Shipping Costs Keep Changing. Here’s How to Lower the Total Cost of Yo

For decades, shipping cost management tended to revolve around two moments: negotiating rates and reviewing invoices. Now, shipping costs are changing all the time.

Get the best carrier agreement you can. Audit for billing errors. Build the budget. Repeat the process next year.

That approach made more sense when carrier pricing changed less frequently.

Today, parcel pricing can shift throughout the year. The shipping-industry data you shared illustrates that trend clearly, with reported carrier pricing changes increasing from 9 in 2020 to 12 in 2021, 19 in 2022 and 36 by last year.

For businesses ordering shipping boxes, that creates an important problem.

The price you see for the box is only part of the cost.

The number that matters is:

Box price + shipping = actual packaging cost

That sounds obvious, but packaging comparisons often make it surprisingly hard to see.

"Free Shipping" Does Not Mean Shipping Has No Cost

Corrugated shipping boxes are relatively lightweight, but they take up a lot of space.

That matters because carriers do not price shipments based only on what a package weighs on a scale. Dimensions, distance, service level, actual weight and dimensional weight can all influence shipping costs.

In simple terms, large lightweight items can still be expensive to transport because they occupy valuable space inside a truck.

Boxes are a perfect example.

That is why we do not think packaging buyers should make a supplier decision based on whether the website says "free shipping."

Shipping is not free.

Someone is paying for it.

The shipping cost may be shown separately, subsidized by the seller, incorporated into the box price, or recovered somewhere else in the transaction.

For the customer, the better question is:

What is my total delivered cost?

Shipping Costs Are Largely Driven by the Same Economics

There is no secret way to make a stack of corrugated boxes stop taking up space in a truck.

A shipment still has:

weight
dimensions
dimensional weight
origin and destination
shipping zone
carrier service
fuel costs
potential surcharges

Different suppliers may have different carrier agreements, warehouse locations and negotiated discounts, so freight will not be identical in every situation.

But the basic transportation economics remain.

If comparable boxes are traveling a comparable distance at a comparable size and weight, there is only so much any supplier can do to change the underlying carrier cost.

That is why the bigger opportunity may be the price of the box itself.

How CustomBoxes.io Is Working to Lower Shipping Costs

At CustomBoxes.io, our approach is not to pretend shipping disappears.

It is to reduce that cost wherever we reasonably can and make the total cost easier for customers to understand.

One of the ways we can do that is through volume.

As we ship more packaging, our combined shipping volume can give us additional negotiating power with carriers. Better volume economics may allow us to secure stronger shipping rates and pass some of those efficiencies through to customers.

Instead of treating every customer as if they were negotiating freight independently, we can use the scale of the larger CustomBoxes.io customer base.

That matters especially for smaller businesses that would be unlikely to generate comparable parcel or freight volume on their own.

We are also focused on tools that make packaging decisions easier. CustomBoxes.io offers custom shipping boxes with your logo, 3D box visualization, a Bulk Order Calculator and an ROI Calculator, among other tools designed to simplify packaging purchasing.

But freight is only one side of the equation.

Don't Compare Shipping. Compare the Total Price.

Consider two hypothetical suppliers.

Supplier A

Box price: $100
Shipping: $25
Total: $125

Supplier B

Box price: $125
Shipping: "Free"
Total: $125

Economically, those offers may be very similar.

The word free did not make transportation disappear.

Now imagine a supplier can provide comparable custom boxes at a materially lower box price while shipping remains roughly similar.

That is where the meaningful savings can happen.

CustomBoxes.io pricing can be roughly 50% less in some comparable custom-box scenarios, depending on box size, quantity, printing, material, shipping and other order specifications.

That claim should always be treated as a comparison, not a universal guarantee.

The right way to evaluate it is simple:

Compare the final delivered price for the same box specifications.

Not the advertised shipping promotion.

Not the starting unit price.

Not the biggest percentage on the homepage.

The total.

The Worst Packaging Expense May Be a Box That Does Nothing for You

There is another part of packaging cost that is easy to overlook.

What happens after you pay for the box?

Consider a simple example.

Blank box

Boxes: $100

Shipping to receive them: $25

Total packaging expense: $125

Marketing value generated by the exterior of the box: potentially very little.

