    Analyze stage-by-stage funnel conversion rates, identify drop-off, forecast required traffic, and estimate the revenue impact of improving each stage.

    Formula

    Stage conversion = next-stage count / prior-stage count x 100

    How to use the result

    Fix the stage with the largest recoverable absolute loss, not necessarily the lowest percentage rate.

    All stage counts should represent the same cohort and time window. Inputs and calculations stay in this browser.

    Analyze drop-off rates at each stage of your sales or marketing funnel and identify optimization opportunities.

    Stage-by-Stage Analysis

    Enter the number of users at each funnel stage to see conversion and drop-off rates.

    How to use the Funnel Conversion Calculator

    Use this tool to identify where a funnel is leaking, quantify your overall conversion rate, plan the traffic you need to reach a goal, and estimate the revenue upside from improving conversion.

    Stage Analysis

    1. Enter visitors or users at each funnel stage (e.g., landing page visits → add to cart → checkout → purchase).
    2. Select Analyze Stages to calculate step-by-step conversion and drop-off.
    3. Fix the biggest drop first; the largest leak usually yields the highest ROI on effort.

    Overall Rate

    1. Enter total Visitors and total Customers for the same period.
    2. Select Calculate Overall Rate to compute overall conversion and total drop-off.
    3. Use this as a baseline KPI for month-over-month tracking.

    Required Traffic

    1. Enter your Target Conversions (orders, sign-ups, leads).
    2. Enter the expected Funnel Conversion Rate based on historical performance.
    3. Select Calculate Required Traffic to estimate the top-of-funnel visitors you need.

    Revenue Impact

    1. Enter monthly visitors, Average Order Value, and your current vs improved conversion rates.
    2. Select Calculate Impact to estimate additional customers and incremental revenue.
    3. Use the output to justify CRO work and prioritize the highest-impact tests.

    Practical tips

    • Use a consistent cohort and timeframe; mixing traffic sources can distort stage drop-off.
    • Track both conversion rate and revenue per visitor; funnel improvements should translate to dollars.
    • Validate tracking at each stage before making decisions from the numbers.
