Website Scope Complexity Estimator
Website scope is shaped by unique templates, content migration, integrations, locales, custom workflows, accessibility and review—not page count alone. This tool returns complexity points rather than a quote.

What this estimator is for
Two websites with the same number of pages can differ hugely in effort. A 40-page site built from three templates is often simpler than a 15-page site with a booking system, a CRM connection and two languages. This estimator helps you see where your project's complexity comes from, so you can brief agencies clearly and compare quotes on a like-for-like basis.
It returns complexity points, not a price. Use it before you request quotes, or to sense-check a quote you already have.
The four inputs
Unique page templates. A template is a distinct page layout: home, service page, blog post, product page, location page, contact page. Count layouts, not pages. Fifty blog posts share one template.
External integrations. Systems the website must connect to: CRM, payment gateway, booking software, ERP or inventory, email marketing, WhatsApp, maps or review feeds. Each one needs setup, testing and ongoing maintenance.
Complete language versions. Each full language version adds translation, review, layout checks and SEO work such as hreflang tags. Count 1 for an English-only site.
Custom interactive workflows. Features that go beyond content pages, such as calculators, quote builders, multi-step forms, member areas, dashboards or configurators.
How the score is calculated
The estimator adds weighted points: 3 per unique template, 6 per integration, 8 per language version beyond the first and 7 per custom workflow. The weights reflect that integrations and workflows usually take more effort than an extra template. They are a planning convention, not a measured cost.
Reading your result
A higher score means more discovery, design and testing time before launch, and usually a longer build. Change one input at a time to see which factor drives your score; that's often where simplifying a first release saves the most. Content migration, accessibility requirements, approvals and hosting also affect cost but aren't scored here, so mention them in your brief. Our guide on what affects website development cost covers these.

Frequently asked questions
Does a higher score mean a more expensive website?
Generally, more complexity means more work, but price also depends on design, content and who builds it. A real quote needs a scoping conversation.
What counts as a template?
A distinct page layout. Pages that share a layout with different content count once.
Should I include future features?
Run it twice, once for the first release and once for the full vision, to see what phasing could save.
