CPC, CPA, CTR & CVR Calculator

It is aimed at digital marketers and agency analysts who regularly convert between spend, clicks, impressions, and conversions without wanting to maintain a separate spreadsheet for each metric. All four calculations appear side by side so you can immediately see how a change in one metric flows through to the others.

Frequently asked questions
What is the difference between CTR and CVR?
CTR, or click-through rate, measures the percentage of people who saw your ad and clicked on it. It is calculated as clicks divided by impressions. CVR, or conversion rate, measures the percentage of people who clicked your ad and then completed a desired action on your site. It is calculated as conversions divided by clicks. CTR is a measure of ad relevance and creative effectiveness; CVR reflects landing page quality and offer strength.
What is a good CPC for Google Ads?
Average Google Ads CPCs vary substantially by industry. Legal, financial services, and insurance keywords often cost $5 to $50 per click. E-commerce and retail keywords typically range from $0.50 to $3. B2B software and technology keywords frequently fall between $3 and $15. Rather than benchmarking against an average, the more useful question is whether your CPC, combined with your conversion rate, produces a CPA that is within your target economics.
How do I use these metrics to diagnose campaign problems?
Work through the funnel in order. A low CTR points to an ad relevance or creative problem — your ad is not resonating with the audience seeing it. A normal CTR but low CVR points to a landing page or offer problem — people are interested enough to click but not converting. A normal CTR and CVR but high CPA points to a bidding or targeting efficiency problem — the right funnel mechanics are in place but you are paying too much to reach the audience.
