How To Measure The ROI Of Discount Coupons?

If you're looking for a direct means to measure the ROI of your discount coupon campaign, you could simply compare the revenue with the costs and weigh it out. But there's more to it. More often than not, coupons have been great tools for increasing sales, customer loyalty, and brand awareness. The challenge, however, arises when you’re actually trying to measure their impact and ROI.
Today, 8 out of 10 buyers keenly look for loyalty and reward programs before making a purchase. This makes it quite apparent that discount coupons are of the essence, especially in the USA. Marketers take extreme measures to ensure that these promotions impact the growth of their overall business, rather than simply eating into their profits.
This guide will walk you through correctly measuring the ROI of your discount campaigns by using real-life examples and case studies at every step.
Key Steps to Measuring Coupon ROI
1. Set Clear Objectives and KPIs
If you have a specific set of goals and Key Performance Indicators (KPIs) listed, you know you're off to a great start. Make sure you ask yourself what you want to achieve with the discount: Is it increased sales, customer retention, or brand exposure? Without these objectives, it’s nearly impossible to measure your campaign’s effectiveness.
For example: You decide to run a campaign wherein you offer $10 for every purchase higher than $50. You could probably set your KPI as “number of repeat customers” or “average order value increase.” This could easily help you track how well your discount strategy is working out for you, and whether or not it eventually converts to profits.
Amazon’s Prime Day Strategy
I personally find Amazon's yearly Prime Day discounts a great example of how well businesses can set clear KPIs. During their Prime Day events, notice how Amazon's focus is not just on their sales; they also look at other metrics like new Prime sign-ups, customer retention rates after the event, and even cross-selling success. All of these contribute to the long-term value that eventually most businesses wish for.
2. Track Campaign Costs and Revenue
An easy way to measure ROI would be by comparing the total revenue received from your coupon campaign to the costs involved when running it. Don't forget to include your advertising costs, the discount amount, distribution costs, or any other miscellaneous costs involved in your campaign.
I came across this formula to calculate the basic ROI for a discount campaign:
ROI =
(Revenue Generated from Campaign – Cost of Campaign) / Cost of Campaign x 100 |
Now let's say, your campaign generated $50,000 in sales and the total cost involved was $10,000, your ROI would be:
ROI = (50,000 – 10,000) / 10,000 x 100 = 400% |
This very clearly shows that you got a 400% return, or the profit you earned after your event was a good $40,000.
3. Use Single – Use Promo Codes
If you're looking for a simpler and more reliable way to track coupon ROI, try using unique single-use promo codes for your campaign. With this, you know that every code is tied to an individual customer, so when these codes are used, you get accurate data on who used the coupon and under what conditions. As simple as that. The best part is, with this, you can avoid fraud or code leakage which usually hamper your results.
Example: Sephora’s Beauty Insider Coupons
I've noticed how smartly Sephora uses this strategy for its Beauty Insider members. The brand offers single-use coupons to members and with this, tracks how many new customers join their program while also checking up on their existing members to see any increase in additional purchases. So Sephora not only gets to calculate their direct revenue from the campaign but also checks on the customer lifetime value or what is known as CLTB gained from their promotions.
4. Monitor Coupon Redemption Rates
If your priority is to understand how well you did in getting customers to act on your campaign, find out the coupon redemption rate. I find this an extremely effective route to measure the ROI of your discount coupon campaign. Here's a formula you could use:
Redemption Rate =
(Number of Redeemed Coupons / Number of Distributed Coupons) x 100 |
For example: Say you distributed 10,000 coupons and 2,000 were redeemed, the redemption rate would be 2000/10,000 x 100 which is 20%. If your redemption rate is low, this could imply that the offer may not have been as compelling or possibly wasn't marketed well.
5. Test and Optimize Different Discount Variations
I'm sure you must've heard of the A/B testing; a personal recommendation if you're looking to optimize your discount strategy. There are different discount types and deals that you can put to test: percentage vs. dollar amount, limited-time offers, or even using different channels to distribute coupons.
How you can go about this: Run two identical campaigns but offer 10% off in one and $5 off in the other. See which offer brings in more revenue and better customer engagement, and based on the KPIs you set, choose the one that best fits.
Example: Best Buy’s Seasonal Campaign Testing
During Black Friday events and other holiday seasons, have you noticed how Best Buy offers different discount offers on their page? Some coupons are percentage-off ones while other offers are massive bundle deals. This makes it easy for them to assess which discount structure helped generate more traffic and conversions. So based on this assessment, Best Buy can optimize future campaigns and rectify mistakes from past performances.
6. Avoid Fraud and Ensure Accuracy with Automation
What are the odds that you're running a coupon campaign and you don't come across fraudulent activity? We've seen enough examples of that to know that using software for an automated coupon generation process is essential. As a matter of fact, many e-commerce platforms integrate built-in tools not only to track redemption but also to prevent misuse, and often analyze the real-time effectiveness of the campaign.
Example: Walmart's Digital Coupon System
Did you know that Walmart uses advanced coupon tracking and automation for the security of its exclusive coupon codes? This system makes it easy for them to catch any fishy activities and remove undesired codes even before they affect the campaign's ROI.
Some Coupon KPIs To Keep In Mind
Break-Even Point: It calculates how many units you need to sell to break even. That is when your campaign neither makes nor loses money. This is a key indicator showing you the point at which you have covered costs but have not started generating any profits.
Coupon Redemption Rate: This shows the proportion of coupons sent out that were redeemed.
CLTV, or Customer Lifetime Value: Coupons are not just for one-time transactions. Measure the lifetime value of customers gained through coupon campaigns.
Incremental Sales: Track sales that would have never taken place except for the coupon being offered.
Conclusion
It's only natural to expect a return from an investment that you make. When it comes to coupons and discounts, it's a large play of trial and error at first. But gradually, once you know what pulls the customers and more importantly when, you'll have your fair share of wins. This is what necessitates measuring the ROI of any campaign. More importantly, make sure you set your goals clearly so you know if your campaign has proved effective.
