Calculation method, coverage and version

Inputs used: Site type, Approx pages, Products (if e-commerce), Need AI features (chatbot, content gen)?.
Calculation approach: The calculator applies the rules and assumptions described in “How it works” to the values you enter. Rounding can cause small differences from an official or provider calculation.
Coverage: Business Tools. UK nations, tax treatment, local rules and provider criteria can differ; check the official sources shown below before acting.
Content version: No page-specific review date is currently published. Treat the result as indicative and verify current rules independently.

Not included unless explicitly requested: personal circumstances not entered, provider discretion, future rule changes, professional fees and case-specific exceptions. Read the full calculator methodology.

How it works

The estimator combines site type, complexity (pages, integrations, custom design) and build route (DIY / freelance / agency) to project a realistic build cost plus year-1 running costs.

Worked example

10-page brochure site for a consultancy via freelancer: £2,800 build + £180 hosting/yr + £600 SEO retainer = £3,580 year 1. Same site via agency: £8,500.

Who should use this

•Founders pricing a first website
•Established businesses upgrading
•Anyone comparing freelancer vs agency vs DIY

Common mistakes

×Underspending on copy and SEO — a beautiful site with no traffic is useless
×Forgetting maintenance budget (security, updates, content)
×Choosing custom code when Webflow/Shopify would do the job in 1/4 the time

Frequently asked questions

Webflow or WordPress?▾

Webflow for design-led marketing sites with no plugin sprawl; WordPress when you need a specific plugin ecosystem.

Do I need an app?▾

Almost never. A great mobile-responsive website beats a half-funded native app for 95% of small businesses.
