Free Tool for Practices
What is a slow first response actually costing your practice?
Your ads already paid for every inquiry. This calculator shows what the gap between the inquiry and your first real response costs in consults, procedures and revenue over a year — and what an under-five-minute response recovers from the same ad spend.
Step 1 · Your numbers
Your response time, in dollars.
Enter your monthly inquiry volume, your honest first-response time, and your funnel. The tool compares your funnel as it runs today against the same funnel answered in under five minutes.
Your inquiries and response time
Rough is fine, you can move every input. The one that matters most is the honest response time.
Form fills, calls, chats and DMs from all sources combined.
From the inquiry to the first real conversation attempt by a human, not the auto-reply. Count nights and weekends — the patient’s clock does not stop at closing time.
Your average completed case or first-year patient value. Rough is fine.
Of inquiries answered within minutes, how many book a consult. 40% is a healthy target.
Of booked consults, how many complete a procedure. No-shows count against this rate.

Conversion retained, by response time
Nothing in this math buys more leads. Every dollar here comes from answering the inquiries you already paid for while the decision is still warm.
This model is deliberately more conservative than the published research it is built on — the studies below measure odds ratios far steeper than these multipliers. Treat the number on screen as the floor of the leak, not the ceiling.
Why the first five minutes decide whether a high-ticket consult books, and where the delay actually comes from: Speed to Lead: Why the First Five Minutes Decide
Planning estimates only, based on the inputs you enter. Real results vary by market, offer, and follow-up quality. Not a guarantee of performance.
Step 2 · The evidence
The research is harsher than this model.
Two studies anchor everything this tool assumes. Both measured what actually happens to a lead as the response clock runs, and both found decay steeper than the multipliers used here.
Lead Response Management Study — Oldroyd, 2007
The study this field is built on. The odds of making contact with a new lead drop roughly 100x between a five-minute response and a thirty-minute response. The odds of qualifying the lead drop roughly 21x across the same gap.
Harvard Business Review, “The Short Life of Online Sales Leads” — 2011
An audit of 2,241 US companies. Firms that attempted contact within an hour were nearly 7x as likely to qualify the lead as firms that waited even an hour longer — and more than 60x as likely as firms that waited a day or more.
Those are odds ratios on contact and qualification. This calculator applies flat conversion retention instead — the share of your fast-response booking rate that survives at each response time — and sets every multiplier well above what the odds ratios would imply, on the assumption that your team eventually reaches many slow-responded leads anyway. The table is the whole model; there is nothing hidden behind it.
Share of fast-response conversion retained, by first-response time
| Under 5 min | 100% |
| 5–30 min | 60% |
| 30–60 min | 45% |
| 1–4 hours | 30% |
| 4–24 hours | 18% |
| Over 24 hours | 10% |
Step 3 · The mechanism
Why the minutes matter this much.
Motivation peaks at the form fill.
Weeks of private research end in one late-night inquiry. That submission is not the start of the decision — it is the peak of it. Every hour afterward, “I should do this” quietly reverts to “maybe next year.”
Silence loses to whoever calls first.
Most patients inquire with more than one practice. The first real conversation frames the procedure, the price and the questions to ask everyone else. Practices that call later are answering an agenda someone else set.
The clock runs nights and weekends.
Elective research happens at 9 pm and on Saturdays. A form submitted Friday night and answered Monday morning was not answered “same business day.” It was answered in sixty-two hours.
There is a second cost this calculator does not price: slow response corrupts your channel reporting and trains your ad account on the wrong leads. The full mechanism is in the article: Speed to Lead for Elective Practices
Step 4 · Your next step
Find out where your minutes are actually going.
The free Practice Growth Audit traces your recent inquiries through both halves of the system — the marketing that produced them and the response that received them — with real timestamps, and shows exactly where the minutes and the money leak. Or put a value on the patients themselves with the Patient Value & Budget Calculator.
