What is SEO actually worth to you?
Move the sliders to match your business. See what extra jobs from better Google rankings could mean in monthly revenue, against what SEO costs. No keyword volume needed. Numbers update live.
What an average new job is worth to you.
Pick a realistic number you actually want each month, not a miracle.
Typical pace: Steady build
Starter puts the foundations in. Progress toward the customer target above is usually steadier because the monthly scope is lighter.
Higher packages mean more work each month, which usually helps you reach the same customer target sooner. Not a guarantee.See what each includes.
Monthly revenue
£1,500
Monthly costs
£500
Monthly net gain
£1,000
£333 net per new customer
At these numbers the SEO cost is higher than the extra revenue. Raise job value or extra jobs, or lower the monthly cost, to see where it starts to pay.
Figures are a planning model. Monthly revenue is new customers times average job value. Monthly costs are the package you select. Net gain is revenue minus that cost. Higher packages usually mean more monthly work, so the same customer target is often reached sooner, but competition and your site still set the real pace.

How to read the three figures
Monthly revenue is extra jobs times average job value. Monthly costs are the SEO spend you set. Monthly net gain is revenue minus that cost. The line under net gain shows net per extra job, so you can see how hard each new job is working after SEO fees.
Why start with a small jobs number
Two or three extra jobs a month from better rankings is often enough for a scaffolder, plasterer or roofer to cover a sensible SEO retainer. If the net gain looks strong on cautious numbers, the case for SEO is clearer than if you need ten new jobs for it to work.
Job value matters more than vanity traffic
A groundworks firm with £4,000 average jobs needs fewer wins than a handyman on £180 tickets. Move the job value slider and watch how fast the net gain changes. That is why chasing broad traffic without knowing ticket size is a weak plan.
What to do if net gain looks weak
Raise job value if your real average is higher. Drop the extra jobs figure if you were being optimistic. Check the monthly cost sits where you would actually spend. If it still does not stack up, SEO may not be the first lever, or the wrong service mix is in the model.
Is this a forecast?
No. It is a live planning model. It does not promise rankings or subtract materials and labour. Use it to test whether a realistic job gain would cover SEO, then measure real enquiries once work starts.
FAQ
Common questions
Is this SEO ROI calculator free?
Yes. There is no charge and no account required. Everything runs in your browser and updates as you move the sliders.
What numbers should I put in?
Use your real average job value, or a cautious one. For extra jobs, pick a small realistic gain from better rankings, such as two to five a month, not a miracle figure.
Why is monthly SEO cost set at £500?
That is the Starter package. You can also select Growth at one thousand pounds or Premium at one thousand five hundred. Higher packages usually mean more monthly work, so the same customer target is often reached sooner, but that is not a guarantee.
Is monthly net gain the same as profit?
No. It is revenue from the extra jobs minus the SEO cost you set. It does not subtract materials, labour or other job costs. Use it to see whether ranking looks worth the SEO spend.
Can I trust this for my trade and town?
Use it as a planning model, not a forecast. Competition, map pack rankings and your close rate all change the real outcome. If you want a plan built around your towns and services, ask for a Growth Report.