You spent $125 because you needed something to ship the product in.

That may be necessary, but the package itself is doing only one job.

Custom branded box

Custom boxes: $100 to $200

Shipping: $25

Total packaging expense: $125 to $225

But now the same physical package can potentially do more.

It can carry your:

logo
website
QR code
reorder message
referral offer
social media handle
customer-support information
product-launch message
sustainability message

The custom box still costs money.

It does not automatically produce revenue.

But it creates the opportunity to get something back from a packaging expense you already had to make.

For a deeper look at how branded packaging compares to blank boxes on a cost-per-use basis, see our breakdown of why the cheapest box often costs more.

If You're Paying to Ship the Box Anyway, Make the Box Work Harder

This is the part of the packaging conversation we think businesses should consider more carefully.

A blank shipping box is almost entirely an operating cost.

A branded shipping box is an operating cost that can also function as a marketing surface.

That changes how the investment can be evaluated.

Instead of asking only:

"What does this box cost?"

Consider asking:

"What does this box cost after accounting for the value it may create?"

For example, a branded box could encourage:

repeat purchases
QR code scans
referrals
social sharing
branded searches
visits to a reorder page
subscription signups

None of those outcomes are guaranteed.

They need to be measured.

But if you are already paying to manufacture and transport the box, adding measurable branding can give that expense another purpose.

Think of Packaging as Cost Per Customer Touch

Most ecommerce businesses spend significant money trying to reach customers.

Paid social.

Search advertising.

Email.

Influencer marketing.

Direct mail.

Retargeting.

Then a customer finally orders something, and the business sends the product in a completely blank brown box.

That can be a missed opportunity.

The shipping box may be one of the few marketing surfaces that is almost guaranteed to reach an existing customer.

You already purchased it.

You already paid to transport it to your facility.

You already paid to send the order to your customer.

The question is whether that surface does anything beyond protecting the product.

If you are ordering consistently, a BoxFlow auto-shipping subscription can lock in your box specs and pricing so each reorder is handled automatically — one less thing to manage between shipments.

A Better Way to Compare Blank and Custom Boxes

Rather than comparing unit prices in isolation, businesses can use a more complete framework.

Cost factor	Blank box	Custom branded box
Box cost	$100 example	$100 to $200 example
Inbound shipping	$25	$25
Total packaging cost	$125	$125 to $225
Branding	No	Yes
QR/reorder opportunity	Limited	Yes
Customer marketing surface	Limited	Yes
Potential revenue offset	Limited	Possible

The phrase potential revenue offset is important.

We are not saying a custom box magically pays for itself.

We are saying it gives businesses an opportunity to measure whether packaging contributes value after the purchase.

A blank box generally offers much less opportunity to do that.

Dimensional Weight Still Matters

Businesses also need to pay attention to box size. To clarify, the higher volume you do with larger boxes means you'll need to more vs lower volume and small boxes.

Carriers frequently consider dimensional weight when calculating transportation costs.

A common dimensional-weight formula looks something like:

Length × Width × Height ÷ dimensional divisor

The exact carrier calculation can vary, but the principle is straightforward.

Shipping a box that is much larger than necessary may cost more because the shipment occupies more carrier capacity.

That means packaging optimization is not simply about ordering the cheapest box.

It is about finding a box that protects the product without unnecessarily increasing transportation cost.

Choosing from a range of standard-size custom shipping boxes — available in 11 sizes — makes it easier to match your product dimensions and avoid paying for unused space inside the box.

Right-sizing packaging can potentially help businesses reduce:

unused space
void fill
dimensional weight exposure
storage requirements
unnecessary material usage

It can also create a cleaner customer experience.

Shipping Cost Management Should Be Continuous

The industry information you shared makes another useful point.

When carrier pricing changes frequently, businesses cannot necessarily wait until their annual carrier negotiation to understand the impact.

A better question is:

When shipping pricing changes, how quickly do we know what it does to our costs?

If nobody notices until several months of invoices have accumulated, the business may have been operating with outdated assumptions the entire time.

For packaging buyers, the same thinking applies.

