Marketing is a necessary evil, or a golden ticket, depending on who you ask. For some, it’s a creative playground of endless possibilities. For others, it’s an endless pit of spending with no obvious way to measure success. Enter Return on Marketing Investment (ROMI), the magic number that tells you whether your campaigns are driving results or just setting fire to your budget in a very artistic way.
Return on Marketing Investment (ROMI) is the marketing world’s way of justifying its existence. It tells you how much revenue you’ve generated compared to how much you’ve spent on marketing. In short, it’s the answer to every finance director’s favourite question: "Is this actually making us money?"
The basic formula looks like this: ROMI = (Revenue from Marketing – Marketing Cost) ÷ Marketing Cost × 100. If the number is positive, congratulations, you’re doing something right. If it’s negative, it might be time to rethink your strategy, fire your agency or start a side hustle.
Marketing without measuring ROI is like throwing darts blindfolded and hoping you hit the bullseye. You need to know what’s working and what’s just wishful thinking. Businesses that track ROMI can optimise their budgets, cut out wasteful spending and double down on the strategies that bring in results. More importantly, knowing your ROMI gives you leverage. It helps justify bigger budgets, gain executive buy-in and prove that marketing is more than just fluffy branding exercises and pretty graphics.
Getting a realistic ROMI requires more than just plugging numbers into a formula. To measure it accurately, you need to track every pound spent. This includes ad spend, agency fees, software costs, and even that suspiciously large "networking lunch." You also need to attribute revenue correctly. Not every sale happens because of marketing alone. Did the customer buy because of your Google ad, or was it your salesperson’s winning charm? Attribution models help separate marketing wins from sheer coincidence.
Another key factor in measuring ROMI is considering the Customer Lifetime Value (CLV). A new customer might only spend £50 today, but if they keep coming back for the next five years, their true value is much higher. Using the right time limit is also important. Some campaigns pay off instantly, while others take months to show results. Declaring victory, or defeat, too soon can lead to poor decision-making.
If your ROMI is looking a little tragic, don’t panic. There are plenty of ways to turn things around. Targeting the right audience is crucial. The best marketing in the world won’t work if you’re talking to the wrong people, so fine-tune your strategy to reach those who want what you’re offering. Optimising campaigns can also make a stark difference. A/B assessing your ads, tweaking your messaging and refining your calls to action can improve performance significantly.
Reducing wasted spend is another effective way to improve ROMI. If you’re throwing money at underperforming channels, shifting your budget towards what’s working can help. Focusing on customer retention is just as important. Getting a new customer is expensive but keeping them is much cheaper. Investing in loyalty programs, email marketing and excellent customer service can maximise lifetime value. Marketing automation tools can also save time, improve efficiency and ensure leads don’t slip through the cracks.
Return on Marketing Investment isn’t about proving that marketing works, it’s about making it work better. Whether your budget is big or small, tracking ROMI ensures you’re spending smartly, reaching the right people and getting actual results. So, next time someone asks if marketing is worth the investment, you’ll have the numbers to prove it. And if they still don’t believe you, just remind them that even the best products won’t sell themselves, unless, of course, they happen to be ice cream on a hot day.
