Your leak
Revenue walking out the door each month because the phone isn't being answered.
At this volume, every week of delay costs thousands. You are actively losing customers to competitors who picked up the phone first. TheKeyBot's AI captures ~90% of the calls you're missing — at your current numbers that's life-changing revenue within the first month.

How this calculation works (in plain math)
We want you to be able to verify the numbers, so nothing is hidden. The calculator uses:
monthly_calls = calls_per_day × work_days × (1 + seasonal_uplift) missed_calls = monthly_calls × missed_pct lost_bookings = missed_calls × booking_rate lost_revenue_month = lost_bookings × avg_ticket lost_revenue_year = lost_revenue_month × 12 // TheKeyBot recovery model recovered_monthly = lost_revenue_month × 0.9 net_monthly_gain = recovered_monthly − $500 // TheKeyBot flat cost roi_multiple = net_monthly_gain / 500
The 0.9 recovery factor reflects real-world AI conversion rates — not every missed call converts to a booking even when answered (some callers are out of service area, price shopping, or non-commercial). We use the conservative industry median.
Assumptions, caveats, and where your number might be off
Defaults are tuned for mobile / automotive locksmith shops. If you're a commercial / institutional locksmith with higher tickets and lower volume, bump the ticket up and the call-count down. The math will still hold.
Booking rate is the most sensitive input. If you don't know your booking rate from answered calls, 55% is a safe default for locksmith shops. You can verify it by auditing 100 recent answered calls against your CRM.
After-hours share varies by market. Urban markets with heavy nightlife (Houston, Las Vegas, Miami) run 45-55% after-hours. Smaller markets run 25-35%. This input drives the "your lives get better" side of the math — recovered after-hours revenue means the owner stops working 2 AM shifts.
What the calculator does not include (but that also matters): reduction in no-show rate from in-call deposit collection (usually 15-20% → 2%), Google-review velocity lift (typically 2-3× faster with automated follow-up), and re-engagement revenue from outbound AI calls to unbooked leads. These are directionally additive.
