Monthly Cost to Run an Online Store: Full Breakdown

Ask ten store owners what they pay each month and you'll get ten different answers — and most of them are wrong, because they forgot half the bill. The true monthly cost to run an online store is rarely a single subscription. It's a stack: platform fees, app subscriptions, payment processing, hosting, design tweaks, and a dozen small charges that quietly add up. This guide breaks down every line so you can see exactly where your money goes and where you're overpaying.

What makes up the monthly cost to run an online store

The cost of running an online store splits into five buckets. Some are fixed and predictable. Others scale with your sales, which is exactly why owners underestimate them. Here's the full map.

• Platform subscription — the base fee you pay to host and operate the store (Shopify, WooCommerce hosting, BigCommerce, etc.).
• Apps and plugins — the extra features your platform doesn't include by default: abandoned cart, reviews, loyalty, email.
• Payment processing fees — a percentage of every sale, plus a flat fee per transaction.
• Marketing and email — ad spend, email tools, SEO software, and content.
• Maintenance and people — developers, designers, security patching, and your own time.

When people ask how much does it cost to maintain an ecommerce website, they usually only count the first bucket. The other four are where the surprises live. A $39 plan can easily become a $400 monthly bill once the stack is complete.

Platform fees: how much does Shopify cost per month?

Shopify costs $39 per month on the Basic plan, $105 on Shopify, and $399 on Advanced when billed monthly. Annual billing trims those numbers. The Plus tier — built for high-volume sellers — starts around $2,300 per month. But the plan fee is just the entry ticket.

You can confirm current pricing on the official Shopify pricing page. The catch isn't the headline number — it's everything Shopify doesn't include. Abandoned cart recovery on the cheapest tier, real customer Q&A, wishlists, and advanced product pages all require paid apps on top.

Other platforms price differently but follow the same pattern:

• WooCommerce — the plugin is free, but you pay $30–$100/month for hosting, plus plugins, plus a developer when things break.
• Wix and Squarespace — $17–$159/month, with most serious commerce features behind higher tiers.
• BigCommerce — $39–$399/month, with sales-volume thresholds that force upgrades.

App and plugin costs: the hidden ecommerce expenses

This is where monthly ecommerce expenses spiral. Around 87% of Shopify stores run apps, and the average store stacks about six of them. Each one carries its own monthly fee — and they don't talk to each other cleanly.

Here's a realistic app stack for a store doing modest volume:

Feature	Typical monthly cost
Abandoned cart / email marketing (Klaviyo)	$20–$150
Product reviews	$15–$50
Loyalty and rewards	$25–$200
Wishlist	$10–$30
Upsell / cross-sell	$20–$60
SEO and page speed tools	$20–$50
Total app spend	$110–$540/month

Beyond the dollar cost, every plugin you bolt on slows your store down and adds a security surface you now have to maintain. Plugin conflicts are a leading reason stores break — and roughly 20% of WooCommerce stores shut down within six months largely because the ecommerce maintenance cost and upkeep burden becomes unmanageable.

The smarter move is a platform where these features come built in. Rovela includes 100+ features — abandoned cart, wishlist, loyalty, reviews, Q&A, automations, and integrations like Klaviyo and Meta — in a single flat subscription with no per-app billing. That alone saves the average merchant $5,000+ per year on plugin costs.

Payment processing fees every store pays

Payment processing fees for ecommerce typically run 2.9% plus $0.30 per transaction. On $20,000 in monthly sales, that's roughly $580 — every month, scaling directly with revenue. These fees are unavoidable, but the structure varies.

Stripe and PayPal both publish their standard rates openly; you can check current numbers on the Stripe pricing page. Watch for two extra charges that catch sellers off guard:

• Transaction fees on top of processing — Shopify charges an additional 0.5%–2% if you don't use Shopify Payments. That's a tax on choosing your own processor.
• Cross-border and currency conversion fees — often 1%–2% extra on international orders.

If you sell internationally or run high volume, these add up fast. A platform that charges no commission on your sales — only your processor's standard rate — keeps more margin in your pocket. That difference compounds into thousands per year at scale.

The full picture: realistic monthly cost scenarios

Let's add the buckets together for three common store profiles. These ranges reflect online store running costs in 2026 for owners selling physical products.

Cost area	New store ($2K/mo sales)	Growing store ($20K/mo sales)
Platform subscription	$39	$105
Apps and plugins	$60	$300
Payment processing	$68	$580
Email and marketing tools	$30	$200
Domain and security	$5	$15
Design / developer help	$0–$100	$200–$1,000
Estimated total	$200–$300	$1,400–$2,200

Two patterns jump out. First, the platform subscription is the smallest line on the bill — usually under 10% of the total. Second, ecommerce ongoing costs scale with revenue, so the better you do, the more the fragmented-stack model costs you. Growth shouldn't mean paying a bigger toll on every dollar.

This is the structural problem with the typical setup: you assemble a stack, and each new feature is a new monthly charge, a new login, and a new thing that can break. The cost of running an online store balloons not because any single tool is expensive, but because there are so many of them.

How to cut your online store running costs

You don't have to accept the bloated stack. Here are practical moves that lower your monthly bill without hurting sales.

1. Audit your apps quarterly. List every subscription and what it actually does. Cancel anything you haven't touched in 90 days — most stores find two or three dead apps.
2. Consolidate overlapping tools. If three apps each do part of email, reviews, and upsells, one platform that covers all three is cheaper and faster.
3. Negotiate or switch processors. If you're paying extra transaction fees on top of processing, moving to native payments removes that surcharge instantly.
4. Choose built-in over bolt-on. Features included by default cost nothing extra and don't slow your site. Every plugin you remove is a recurring saving and a speed gain.
5. Count your own time. Hours spent fixing plugin conflicts have a real cost. Merchants on integrated platforms report recovering about two hours per week on admin work.

This is the case for an all-in-one approach. Rather than paying a base fee plus six apps plus surcharges, an AI-built store from Rovela ships with the full storefront, Stripe checkout, admin dashboard, analytics, and those 100+ features for one flat price — and the store runs on standard Next.js code you can download and own outright. Merchants typically see +15% revenue and +22% margins after switching, partly because the site stays fast no matter how many features are active. You can compare what's included against your current stack on the Rovela pricing page.

Frequently asked questions about ecommerce costs

How much does it cost to maintain an ecommerce website?

Maintaining an ecommerce website typically costs $200–$500 per month for a small store and $1,000–$3,000+ for a growing one, once you include platform fees, apps, payment processing, security, and developer time. Maintenance is the largest hidden line for self-hosted stores like WooCommerce.

What's the cheapest way to run an online store?

The cheapest sustainable option is a platform that bundles features into one flat fee, so you avoid stacking paid apps and extra transaction fees. Free plugins like WooCommerce look cheap but add hosting, maintenance, and developer costs that often exceed an all-in-one subscription.

Do payment processing fees ever go away?

No. Payment processing fees are charged by the card networks and processors, so every store pays roughly 2.9% + $0.30 per transaction. What you can eliminate is the extra platform surcharge some providers add when you don't use their native payments.

The headline subscription is never the real number. The true monthly cost to run an online store is the whole stack — platform, apps, processing, marketing, and maintenance — and for most owners the apps and fees dwarf the base plan. Map your own five buckets, kill the dead subscriptions, and favor built-in features over bolt-ons. If you'd rather skip the stack entirely, Rovela builds a complete store from a plain-language conversation with every feature included for one flat price — see how the math compares on the pricing page or read more on the Rovela blog.
