Is Free Shipping Worth It? Calculate Your Shipping Threshold

Written by Rick Nelson | 06. 11. 2020

They say nothing is free in life – even “free shipping.” That’s no surprise to ecommerce entrepreneurs competing against business giants, like Amazon, that offer free shipping on almost everything. Customers often expect free shipping. For online retailers, knowing how to offer free shipping – without going broke – is crucial to ensuring long-term success.

TL;DR

  • Free shipping reliably lifts conversions and cuts cart abandonment, but it pays off only when you build it around your own margins.

  • Your free shipping threshold is the cart minimum that protects margins, and the formula shows a $55 minimum trims shipping to about $2 per order versus $6 at $45.

  • You can offer it affordably five ways: raise product prices, set a cart minimum, target first-time buyers, run limited-time promos, or limit it to lighter items.

  • Partnering with a 3PL lowers the underlying cost through closest-center shipping and bulk carrier rates, leaving more room to offer free shipping.

 

“Striking a balance between profitability and your customers expectations for shipping fees cannot be taken lightly. Too often businesses lose out on valuable customers simply because shipping fees are beyond what they’re willing to pay."

- Rick Nelson, Founder and CEO, The Fulfillment Lab

Recent statistics support Rick’s sentiments:

  • Almost 60% of online shoppers say free shipping is a top factor affecting their purchasing decisions
  • 54% of shoppers will make future purchases from a retailer if they know they’ll receive free shipping.
  • 59% of customers will spend more in order to reach established free shipping minimums.

But, how can companies offer free shipping? It’s no secret that offering free shipping is easier said than done. Of course, retailers like Amazon and Walmart can afford to take the hit on free shipping, but it’s a different story for startups and small ecommerce businesses.

However, free shipping is not impossible for small- and mid-size businesses to offer, and the benefits of free shipping outweigh the costs. Here are some ways to offer free shipping and how to calculate your free shipping threshold.

First, Is Free Shipping Worth It?

In short, the answer is yes. With free shipping, retailers are better able to convert shoppers into customers, improve customer relationships, outshine the competition, and generate higher sales numbers.

While there are risks associated with free shipping, when a free shipping offer is done correctly, there are a number of benefits. Examples of these include:

  • Lower cart abandonment rates. Nearly 70% of all online carts are abandoned and shipping costs play a huge role in this. Free shipping encourages customers to complete their purchase.
  • Increased overall sales value. Would you rather spend money on a $45 item with free shipping or spend $30 on an item with a $15 shipping fee? 78% of shoppers would rather buy more to qualify for free shipping.
  • Build trust with customers. Nothing frustrates customers more than going through the checkout process only to be blindsided with a steep shipping fee at the end of their transaction. Free shipping gives customers a simple pricing structure.

Before You Begin Free Shipping - Know Your Free Shipping Threshold!

As mentioned earlier, free shipping is never “free” and someone, be it the retailer or customer, has to pay for shipping. A big mistake many online retailers make is not knowing if they can afford to offer free shipping or not having a free shipping strategy. Without careful planning, offering this type of incentive can cut too deep into profit margins and harm the business.

So, the first thing you can do is know what you can afford to offer in free shipping and how to calculate your free shipping threshold. Once you have a better understanding of the numbers you’re working with, you can establish a free shipping strategy that both your bottom line and customers will be happy with.

How To Calculate Your Free Shipping Threshold

Let’s explore how to determine what an online seller can offer in terms of free shipping. This threshold is crucial so you don’t create a free shipping program that doesn’t protect your business. Afterall, setting an arbitrary threshold could be useless to customers, or could eat up your margins.

For example, if your average order value is $50 and you set your free shipping minimum at $500, no one is going to bite. By the same token, if your average order value is $50 and you set your minimum at $40, most customers will qualify – and you’ll be taking a huge hit. The key is to find the right balance that both you and your customers can live with.

Here’s how to calculate your free shipping threshold.

  1. Calculate your Average Order Value, without shipping costs (for example, $40)
  2. Determine your Average Shipping Costs using a shipping cost formula (for example, $8)
  3. Calculate your Gross Profit Margin. To do this, subtract the Cost of Producing Product from Total Sales and divide that number by your Total Sales (for example, if your Total Sales is $100k and your Cost of Producing Product is $60k, then the formula would be ($100,000 - $60,000) / $100,000 = 40% Gross Profit Margin)
  4. Propose a Minimum Cart Value (for example, $45)

Now, it’s time to put that Proposed Minimum Cart Value to the test.

  1. Determine the difference between the Proposed Minimum Cart Value and the Average Order Value ($45 - $40 = $5)
  2. Multiply the difference by the Gross Profit Margin ($5.00 * .40 = $2)
  3. Subtract the result from the Average Shipping Cost ($8 - $2 = $6)

As you can see, you’re going to wind up paying $6 for shipping on qualifying orders, which is too much of a hit for your bottom line. So, let’s try adjusting the Proposed Minimum Cart Value. This time, use $55 as the minimum.

  1. Proposed Minimum Cart Value minus Average Order Value ($55 - $40 = $15)
  2. Multiply the difference by the Gross Profit Margin ($15.00 * .40 = $6)
  3. Subtract the result from the Average Shipping Cost ($8 - $6 = $2.00)

By upping your threshold by $10, you still provide value for customers while dropping your shipping cost to just $2.00 per order. That’s much more do-able, right? You may have to play around with the numbers a bit to find your sweet spot, but it’ll be worth it to your bottom line!

How To Offer Free Shipping: 5 Strategies To Consider

If you offer free shipping, it’s going to come out of your bottom line, and most startups and small eCommerce retailers are already working on small profit margins. How can you offer free shipping without losing money—or at least without losing much money? Here are four ways you can offer free shipping.

