The Real Cost to Run an Online Store in 2026

Ask ten merchants what it costs to run an online store and you'll get ten different answers — most of them wrong. The cost to run an online store isn't a single subscription line. It's a stack: platform fees, apps, payment processing, hosting, design, maintenance, and the hours you spend wrestling with all of it. Add those up and the number that looked like $39 a month often lands closer to $500 or more. This guide breaks down every layer so you know exactly what you'll pay before you commit — and where the money quietly disappears.

How much does an online store cost to run?

A realistic online store monthly cost in 2026 runs between $150 and $1,500 for a small-to-midsize merchant, once you count platform fees, apps, payment processing, and maintenance. The base subscription is rarely more than 20% of that total — the rest hides in add-ons and transaction cuts.

That range surprises people because platform marketing leads with the cheapest possible number. A "$29/month" plan sounds affordable until you need abandoned cart recovery, a wishlist, real product reviews, and email automation — none of which come included. Each one is a separate app with its own monthly bill.

So when someone asks how much does an online store cost, the honest answer is: it depends entirely on what's bundled versus what you bolt on. A platform that includes essentials charges more upfront but costs far less in total. A cheap base plan with a long app list is usually the expensive option in disguise.

The rest of this article walks through every cost category, gives you real 2026 numbers, and shows you how to estimate your own total before you build.

The true cost of an online store, layer by layer

To understand the true cost of an online store, you have to separate it into its real components. Here's where every dollar actually goes.

1. Platform subscription

This is the line everyone quotes. Shopify's published plans run from $39 to $399 per month, with enterprise tiers climbing into the thousands. WooCommerce itself is free, but you pay for hosting — typically $30 to $100 a month — plus the time to manage it. Wix and Squarespace sit between $17 and $399.

The subscription buys you a storefront and checkout. On most platforms, it does not buy you the features that actually grow revenue. That's the next layer, and it's where budgets blow up.

2. Apps and plugins

Here's the number most guides skip: 87% of Shopify stores run apps, averaging six per store. Those apps cost $50 to $200 a month combined, and they're not optional extras — they're things every serious store needs.

Abandoned cart recovery. Wishlist. Loyalty points. Customer reviews. Advanced product pages. Email and SMS automation. On app-based platforms, each is a recurring subscription. The "ecosystem" sounds like a feature; on your invoice, it's a tax.

3. Payment processing

Every sale gets a cut taken. Standard card processing is roughly 2.9% + $0.30 per transaction. Some platforms add their own commission on top if you don't use their in-house payment tool — anywhere from 0.5% to 2% extra per sale.

On $10,000 in monthly sales, processing alone is around $300. The platform's extra commission can add $50 to $200 more. These ecommerce store expenses scale with success, so the more you sell, the more they quietly take.

4. Theme, design, and development

Premium themes cost $100 to $400 one-time. Real customization — the kind that makes your store look like a brand rather than a template — means hiring a developer at $50 to $150 an hour, or an agency on a $500 to $5,000 monthly retainer.

5. Maintenance and security

Online store maintenance cost is the layer nobody budgets for. On self-hosted setups like WooCommerce, you own updates, plugin conflicts, security patches, and backups. When something breaks at 2 a.m. during a sale, it's your problem. Roughly 20% of WooCommerce stores shut down within six months, largely from this burden.

Online store monthly cost: a real-world comparison

Numbers in isolation don't help much. Here's what the cost of running an ecommerce store looks like across the main platforms for a typical small store doing about $10,000 a month in sales.

Cost category	Shopify	WooCommerce	Wix / Squarespace
Base platform	$39–$399/mo	$0 (open source)	$27–$399/mo
Hosting	Included	$30–$100/mo	Included
Apps / plugins	$50–$200/mo	$40–$150/mo	$20–$120/mo
Payment fees (on $10k)	~$300 + commission	~$300	~$300
Maintenance / dev	$0–$500/mo	$100–$1,000/mo	$0–$300/mo
Realistic monthly total	$400–$1,400	$470–$1,550	$370–$1,100

The pattern is clear. A low base price does not mean a low total. WooCommerce starts at zero and often ends up the most expensive once you price in hosting, plugins, and the developer hours to hold it together.

