Worked example
How the number is worked out
A dental practice sitting at 4.6 stars, asking what half a star down would cost.
Starting from
Working
Half a star is worth one to two thousand a month at this volume. The impact model is stated on the page rather than assumed — roughly 12% per full star, from published research, which is where the 6% comes from.
How this was calculated
Methodology v2026.01.1. These estimates are directional and depend on inputs and assumptions.
- Monthly new customers × rating change impact.
- Average ticket converts customer impact into revenue.
- Gross margin optional for profit impact.
- Ranges reflect conservative conversion shifts.
FAQ
Does this assume a direct rating-to-revenue link?
It models an indirect conversion impact and keeps assumptions conservative.
Are these estimates exact?
No. They are directional so you can see the size of the leak before refining assumptions.
Can I change the assumptions?
Yes. Adjust the inputs to reflect your business and rerun the numbers.
Why use a range instead of a single number?
Ranges reflect uncertainty and help you stress-test best and worst cases.
Does this include profit?
Use the gross margin input to translate revenue impact into profit impact.
