Return Rate Calculator

Divide returned units by units sold to get the return rate that drives reverse-logistics cost.

About Return Rate Calculator

The return rate is the share of units sold that units returned represents, expressed as a percentage. The same figure is also shown per 1,000 and as a "one in every N" odds statement, which is easier to reason about when the rate is very small. Absolute counts hide scale — a rate normalises the number so you can compare periods, channels or cohorts of different sizes, where lower is better.

Formula

Return Rate

Return Rate = Units returned ÷ Units sold × 100

Units returned: The subset being measured
Units sold: The full population it is drawn from

Assumptions and limits

The result is derived only from the 2 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 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
This is an estimate for general information and not professional financial, tax or legal advice. See the full disclaimer for the limits that apply to this kind of calculator.

Frequently Asked Questions

How is Return Rate calculated?

Return Rate = Units returned ÷ Units sold × 100 The return rate is the share of units sold that units returned represents, expressed as a percentage. The same figure is also shown per 1,000 and as a "one in every N" odds statement, which is easier to reason about when the rate is very small.

Why does Return Rate matter?

Absolute counts hide scale — a rate normalises the number so you can compare periods, channels or cohorts of different sizes, where lower is better.

What values do I need to enter?

This calculator takes 2 inputs: Units returned, Units sold. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
