How much are missed calls costing your business?

Adjust the sliders to match your business. The calculator shows the revenue at risk every month — and what an AI receptionist would cost to fix it.

Your numbers

Per booking, appointment, or job

Conservative assumption: not every missed call would have booked. Use 15–25% for most service businesses; 30–40% for appointment-heavy practices.

Monthly revenue at risk

$3,031

8.7 bookings/mo × $350 avg value

Annual revenue at risk

$36,372

The fix

AI Receptionist Starter

24/7 answering, 150 min/mo

$299/mo

Pays for itself if it recovers just 1 call/week — at your numbers, the ROI is 10.1×.

Why the math matters

75%+

of callers who reach voicemail don't call back — they call your competitor.

1 booking

recovered per month pays for the Starter plan several times over at most job values.

2 weeks

typical setup time — the AI starts answering before you've lost another month of calls.

This calculator uses conservative estimates. It does not account for lifetime customer value, referrals, or reputation effects of unanswered calls. Your actual at-risk revenue is likely higher.
