A quick guide

Use the number with context

The answer is only useful when you know what it includes and what it leaves out.

How to use it

  1. Enter order value using the same period and unit as the other inputs.
  2. Enter product cost using the same period and unit as the other inputs.
  3. Enter cod collection fee using the same period and unit as the other inputs.
  4. Enter forward shipping using the same period and unit as the other inputs.
  5. Enter return shipping using the same period and unit as the other inputs.
  6. Enter rto rate using the same period and unit as the other inputs.
  7. Enter return loss per rto using the same period and unit as the other inputs.
  8. Enter cash-cycle cost using the same period and unit as the other inputs.

Formula

Expected RTO cost = RTO rate × (return shipping + return loss); expected contribution subtracts all costs.

The expected cost spreads RTO risk across orders; it is not a promise of actual carrier performance.

Make it concrete

Worked example

An 8% RTO rate applies 8% of return shipping plus return loss to each expected order.

Boundaries
