Marketing ROI & Growth Calculator
Quick answer: This calculator estimates your current cost per acquired client, monthly marketing ROI, and what a realistic improvement in your lead-to-client conversion rate would be worth in additional revenue. It uses only the numbers you enter, runs entirely in your browser, and does not require an email address to see your results. It is a planning estimate, not a guarantee of outcomes.

Why we built this instead of gating it behind an email form
Most marketing calculators ask for your email before showing you anything. We would rather you see real numbers first and decide for yourself whether it is worth a conversation. If the math says your close rate is the bottleneck, not your lead volume, that changes what we would actually recommend building for you, and you do not need to hand over contact information to find that out.
What this calculator does not do
It does not predict your actual future results, it does not account for seasonality, sales-cycle length, or market-specific factors, and it is not a substitute for a real audit of your funnel. For regulated industries specifically, it also does not account for compliance-driven constraints on messaging or targeting that can affect achievable conversion rates. Treat the output as a starting point for a conversation, not a forecast.
FREQUENTLY ASKED QUESTIONS
Where does the “cost per acquired client” number come from?
It is your monthly marketing budget divided by the number of new clients your current lead volume and close rate produce in a month. It is a simple blended average, not a channel-by-channel breakdown.
Why does the calculator show a range of close-rate scenarios instead of one number?
Because we do not know your business well enough from four inputs to tell you exactly what is achievable. Showing a few realistic scenarios lets you see the shape of the opportunity without us pretending to more precision than four numbers can support.
Does a higher close rate always mean better marketing?
No. A low close rate can come from the marketing (wrong audience, weak offer, slow follow-up) or from something outside marketing entirely, like pricing, sales process, or service capacity. This calculator flags the opportunity, it does not diagnose the cause.
Is this specific to regulated industries like healthcare and addiction treatment?
The math works for any business. The caveat about compliance-driven constraints on messaging and targeting is specifically relevant if you are in healthcare, addiction treatment, financial services, legal, or another regulated vertical, where you cannot always chase the highest-converting message if it is not a defensible claim.
Do you save what I enter?
No. The calculation runs in your browser and nothing is transmitted anywhere unless you choose to click through to book a consultation.
