How this works and common questions

About this tool

Pick a start date and a number of calendar days. Net 15, net 30 and net 45 fill the days for you. You can type a different number.

How it works

The due date is the start date plus the number of days you enter. The count uses calendar days, including weekends. The day names come from that date. The tool does not move a weekend date.

Rules

Days can be 0 through 3650. Zero means the same day. The date is a calendar date with no time zone shift. This page does not state a late fee, a grace period, or what a contract requires.

Questions

What does net 30 mean?

The invoice is due 30 days after the start date. Net 15 or net 45 work the same way.

Does it count weekends?

It counts calendar days. If the date lands on a weekend, move it to the next business day yourself.

Can I count from a different start date?

Yes. Pick the date you count from, such as the delivery date, then enter the number of days.

Do I need an account?

No. The tools work without one. You only need to sign in to save your work.

Is what I type saved?

No. Nothing is saved unless you sign in and choose Save. Otherwise it stays on the page.

Do you show ads or sell my information?

No. We show no ads and we do not sell your information.

Is this tax or legal advice?

No. Results are estimates for planning. Check rates and rules with the official source or a qualified professional.
