Methodology
The calculator uses CPC and CPL benchmark ranges, country currency conversion, enquiry source, lead-to-client conversion, ecommerce conversion rate, AOV, margin, and ROI timing. Results are focused ranges because advertising outcomes are not fixed.
1. Market cost range
The calculator starts with editable USD CPC and CPL benchmark ranges, then converts them by currency and country market-cost index.
2. Conversion logic
Lead generation uses CPL, enquiry source, lead-to-client close rate, and optional client value. Ecommerce uses CPC, purchase conversion rate, AOV, and margin.
3. Practical context
WhatsApp enquiries can be cheaper and faster, while website forms usually provide better details. Follow-up speed still affects final conversion.
4. ROI timeframe
The calculator shows when ROI usually becomes clearer by business type, because real estate, B2B, ecommerce, clinics, and coaching do not close at the same speed.
5. No fixed promises
The output is a planning range based on benchmark averages. It is not an official Meta guarantee and should be checked against live Ads Manager data.
Lead generation formula
Estimated leads = budget divided by adjusted CPL. Possible clients = leads multiplied by lead-to-client close rate. Potential revenue appears only when customer value is entered.
Ecommerce formula
Estimated clicks = budget divided by adjusted CPC. Orders = clicks multiplied by website purchase conversion rate. ROAS = revenue divided by ad spend. Break-even ROAS = 1 divided by gross margin.
