What is marketing ROI?
- Measuring return on marketing spend
- A basis for deciding where to spend more
- Look at long-term brand effects too
Once you start attaching marketing ROI to results, the first thing that changes is the conversation in marketing meetings. A report like 'The response at this trade show was great' becomes 'KRW 48 million (≈ US$35,900) on booth and staff, 62 qualified meetings, and 3 deals won worth KRW 210 million (≈ US$157,100).' The moment marketing speaks in numbers, it earns the right to argue at the same table as sales and finance. The real change is that, during budget season, you can be the team asking for an increase rather than the one getting cut.
Start by settling the calculation basis. ROAS is revenue against ad spend, while ROI is based on profit. With KRW 100 million (≈ US$74,800) in revenue and a 30% contribution margin, profit is KRW 30 million (≈ US$22,400). If you spent KRW 10 million (≈ US$7,480) on marketing, ROI is (30 − 10) ÷ 10, or 200%. Dividing by revenue instead gives a figure inflated three to four times over the real one. In B2B, where winning a deal can take more than a year, it is more realistic to also track 'pipeline ROI', the pipeline value created divided by cost, as a leading indicator.
Aligning time periods is no easy task either. In a market where it takes 6–18 months from first contact to a won deal, dividing Q1 marketing spend by Q1 revenue forces together two unrelated periods. ROI calculated within the same quarter almost always lies. The numbers only mean something when you group cohorts by when the conversation started, not when the money was spent, and then follow what that group produced 12 months later.
The most common mistake is piling budget into the channels with the highest ROI. Branded search ads and retargeting can show ROI of 800%, but they only harvest people who already know you. Activities that create the first touchpoint, such as content, webinars, and trade shows, show low ROI. Cut them and the numbers look better for two quarters, then six months later there is nothing left to harvest. ROI is not a channel league table; it is a portfolio diagnostic. Before cutting a channel because its ROI is low, check how much of the other channels' results rides on the first touchpoints it created.

Let's look at a hypothetical case. Company A makes industrial sensors and controllers, with 180 employees and annual revenue of KRW 62 billion (≈ US$46,386,400). Of its KRW 400 million (≈ US$299,300) annual marketing budget, KRW 260 million (≈ US$194,500) went to three trade shows, yet no one could say which channel led to won deals. The three-person marketing team decided to spend six months attaching ROI to each channel.
- The marketing manager pulled 148 deals won over the past 24 months from the CRM and filled in the 'first touchpoint' field. Forty-seven were blank, so they called the sales reps one by one and asked, "Where did you first meet this customer?"
- They sat down with the finance team to pin down contribution margin by product line. The spread was wide, from 22% to 41%, so they changed the standard to convert results using contribution margin by product line rather than revenue.
- The numbers split three ways: trade shows 60% ROI, technical webinars 340%, and joint direct mail with distributors 20%. When someone suggested dropping trade shows, the head of sales pushed back: "Half of our first touchpoints with new accounts come from trade shows."
- So they cut trade shows from three to two and moved the KRW 86 million (≈ US$64,300) saved into webinars and technical content. They also set a rule: demand-generation channels are evaluated on pipeline ROI, not on won-deal ROI.
- Twelve months later, the qualified pipeline had grown from KRW 3.4 billion (≈ US$2,543,800) to KRW 5.1 (≈ US$1) billion, and the ROI on marketing-attributed wins rose from 110% to 190%. The CEO approved next year's budget, up from KRW 400 million (≈ US$299,300) to KRW 520 million (≈ US$389,000).
