Without a unified view, it's challenging to quickly gauge the health of your marketing funnel. This Marketing ROI Calculator is designed to simplify that process.

FAQ
Q: How do you calculate marketing ROI using ROAS?
A: Modern ad accounting treats ROAS (Return on Ad Spend) as the primary efficiency proxy, calculated as Revenue divided by Spend. An ROAS of 4.0 means you earned $4 for every $1 spent. Unlike legacy ROI formulas that subtract cost first, this calculator prioritizes the direct multiplier so you can verify you're above the critical 4:1 threshold.
Q: What is a good CPA and CPL ratio?
A: Healthy CPA and CPL targets depend on your Customer Lifetime Value (LTV); a robust rule of thumb is keeping acquisition costs below 20–30% of LTV. Because benchmarks vary wildly by vertical, this tool lets you derive exact costs from your own funnel numbers so you can set accurate internal KPIs.
Q: How does this tool differ from a basic profit margin calculator?
A: This utility focuses exclusively on marketing efficiency, isolating ad-level variables like leads, conversions, and ad spend to output ROAS and CPA. It does not account for COGS, payroll, or software overhead. Once you validate your marketing efficiency here, use our business-profit-margin-calculator to determine full organizational profitability.
Q: Why does my conversion rate show as 0%?
A: Conversion Rate is computed as (Conversions ÷ Leads) × 100. A result of 0% indicates either your Conversion field is empty or zero, or you haven't entered a Lead count. Populate both fields to reveal the percentage; note that if Leads equal Conversions, the rate hits 100%.
