Return on Ad Spend (ROAS) measures how much revenue you generate for each dollar of advertising spend. It is a primary paid-media efficiency metric — complementary to ROI, which subtracts cost first.

• Budget allocation

  Shows which campaigns deserve more spend.

• Creative & audience tests

  A clear efficiency readout for experiments.

• Target setting

  Pairs with contribution margin to set break-even floors.

• Stakeholder reporting

  Communicates paid performance simply.

• Scale decisions

  Rising spend with falling ROAS is a warning.

1. 01

   Attribution model

   Last-click vs data-driven changes reported ROAS.

2. 02

   Offer & landing page

   Weak conversion caps return even with cheap clicks.

3. 03

   Audience quality

   Broad targeting can inflate spend without revenue.

4. 04

   Creative fatigue

   Decaying ads reduce efficiency over time.

5. 05

   Seasonality

   Demand swings move ROAS independent of media quality.

6. 06

   Margin structure

   High ROAS can still lose money with thin margins.

A ROAS calculator converts attributed revenue and ad spend into ROAS and ROI so media teams can evaluate campaign efficiency.

• Live efficiency

  See ROAS and ROI as inputs change.

• Campaign comparison

  Standardize math across platforms.

• Target checks

  Compare results to break-even ROAS.

• Faster reporting

  Skip spreadsheet setup for a first pass.

• Decision support

  Pause, scale, or fix campaigns with clearer evidence.

1. Step 1

   Enter revenue

   Use revenue attributed to the campaign or channel.

2. Step 2

   Enter spend

   Use media cost for the same window.

3. Step 3

   Read ROAS

   Interpret the multiple (e.g. 3.5×).

4. Step 4

   Check ROI

   Review profit percentage alongside ROAS.

A good ROAS depends on contribution margin. A 3× ROAS may be excellent for high-margin software and unprofitable for low-margin retail. Set targets from break-even ROAS, then add overhead and profit requirements.