1. Increase The Price Of Your Product

This may seem counterproductive, but remember, customers like the simple pricing structure of a free shipping model. They may not notice that the product costs more. Instead, they’ll be attracted to the free shipping angle.

The Wharton School of Business even shows that free shipping that saves a customer $6.99 is more appealing than a discount that cuts the purchase price by $10. Again, it comes to simplicity and not asking your customers to do calculations themselves.

2. Offer Free Shipping On Orders Over A Certain Dollar Amount

Many online shoppers will add additional items to their shopping cart to receive free shipping. You wind up selling more and, by shipping the items together, can save on the cost of individual shipments. Wharton also reveals that the average consumer will increase their spend on an order up to 30% just to get free shipping.

3. Offer Free Shipping For First-Time Customers

If providing free shipping on a regular basis is not sustainable, don’t worry. There are other ways to incorporate this customer-preferred feature. Consider offering free shipping exclusively to first-time buyers as a welcome gift that also encourages them to buy.

Experiment with this strategy by generating a single-use promo code for new accounts that are making a purchase. Attracting new customers is significantly harder than persuading current customers to return, even if it means they must cover shipping costs. Therefore, this approach could be an effective method to boost new customer sales.

 

 

4. Offer A Limited-Time Free Shipping Offer

You might also consider offering free shipping for a brief period to spark a surge in sales. Why not run a special promotion for one weekend each month, or align it with major celebrations like Christmas, Mother's Day, or Father's Day?

This approach leverages the power of urgency, a proven sales booster that can skyrocket sales by as much as 332%. Set up a short-lived promo code and spread the word across your website and social media platforms.

Introducing free shipping for just a few days can be the nudge your customers need to go from thinking about a purchase to making it, potentially driving up your sales and boosting your revenue in the process.

5. Offer Free Shipping On Select Items

Depending on the types of products you sell, it may be easier to offer free shipping on some items and not others. For example, if you ship heavy items, such as organic laundry soap in glass bottles, free shipping may not be feasible for that product. However, if you have other items that cost less to ship, you may want to consider offering free shipping only on those items.

 

 

Free Shipping FAQs

What Is A Free Shipping Threshold In Ecommerce?

A free shipping threshold is the minimum cart value a customer has to hit before their order ships free. Set it too high and no one qualifies; set it too low and you eat the shipping cost on nearly every order. The goal is a number that nudges customers to add a little more without crushing your margins. For example, if your average order value is $50, a $500 threshold is pointless and a $40 one is too generous. The right threshold sits just above what shoppers typically spend.

How Do You Calculate A Free Shipping Threshold?

Start with four numbers: your average order value, average shipping cost, gross profit margin, and a proposed minimum cart value. Find the gap between your proposed minimum and your average order value, multiply that gap by your profit margin, then subtract the result from your average shipping cost. Whatever is left is what you'll pay per qualifying order. Using the article's example, a $45 minimum leaves you covering $6 a shipment, but bumping it to $55 drops your cost to just $2. Adjust the minimum until that number feels sustainable.

Is Free Shipping Worth It For Small Businesses?

Yes, when it's planned around your numbers. Free shipping helps convert browsers into buyers, lowers cart abandonment, and builds trust through simple, predictable pricing. The stats back it up: close to 60% of shoppers call free shipping a top factor in their decisions, and 59% will spend more to hit a free shipping minimum. The catch is that someone always pays for shipping, so the win comes from setting a threshold you can afford rather than offering it blindly.

How Can I Offer Free Shipping Without Losing Money?

You have five practical levers. Build shipping into your product price, since customers respond to simple pricing and may not notice a small bump. Set a free shipping threshold so orders have to clear a minimum cart value. Offer it only to first-time buyers as a welcome incentive. Run limited-time promotions to create urgency and spark a sales surge. Or limit free shipping to lighter, cheaper-to-ship items. Mixing a couple of these usually protects your margins better than offering free shipping across the board.

Does Free Shipping Reduce Cart Abandonment Rates?

It helps a lot. Nearly 70% of online carts get abandoned, and unexpected shipping costs are one of the biggest reasons buyers walk away at checkout. Free shipping removes that last-minute sticker shock and gives customers a clear, predictable total from the start. It also encourages them to finish the purchase instead of stalling over added fees. Pairing free shipping with a sensible threshold keeps abandonment down without handing away your margins on every order.

Why Do Customers Prefer Free Shipping To Discounts?

It comes down to simplicity. Research from the Wharton School found that free shipping saving a customer $6.99 is more appealing than a discount that cuts $10 off the price. Shoppers don't want to do the math, and a clean "free shipping" offer feels better than a larger saving they have to calculate. That same simplicity drives behavior, with the average consumer increasing their order by up to 30% just to qualify. For your store, that means free shipping can outperform a bigger markdown.

Can I Offer Free Shipping To First-Time Customers Only?

Yes, and it's a smart move if regular free shipping isn't sustainable. Offering it as a welcome gift to first-time buyers gives new customers a reason to complete that initial purchase. A simple way to run it is a single-use promo code tied to new accounts. Winning new customers is harder than getting existing ones to return, so this targets your budget where it has the most impact. Returning shoppers can still cover shipping, while newcomers get the nudge they need.

How Does A 3PL Help Lower Ecommerce Shipping Costs?

A 3PL can cut your shipping costs in two main ways. First, it ships orders from the fulfillment center closest to each customer, so packages cross fewer zones and cost less to deliver. Second, because a 3PL moves bulk volume with all the major carriers, it can negotiate better rates than most individual sellers can get on their own. Lower per-order shipping costs give you more room to offer free shipping without taking the full hit. The Fulfillment Lab uses both levers across its national and global centers.
