Google Ads ROI Calculator
Before investing in Google Ads, you want to know the likely return. We help you forecast your potential ROI based on your industry, budget and conversion data.
Realistic Forecasts
We use real industry data and your business metrics to calculate a credible ROI projection — not inflated estimates designed to sell.
Custom Projections
Generic calculators use averages. We factor in your specific industry, location, competition and average customer value.
Ongoing Measurement
Once campaigns are live, we track actual ROI against projections and continuously optimise to improve your returns.
Understanding Your Potential Google Ads ROI
Calculating Google Ads ROI involves more than multiplying clicks by conversion rates. You need to factor in cost per click, management fees, lead quality, conversion rates from lead to sale and average customer lifetime value. At Cloudswitched, we walk you through this calculation using data from your industry and your specific business to create a realistic forecast. This ensures you invest with clear expectations rather than blind hope.

We maintain benchmarks from dozens of UK industries, giving us accurate cost-per-click and conversion rate data to build reliable projections.
