ROI (Return on Investment) measures the profit generated from a marketing or business effort relative to its cost, usually expressed as a ratio or percentage and attributed using tools like Google Analytics (opens in new tab). A campaign costing ₹5,000 that generates ₹20,000 in new business has a strong positive ROI; one that costs more than it returns has negative ROI.
The Attribution Problem That Makes This Tricky
Calculating ROI accurately depends entirely on knowing which specific effort actually generated a given piece of revenue, which is harder than it sounds once several marketing channels are running at once. UTM tracking, a "how did you hear about us" field at booking, or a dedicated tracked phone number for a specific campaign are all practical ways to attribute revenue correctly rather than guessing.
Some efforts, like SEO and content marketing, also pay off gradually rather than immediately, which means a fair ROI calculation for those needs to look at a longer time window than a single month.

How do I calculate marketing ROI for a small business?
Subtract the cost of the effort from the revenue it directly generated, divide by the cost, and multiply by 100 — (Revenue − Cost) ÷ Cost × 100 — using UTM tracking or a booking source field to attribute revenue accurately.
