Free Shipping: Who Really Pays? (Spoiler: You Do)

"Offer free shipping — it increases conversions!" You've heard this advice a hundred times. And it's true: 93% of shoppers say free shipping is their #1 reason to buy. Stores that offer it see 30% higher conversion rates.

What nobody tells you is how to pay for it. Because "free" just means the customer doesn't see a separate shipping charge. The cost doesn't disappear — it moves to your margins.

Can you actually afford it?

Quick test: your average order is $65, shipping costs $7.50, and your gross margin is 40% ($26). If you absorb shipping, your profit drops to $18.50 per order. Still workable. But if your margin is 20% ($13), absorbing $7.50 leaves $5.50. After payment fees, refunds, and your other costs, you might be losing money on every "free shipping" order. Run your numbers →

Three ways to make it work

Bake it into the price. Raise every product by $5-8. Customers don't see a shipping charge. But price-sensitive shoppers might bounce. Works best for premium products where $5 is a small percentage of the total.

Set a threshold. "Free shipping on orders over $75." This is the sweet spot. It increases average order value (people add items to qualify) while you only subsidize larger, more profitable orders. Most stores see the best results here.

Membership model. $9.99/month for unlimited free shipping. Only works if customers order frequently (beauty, pet supplies, coffee). Otherwise nobody subscribes.

The break-even test

Before you flip the switch: does the increased conversion rate offset the shipping cost? If your conversion goes from 2% to 2.6% on a $65 AOV, the extra revenue from more orders often covers the shipping cost. But if your margins are thin, it might not. Model different scenarios →.
