Is your website paying for itself? This calculator will help you calculate ROI based on traffic, conversions and customer value. You will see the payback period, revenue projection and comparison with Google Ads. The only such calculator in Polish.
Your business model determines conversion benchmarks. B2B sites convert at 2-4% but have higher deal values; e-commerce averages 2-3% with lower individual order values but higher volume.
This affects default conversion rate benchmarks and revenue calculation model.
The total cost of a website includes the initial build, ongoing maintenance, and marketing budget to drive traffic. Most businesses underestimate maintenance costs by 40-60%.

SEO, content marketing, social media, PPC — the budget driving traffic to your site.
The conversion funnel is the core of your website's ROI. Even a 0.5 percentage point improvement in conversion rate can double your revenue — this is why CRO (Conversion Rate Optimization) is one of the highest-ROI investments.
