Marketing ROI: definition, formula, and dashboard example

Marketing ROI tells you how much revenue your ad spend actually generates, not how many clicks it bought. Here is how to calculate it, what distorts the number, and how home-service operators track it live.

Formula

Marketing ROI = (revenue attributed to marketing − marketing spend) ÷ marketing spend × 100

Subtract total marketing spend from the revenue those campaigns generated, divide by the spend, and multiply by 100 to get a percentage return. A result of 200% means every dollar spent returned three dollars: your original dollar back plus two more.

For ad-platform metrics, see cost per booked job and ROAS. Those are spend-efficiency ratios, not the same as marketing ROI, which nets out the full cost.

What is marketing ROI?

Marketing ROI measures how much revenue your marketing spend produces relative to what it costs. For a home-service company, that means taking the revenue you can attribute to ads, campaigns, and lead sources and comparing it to the dollars you spent on those channels. A positive marketing ROI means campaigns are paying for themselves and generating profit. A negative or unknown ROI means you are funding growth on gut instinct.

Marketing ROI is not the same as ROAS (return on ad spend), which measures platform-level gross revenue per ad dollar without netting costs. And it is not the same as cost per booked job, which measures lead acquisition efficiency. Marketing ROI is the true profitability view: what did the spend net you, after subtracting what you paid?

How the math works

To calculate it, subtract marketing spend from the revenue attributable to marketing (tied back through call tracking and CRM job-source tagging), divide by the spend, and multiply by 100. A single blended, company-wide figure is fine for an executive glance.

But a blended number hides wide channel-level variance: one source can be returning several times its spend while another runs flat or negative, and without the breakdown you renew every budget without knowing which one is the problem. Datacube's marketing board pulls campaign revenue, leads, and revenue per lead by source from the CRM (ServiceTitan's Campaign Summary report); because spend lives in the ad platforms, ROI is derived by comparing that attributed revenue against the spend you connect.

Data sources needed to calculate it

You need three things: spend data from your ad platforms (Google Ads, LSA, social), revenue attribution data from your CRM (job source tagging in ServiceTitan, Housecall Pro, or Workiz), and a call tracking layer (such as CallRail) that ties inbound calls back to a specific campaign. Without all three connected, you are running marketing spend on faith. When those sources are consolidated, tracking marketing ROI by channel in real time becomes straightforward.

Who owns it and how often to review it

The marketing leader owns the channel-level number; the owner or GM owns the blended company view. Review it weekly at the channel level to catch a campaign bleeding budget before the month is over. Review it monthly in the business performance meeting to compare channel ROI and reallocate spend. In peak season (summer for HVAC, spring for roofing), check it twice a week as ad spend accelerates.

What good and poor marketing ROI movement looks like

Marketing ROI targets vary by trade, market, ad platform, and attribution method. Use these as directional signals, then set your own baseline from your trailing 90 days of connected data.

Warning

Data visibility gap: the attribution lag problem

Most home-service companies review marketing ROI at month-end using a report pulled from the CRM. By then, a bad campaign has already consumed its full budget, trained the algorithm on the wrong signal, and generated leads that the team chased for weeks. Attribution lag is not just a measurement problem; it is a budget problem. When marketing ROI is visible in real time by channel, you can pause a bleeding campaign on day 8 instead of discovering the damage on day 32.

Warning

Common mistake: confusing ROAS with marketing ROI

ROAS (return on ad spend) is a platform metric: Google Ads or Meta reports how much gross revenue each ad dollar generated inside their attribution window. It does not subtract what you paid, does not account for other marketing costs (agency fees, creative, call tracking), and uses the platform's own attribution model. Marketing ROI is a business metric: it nets out total spend and uses your CRM job data as the revenue source. Both numbers are useful, but ROAS will almost always look better than true marketing ROI, and confusing the two leads to overconfident budget calls.

Owner takeaway

  • Blended marketing ROI hides channel-level problems. Break it out by source every week so you can shift budget before the month is over.
  • ROAS and marketing ROI are different numbers. ROAS is a platform metric; marketing ROI is a business metric that nets out your full spend and uses CRM revenue as the source of truth.
  • Attribution quality determines ROI quality. Without connected call tracking and CRM job source tagging, marketing ROI is a guess dressed up as a number.
