About

Marketing is no longer an expense; it is an investment. The Return on Marketing Investment (ROMI) metric quantifies the financial value generated by marketing campaigns. Unlike general ROI, ROMI is often calculated on short-term horizons to evaluate specific campaign performance (e.g., a Black Friday PPC blitz or an Email Nurture sequence).

This tool helps marketers distinguish between Organic Baseline Revenue (sales that would have happened anyway) and Campaign-Driven Revenue. By isolating the incremental lift, you can accurately report to stakeholders which channels (SEO, PPC, Social) are printing money and which are burning it.

Formulas

ROMI calculates the efficiency of the marketing spend:

ROMI = Revenue_marketing − Cost_marketingCost_marketing × 100

Alternatively, using incremental value:

Lift = Total Rev − Organic Baseline

Reference Data

Channel	Cost Structure	Avg. ROMI Benchmark	Conversion Speed
SEO (Search Engine Opt)	High upfront / Low ongoing	500% - 1000%+	Slow (6-12 mo)
Email Marketing	Low Cost	3500% - 4000%	Fast
PPC (Google Ads)	Pay per click	200% - 300%	Immediate
Social Media (Paid)	CPM / CPC	150% - 250%	Immediate
Influencer Marketing	Flat Fee / Commission	400% - 600%	Medium
Offline (Print/TV)	High Fixed Cost	100% - 200%	Slow

Frequently Asked Questions

Generally, a 5:1 ratio (500% ROMI) is considered strong. A 2:1 ratio is often the break-even point when factoring in COGS (Cost of Goods Sold) and overhead. Any ratio below 2:1 usually indicates the campaign is losing money.

For a strict financial view, yes. You should subtract the Cost of Goods Sold from the Revenue before calculating ROMI to get 'Profitability ROMI'. This tool focuses on 'Revenue ROMI', which is standard for top-line marketing analysis, but be aware of your margins.

Look at your sales data during periods where no active campaigns were running, or use a control group (a segment of customers who did not see the ads). This helps prevent attributing organic sales to paid channels.

Email marketing typically markets to existing leads or customers (retention), meaning the acquisition cost was already paid in the past. Therefore, the marginal cost of sending an email is tiny compared to the revenue it generates.
