What is return on ad spend (ROAS)?

Understand reported conversion value per ad spend and the business questions it does not answer.

THE SHORT ANSWER

ROAS divides attributed conversion value by advertising spend. A result of 3× means three units of reported value per unit of spend under the chosen measurement rules. The value definition determines whether that ratio describes revenue, estimated leads or something else.

How to read this metric

  1. Check the conversion-value source, currency and attribution settings. Match them to the spend period and account scope.

  2. Divide value by spend and label the result as a multiple or percentage consistently. Keep the underlying amounts visible.

  3. Consider costs and business outcomes outside the advertising report separately. Do not equate platform-attributed value with profit.

ILLUSTRATIVE EXAMPLE · NOT CUSTOMER DATA

Make it concrete.

An illustrative report contains 7,500 in value and 2,500 in spend, yielding 3× or 300% ROAS. Those two formats describe the same ratio.

What to keep in mind.

Spend of zero makes the ratio undefined. Summing value across providers may double-count an outcome credited by both.

Your next useful step.

Use ROAS for a clearly scoped ad-performance question. Check the actual value and cost basis before drawing a commercial conclusion.

Working with this in Liftaven

A metric needs a numerator, denominator, reporting period and source. Record those alongside the result. The examples in these notes are invented to explain the calculation; they are not industry benchmarks or Liftaven customer results.