This is the heart of any honest ecommerce platform fees comparison: the subscription is the smallest part of the bill. The apps, the commissions, and the maintenance are where the real money lives — and where merchants consistently underestimate.

The hidden ecommerce store expenses nobody warns you about

Beyond the obvious lines, several costs creep in slowly. They don't show up on a pricing page, but they're real, and they add up fast.

• Your time. Hours spent installing apps, debugging conflicts, and updating plugins have a dollar value. Merchants on bloated stacks lose around two hours a week to admin work that better tooling handles automatically.
• Speed penalties. Every app you stack slows your store down. Slow mobile load times hurt both SEO rankings and conversion rates — meaning you pay for traffic that bounces before it buys.
• Plugin conflicts. Two apps that each work fine can break each other. Diagnosing that costs developer hours or lost sales while your checkout misbehaves.
• Re-platforming. Outgrow your platform and migrating is expensive — data exports, redesigns, SEO recovery, and weeks of disruption. The cost of switching is itself a hidden expense of choosing wrong early.
• Security and compliance. On self-managed setups, a missed patch can mean a breach. The cleanup, not to mention the trust damage, dwarfs any subscription saving.

The U.S. Small Business Administration's guidance for small businesses stresses building a realistic operating budget — and for online retailers, these invisible lines are exactly the ones that wreck a budget built only on the sticker price.

How to estimate and lower your store's running cost

You don't need a finance degree to forecast this. Work through these steps and you'll have a realistic figure for what running your store will actually cost.

1. Start with the base plan you'll realistically need — not the cheapest tier, the one that fits your catalog size and sales volume.
2. List the features you actually need to sell: cart recovery, reviews, wishlist, email automation, loyalty. Price each as a separate app if your platform doesn't include it.
3. Calculate payment fees on your expected monthly sales at 2.9% + $0.30, then add any platform commission.
4. Add a maintenance buffer — even managed platforms need occasional help. Self-hosted ones need a lot.
5. Value your own time at an hourly rate and add the admin hours the setup will demand each week.

Once you've got that number, here's how to bring it down:

• Choose included over add-on. A platform where essentials come built in almost always beats a cheap base plan plus a dozen paid apps. Run the full math, not just the headline price.
• Avoid sales commissions. Flat pricing beats percentage cuts the moment you start growing. A 1% commission on $50k a month is $500 — every month, forever.
• Keep the stack lean. Fewer moving parts means fewer conflicts, faster load times, and lower maintenance. Speed is free revenue.
• Own your code. Platforms that let you download and own your store — rather than locking you into a proprietary system — protect you from forced upgrades and brutal migration costs later.

This is the logic behind Rovela, which was built by operators who scaled stores past $15M in sales and ran the team behind 400,000+ PrestaShop merchants. Instead of a low base price plus an endless app list, you get 100+ features included by default — abandoned cart, wishlist, loyalty, reviews, Q&A, automations, and integrations — for one flat subscription, with no commission on your sales. Merchants typically save over $5,000 a year on platform and plugin costs and recover about two hours a week of admin time. You can see exactly what's bundled on the pricing page.

What does it really cost? The honest answer

So, how much does ecommerce cost to run? For a small store, plan on $150 to $500 a month all-in if you keep your stack disciplined — and $500 to $1,500 or more once apps, commissions, and maintenance pile up on a traditional platform.

The single biggest lever is whether your features come included or bolted on. That one choice swings your total cost more than any other decision you'll make. A $39 plan with $400 of apps is a $440 store. A flat plan with everything included is exactly what it says.

Before you commit to any platform, build the full picture: base fee, apps, payment cuts, maintenance, and your own time. The cheapest sticker price is rarely the cheapest store. If you'd rather skip the app math entirely and run a fast, fully-featured store for one predictable price, Rovela builds and runs your store from a single conversation — and you can browse more breakdowns like this one on the Rovela blog.
