Are Shipping Costs Quietly Killing Your Shopify Margins?

You set your shipping rate to $5.99 two years ago when you launched. You haven't changed it since. Meanwhile, USPS raised rates twice, your boxes got more expensive, and you started using bubble wrap because customers complained about damaged items.

Last month, your actual shipping cost per order was $8.42. You charged $5.99. That's $2.43 per order you're quietly giving away. At 250 orders per month, that's $607.50. Over a year: $7,290. You could hire a part-time assistant for that money. Instead, it's disappearing into the shipping gap.

The shipping gap

This is the difference between what you charge customers and what you actually pay. It's the single most overlooked cost in e-commerce. And almost every merchant has one, because carrier rates go up every January but your shipping charge stays the same. Calculate yours →

What shipping actually costs in 2026

Add it all up. If the total is more than what you charge, you have a shipping gap. And it's bigger than you think because the "small stuff" — boxes, tape, labels — adds $1-4 per order that most merchants never count.

What to do about it

Three options: raise your shipping charge (simplest), raise product prices and offer "free" shipping (works if your margins can absorb it), or switch to Shopify Shipping and get up to 88% off USPS rates (the biggest quick win for most stores). Whatever you choose, stop pretending the gap doesn't exist. It does. And it's costing you thousands.
