About Delivery Date Estimate Calculator

Delivery estimates chain two working-day periods: handling before dispatch and transit afterwards. An order placed 11 May 2026 with one day handling and four days transit ships on the 12th and arrives on the 18th - seven calendar days including the intervening weekend, which is what the customer actually experiences.

Formulas

Ship date

ship = order date + handling working days

Delivery

delivery = ship date + transit working days

Assumptions and limits

The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
Figures are rounded for display to whole numbers, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

Why do couriers quote working days?

Because most services do not operate a full weekend schedule. A Friday dispatch with two day transit arrives Tuesday, not Sunday.

Should handling be counted separately?

Yes. Combining them hides the fact that an order placed late on Friday does not begin handling until Monday.
