What a Threshold Is Meant to Do

A free-shipping threshold is a trade-off rule: the customer pays delivery below a chosen basket value, and the merchant absorbs it at or above that value. A lower threshold can remove more delivery friction, which may help conversion, but it also puts delivery cost on more orders. A higher threshold protects more orders from that cost, but may leave customers unwilling to add enough product to qualify.

The threshold should change basket economics, not just the shipping message. For illustration only, if a customer has a $100 basket, pays $10 for delivery, and adds a $20 item to reach a $120 threshold, the merchant gives up the $10 delivery charge and incurs the delivery expense. The extra item must therefore contribute enough after its product cost and other variable costs to justify that trade-off. A basket that crosses the threshold is not automatically a profitable basket.

Define whether the threshold uses the merchandise subtotal before tax, the checkout total after tax, or another rule. This matters in Canada: the Canada Revenue Agency lists 5% GST for Alberta and Ontario’s 13% HST, among the rates by province. A $100 pre-tax threshold appears as $105 in Alberta and $113 in Ontario, while a $100 tax-inclusive threshold requires different merchandise subtotals. State the rule clearly so customers and internal reporting use the same basis (Source: Canada Revenue Agency).

Finding the lowest safe threshold

Start with the basket value at which absorbed delivery still leaves acceptable contribution. Use the merchandise subtotal before tax, rather than treating GST or HST as money available to fund shipping. For each candidate threshold, calculate: merchandise revenue − COGS − shipping cost − allocated advertising cost. For illustration only, a $120 basket with $48 COGS, $18 delivery and $12 advertising leaves $42 before other operating costs. A $90 basket with $36 COGS, the same $18 delivery and $9 advertising leaves $27.

Test more than the average order. Home decor freight can change sharply with parcel size, weight and destination, so check the common expensive combinations and Canadian delivery zones. The lowest safe threshold is the lowest candidate that keeps the selected contribution floor intact for those orders, not the threshold that produces the highest number of qualifying checkouts. If tax-inclusive pricing is used on-site, document the conversion so the threshold is applied consistently to the pre-tax subtotal.

Use each measure for a different decision. A shipping-cost ratio shows whether delivery is consuming too much of the basket; gross margin shows whether the product economics can support the offer; contribution after advertising shows whether acquisition costs leave room for absorbed delivery. ORVX computes COGS, gross profit and margins, reports contribution after advertising by product and collection, and uses delivered orders for realized revenue rather than counting cancelled or returned orders. That makes it useful for checking whether a proposed threshold works across actual product economics, while your carrier invoices and order records supply the delivery-cost input.

Worked example with sample numbers

This example is illustrative. It uses sample numbers for a home decor store selling in Canada. They are made up to show the method, they are not a benchmark, and your own figures will differ.

Formula: Lowest safe basket = (delivery + packing + fixed fee) / (gross margin rate - percentage fee - minimum margin you will accept).

Items that lift the basket

The products that lift a basket are not necessarily the products with the highest price. Look for items that are easy to add to an existing order, have reliable margin, and do not create a disproportionate increase in parcel size or handling. In home decor, that often means cushion covers, candles, small frames, table linens, hooks, or replacement hardware that complements a larger purchase.

Compare add-ons by incremental profit, not by their ticket value. For illustration only, a $18 accessory with a $7 product cost and $6 of additional delivery and handling leaves $5 before advertising. A $35 accessory with a $20 product cost and the same $6 delivery cost leaves $9. The second item lifts profit more, even though both move the basket above the threshold. Check whether returns, breakage, or extra packaging change that calculation.

Use product-level and collection-level profitability to separate genuine basket builders from products that merely increase revenue. A high-margin small item may be suitable for a cart recommendation; a bulky lamp may push the order into a more expensive shipping tier and reduce contribution. ORVX can show these differences alongside contribution after advertising, product cost, and return value. For a quick margin check before testing an add-on, use the product pricing calculator.

  • Best for frequent add-on prompts: complementary, compact products with clear use alongside the main item.
  • Best for collection merchandising: coordinated products that encourage a second item without requiring a discount.
  • Best for inventory clearance: slow-moving items only when their remaining margin and shipping impact are acceptable.
  • Act on product profitability when choosing what to recommend; act on collection profitability when deciding which room, style, or category to merchandise together.

Measuring the result

Measure the threshold against both customer behaviour and order economics. Track conversion rate, average order value, the share of orders reaching free shipping, and shipping cost absorbed per qualifying order. A higher average order value is not automatically a win: if customers add low-margin items or returns increase, contribution can fall. Compare these measures with a similar pre-change period or a controlled threshold test, keeping province, device, campaign mix and seasonality consistent.

The action depends on which measure moved. If threshold attainment and contribution rise without a material conversion decline, keep testing the offer across relevant collections. If conversion improves but contribution after advertising falls, review the threshold, product mix and shipping subsidy. If orders qualify but return value rises, inspect the products driving those baskets before scaling the offer. ORVX reports realized revenue from delivered orders, return rate and refund value against revenue, product and collection profitability, and contribution after advertising. It also keeps trading currencies separate and connects to Shopify and advertising accounts, so the comparison uses your store’s own numbers rather than blended currency or gross order totals. Ask ORVX can answer follow-up questions about the affected products, collections and customers.

Compare Shipping Policies Before Choosing a Threshold

A free-shipping threshold is designed to increase basket value: delivery is absorbed only when the order reaches a defined subtotal. It suits home decor stores when added items contribute enough margin to cover fulfilment and delivery, and when encouraging a larger basket is part of the growth strategy.

A flat-rate policy charges the same delivery fee, or a small set of fixed fees, regardless of the exact carrier cost. Use it when most orders have similar package sizes, destinations and delivery costs. Its predictable checkout experience is less suitable for stores shipping both small accessories and bulky furniture unless the rate includes a deliberate cushion.

Carrier-calculated shipping passes the quoted rate to the customer based on destination, dimensions, weight and service. It fits oversized or geographically dispersed inventory where delivery costs vary too widely for one threshold or flat fee. The trade-off is less price certainty before checkout.

Conditional shipping combines rules: for example, free delivery on qualifying collections, a surcharge for oversized items, or different treatment by province or delivery zone. Choose it when product-level or regional economics differ materially. Review each rule against delivered-order margin, not merely the shipping fee collected.
