What Is Marketing ROI?

Marketing ROI (Return on Investment) is the ratio of the revenue generated by marketing activities to the cost of those activities. It is an essential metric for measuring the efficiency of marketing campaigns and for comparing the performance of different marketing channels, campaigns, and strategies.

Why Marketing ROI Matters
  • Measuring Investment Efficiency: You can measure how effectively the money spent on marketing activities generates revenue.
  • Optimizing Budget Allocation: By comparing the ROI of different marketing channels and campaigns, you can concentrate your budget on the most effective areas.
  • Data-Driven Decisions: You can make decisions about marketing strategy and tactics based on objective performance metrics.
  • Making the Case to Executives: Marketing teams can use ROI to demonstrate the value of marketing investment to management.
  • Continuous Improvement: Tracking how ROI changes over time shows whether marketing performance is improving.
Marketing ROI Formulas
Basic Marketing ROI Formula

Marketing ROI(%) = ((Revenue from marketing - Marketing cost) ÷ Marketing cost) × 100

ROAS (Return on Ad Spend) Formula

ROAS = Revenue from marketing ÷ Marketing cost

Worked Example

Example: If you invest 1,000,000 KRW in an email marketing campaign and achieve 5,000,000 KRW in sales, then ROI = ((5,000,000 - 1,000,000) ÷ 1,000,000) × 100 = 400%. That means a net profit of four times the amount invested.

What to Consider When Measuring Marketing ROI
Attribution Models

When there are several marketing touchpoints, how you decide which channel contributed to a conversion matters. You need to consider the various attribution models available: last click, first click, linear, time decay, and others.

The Time Factor

The effects of marketing activity may not appear immediately. Distinguish between short-term and long-term ROI, and define the measurement period clearly.

Indirect Effects

Indirect effects that are hard to measure as direct sales, such as improved brand awareness and greater customer loyalty, are also an important part of marketing ROI.

Customer Lifetime Value (CLV)

Considering a customer's full lifetime value rather than a single transaction gives a more accurate measure of long-term marketing ROI.

Include Every Cost

To calculate ROI accurately, include every related cost, such as labor, tool subscriptions, and content production, not just advertising spend.

Benchmarking

An ROI figure on its own has limited meaning. Assess relative success by comparing it against industry averages, competitors, and your own past performance.
