How Does Free Shipping Work: 6 Clever Ways to Offer it

Written by Caleb Bruski | Jun 1, 2026 9:47:07 PM

More and more, online buyers have come to expect perks like free shipping. And many will shop around if your store doesn’t offer it.

McKinsey found that more than 95% of consumers prefer free standard delivery over paid expedited delivery. And according to Baymard, 39% of shoppers abandon checkout because extra costs are too high, while 21% abandon because delivery is too slow. The problem, of course, is that free shipping is never actually free for retailers.

How Does Free Shipping Work?

Free shipping works by removing the separate shipping fee from the customer’s checkout experience. The retailer still pays the carrier or fulfillment provider, but covers that cost through product pricing, order minimums, shipping zones, product exclusions, customer groups, slower delivery methods, or limited-time promotions.

The goal is not to make shipping magically cost nothing. The goal is to offer free shipping only where it supports conversion, average order value, and profit margin.

Calculating a Free Shipping Minimum Spend Threshold

To calculate a free shipping minimum spend threshold, first analyze your average order value (AOV). This metric can be obtained by dividing your total revenue by the number of orders. From there, increase that value enough to help cover shipping costs while encouraging customers to spend more per order. 

A simple starting point is:

Free Shipping Threshold = Average Order Value + Enough Extra Revenue to Cover Average Shipping Cost

You also need to factor in your profit margins and the additional costs of shipping to ensure you’re not eroding your profits. For instance, if your AOV is $45 with a profit margin of 20%, you might set your free shipping threshold at $60 to encourage larger orders while still maintaining a profitable margin.

But if your products are heavy, oversized, low-margin, or frequently split across shipments, you may need a higher threshold or more restrictions. Thankfully, there are clever ways to configure your eCommerce shipping strategy to alleviate the cost of free shipping. Here’s how:

1. Limit Free Shipping to Certain Locations

Limit your free shipping by geography. You can save your free shipping offer for the people in your country or region.

For example, shipping to Alaska, Hawaii and across borders is generally more costly than shipping to the contiguous 48 states. 

How to limit free shipping to a certain zone: You can easily set a Shipping Rule in ShipperHQ to limit free shipping.

2. Set Promotional Thresholds

As shoppers, we’ve all run into online stores offering “Free shipping on purchases over $50.” Why not be that store?

Promotional shipping is a temporary or conditional shipping offer used to encourage a specific action, such as spending over a threshold, buying certain products, joining a loyalty group, or ordering during a campaign window. Free shipping is one of the most common promotional shipping offers.

The threshold persuades shoppers who may have visited your store for one thing to add extra items to their carts. Plus, it ensures you make enough profit on the sale to cover the cost of free shipping.

To manage the costs of free shipping, you can implement several strategies. First, consider bulk purchasing shipping supplies to secure volume discounts. Second, negotiate rates with multiple carriers to ensure you’re getting the best deal. Third, integrating a shipping software solution can automate rate comparisons and optimize shipping methods based on cost-efficiency. Lastly, consider utilizing economy services such as UPS Ground Saver or FedEx Ground Economy. These services are designed for lower-cost, less urgent residential deliveries.

How to set promotional shipping thresholds: In ShipperHQ, you can set promotional thresholds in just a couple minutes by adding a new Filter and Shipping Rule.

The Advantages of Free Shipping Offers

Free shipping offers can have transformative effects on e-commerce businesses. Firstly, they can increase the average order value, as customers are incentivized to reach the minimum spend threshold for free shipping. 

Secondly, they can substantially reduce cart abandonment, a common problem caused by unexpected shipping costs added at checkout. 

Thirdly, by meeting customer expectations of free shipping, businesses can boost customer loyalty and drive repeat purchases. 

Finally, in an increasingly competitive e-commerce landscape, offering free shipping can distinguish your business from others that charge for delivery. 

Moreover, consumers perceive free shipping as a significant value-add, often preferring it over discounts on products.

3. Limit Free Shipping to Certain Products

Offering free shipping on a refrigerator is likely going to cut into your margin on said refrigerator, and on other sales.

To prevent this from happening, you can limit free shipping to lightweight products only.

How to limit free shipping to certain products: Login to ShipperHQ and create a “Shipping Group.” From here, you can exclude any product(s) you want from any free shipping promotions your store offers.

4. Offer Free Shipping to Certain Customer Groups

They say you’re not supposed to pick favorites. But honestly, segmenting customers is a great way to make more bang for your buck on free shipping.

This can include segmenting frequent buyers, long-time customers, big spenders, or customers in a certain geographic location. It can also be any other customer group to whom you’d like to offer free shipping.

How to offer free shipping by customer group: Most eCommerce platforms allow you to segment customers into Customer Groups. Once you’ve segmented your customers in the backend of your preferred platform, you can then set up a Shipping Rule in ShipperHQ.

5. Delay Free Shipping and Incentivize Faster Shipping

Chances are your customer wants their order yesterday. Keeping this in mind, one strategy to keep free shipping low is to only offer it on slower methods like economy and ground. You can even delay the dispatch on these goods, if that makes more sense for your business. 

For many retailers, the cleanest setup is free standard shipping with paid upgrades for faster delivery. That gives shoppers a free option while still letting you recover costs when someone needs two-day, next-day, or same-day delivery.

Another common strategy is to add a surcharge for two-day, next day or same day shipping.

Why a surcharge? Keep in mind that many customers need their item as quickly as possible. By adding a surcharge to faster shipping, you can defray the cost of offering free shipping to customers who don’t mind receiving their items at a snail’s pace.

How to add a surcharge to certain shipping methods: ShipperHQ allows you to easily set surcharges on certain shipping methods.

6. Pay Attention to Dimensional Shipping

Size matters. The size of the box you ship your product in, that is.

To save money on dimensional packing, instruct your pickers and packers to use the smallest box or packaging unit available for the order. And try to pack multi-item orders into one package whenever possible.

By doing this, you’ll automatically save on shipping when you use the smallest size boxes and the least amount of cartons.

How to maximize savings with dimensional shipping: ShipperHQ’s Dimensional Packing Advanced Feature can guide your pickers and packers to the right box for every shipment, a feature that most eCommerce carts built-in shipping lacks. 

Turn on Dimensional Packing in your ShipperHQ account to achieve more accurate shipping rates especially when getting rates from carriers like UPS and FedEx or when using USPS Flat Rate boxes.
