The formula
Lead Conversion Rate = (Booked Jobs / Qualified Leads) x 100
Use qualified leads, not raw inquiries. Spam, wrong-area leads, and tire-kickers should be filtered out before calculating, otherwise the metric becomes meaningless.
Benchmarks by trade
- HVAC: 25 to 45 percent (residential service calls)
- Plumbing: 30 to 50 percent
- Electrical: 25 to 40 percent
- Garage door: 35 to 55 percent
- Roofing: 8 to 15 percent (longer sales cycle)
Top operators using a Revenue Optimization System routinely see 1.5 to 2x the trade average.
What drives lead conversion rate
- Speed to lead (response time)
- Number of follow-up touches in the first 7 days
- Channel mix (SMS converts higher than email or voicemail)
- Quality of the qualifying conversation
- Ease of booking (live calendar vs callback request)
How to improve it without spending more on ads
Most service businesses can lift conversion rate 30 to 60 percent simply by closing the speed-to-lead gap and adding a structured 7-day follow-up cadence. That is exactly what a Revenue Optimization System like CHIIRP is built for.
