Conversion Rate Calculator for Practice Funnels

Conversion rate is the number of people who took an action divided by the number who could have, times 100. 125 leads from 2,500 website visitors is a 5% conversion rate. This calculator runs the whole practice funnel (visitors, leads, consults, new patients), shows the rate at every step, and lets you test what a better rate on any step would add.

Type a new rate for any step. Blank keeps today's rate.

Overall conversion rate (website visitors to new patients)

1.2%

30 of 2,500.

  • Website visitors → Leads (forms, calls, texts)125 ÷ 2,5005%
  • Leads (forms, calls, texts) → Consults booked70 ÷ 12556%
  • Consults booked → Consults held55 ÷ 7078.6%
  • Consults held → New patients30 ÷ 5554.5%
Your math: Conversion rate = outcomes ÷ the stage before it × 100. Overall: 30 ÷ 2,500 = 1.2%.

Conversion rate formula

Conversion rate = conversions ÷ opportunities × 100. For a funnel, apply it to each pair of neighbouring stages:

  • Visitor to lead = leads ÷ visitors
  • Lead to consult booked = consults booked ÷ leads
  • Consult booked to held = consults held ÷ consults booked (the show rate)
  • Consult held to new patient = new patients ÷ consults held (the close rate)
  • Overall = new patients ÷ visitors

The overall rate equals the product of the step rates, so improving any single step lifts it by the same relative amount. Google's own definition is the average number of conversions per ad interaction, shown as a percentage.

Worked example: 2,500 visitors to 30 new patients

StepCountRate
Website visitors2,500–
Leads1255.0%
Consults booked7056.0%
Consults held5578.6%
New patients3054.5%
Overall30 of 2,5001.2%

Now suppose reminders lift the show rate from 78.6% to 90%. The same 2,500 visitors give 2,500 × 0.05 × 0.56 × 0.90 × 0.545 = 34.3 new patients, about 4 more a month, with no change in ad spend.

Which step to fix first

Start with the step that has the biggest gap to what you believe is reachable, and the cheapest fix. Show rate responds to reminders and deposits. Lead-to-consult responds to reply speed and to letting people self-book with online scheduling. Visitor-to-lead responds to the page itself.

Once you know your rates, turn them into cost with the customer acquisition cost calculator, and into dollars with the patient lifetime value calculator.

Frequently asked questions

How do you calculate conversion rate?

Divide the number of conversions by the number of people or interactions that could have converted, then multiply by 100. Google Ads uses the same approach: 50 conversions from 1,000 interactions is a 5% conversion rate. For a practice, 125 leads from 2,500 visitors is 125 ÷ 2,500 = 5%.

What is a good conversion rate for a med spa or practice website?

It depends on traffic source, offer and what you count as a conversion, so use your own history rather than a published average. Compare month to month using the same definitions. The calculator is built for that: change one step's rate and see the effect on new patients.

What counts as a conversion?

Whatever action you decide matters at that step: a form fill, a call, a booked consult, a consult held, a paid first visit. The key is to be consistent. Count the final conversion as a paid first visit, not a booking, because a booking that does not show costs you the same chair time.

Why track the funnel instead of one overall rate?

An overall rate tells you something is wrong but not where. If visitors turn into leads at a healthy rate but few leads become consults, the fix is follow-up speed, not more ads. Step rates point at the weak step so you spend effort in the right place.

Can a conversion rate be over 100%?

Only if you count more than one conversion per interaction, which Google Ads notes can happen when you track multiple conversion actions. In this calculator each stage is people, so a later stage cannot be larger than the one before it.

How do I use the what-if section?

Type a new rate for a step, such as 60% instead of 50% for consult to new patient. The calculator keeps your visitor count, applies the new rate and shows how many more new patients that makes. Add revenue per patient to see the dollar effect.

  • About Conversion rate. Google Ads Help

    Defines conversion rate as the average number of conversions per ad interaction, shown as a percentage (conversions ÷ interactions); notes it can exceed 100% when multiple conversion actions are tracked.

Planning math from the counts you enter. What-if results assume the other steps stay the same and are not a prediction.