Review:

carrier charges
dimensional weight
order quantities
box dimensions
supplier freight
cost per delivered box
storage efficiency

regularly rather than once a year.

Small differences multiplied across thousands of shipments can become meaningful.

Don't Let "Free Shipping" Distract From Expensive Boxes

Imagine one supplier charges:

$2.00 per box + $0.50 shipping

Total: $2.50

Another charges:

$3.00 per box + FREE SHIPPING

Total: $3.00

Which supplier is cheaper?

The first one.

The shipping label on the invoice does not change the economics.

This is why we believe the packaging industry should be more transparent about the distinction between shipping price and total delivered price.

Customers do not pay their bills with marketing claims.

They pay the invoice total.

What Businesses Should Ask Before Ordering Shipping Boxes

Before comparing packaging suppliers, ask:

What is the total box price?
What is the shipping cost?
Are there setup, plate or tooling fees?
Is printing included?
Are the materials comparable?
Are the dimensions identical?
Is the quantity identical?
What is my delivered cost per usable box?
Can this packaging create measurable marketing value?
Can I reduce dimensional weight by changing the box size?

This makes comparison shopping much more useful. You can also use our comp shop and breakeven calculators to run the numbers side by side before you order.

The Goal Is Not the Cheapest Shipping Line Item

At CustomBoxes.io, we think the goal should be lower total packaging cost, not simply the smallest shipping number shown during checkout.

That means working on both sides of the equation.

Use growing shipping volume to pursue stronger carrier economics.

Pay attention to dimensional weight and box sizing.

Keep the underlying box price competitive.

Make freight transparent.

And whenever possible, make the packaging itself useful to the business.

Because if you already have to pay for a box and pay to move it, there is a strong argument for getting more value out of it.

The Bottom Line

You cannot make the physics of shipping disappear.

Boxes take up space.

Carriers charge to move them.

Weight, dimensions, distance and carrier pricing still matter regardless of which packaging company you use.

So instead of asking:

"Who says shipping is free?"

Ask:

"Who gives me the lowest total delivered cost?"

And then ask one more question:

"What does the box do for my business after I pay for it?"

A blank box may simply be an expense.

A custom box can potentially become an expense plus a customer touchpoint, branding opportunity and measurable marketing asset.

If the box has to make the trip anyway, we think it should work as hard as possible along the way.

FAQs

Is shipping really free when a packaging company advertises free shipping?

Not necessarily in an economic sense. The freight expense may be subsidized, incorporated into product pricing or recovered elsewhere. Buyers should compare the total delivered cost rather than the shipping line item alone.

Are shipping costs the same for every box supplier?

No. Different suppliers can have different negotiated carrier rates, production locations and fulfillment strategies. However, the same basic factors such as weight, dimensions, distance and carrier service still influence transportation costs.

Why are corrugated boxes expensive to ship?

Corrugated boxes can occupy significant carrier capacity even when they are relatively lightweight. Dimensional weight calculations may therefore affect shipping costs.

What is dimensional weight?

Dimensional weight is a method carriers can use to account for package size as well as physical weight. Larger packages may be billed at a higher effective weight depending on carrier rules.

Can custom shipping boxes help reduce overall packaging costs?

They can in some situations. Businesses should compare delivered box pricing, right-size packaging where possible and consider whether branded packaging creates measurable marketing or repeat-purchase value. Our guide on where to order affordable branded packaging covers what to look for when sourcing custom boxes.

Are CustomBoxes.io boxes really roughly 50% cheaper?

Pricing can be roughly 50% lower in some comparable custom-box scenarios, depending on dimensions, order quantity, printing, materials, freight and other specifications. Customers should compare equivalent products and final delivered cost rather than relying on a percentage claim alone.

Are branded shipping boxes worth it?

That depends on the business. Branded boxes can create additional customer impressions and may support QR scans, repeat purchases, referrals or brand recognition. Those outcomes should be measured rather than assumed.

What CustomBoxes.io tools can help with packaging decisions?

CustomBoxes.io offers tools including 3D box visualization, a Bulk Order Calculator and ROI Calculator to help businesses evaluate custom packaging options. If you prefer to order on a recurring schedule, explore the BoxFlow auto-shipping subscription to automate restocks.
