How many additional sales would equal the website cost?
Turn a £295, £495 or £695 project into a simple break-even number using your own average sale and margin.
Make the decision commercial
Compare the one-off price with the gross profit from an ordinary sale.
A cheaper website is not automatically better, and a more expensive one is not automatically more effective. This tool simply shows how many additional sales would equal the project price if those sales happened. It does not assume that a website change will create them.
Your numbers
Calculate the break-even point.
Use a realistic average customer value and gross margin. If you are unsure of margin, use the percentage left after the direct cost of delivering the work or product.
Everything is calculated in your browser. These figures are not sent to White Direction.
The figures show a mathematical break-even comparison only. They are not a prediction or guarantee of sales, enquiries, rankings or revenue.
Use the answer properly
A break-even number is a decision aid—not a promise.
The website still needs a clear offer, real proof, a working enquiry route and suitable traffic. White Direction does not guarantee rankings, enquiries or sales.
- Use an ordinary average sale, not your largest job
- Use gross profit rather than total revenue
- Check the existing website for avoidable friction
- Agree the scope before paying a deposit
- Track calls and forms after the work goes live
- Judge the result using real enquiries and revenue
Useful answers
What the calculation does—and does not—mean.
Does this predict how many customers I will get?+
No. It only compares project price with the gross profit generated by the figures you enter.
Why use gross margin instead of revenue?+
Revenue includes money needed to deliver the job or product. Gross profit gives a more realistic comparison with the one-off project cost.
What if I do not know my margin?+
Use a cautious estimate or ask your accountant. The result is only as useful as the figures entered.
