Free shipping is the #1 incentive for online shoppers. In fact, 75% of consumers expect free shipping on orders under $50. But if you offer free shipping on everything, you will go bankrupt. The secret is setting a Free Shipping Threshold that forces customers to add “one more thing” to their cart, boosting your Average Order Value (AOV).
The Math: How to Find Your Magic Number
You shouldn’t guess. You need to calculate a threshold that covers your shipping cost while feeling attainable to the customer.
The Formula:
Threshold = (Average Shipping Cost / Gross Profit Margin) + Average Order Value
Example:
- Average Order Value (AOV): $40
- Average Shipping Cost: $8
- Gross Profit Margin: 40% (0.40)
Calculation:
- Divide Shipping Cost by Margin: $8 / 0.40 = $20.
- Add to AOV: $20 + $40 = $60.
Your Threshold should be $60. If you set it at $60, the extra profit from the upsell covers the shipping cost completely.
Gamifying the Experience
Once you have your number (e.g., $60), you need to tell the customer. Don’t just hide it in a policy page. Use a Progressive Free Shipping Bar.
- Step 1: Customer adds a $40 item.
- Bar Updates: “You are only $20 away from Free Shipping!”
- Psychology: This triggers the “Goal Gradient Effect.” People speed up their behavior as they get closer to a goal.
