Free funnel calculators for the numbers that decide profit

These free funnel calculators turn your ad spend, conversion rates and deal values into the five numbers we check first on every audit: funnel conversion, cost per lead, ROAS, the cost of no-shows and the return on an AI voice agent. Each one runs in your browser, shows its formula and needs no email address.
Quick answer

Which funnel calculator should I use first?

Start with the funnel conversion calculator, because it shows every stage from visitor to sale and reveals the weakest step. Then use the cost per lead calculator to find your break-even lead price, the ROAS calculator to check profit, and the no-show and AI voice calculators to price the follow-up gaps.

How to use them together

Run them in order of the funnel. The conversion calculator gives you a baseline. If cost per lead looks high, the cost per lead calculator tells you whether it actually is, because a $60 lead is cheap when a customer is worth $10,000. If leads are fine but revenue is not, the problem is usually after the form: slow follow-up or missed calls, which the no-show and AI voice calculators put a dollar figure on.

Use real numbers from the last 30 to 90 days, not hopes. If you do not track show rate or close rate yet, that is the first fix, and our funnel KPI dashboard template lays out what to record each week.

What the numbers usually reveal

Across our audits, the leak is rarely the ad. Most accounts we review lose more revenue between the form and the sales call than on the landing page. Our speed-to-lead automation lifted lead-to-booking 2.4x across 60+ deployments on the same ads, and three-channel reminders push show-up rates as high as 88%. When the calculators point to a gap you cannot close in-house, the services page lists the build that fixes it, and the cost per lead glossary entry explains the terms.

Frequently asked questions.

Are the funnel calculators really free?

Yes. Every calculator runs in your browser with no sign-up, no email gate and no data sent to us. Change any input and the results update instantly. The formula is printed under each calculator so you can rebuild it in a spreadsheet and check the math against your own reports.

Where do I find the numbers to enter?

Ad spend, clicks and leads come from your ad manager. Booked calls, show rate and close rate come from your CRM or calendar. Deal value and margin come from your books. If any stage is not tracked, estimate it, then start recording it weekly so the next run uses real data.

How accurate are the results?

The math is exact; the output is only as good as the inputs. Use averages from at least 30 days and enough volume to be meaningful, ideally 100 or more leads. Small samples swing wildly, so treat early numbers as direction rather than a forecast you plan budget around.

Which number matters most in a sales funnel?

Cost per acquired customer against the gross profit that customer brings. Cost per lead and ROAS are useful because they arrive faster, but a cheap lead that never closes is expensive. The funnel conversion calculator shows cost per sale alongside cost per lead for exactly this reason.

Can you help if the calculators show a problem?

Yes. Each calculator page lists the fixes that move that number, from offer and page changes to speed-to-lead, reminders, AI voice qualification and Conversions API tracking. Builds go live in 5 to 10 business days and start at $999. Book a strategy call and bring your calculator results.
