# Free Shipping Threshold Calculator Canonical URL: https://growthops.tools/tools/free-shipping-threshold-calculator/ Page type: Interactive tool Updated: June 15, 2026 ## Quick Answer A good free shipping threshold nudges customers toward a realistic larger basket while producing enough extra gross profit to cover the shipping subsidy. ## Use When Use Free Shipping Threshold Calculator when a store decision needs a clear next step instead of a vague note. ## Output A plain-language result, practical caveats, and follow-up actions the team can save or share. ## Inputs - Current average order value - Gross margin percent - Average shipping cost - Target basket lift percent ## Method The calculator compares your desired basket lift with the revenue lift needed to cover shipping at your gross margin. Use the larger number as the first threshold to test. ## Limits The simple model uses average shipping cost and gross margin. Heavy products, split shipments, zone-based shipping, subscriptions, and discount stacking may need separate threshold rules. ## Why this matters in a real store Free Shipping Threshold Calculator matters because ecommerce growth work usually breaks down in the handoff between a number, a platform warning, a campaign idea, and the person who has to make the next decision. A store team may know something is wrong, but still lose time because the issue is not written in a way that connects the symptom to a next action. Use this page as a practical translation layer. The goal is to slow down the first reaction, name the business risk, and give the team enough context to decide whether the next move is a calculation, a feed change, a campaign QA step, or a page update. The tables and checklists are there to make the work repeatable, but the judgment comes from understanding why the issue appears in the first place. ## What a free shipping threshold has to prove A threshold should increase basket size enough to cover the shipping cost you absorb. The calculator compares two pressures: the basket lift you want and the extra gross profit needed to pay for shipping. Worked example: If current AOV is $68, gross margin is 58%, and shipping costs $8.50, you need about $14.66 in extra revenue at that margin just to cover shipping. A threshold below that may lift conversion but still reduce contribution. ## Good threshold vs bad threshold Threshold type | What it does | Risk Just above current AOV | Encourages one extra item or a bundle add-on | May be too low to cover expensive shipping. Based on shipping cost and margin | Protects contribution better | May feel unreachable if product prices do not ladder naturally. Copied from a competitor | Easy to choose | Ignores your product cost, shipping zones, and bundle behavior. Category-specific | Matches real basket patterns | Requires more setup and testing. ## What to check before launching Can common two-item or bundle combinations reach the threshold naturally? Does the threshold work for heavy or low-margin products? Do shipping zones change the economics? Will customers see the threshold early enough in cart and product pages? Will the offer apply to discount-code orders too? ## Reference rules Shopify Help: Free shipping discounts: https://help.shopify.com/en/manual/discounts/discount-types/free-shipping ## The tradeoff behind the number A free shipping threshold is not just a cart message. It changes how customers build orders and how much contribution the store keeps. If the number is too low, customers who would have bought anyway receive a subsidy. If the number is too high, the offer becomes a banner people ignore. The right threshold usually sits where product prices, margin, and customer behavior meet. A store with natural add-ons can use a threshold to build baskets without much friction. A store with heavy products or uneven price points needs more caution, because the threshold can increase operational cost faster than it increases profit. ## Threshold QA before launch Test top five product combinations against the threshold. Check heavy products and low-margin products separately. Confirm cart messaging appears before checkout. Review how returns affect subsidized shipping orders. Set a stop condition if contribution margin falls. ## Common Questions ### Should the threshold be just above current AOV? That can work if one natural add-on gets shoppers there and the added gross profit covers shipping. ### What if shipping costs vary by region? Model separate thresholds or exclusions for regions where the subsidy changes the economics. ### Can free shipping hurt profit while helping conversion? Yes. If customers receive the subsidy without adding enough basket value, conversion can rise while contribution falls. ## Downloads - Download margin model CSV: https://growthops.tools/downloads/ecommerce-margin-model.csv ## Related Pages - Free Shipping Threshold Guide: https://growthops.tools/guides/free-shipping-threshold-guide/ - Promo Planning Template: https://growthops.tools/templates/promo-planning-template/ - Ecommerce Profit Margin Calculator: https://growthops.tools/tools/ecommerce-profit-margin-calculator/ ## References - Shopify Help: Free shipping discounts: https://help.shopify.com/en/manual/discounts/discount-types/free-shipping
