Add Business Days Calculator
Find the exact future date by adding a number of working days to any start date. Ideal for setting deadlines, delivery windows, and payment due dates.
Add Business Days
Formula
End Date = Start Date + N weekdays (skip Saturday & Sunday)
Starting from the chosen date, the calculator advances one day at a time, counting only Monday to Friday until N working days have been added. The start date itself is not counted as day 1.
Worked Example
Scenario: An invoice is issued on Wednesday 1 October. Payment terms are Net 14 business days.
Start: Wednesday 1 Oct • Days to add: 14
Counting forward 14 weekdays skips two weekends (Sat 4/5 and Sat 11/12 Oct).
Result: Tuesday 21 October — that is the payment due date.
Common Mistakes
- Treating the start date as day 1. It is day 0. The first business day counted is the next weekday after your start date.
- Mixing up business days and calendar days. Net 30 calendar days is faster than Net 30 business days (which equals roughly 6 weeks).
- Not accounting for bank holidays. This tool skips weekends only. A result landing on a public holiday may not be a valid working day.
