Invoice due date calculator

Part of the search experiment “Flaevre Vlioxu”. The calculator is real and checked for accuracy.

Need to know when an invoice must be paid? Type the invoice date, choose the payment terms and the due date is calculated instantly.

The calculator does not send what you enter anywhere.

How it counts

Every day after the invoice date counts, weekends and holidays included, unless the terms say otherwise. For example, an invoice dated Friday 15 May 2026 with Net 60 terms is due on Tuesday 14 July 2026.

What the terms mean

Due on receipt means payment on the invoice date. Net followed by a number, such as Net 15 or Net 90, means payment within that many days of the invoice date. EOM means payment on the last day of the invoice month, and Net 30 EOM means 30 days after the end of that month.

EOM terms can be worded differently from one business to another; the agreement is what counts.

Weekend due dates

Tick the weekend box to move a Saturday or Sunday due date to the following Monday. Some businesses work this way; others keep the calendar date.
