Shopify's Basic plan costs $39/month. That number is on every pricing page, every comparison article, every "how to start an online store" guide. It's also the least useful number in ecommerce. Shopify's hidden costs — payment processing, app subscriptions, transaction surcharges, and international fees — push the real number to $300–$900/month depending on your revenue.

A merchant doing $10,000/month on the Basic plan pays closer to $489/month in total platform costs. That's not a rounding error. It's the difference between a profitable store and one that bleeds cash for six months before the founder figures out why.

Your Subscription Fee Is the Smallest Line Item

Shopify offers five plans in 2026: Starter ($5/month), Basic ($39/month), Grow ($105/month), Advanced ($399/month), and Plus (from $2,300/month). Most merchants land on Basic or Grow.

The subscription gets you the platform — hosting, store builder, basic analytics, a few staff accounts. But it's typically 10–15% of your total monthly Shopify spend. The rest comes from fees that scale with your revenue, which means the more you sell, the more you pay in absolute dollars.

That's not necessarily a bad thing. Percentage-based fees mean your costs grow with your business, not ahead of it. But you need to know the percentages to forecast your margins accurately.

Payment Processing Takes 2.9% of Every Sale (At Minimum)

On Shopify's Basic plan using Shopify Payments, you pay 2.9% + 30¢ per online transaction. On a $50 order, that's $1.75. On a $100 order, $3.20. Those numbers don't sound alarming until you multiply them by hundreds of orders per month.

Here's how it breaks down by plan:

Basic: 2.9% + 30¢ online, 2.6% + 10¢ in-person
Grow: 2.7% + 30¢ online, 2.5% + 10¢ in-person
Advanced: 2.5% + 30¢ online, 2.4% + 10¢ in-person

The 30¢ fixed fee per transaction matters more than most merchants realize. On a $20 order, the fixed fee alone is 1.5% of the sale — on top of the percentage rate. Stores with lower average order values get hit harder by this math.

If you don't use Shopify Payments and process through PayPal, Stripe, or a local gateway, Shopify adds an extra surcharge: 2% on Basic, 1% on Grow, 0.6% on Advanced. Combined with your gateway's own processing fee (typically 2.9% + 30¢), you could be paying close to 5% per transaction on the Basic plan. That's $50 gone on every $1,000 in sales before you've counted anything else.

International Sales Add Another 3% You Didn't Budget For

Selling to customers outside your home country triggers two additional fees through Shopify Payments:

International card fee: +1.5% on top of your standard processing rate
Currency conversion fee: +1.5% if the customer pays in a different currency than your payout currency

These stack. A Basic plan merchant selling a $100 product to an international customer paying in a foreign currency pays 2.9% + 1.5% + 1.5% + 30¢ = $6.20 in processing fees. That's 6.2% of the sale.

If international orders make up 20–30% of your revenue, this isn't a rounding error. It's a cost center you need to price into your margins or absorb knowingly.

Apps Cost $60–$120/Month and Most Merchants Can't Avoid Them

Shopify's core platform is intentionally lean. Email marketing, advanced analytics, review collection, upsells, SEO tools, shipping rate calculators — most of these require third-party apps. And those apps charge monthly subscriptions.

The average Shopify store spends $60–$120/month on paid apps. Stores with more complex operations (multiple sales channels, B2B, subscription products) often spend $200–$500/month. About 87% of Shopify merchants use apps, with an average of six installed per store.

A typical app stack for a growing store might look like this:

Email marketing (Klaviyo, Omnisend): $20–$60/month
Reviews (Judge.me, Loox): $15–$30/month
SEO or page builder: $10–$30/month
Upsell or cross-sell app: $15–$30/month
Shipping or fulfillment app: $10–$30/month

That's $70–$180/month before you add anything specialized. And most apps charge more as your order volume grows — their pricing tiers scale with usage, just like Shopify's processing fees.

The fix isn't to avoid apps entirely. It's to audit your app stack quarterly. Check which apps you're actually using, which features overlap, and whether a single app could replace two or three. Consolidating from six apps to four can save $40–$80/month without losing functionality.

