How the calculator works
Monthly lost revenue = missed leads per week × share that would book × average job value × 4.3 weeks. It counts the first job only, so the real cost — including repeat work, upsells, and referrals — is higher.
Not sure how many leads you miss? Track one normal week of missed calls, unanswered texts, and slow web replies. Our guide to what missed calls cost contractors walks through it with examples by trade, and how fast to respond to leads covers how to win them back.

Frequently asked questions
How do I calculate the cost of missed calls?
Multiply the leads you miss per week by the share that would have booked, your average job value, and 4.3 weeks per month. For example, 5 missed leads × 40% × $350 × 4.3 ≈ $3,010 a month.
What counts as a missed lead?
Any new-customer call you didn't answer, text you didn't reply to within about 15 minutes, or web, Google, or Facebook message you answered more than an hour later — or not at all.
