the full invoice amount is due 45 days after the start date on the invoice. As with Net 30, the start date can be the invoice date, the delivery date, or the end of the invoice month (EOM 45) — check which basis your contract or purchase order specifies. Net 45 terms are a middle ground between Net 30 and Net 60, common once a trade-credit relationship is established.

How a Net 45 Due Date Is Calculated

Due date = start date + 45 calendar days (or 45 business days if your agreement excludes weekends). Enter the invoice date above and pick your start-date basis for the exact due date. For an early-payment discount such as 2/10 Net 45, use the main calculator, which adds a discount deadline and savings figure.
