What "Net 30" means
Net terms set how long a customer has to pay after the invoice date. Net 30 means the full amount is due 30 days later, Net 60 is 60 days, and so on. Enter the number of days and the calculator adds them to the invoice date to find the due date.
Calendar days or business days
Most net terms count calendar days — weekends included. Some contracts count business days (Monday to Friday) instead, which pushes the date later. Pick the one your agreement uses; the gap grows with longer terms.
Weekends, holidays and late fees
The calculator shows the day of the week so you can spot a due date that lands on a weekend — many businesses accept the next business day in that case. It does not skip public holidays, which vary by country and state, so check those. Knowing the exact due date helps you avoid late fees and plan cash flow.
