Retail Analytics: Measuring the ROI of Same Day Delivery Services
By Kris Van der Bijl ·
Same-day delivery is an investment. Like any investment, it needs to be measured against returns. Here are the key metrics and analytical approaches to quantify the ROI of your same-day delivery service.
Conversion Rate Lift
Compare conversion rates for customers who see same-day delivery availability at checkout versus those who don't. The difference represents the direct revenue impact of the delivery option on completed purchases.
Average Order Value
Do customers ordering same-day delivery spend more per transaction? If so, faster delivery correlates with higher cart values — a positive ROI signal that offsets higher delivery costs.
Repeat Purchase Rate
Track whether customers who experience same-day delivery purchase again at a higher rate than customers who used standard delivery. Repeat purchase rate is one of the most powerful indicators of the long-term CLV impact of fast delivery.
Cart Abandonment Rate
Analyse checkout abandonment by delivery option selected. High abandonment at the delivery selection stage — particularly when same-day is not available — indicates unmet customer expectations and a direct revenue cost.
Delivery Cost Per Order
Calculate your fully-loaded cost per same-day delivery, including courier fees, packaging, and any associated technology costs. Compare this to the revenue generated by same-day orders to determine per-order profitability.
Net Promoter Score by Delivery Type
If your NPS surveys segment by delivery type, same-day delivery customers typically produce higher scores. Higher NPS correlates with higher referral rates and lower churn — both of which contribute to ROI.
