Conversion Rate Calculator

Conversion rate is the core metric of digital marketing. Average e-commerce conversion rates are around 2–3%; landing pages built for one action often reach 5–10%. Small improvements multiply revenue from the same traffic.

How to use the Conversion Rate Calculator

1. Measure conversions for
2. Clicks or visits
3. Conversions
4. Value per conversion
5. Amount spent

Results update as you type, and every field accepts the units shown in its menu.

How it works

Choose whether you measure ads (clicks) or a website (visits), then enter the traffic, conversions, value per conversion and spend.

Tips

• Use figures for the same period (a month, a quarter or a year) for every input so ratios compare like with like.
• Track the metric over time – the trend usually tells you more than a single value.
• Compare your result with industry benchmarks, which vary a lot between sectors.
• Treat the result as a starting point for a decision, then check the assumptions behind each input.

Common mistakes to avoid

• Mixing monthly and yearly numbers in the same calculation.
• Using revenue where the formula needs profit (or the other way round).
• Forgetting hidden costs such as taxes, fees, overheads or your own time.

Inputs explained

What each result means

• Conversion rate = [Conversions]÷[Clicks or visits]×100
• Revenue from conversions = [Conversions]×[Value per conversion]
• Cost per conversion = [Amount spent]÷max([Conversions], 0.000001)
• Value per click or visit = [Revenue from conversions]÷[Clicks or visits]
• Return on spend = ([Revenue from conversions] – [Amount spent])÷[Amount spent]×100
