ROI is shown net of marketing spend; it does not subtract cost of goods or overhead.

ROAS is gross revenue per dollar of spend — a quick efficiency signal.

For long sales cycles, match revenue to the period the spend actually influenced.

How Marketing ROI Works

ROI turns marketing from a line-item cost into a measurable investment. Here's what drives it.

01

ROI vs ROAS

ROAS is gross revenue ÷ ad spend (a ratio). ROI is profit ÷ spend as a percentage. ROAS shows channel efficiency; ROI shows whether you actually made money.

02

The ROI Formula

ROI = ((Revenue − Marketing Spend) ÷ Marketing Spend) × 100. Subtract spend from revenue, divide by spend, multiply by 100 for a clean percentage.

03

What Counts as Spend

Include ad budgets, agency fees, software, creative, and the staff time tied to a campaign. Leaving out costs inflates ROI and leads to bad decisions.

04

Attribution Challenges

Buyers touch many channels before converting. Your attribution model decides which channel gets credit — and that choice can swing ROI dramatically.

05

Payback & LTV

A customer is worth more than a single sale. Factoring lifetime value (LTV) and payback period reveals campaigns that look weak short-term but win over time.

06

Improving ROI

Raise conversion rates, lift average order value, and cut wasted spend on poor-performing channels. Small efficiency gains compound into large ROI swings.
