How do I measure the ROI of my Mother's Day promotion?

Calculating the true ROI of a Mother's Day promotion requires accounting for both the revenue generated and the costs incurred including discounts, marketing spend, and fulfillment. Merchants who calculate ROI accurately can make informed decisions about how much to invest in future Mother's Day campaigns.

TL;DR - Quick Answer

Calculate Mother's Day promotion ROI using this formula: (incremental revenue - incremental costs) divided by incremental costs. Incremental revenue is holiday-period revenue minus your baseline for the same period. Incremental costs include discounts given, marketing spend, and any additional fulfillment costs. Most well-run Mother's Day campaigns achieve 300-600% ROI on marketing spend when discounts are properly targeted rather than applied universally.

Complete Expert Analysis

Measuring Mother's Day Promotion ROI

ROI measurement for holiday promotions is more complex than standard campaign ROI because you need to separate holiday-driven revenue from baseline revenue that would have occurred regardless. Without this separation, you overstate the ROI of organic holiday lift and understate the impact of specific campaign decisions.

ROI Calculation Framework

ComponentHow to Calculate
Baseline revenueAverage of the same 21-day period in prior years (excluding previous Mother's Day peaks)
Holiday revenueTotal revenue in the 21-day Mother's Day window
Incremental revenueHoliday revenue minus baseline revenue
Total costMarketing spend plus total discounts given plus additional fulfillment cost
ROI(Incremental revenue - total cost) divided by total cost, multiplied by 100

Common ROI Calculation Errors

  • Forgetting discount cost - Discounts are a direct revenue reduction and must be included in the cost calculation
  • Including baseline revenue - Total holiday revenue overstates campaign ROI; use incremental only
  • Ignoring LTV - A campaign with low first-purchase ROI may have high LTV ROI if it acquires high-retention customers
