🧮 Conversion Rate & Cost
What is a Conversion Rate Calculator?
Conversion rate is the bottom-line measure of whether traffic turns into results. It captures the percentage of visitors who take the action you care about — buying, subscribing, or requesting a demo — and this calculator works it out from your own numbers in a tap.
Add your ad spend and it also returns cost per conversion, so you can see not just how well a page converts but what each result costs to win. Use it to compare landing pages, judge campaign efficiency, and prioritise the fixes that move revenue.
❓ Frequently Asked Questions
How is conversion rate calculated?
Divide conversions by total visitors and multiply by 100. For example, 25 conversions from 1,000 visitors is 25 ÷ 1,000 × 100 = 2.5%. A conversion can be any action you define — a purchase, sign-up, lead form, download, or booking — as long as you count it consistently against the visitors who had the chance to complete it.
What counts as a good conversion rate?
It depends on the offer, traffic quality, and industry. Many e-commerce sites hover in the low single digits, while high-intent landing pages and lead forms can run much higher. Rather than chase a benchmark, track your own rate over time and test changes — a relative lift on your baseline is what actually grows revenue.
What is cost per conversion and how is it worked out?
Cost per conversion (also called cost per acquisition) is your ad spend divided by the number of conversions it produced. Enter your spend here and the calculator returns it alongside the rate — for instance, $500 spend on 25 conversions is $20 each. Compare it to the value of a conversion to judge whether a campaign is profitable.
Why is my conversion rate low even with lots of traffic?
High traffic with few conversions usually points to a mismatch: the audience or keywords may not match the offer, the landing page may be slow, unclear, or asking too much, or the call to action may be weak. Segment by source, fix the biggest friction points, and re-measure here to confirm each change helped.
