Free Shipping Thresholds: How to Set Them
"Free shipping on orders over a set amount" is one of the oldest tricks in online retail, and it still works. But pick the wrong number and you either give away margin on every order or set a bar so high that nobody bothers. This guide shows you how to set free shipping thresholds with your own numbers, test them calmly and adjust them for the holiday season.
Key takeaways
- Free shipping is never free: you pay for it, so the threshold has to cover that cost through bigger orders.
- Start from your current average order value and your real shipping cost per order, not from what competitors show.
- A threshold a little above your average order nudges people to add one more item without feeling out of reach.
- Test one threshold at a time for several weeks, and watch margin per order, not just sales.
Shoppers have come to expect free shipping, and a delivery charge that appears at checkout is a common reason people leave without buying. A threshold is the middle ground. It lets you offer free delivery while asking the customer to spend enough to make it worth your while.
Mid-October is a good time to review your threshold. You still have a few weeks to test a new number before the holiday rush, and you can plan any seasonal changes calmly instead of changing settings in the middle of a busy weekend.
A quick note: this is general information about pricing and marketing, not financial advice. Carrier rates, taxes and consumer rules on how prices are shown vary by country, so check your carrier's current rates and the rules where you sell.
Why free shipping thresholds work
A threshold changes how shoppers think about the last few items in their basket. Without one, a shipping fee feels like a penalty. With one, the customer sees a goal: "Add one more thing and delivery is free." Many people would rather spend that money on a product they can keep than on a fee.
For you, the threshold does two jobs at once.
- It raises average order value. Customers just under the line often add a small item to cross it.
- It spreads shipping costs. One bigger parcel usually costs less per item to pick, pack and ship than several small ones.
The catch is that every order above the line now carries a shipping cost you absorb. If the extra spending does not cover that cost, you have quietly cut your margin.
Three ways to offer free delivery
| Approach | How it works | Best for | Watch out for |
|---|---|---|---|
| Free above a threshold | Delivery is free once the basket passes a set amount | Most small shops with a range of prices | Setting the line too low or too high |
| Always free | Shipping cost is built into product prices | Shops with similar, higher-priced items | Prices that look high next to competitors |
| Free for members or at set times | Free delivery for subscribers, loyalty members or a promo window | Shops with repeat buyers | Training people to wait for the offer |
The numbers you need first
Before choosing a threshold, pull three numbers from the last few months of orders. Use a normal period rather than a sale month, so the figures reflect everyday buying.
- Average order value (AOV). Total revenue divided by number of orders. Your e-commerce platform's reports usually show this.
- Average shipping cost per order. What you actually pay for postage, plus packaging. Include boxes, tape, filler and labels.
- Gross margin percentage. What is left from each sale after the cost of the products, as a share of the sale price.
- Order value spread. Look at how orders cluster. If most orders sit in a narrow band, that band tells you where a nudge could work.
Write these down. They are the foundation for everything that follows, and you will compare against them after you change the threshold.
Common mistake
Copying a competitor's threshold. A bigger shop may have cheaper carrier rates, different margins and a different product mix. Their number tells you nothing about your costs. Use it as a sense check at most, never as your starting point.
How to set your first threshold
A common rule of thumb is to set the threshold somewhat above your current average order value, often in the range of about 15 to 30 percent higher. That is close enough that many customers can reach it with one more item, but high enough to lift the average. Treat it as a starting point for testing, not a law.
Check that the threshold pays for itself
Once you have a candidate number, test it against your margin with simple math.
- Find the extra spend you need. Divide your average shipping cost by your gross margin percentage. That is roughly how much more an order must be worth to cover free shipping from margin alone.
- Compare it with the gap. Your threshold minus your current AOV is how much more the typical customer must spend. If that gap is smaller than the extra spend you need, you will lose margin on typical orders that just cross the line.
- Look for low-cost add-ons. Check whether you have items priced to fill the gap neatly, such as small accessories, refills or gift wrap.
- Decide what to do with orders below the line. Will you charge a flat rate, the real carrier rate or offer a cheaper slow option?
Hypothetical example
Imagine Tom, who sells specialty coffee beans and brewing kit online. His average order is $38, his average shipping and packaging cost is $7 per order, and his gross margin is 50 percent. To cover $7 of shipping from margin, an order needs about $14 more in sales ($7 divided by 0.5). A threshold of $45 only asks for $7 more, so it would cost him margin on many orders. A threshold of $50 to $55 covers the shipping cost better, and he has $12 bags of beans that let customers cross the line easily. He tests $50 first. All numbers are made up for illustration.