Shopify's Hidden Costs Beyond Fees: Returns, Chargebacks, and Themes

Some costs don't show up on Shopify's pricing page because they're not Shopify's fees — they're the cost of running an online store on any platform. But they still eat your margin.

Returns: Processing a single return costs 20–65% of the item's original value. That includes return shipping, inspection, repackaging, and the processing fee you already paid on the original sale (which you don't get back). A store with a 15% return rate is losing a meaningful chunk of gross margin to reverse logistics.

Chargebacks: When a customer disputes a charge, Shopify bills a $15 dispute fee regardless of the outcome. The average merchant loses about 55% of chargeback disputes. Even when you win, you've spent time gathering evidence and the $15 fee still applies.

Theme costs: Free themes work, but most growing stores eventually buy a premium theme ($250–$400 one-time) or hire a developer for customizations ($500–$5,000 depending on scope). Theme updates from Shopify can also break custom code, creating recurring maintenance costs.

The Real Math at Four Revenue Tiers

Here's what a Shopify store actually costs per month at different revenue levels, assuming Shopify Payments, a domestic-only customer base, and a moderate app stack:

$5,000/month revenue (Basic plan, ~$50 AOV, ~100 orders)

Subscription: $39
Payment processing (2.9% + 30¢ × 100): $175
Apps: $70
Total: ~$284/month (5.7% of revenue)

$10,000/month revenue (Basic plan, ~$50 AOV, ~200 orders)

Subscription: $39
Payment processing (2.9% + 30¢ × 200): $350
Apps: $100
Total: ~$489/month (4.9% of revenue)

$25,000/month revenue (Grow plan, ~$60 AOV, ~417 orders)

Subscription: $105
Payment processing (2.7% + 30¢ × 417): $800
Apps: $150
Total: ~$1,055/month (4.2% of revenue)

$50,000/month revenue (Advanced plan, ~$70 AOV, ~714 orders)

Subscription: $399
Payment processing (2.5% + 30¢ × 714): $1,464
Apps: $250
Total: ~$2,113/month (4.2% of revenue)

Notice the pattern: total platform costs as a percentage of revenue decrease as you grow, but the absolute dollar amounts climb fast. A $50K/month store is sending over $2,100 back to Shopify and app providers every month.

Five Ways to Reduce Your Total Shopify Costs

1. Use Shopify Payments. This eliminates the 0.6–2% third-party gateway surcharge. For a $10K/month store on Basic, that's $200/month saved by switching from PayPal to Shopify Payments as your primary processor.

2. Upgrade your plan at the right time. If you're doing $15K+/month on Basic, the lower processing rates on Grow (2.7% vs 2.9%) save you more than the $66/month price difference. Run the math: $15,000 × 0.2% = $30/month in processing savings. At $25K/month, the savings exceed the upgrade cost.

3. Pay annually. Shopify offers roughly 25% off on annual billing. That turns the Basic plan from $39/month to about $29/month — saving $120/year for the same features.

4. Audit your apps quarterly. Uninstall apps you installed "to try" three months ago. Check for feature overlap — your email app might already do the pop-ups you're paying a separate app for. Look for apps that consolidate multiple functions into one subscription.

5. Factor processing fees into your pricing. If you're paying 3.2% in processing fees, your product margins need to account for that. A product with a 40% gross margin actually has a 36.8% margin after processing. Price accordingly from the start rather than discovering the gap later.

Know the Number Before It Surprises You

Shopify isn't expensive for what it provides. Hosting, security, payment infrastructure, a global CDN, and a platform that handles millions in transactions — $39/month for that is a genuine bargain. The issue isn't that Shopify costs too much. It's that the real number is 3–5x the sticker price, and most merchants don't discover that until they're already committed.

Open your Shopify admin, go to Settings → Billing, and add up your last three months of charges. Then add your app subscriptions. That's your real platform cost. If it's higher than you expected, start with the five cuts above — most stores can save 15–20% without changing anything about how they sell. Once you know your platform costs, run a full unit economics audit to see whether your store is actually profitable after all costs.
