You're staring at your Shopify invoice — again — and doing the math in your head. Between the monthly plan, transaction fees, and three apps you can't live without, you're pushing $400 a month before you've sold a single item. A friend mentions WooCommerce or Medusa, and suddenly self-hosting sounds like the obvious move.
But is it actually cheaper? Sometimes, yes. Sometimes, surprisingly no. The honest answer is that self-hosted e-commerce platform costs are more spread out and less predictable than a SaaS subscription — and that catches a lot of store owners off guard.
Let's walk through every cost layer so you can build a real budget, not a wishful one.
What "Self-Hosted" Actually Means (and Why It Changes the Math)
When you self-host, you run the software on infrastructure you control — a VPS, a managed cloud server, or even a dedicated box. You own the code, the data, and the uptime responsibility. Platforms in this category include WooCommerce (WordPress), PrestaShop, Magento Open Source, and newer headless options like Medusa.js or Sylius.
The software itself is usually free or open-source. That's the headline number people remember. But the software is only one slice of the pie. Here's how the full cost picture actually breaks down.
Hosting: The Bill That Grows With You
Hosting is your biggest variable. A small WooCommerce store on a shared host might cost $10–$15 a month. That's fine for a brand-new store doing under 500 orders a month. But shared hosting buckles under real traffic, and a slow store loses sales — studies consistently show a 1-second delay in page load can cut conversions by 7%.
Once you graduate to a managed WordPress host (Kinsta, WP Engine, Cloudways), you're looking at $30–$100 a month for a mid-tier plan. For a Magento Open Source store, a properly spec'd cloud server on AWS or DigitalOcean runs $80–$250 a month, and that's before you add a CDN.
Headless setups — where your frontend is decoupled from the commerce backend — can split costs across a Node server for the API and a static frontend on Vercel or Netlify. The frontend hosting is often free or near-free at low traffic, but the backend server still needs resources. Budget $50–$150 a month for a modest headless stack.
Quick benchmark: A store doing $30K/month in revenue should budget at least $80–$150/month just for reliable hosting. Anything less and you're gambling with uptime.
Domain, SSL, and CDN: The Boring Essentials
These are small but real:
- Domain: $10–$20 a year for a .com. Non-negotiable.
- SSL certificate: Free via Let's Encrypt on most modern hosts, but some managed hosts bundle it. Budget $0–$100/year depending on your setup.
- CDN: Cloudflare's free tier handles most small stores fine. If you need advanced image optimization or edge caching, Cloudflare Pro is $20/month. BunnyCDN is another solid option at roughly $1 per 100 GB of bandwidth — very affordable unless you're shipping huge product images at scale.
Total here: $10–$50/month for most stores, less if you're lean about it.
The Plugin and Extension Tax
This is where self-hosted costs quietly creep up, and it's the number one thing new store owners underestimate.
WooCommerce itself is free. But a production-ready WooCommerce store almost always needs:
- A premium theme: $50–$200 one-time, or $15–$30/month for a subscription theme
- A page builder (Elementor Pro, Divi): $50–$100/year
- Advanced shipping rules plugin: $80–$200/year
- Subscription or membership plugin (if relevant): $200–$300/year
- A serious SEO plugin beyond the free Yoast tier: $100/year
- Product filter and search: $100–$300/year
- A backup solution: $50–$100/year
Add those up and you're easily at $600–$1,200/year in plugins alone — $50–$100/month. Sound familiar? That's roughly what you were paying in Shopify apps.
PrestaShop and Magento Open Source have their own module marketplaces with similar dynamics. A solid Magento extension for B2B pricing or advanced product configuration can run $300–$800 as a one-time purchase, but many are now subscription-based at $30–$80/month each.
The honest question to ask yourself: how many paid extensions does your store actually need to function? List them out before you migrate. Price every single one.
Developer and Maintenance Costs: The Real Wildcard
Here's the cost that SaaS platforms absorb for you and self-hosting hands back to you: technical maintenance.
On Shopify, security patches, server updates, and core upgrades happen automatically. On a self-hosted platform, that's your job — or your developer's job.