A threshold planner you can copy
Use this table to compare candidate thresholds side by side. The amounts are made-up examples for illustration only. Swap in your own figures.
| Threshold option (example) | Current AOV (example) | Gap to threshold | Avg shipping cost (example) | Extra sales needed to cover shipping at 50% margin | Easy add-on item? | Verdict |
|---|---|---|---|---|---|---|
| $45 | $38 | $7 | $7 | $14 | Yes, $8 filters | Too low, loses margin |
| $50 | $38 | $12 | $7 | $14 | Yes, $12 beans | Test first |
| $65 | $38 | $27 | $7 | $14 | Only big items | May feel out of reach |
Add a column for "UK" or "EU" if you ship internationally. Carrier costs differ by destination, and many shops set separate thresholds, or none at all, for international orders.
Show the threshold so people use it
A threshold only works if shoppers know about it and can see how close they are. Make it visible at the moments that matter.
- Announcement bar. A short line at the top of every page: "Free UK delivery on orders over £40."
- Progress message in the cart. "You are $8 away from free shipping." Many e-commerce platforms and apps can show this automatically.
- Suggested add-ons. Show two or three small items that would close the gap, right in the cart.
- Product pages. A short note near the add to cart button reminds people before they even reach the basket.
- Emails and social posts. Mention the threshold in your holiday campaigns as a benefit, not small print.
Pro tip
Create a small range of "gap fillers": useful, low-cost items that ship easily in the same box, such as refills, cards, care products or gift wrap. They help customers cross the line and they add margin rather than just volume.
Test, measure and adjust
Changing a threshold is an experiment. Run it long enough to see a real pattern, and compare it fairly against your starting numbers.
How to run a simple test
- Record your baseline. AOV, orders per week, conversion rate and margin per order before the change.
- Change one thing. Move the threshold, but keep prices, ads and promotions as steady as you can.
- Wait several weeks. A few days is rarely enough, because weekly patterns and paydays affect buying.
- Compare the same measures. Did AOV rise? Did conversion fall? Did margin per order go up or down?
- Decide and document. Keep, adjust or roll back, and write down why.
The number to watch most closely is margin per order after shipping. Sales can rise while profit falls if you are paying for more free deliveries than the extra spending covers.
Adjusting for the holiday season
The holidays change shopping behavior. Gift buyers often place larger orders, and many are more willing to spend a little extra to save on delivery. That gives you a few options.
- Lower the threshold for a short promo window. This can be a strong offer around the big shopping weekend, as long as your margin can take it for those days.
- Keep the threshold but add gift wrap or a free gift. This protects margin while still feeling generous.
- Show last shipping dates clearly. A threshold means little if the parcel arrives after the holiday.
- Plan for carrier surcharges. Some carriers add peak season charges. Check your carrier's current terms before you commit to a low threshold.
Whatever you choose, set the end date in advance and put a reminder in your calendar to switch back. Customers who see free shipping in December may expect it in January too, so explain clearly that it was a seasonal offer.
Common mistake
Forgetting returns. If your returns policy promises free returns, a big holiday order that comes back costs you shipping twice. Factor likely returns into your holiday threshold, especially for clothing and other items that are often sent back.

- Pick two or three candidate thresholds above your AOV
- Check each one with the planner table
- Create a few low-cost gap filler products
- Show the threshold in the announcement bar, cart and product pages
- Run one threshold for several weeks and track margin per order
- Plan holiday changes with a fixed end date
- Check carrier peak charges and last shipping dates
Frequently asked questions
What is a good free shipping threshold?
There is no universal number. A common rule of thumb is a little above your current average order value, but the right figure depends on your shipping costs, margins and the add-on items you can offer. Run the math with your own numbers and test it.
Should I raise prices instead of offering free shipping?
Some shops build shipping into product prices and offer free delivery on everything. It can work well for higher-priced items, but it can make your prices look high next to competitors. A threshold is usually easier to test first.
Do I need different thresholds for different countries?
Often, yes. Shipping costs, delivery times and customer expectations vary by destination. Many shops set a threshold for domestic orders and either a higher threshold or standard rates for international ones. Also check how taxes and duties affect international buyers.

The bottom line
A good free shipping threshold starts with your own numbers: average order value, real shipping cost and margin. Set the line a little above where customers already spend, make it visible in the cart, give people easy ways to cross it and track margin per order, not just sales.
Pull your numbers this week, test one threshold before the holiday rush and plan any seasonal changes with a clear end date. A well-set threshold quietly raises every order without giving away your profit.
