What financial modeling should I do before launching discount campaigns?

Question

As an e-commerce business owner, I'm struggling to understand the financial implications of launching discount campaigns. I want to ensure that my promotions not only attract customers but also maintain profitability. I need a comprehensive approach to financial modeling that helps me predict revenue impact, understand margin erosion, and make data-driven decisions about discount strategies. What key financial metrics and modeling techniques should I use to evaluate the potential success and risks of my promotional campaigns?

Financial Modeling Before Launching Discount Campaigns
Financial modeling before launch prevents the most common discount failure mode: running a campaign that looks successful in orders but destroys margin. A simple three-scenario model catches most risks before they become expensive.

Three-Scenario Model

ScenarioRedemption RateConversion LiftExpected Outcome

Best case15%+30%High incremental revenue, controlled discount cost
Base case25%+15%Moderate lift, acceptable margin impact
Stress test50%+5%Low lift, high discount cost - is margin still positive?

Model Inputs to Define

Monthly visitors: How many will see the offer?
Baseline conversion rate: What % buy without any discount?
Expected offer view rate: % of visitors who trigger exit-intent or see offer
Redemption rate: % of offer viewers who redeem
Average order value: Pre-discount
Discount depth: % or fixed amount
COGS %: To calculate margin at discounted price

Go/No-Go Decision Rules

ConditionDecision

Stress test produces positive margin AND positive incremental revenueGo - campaign is financially safe
Stress test produces negative incremental revenue but positive marginProceed with redemption cap - limit total exposure
Stress test produces negative margin at stress redemption rateRedesign - reduce discount depth or tighten targeting before launch

Growth Suite Pre-Launch Modeling Advantage
Because Growth Suite targets only walk-away visitors, your stress test redemption rate input should be much lower than for blanket campaigns. Typical behavioral targeting produces 15-25% redemption rates vs. 50-70% for sitewide discounts - which means the stress scenario is materially less severe, and campaigns that would fail a blanket discount model can pass a targeted discount model.
