CAC Calculator
Sales + marketing spend in a slice ÷ newly acquired customers counted the same window.
Open calculator →Funnel Conversion Calculator
End-to-end conversion from first funnel step population to completing customers.
Overview
Use when multiple steps hide where prospects disappear. Fixes one broken step beat polishing later steps nobody reaches.
When to use this calculator
- When an end-to-end rate looks fine but you suspect one step is leaking
- Before you fund a big funnel rebuild and want the drop-off location clear
- When sales and marketing disagree on where leads die
- When you compare two funnels and need the same step definitions on both
Rule of thumb
Multiply step rates only when people are counted once and identity matches across steps.
Terms used in this calculator
- Conversion rate
- Share of a clear baseline group—visits, sessions, leads—that finished the goal you named.
- CPC
- What you paid on average for one ad click.
- ROI
- Return compared to everything you counted as investment—often wider than ads alone when people say "full ROI."

Formula
Final step users ÷ first step users × 100. Identity stitching between steps matters more than calculators admit.
Example calculation
Using the default example values from the JSON seed for this tool:
- First-step users
- 5000
- Final-step users
- 250
Result: 5.00% (Funnel conversion rate)
How to interpret this result
End-to-end rate from first step to the final step you wired into the tool.
The biggest drop usually sits on one step—fix that first before polishing later steps nobody reaches.
User identity consistency across steps matters for accuracy.
Common mistakes
- Mismatched user identifiers between funnel steps.
- Different entry definitions for “started” vs marketing qualified.
- Comparing funnels with incompatible time windows per step.
What to do next
Landing page and CPA tools show whether the narrow problem is upstream or downstream.
How to improve this result
- Fix the step with the largest absolute drop before polishing minor steps.
- Pass the same user ID (or honest proxy) between steps so math is not fiction.
- Mirror ad copy on the first screen after the click to prevent message mismatch.

FAQ
- Do I need cohort windows per step?
- Yes when journeys run longer than your reporting window—or early steps look empty.
- How is this unlike landing page CR?
- Landing rate is single URL; funnel ties multiple milestones together.
- Can marketing-qualified leads mismatch sales counts?
- Constantly—align definitions before benchmarking.
- What about anonymous visitors?
- If they cannot progress identically across steps, the math is only a rough guide.
- Should I chase 100% overall?
- No realistic funnel achieves that—focus deltas after changes instead.
