How does this tool work?
- Enter the invoice date and payment terms in days.
- Enter the actual payment date if the invoice was paid.
- See the due date and the number of days early or late.
Is the due date based on calendar days?
Yes. This calculator adds the number of calendar days you enter. It does not automatically adjust for holidays.
What if the invoice is still unpaid?
Use today as the comparison date if you want to see how many days overdue it is, or leave payment timing to your receivables report.
