Use profit, not revenue
The honest number is what you keep after materials and your time. That is what really pays down the cost of the site.

Even one or two decent jobs a month can cover the cost of a website. After that, every extra enquiry is profit. It is an asset you own instead of paying again for every lead.

The honest number is what you keep after materials and your time. That is what really pays down the cost of the site.
If the maths works on one or two extra jobs a month, the decision is easy. Anything above that is a bonus.
A good site keeps working for years. Once it has paid for itself, the enquiries it brings in are close to free.
Every result comes straight from these formulas, with no hidden assumptions.
Jobs to cover the build cost
Website cost ÷ Profit per job (rounded up to a whole job)
Profit per month
(Extra jobs per month × Profit per job) − Monthly upkeep
Time to break even
Website cost ÷ Profit per month (rounded up to whole months)
Profit in year one
(Extra jobs × Profit per job × 12) − Website cost − (Monthly upkeep × 12)
Divide the one-off cost of the website by the average profit you make on a single job. If a site costs £799 and you clear £300 profit per job, three jobs it brings in cover the build. Everything after that is upside.
Use profit, which is what's left after materials, subcontractors, and your time, not the headline price you quote. That gives you a realistic picture of when the website has actually paid for itself.
It varies by trade and area, but many local businesses only need one or two extra enquiries a month for a simple, well-ranked site to pay for itself quickly. The calculator lets you test conservative numbers so the result is believable.
Pair the maths above with real pricing and the case for a website that brings in work.
See our fixed-price packages so the cost you plug into the calculator is a real number, not a guess.
Work out what to charge per day and hour so your profit-per-job figure is accurate.
Price a job properly so the profit you plug in above reflects what you actually keep.
Check your margin is set correctly so the profit-per-job figure above holds up in practice.
