What it means
An online store may charge for delivery below a certain cart amount and waive the charge above it, and customers sometimes add an item to qualify, hoping the added contribution helps the merchant pay for shipping. Suppose a store offers free standard delivery on eligible orders of at least $150; a customer with $135 of qualifying items may add $20 to cross the line.
State whether taxes, discounts or gift cards count toward the threshold. Free shipping does not remove the actual courier or fulfilment expense, so the seller needs to know its typical delivery cost and gross profit on additional basket items.
Shopify's merchant guidance describes conditional free shipping and stresses clear eligibility, geography, time and exclusions, and a banner saying "free delivery" without the conditions can frustrate customers at checkout. Average order value is a useful starting observation, not a mandatory formula, because a fixed percentage above today's average may fail when products have very different margins, so test how customers actually change baskets.
Order economics should include fulfilment, packaging, payment fees and expected returns where material, since a low-margin item added to reach the threshold may contribute little toward shipping. The threshold can change conversion: a high minimum may cause shoppers with small orders to leave instead of adding items, so track completed orders and total contribution, not only average basket value.
A test might compare two thresholds across similar customer groups or periods, measuring conversion, basket size, shipping subsidy and order margin while accounting for promotions or seasonality that could otherwise explain a change. The offer may differ by delivery area, as a nearby zone can be cheaper to serve than a remote one, so make geographic limits plain rather than surprising a shopper after entering an address.
Bulky or fragile goods may need exclusions or a separate delivery charge, which is a commercial decision, but the site should explain it before payment so a customer knows the total cost in time to choose. Returns can alter the economics, because if a customer returns the item that lifted an order above the threshold the store may still have paid outbound delivery, and the refund treatment must follow the stated policy and local consumer law.
A cart-progress message can help customers understand how much is left to qualify, and Baymard's checkout research notes that free-shipping information may be unclear in the cart. Avoid pressure to add an unwanted item, since a message can inform without implying that spending more is always cheaper, and show the ordinary shipping fee so the shopper can compare.
Membership or loyalty offers may give free delivery under another rule, so if several offers overlap, define which one wins, and remember that the threshold can be expressed as order value or, less commonly, item count, with cross-border sites needing separate values by market. For managers, calculate contribution after shipping rather than revenue alone, as an illustrative campaign might add $12,000 of gross profit from larger baskets while adding $8,000 of shipping subsidy, a $4,000 difference before other effects.
Delivery promises also matter, since free standard shipping may be slower than an express paid option, so make the service level and estimated arrival clear so customers do not infer free express service. A store with heavy repeat business should watch customer lifetime behaviour, but avoid using speculative future sales to excuse consistently poor order economics, because a free shipping threshold is a pricing and customer-experience tool judged by whole-order profit and customer response, not the size of the threshold itself.
In practice
Real-world examples.
Example
An invented shop offers free standard delivery on eligible orders of at least $150.
Example
A shopper adds a $20 qualifying item to a $135 cart and sees the updated shipping charge.
Example
A store excludes oversized furniture from its standard offer and states this before checkout.
Formula
Calculation
Illustrative incremental contribution = extra gross profit from threshold-driven baskets - extra shipping subsidy - other incremental costs. If gross profit rises $12,000 and shipping cost rises $8,000, the partial difference is $4,000 before other effects.
Per-order check: suppose a $150 threshold leads 300 customers to add a $20 item with a 40% gross margin, so each added item contributes $20 x 40% = $8 and the group adds 300 x $8 = $2,400 of gross profit. If free shipping costs the store $9 per order, the subsidy is 300 x $9 = $2,700. The net effect is $2,400 - $2,700 = -$300, so this particular threshold loses money on those orders unless larger baskets also bring repeat sales or lower handling costs per item.Case study
Seen in the real world.
This entirely fictional case follows Home Nest Decor, an invented online seller. Its blanket free-shipping policy cost more on bulky, low-margin orders than expected. It modelled product and zone costs, published an eligible-order threshold and tested customer response. The example claims no measured margin or conversion gain.
For the invented homeware store, imagine most baskets sit near $120 and shipping cost varies sharply by item size. The owner models several thresholds by product category and tests one. No automatic lift in sales is asserted.
Watch out
Common mistakes.
- Choosing an arbitrary percentage above average order value without margin analysis.
- Hiding geographic or bulky-item exclusions until checkout.
- Celebrating a higher basket value while ignoring conversion and returns.
Questions
People also ask.
How should a threshold be set?
Model shipping cost, margins, baskets and conversion; test a clear qualifying rule.
Can it hurt conversion?
Yes. Some shoppers may leave if the minimum or delivery fee feels too high.
Should the cart show progress?
A clear, accurate message can help, with discounts, address and exclusions reflected.