If you're technical, you might handle routine updates yourself. But even confident store owners usually need a developer for:
- Initial setup and theme customization: $1,500–$5,000 one-time for WooCommerce; $5,000–$20,000+ for Magento
- Ongoing maintenance retainer: $200–$800/month depending on complexity
- Emergency fixes (a plugin conflict breaks checkout the night before a sale): $150–$300/hour
A realistic annual developer budget for a self-hosted WooCommerce store that isn't a pure DIY project: $3,000–$8,000/year, or $250–$670/month.
For Magento Open Source, double those numbers at minimum. Magento is powerful, but it's not a platform you run without dedicated technical resources. Most stores that migrate to Magento and regret it cite developer costs as the reason.
Payment Processing: Same as Everywhere, Mostly
Good news: payment processing costs are roughly the same whether you're self-hosted or on SaaS. Stripe, Square, and PayPal charge 2.9% + $0.30 per transaction regardless of your platform. Some self-hosted setups let you negotiate lower rates with direct payment processors once you hit $50K+/month in volume — that's a genuine advantage over SaaS platforms that lock you into their own payment tools.
One thing to watch: some WooCommerce payment gateway plugins charge a small monthly fee ($5–$30) on top of transaction fees. Read the fine print.
A Real-World Cost Example: WooCommerce at $25K/Month Revenue
Let me put concrete numbers on a mid-sized store. Say you're running a WooCommerce store doing about $25,000/month in revenue — roughly 200–300 orders.
| Cost Item | Monthly Estimate |
|---|---|
| Managed WordPress hosting (Cloudways) | $80 |
| CDN (Cloudflare Pro) | $20 |
| Domain + SSL | $2 |
| Plugin subscriptions (annualized) | $75 |
| Developer retainer (light) | $300 |
| Payment processing (2.9% + $0.30) | $750 |
| Total | ~$1,227/month |
For comparison, a Shopify Advanced plan at the same volume would run roughly $399/month for the platform, plus 0.5% transaction fee if you're not on Shopify Payments ($125), plus apps ($100–$200). Call it $650–$750/month before payment processing. Add Stripe at the same rate and you're at $1,400–$1,500/month.
So in this scenario, WooCommerce is modestly cheaper — maybe $150–$250/month. That's real money over a year ($1,800–$3,000), but it's not the dramatic savings people expect, and it comes with more of your time and attention invested in the infrastructure.
When Self-Hosting Actually Saves You Money
Self-hosted platforms tend to win on cost when:
- You're technical (or have a technical co-founder). If you can handle updates, troubleshoot plugin conflicts, and do basic server management yourself, you cut out the biggest cost line entirely.
- You need heavy customization. A SaaS platform charges you for every custom feature through apps. A self-hosted platform lets you build exactly what you need — once — and own it.
- You're scaling past $100K/month. At higher volumes, the percentage-based fees on SaaS platforms add up fast. Self-hosting with a direct payment processor can save thousands per month.
- You sell in a niche with specific compliance needs — certain industries need data residency or custom checkout flows that SaaS platforms simply won't support.
Three Things You Can Do Today Before Committing
If you're seriously considering a move to a self-hosted platform, here are three concrete steps to take right now:
- Audit your current app and plugin spend. List every tool you pay for and find the self-hosted equivalent. Price it. This single exercise will tell you whether migration makes financial sense.
- Get a developer quote for setup. Post your requirements on Upwork or a platform-specific forum and get 2–3 quotes for initial setup. Real numbers beat guesses every time.
- Spin up a test instance. WooCommerce on a $6/month DigitalOcean droplet takes about an hour to set up. Run it for 30 days and get a feel for the maintenance overhead before you commit your live store.
None of these steps cost much, and all three will give you data instead of assumptions.
The Bottom Line on Self-Hosted E-Commerce Platform Costs
Self-hosted e-commerce platform costs are real, layered, and easy to underestimate if you only look at the "free software" headline. Hosting, extensions, developer time, and ongoing maintenance add up to somewhere between $500 and $2,000+ per month for a serious store — a range that overlaps heavily with what you'd pay on a well-configured SaaS plan.
That doesn't mean self-hosting is wrong for you. For the right store — technical founder, custom requirements, high volume — it's genuinely the smarter financial choice. But go in with a full budget, not just the server bill. You might also want to review how to harden SSH on Ubuntu if you're managing your own servers, as security is another often-overlooked cost when things go wrong.
Your next step: build a 12-month cost projection using the categories above. Plug in your real numbers. Then compare it to what you're paying now. That spreadsheet will tell you more than any blog post can.
You've got this.
