Delivery Radius Cost Calculator

Work out delivery radius cost instantly with clear inputs, formula shown and shareable results.

About Delivery Radius Cost Calculator

Delivery cost per order rises linearly with radius but coverage area rises with its square, so extending the radius adds disproportionate cost per order at the edge. Batching multiple orders per trip is the only lever that materially reduces the per-order figure.

Formulas

Round trip distance

Round trip = Radius x Distance multiplier x 2

Cost per order

Cost per order = Round trip distance x Cost per km / Orders per trip

Worked example

With the default values below, Delivery Radius Cost Calculator returns Delivery cost per order of $97.50. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax or compounding frequency into account.
Figures are rounded for display to 2 decimal places, 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

Should I extend the delivery radius?

Only if the incremental orders at the edge still cover their delivery cost and the longer trips do not degrade service times for closer customers.

How much does batching help?

A great deal. Moving from 1.0 to 1.8 orders per trip cuts per-order delivery cost by nearly half without any change in radius.
