Landing Page Conversion Calculator

This calculator projects what happens to conversions, revenue, and cost per acquisition if a landing page's conversion rate moves from its current level to a target level, holding the same traffic and ad spend. Current Conversions and Target Conversions are both Monthly Visitors multiplied by their respective rate, so Additional Conversions / Month -- the gap between them -- grows directly with Monthly Visitors and with how much higher the Target Conversion Rate is set above the Current Conversion Rate; it shrinks (and can go negative) if you set a target below the current rate. Additional Revenue / Month simply multiplies that conversion gap by Avg Lead/Conversion Value. Current CPA and Target CPA divide Monthly Ad Spend by the respective conversion count, so a higher conversion rate spreads the same ad spend across more conversions and lowers CPA -- Current Conversion Rate has no effect on Target Conversions or Target CPA, and Target Conversion Rate has no effect on Current Conversions or Current CPA, since each rate only drives its own side of the comparison.

CPA Savings is simply Current CPA minus Target CPA. Current ROI and Target ROI compare each scenario's revenue against Monthly Ad Spend; both read as 0% if Monthly Ad Spend is entered as $0, since ROI is undefined without any spend to measure a return against. This tool assumes the additional conversions are fully attributable to the conversion-rate change alone -- it does not model traffic quality shifts, seasonality, or diminishing returns from the optimization work itself.
