Use your own observed close rate. The defaults are illustrative assumptions, not performance forecasts.

Estimates are for planning purposes and assume steady close and contact rates. Your actual results depend on speed-to-lead, follow-up and offer.

How to read it

Cost per booked job is the only number that matters

In an illustrative scenario, a £20 lead closing at 5% costs £400 per booked job; a £45 lead closing at 20% costs £225. These are arithmetic examples, not measured shared or exclusive lead results. Use your own prices and conversion data.

This calculator does that maths for you. Adjust the close rate to compare exclusive vs shared scenarios, and watch how your true cost per acquisition and return on lead spend move. For most trades, exclusivity and speed-to-lead move these numbers more than price ever will.

How do you calculate cost per lead?

Cost per lead (CPL) is your total lead spend divided by the number of leads received. For example, £1,750 spent on 50 leads is a £35 cost per lead. But CPL alone is misleading - the number that actually matters is your cost per booked job.

How do you calculate cost per booked job?

Cost per booked job (also called cost per acquisition, or CPA) is your total lead spend divided by the number of jobs you actually win. If you spend £1,750 on leads and win 10 jobs, your cost per booked job is £175 - regardless of what each individual lead cost.

How do you calculate ROI on leads?

Return on lead spend is your profit from those jobs minus your lead spend, divided by your lead spend, shown as a percentage. If leads cost £1,750 and produce £18,000 in profit, your ROI is roughly 929%. This calculator works it out for you in real time.

Why does close rate matter more than cost per lead?

Cost per booked job depends on both the lead price and your observed close rate. A higher-priced lead only improves this result if it produces enough additional booked work. Test different assumptions in the calculator and compare them with your own results.
