What is iROAS Marketing?

iROAS, or Incremental Return on Ad Spend, is a powerful metric that measures the additional revenue generated by your advertising campaigns, beyond what would have occurred without your marketing efforts. It differs from traditional ROAS by focusing solely on the incremental revenue that your ads drive, helping you understand the true impact of your marketing spend.

While traditional ROAS provides a broad view of how much revenue is generated per dollar spent on advertising, it does not distinguish between revenue that would have occurred organically and revenue that was directly driven by the campaign. iROAS isolates this effect, allowing marketers to focus their budgets on activities that generate new and incremental growth, rather than merely capturing demand that already exists.

At Rockerbox, iROAS is an integral part of our unified measurement approach. By integrating iROAS with other tools such as Marketing Mix Modeling (MMM) and Multi-Touch Attribution (MTA), we help brands optimize their ad spend and drive true performance. With our professional services team, you also gain expert guidance in analyzing and acting on your iROAS results to ensure continuous improvement of your marketing efforts.

Why iROAS is Critical for Marketing Efficiency

Focus on Real Revenue Drivers
iROAS provides a clearer understanding of which campaigns and channels are truly driving additional revenue. By isolating the incremental impact of your marketing, you avoid attributing success to campaigns that may not be as effective as they seem when using standard ROAS alone.
Optimize Your Budget for Maximum Impact
With iROAS, you can better allocate your marketing budget to the channels and campaigns that deliver the most incremental value. This ensures that every dollar you spend is driving real growth, rather than just maintaining existing sales.
Validate Campaign Effectiveness
iROAS helps validate which campaigns are genuinely driving performance by comparing the incremental returns of different marketing activities. It’s an essential metric for marketers looking to optimize their strategy and maximize the returns on their media investments.
Complementary to MTA and MMM
iROAS doesn’t operate in isolation. At Rockerbox, we integrate iROAS with MTA and MMM to provide a unified view of your marketing effectiveness. This ensures that your marketing strategy is informed by a complete understanding of what’s working and why.

How to Calculate iROAS

Calculating iROAS is relatively simple, but it requires careful setup to ensure accuracy. Here’s how it works:

iROAS Formula:

iROAS = (Incremental Revenue - Control Revenue) / Ad Spend

Incremental Revenue: This is the revenue that can be directly attributed to your marketing campaign, which is measured through controlled experiments such as A/B testing or geo-lift testing.
Control Revenue: The revenue generated by a control group (those not exposed to the campaign) that represents what would have happened naturally without your advertising.
Ad Spend: The total cost of running your marketing campaign.

By using this formula, marketers can calculate the actual return generated by their advertising spend, rather than overestimating its impact by including revenue that would have occurred organically.
