How our ecommerce website cost calculator works
The ecommerce website cost calculator above turns a few answers about your project into a realistic budget range. It uses the same factors we use when scoping real projects, weighted by the effort they typically add.
Choose your platform, design approach, approximate catalog size, integrations and special features. The calculator then places your project within our standard price bands. It is a planning tool, not a quote: an exact figure needs a short discovery conversation.
What does an ecommerce website cost in 2026?
Most ecommerce builds fall into three bands. Where your project lands depends on complexity, not just platform.
- From around $15,000: our smallest engagements, such as focused builds with limited customization.
- $25,000–$60,000: specialized custom stores with tailored design, integrations and custom features.
- $60,000–$150,000+: complex headless enterprise builds and multi-region B2B platforms.

Ecommerce website cost factors explained
Five or six factors drive almost all of the variation in ecommerce budgets. The table shows how each one affects cost.
| Cost factor | Lower effort | Higher effort |
|---|---|---|
| Platform | Hosted platform with a customized theme | Headless, Magento or fully custom build |
| Design | Adapted design system | Fully custom UX research, prototypes and UI |
| Catalog | Hundreds of simple products | Tens of thousands of SKUs, variants or configurators |
| Integrations | Payments and shipping only | ERP, CRM, PIM, punchout and marketplaces |
| B2B features | None | Company accounts, contract pricing, approvals, RFQ |
| Data migration | New store, little data | Large order, customer and URL history from a legacy platform |
| Regions | One store, one currency | Multiple regions, languages and currencies |
How to get the most accurate estimate from the calculator
The more realistic your inputs, the more useful the range. A few tips:
- Count integrations you actually need at launch, not every tool you might add later.
- Estimate SKUs including variants if each variant has its own price or stock.
- Select B2B features if any customers need their own prices or payment terms.
- Include migration if you have existing customers, orders or ranking URLs to preserve.
- Run it twice, once for a lean launch and once for your full vision, to see the spread.
Why ecommerce costs vary so much
Two stores on the same platform can differ by tens of thousands of dollars because of what sits behind the storefront. A branded Shopify store with standard checkout is a very different project from a Shopify Plus build with ERP-synced B2B pricing.
That is why we focus on scope, not hourly rates. If your needs go beyond what platforms offer, our custom ecommerce website cost breakdown explains when custom development pays off.
From calculator estimate to fixed-price quote
After you have a range, the next step is a short discovery conversation. We confirm requirements, flag risks and turn the range into fixed-price milestones following our ecommerce website development process. You own 100% of the code, and a mutual NDA is available.
If you are still weighing platforms, an ecommerce consulting services engagement can settle that question before you commit to a build.
