What's the cost-benefit analysis framework for discount strategies?

Question

As an e-commerce business owner, I'm struggling to understand how to evaluate discount strategies beyond simple revenue numbers. I need a comprehensive framework that helps me analyze the true impact of discounts on my business, considering factors like customer acquisition, long-term value, profit margins, and potential brand perception. How can I systematically assess whether a discount campaign is truly beneficial or potentially harmful to my overall business performance?

Cost-Benefit Analysis Framework for Discount Strategies
Most stores track discount redemption, not discount ROI. These are very different things. A cost-benefit framework ensures discounts generate more value than they cost - every time.

The Framework

ComponentHow to Calculate

Incremental revenueRevenue from discounted orders MINUS baseline revenue (what you would have earned without the campaign)
Total discount costSum of all discount value redeemed in the campaign period
Margin impactGross margin % with discount vs. without - must stay above your minimum margin floor
CLV upliftFor acquisition campaigns: expected lifetime value of new customers vs. discount cost
Net benefitIncremental revenue - Total discount cost - Operational cost of running the campaign

Decision Rules

Run the campaign if incremental revenue exceeds 3x discount cost
Optimize targeting if ROI is 1.5-3x (marginal - may be giving discounts to buyers who didn't need one)
Stop or redesign if ROI is below 1.5x (discount is cannibalizing margin without generating new orders)

Common Mistakes in Discount CBA

MistakeWhy It Distorts the Analysis

Counting all discounted revenue as incrementalMany buyers would have purchased at full price - discount just reduces margin
Ignoring repeat purchase probabilityA 10% discount for a customer who returns 5x has much higher ROI than one-time buyer
Not tracking baseline without discountNo baseline = no way to measure incremental lift

Growth Suite CBA Advantage
Growth Suite's dedicated buyer protection eliminates the biggest CBA distortion: giving discounts to customers who would have purchased without one. Only walk-away visitors receive offers, making the incremental revenue calculation significantly cleaner. The Funnel Report gives you the baseline and discounted conversion data side by side for easy comparison.
