The missed-lead
calculator.
Ten seconds, five numbers, one uncomfortable truth: what your website loses every month to enquiries nobody answered. Run your own figures — the maths happens in your browser, not on our servers.
This free calculator estimates the revenue your website loses to unanswered out-of-hours enquiries. Enter your monthly visitors, enquiry rate and average job value; it applies a deliberately conservative 25% capture rate and shows the recoverable pounds per month — and how many months of a £49 chatbot that would pay for.
What is an unanswered
enquiry worth?
Pick your trade for sensible defaults, then adjust every field to your real figures.
From Google Analytics, Plausible or your hosting stats.
Visitors who call, email or use your contact form. Most sites: 1–5%.
What one won enquiry is typically worth to you.
Evenings, weekends, lunch hours — check your inbox timestamps.
Be honest: no same-evening reply usually means a lost lead.
These are estimates, not promises. Real recovery depends on your traffic, trade and follow-up. Nothing you type leaves this page.

do the maths?
Visitors → enquiries
Monthly visitors × your enquiry rate. 800 visitors at 3% is 24 people asking to give you money.
After-hours share
Enquiries × out-of-hours %. Evenings and weekends are when your website works alone.
The miss rate
After-hours enquiries × the % that never get a timely reply. That is your monthly leak, in leads.
Conservative recovery
Missed leads × 25% capture × job value. If only one in four converts, what is it worth?
800 visitors × 3% = 24 enquiries
24 × 40% out-of-hours = 9.6
9.6 × 70% missed = 6.72 leads
6.72 × 25% capture × £250 = £420 / month
£420 ÷ £49 = 8.6 months of HyperChat · £420 × 12 = £5,040 a year
Why instant answers matter: firms replying within the hour are dramatically more likely to qualify the lead than those replying a day later (Harvard Business Review, “The Short Life of Online Sales Leads”). A chatbot replies in under a second — see what chatbots cost and our flat £49 pricing.
