Calculators
Free Marketing Tools
Three calculators, each answering one specific question. No email required to see a result, and every formula is published on the page so you can check the maths rather than trusting a black box.
Which one do you need?
| Tool | Answers | Use it when |
|---|---|---|
| Marketing Budget Calculator | What should I spend? | You're planning a budget, or wondering whether your current spend is sane |
| Local Service Ads ROI Calculator | Would LSA pay for itself? | You're in an eligible trade and deciding whether to start |
| AI Visibility Checker | Do AI assistants mention me? | Your buyers research before calling |
Why publish the formulas?
Because a calculator that hides its maths is a lead capture form wearing a costume.
Every tool here shows the inputs, the calculation and the assumptions. If you disagree with one of our assumptions — our 20% of gross profit target for acquisition cost, say — you can see it, change your inputs, and reach your own conclusion.
We also flag what each tool doesn't account for. The budget calculator can't see your capacity constraints. The LSA calculator can't see your review profile. Those limits matter more than the outputs sometimes.
Do I have to give you my email?
No. Every tool shows its result first.
There's an optional "email me this" on each, which some people find useful for sharing with a partner or accountant. Skipping it costs you nothing and changes nothing about the result.
Frequently asked questions
Are these tools actually free?
Yes, and ungated. Results display without an email address.
How accurate are the results?
The budget and ROI calculators are arithmetic — they're exactly as accurate as the numbers you put in, which is why estimating your close rate rather than measuring it is the biggest source of error. The AI visibility checker is a directional sample rather than a measurement, and says so on the page.
Can I use these for a business outside Nashville?
Yes. The budget and ROI calculators work anywhere. The AI visibility checker takes any city.
What if I don't know my close rate or cost per lead?
Estimate, then go and measure. Both tools show what changes when those inputs move, which is often more instructive than the headline number.
Do you store what I enter?
We log anonymised category and result bands to understand which businesses use the tools, and that data feeds our annual research report. We don't store your specific figures against you unless you choose to email yourself the result.
Want the real numbers instead of estimates?
The Growth Roadmap replaces every assumption in these tools with your actual data and your market's real search volume. $2,500, credited toward your first 90 days.
