Calculate the Drop-off Rate (by step):

Prompt
Calculate the Drop-off Rate (by step):
Use the values from the attached CSV to calculate Drop-off Rate for each step in the funnel using the following formula:

Drop-off Rate (Step i) = (Number of users who exit at Step i ÷ Total number of users who enter Step i) × 100

Provide columns in one of these formats:

Wide format (recommended):

"[Step 1 – users entered]", "[Step 1 – users exited]"

"[Step 2 – users entered]", "[Step 2 – users exited]"

…continue for each step

Long format (alternative):

"[Step Name]", "[Users Entered]", "[Users Exited]"

Output requirements:

A table of all steps with: Users Entered, Users Exited, and Drop-off Rate %, sorted highest → lowest drop-off.

Identify the primary bottleneck (highest drop-off step).

Compute and report the overall completion rate from first to last step for context: (final step entrants ÷ first step entrants) × 100.

After calculating each Drop-off Rate, report where it lands on the following scale (lower is better):

Very Good = below 10%

Good = 10–19%

Average = 20–29%

Poor = 30–39%

Very Poor = 40% and above

Next, analyze the responses in the column "[Column with qualitative explanations]" in the CSV (e.g., open-text notes or session observations) to identify common reasons for drop-off at the top 1–2 bottleneck steps and provide clear, actionable suggestions to reduce drop-off.
Sample output
Drop-off Rate — Example Report
Summary

Overall Completion Rate: 62% (from Step 1 entrants → Step 4 completions)

Highest Drop-off Step: Step 2 → Step 3 (Form Entry) at 28% (Average)

Key Finding: Majority of exits occur during the form entry step, especially on mobile.

Step-by-Step Breakdown
Step	Users Entered	Users Exited	Drop-off Rate	Rating
Step 1: Landing Page → Cart	1,000	120	12%	Good
Step 2: Cart → Form Entry	880	250	28%	Average
Step 3: Form Entry → Review	630	130	21%	Average
Step 4: Review → Confirmation	500	60	12%	Good

Key Observations

Step 2 (Cart → Form Entry) had the largest drop-off at 28%, pulling down the funnel’s overall success.

Step 3 (Form Entry → Review) also saw notable friction with 21% exits, linked to validation and field complexity.

Steps 1 and 4 performed relatively well, both under 15% drop-off (Good).

Qualitative Insights (from explanations column)

Top themes and share of mentions at bottleneck steps:

Form confusion (labels, required fields unclear) — 34%

“Didn’t know what to put for account number.”

Validation errors with no guidance — 27%

“Kept saying my phone number was invalid, but it looked fine.”

Too many required fields — 22%

“Felt like overkill, I gave up.”

Mobile formatting issues — 10%

“Fields were too small on my phone.”

Slow load after cart submission — 7%

Recommendations

Simplify form step — reduce fields, mark optional ones clearly, and group related inputs.

Improve validation feedback — inline, specific, and actionable error messages.

Optimize mobile UX — larger input fields, numeric keyboards for phone/zip, one-column layout.

Add progress indicator — reassure users of task length, especially at Step 2–3.

Test autofill and integrations (e.g., saved addresses) to reduce typing friction.

Next Checks

Run an A/B test simplifying the form (10 fields → 6 fields).

Track mobile vs. desktop drop-off after changes.

Monitor session replay heatmaps to see if validation errors reduce.

Target: Reduce Step 2 drop-off from 28% → ≤15% and overall completion rate from 62% → ≥80%.
