Conversion Rate Calculator

The formula

Conversions divided by visitors, as a percentage. 184 sales from 8,000 visitors is 2.3%. Define both consistently: sessions against sessions, or people against people. Mixing them is the most common way this number comes out wrong.

A conversion is whatever you count as success: a sale, a sign-up, a lead form, a booked call. Pick one per calculation. A page that converts 30% of visitors into newsletter sign-ups and 1% into buyers has two conversion rates, and both are useful.

A worked example

The figures above: 8,000 visitors and 184 sales.

• Conversion rate: 184 ÷ 8,000 = 2.3%.
• One sale for about every 43 visitors.
• Traffic needed for 500 sales at 2.3%: 500 ÷ 0.023 = about 21,739 visitors.
• Lift the rate by a quarter, to 2.875%, and the same 500 sales need about 17,391 visitors: 4,348 fewer to pay for.

Two ways to hit a target, and only one scales

More traffic costs money every month. A better conversion rate is paid for once and applies to every visitor after it, including the ones you were already paying for. The result above shows the traffic your target needs at today's rate, and how much less it needs after a modest lift.

What is a good conversion rate?

There is no single good number. It depends on what you sell, the price, where the traffic comes from and what counts as a conversion. A low-price product bought on impulse converts far better than an expensive one people research for weeks; a free sign-up converts better than a paid order. Many online shops see sales conversion rates in the low single digits, but the useful comparison is with yourself: the same page, the same traffic source, last month against this month.

Conversion rate for ads

Ad platforms usually report conversion rate per click: conversions ÷ clicks. That is not the same as your site's rate per visitor, because one click can bring a visitor who comes back later, and tracking misses some conversions. Use the rate per click to plan spend: it is the number the Google Ads and Meta budget calculators expect. Plan a Google Ads budget from it.

Then check what each conversion is worth to you. A higher conversion rate that brings cheaper orders can still lose money. Find the ROAS your margin needs.

How to improve it

• Match the page to the promise. If the ad or search result says one thing and the page opens on another, people leave.
• Make it fast and readable on a phone. Most traffic is mobile; slow or cramped pages lose people before they read anything.
• Remove steps. Every extra field, page or forced account sign-up at checkout costs conversions.
• Show what people need to trust you: the full price and fees, delivery or refund terms, and a way to contact you.
• Change one thing at a time, and give each change enough traffic to judge it.

Conversion rate and revenue per visitor

Conversion rate counts orders, not money. Two pages can both convert at 2.3% while one earns twice as much, because its average order is twice the size. Multiply the rate by the average order value to get revenue per visitor: at 2.3% and a $60 average order, each visitor is worth about $1.38.

That figure is what you can afford to pay for a visitor before profit and costs. A change that lifts the rate but pushes people to cheaper items, or a discount that lifts both rate and refunds, can leave revenue per visitor flat or lower. Track both numbers together, and judge a test on the one that pays the bills.

Averages hide the answer

A single site-wide conversion rate blends paid and organic, mobile and desktop, new and returning. Those often differ by several times over, so the average describes none of them. Segment before drawing a conclusion: the interesting number is almost always in one segment rather than in the blend.

Small numbers also lie. Two conversions from 40 visitors is 5%, and it is also noise. Wait for enough volume that one extra sale does not move the figure noticeably.

Frequently asked questions

How do you calculate conversion rate?

Divide conversions by visitors and multiply by 100. 184 sales from 8,000 visitors is 184 ÷ 8,000 × 100 = 2.3%.

What is a good conversion rate?

It depends on the product, the price, the traffic source and what counts as a conversion. Many online shops see sales conversion rates in the low single digits. Compare the same page and traffic source over time rather than with a general average.

How many visitors do I need for a sales target?

Divide the target by your conversion rate. At 2.3%, 500 sales need 500 ÷ 0.023, about 21,739 visitors.

Is conversion rate based on clicks or visitors?

Either, as long as you use the same base on both sides. Ad platforms usually use clicks; analytics tools usually use sessions or visitors.

What is the difference between conversion rate and click-through rate?

Click-through rate is the share of people who see an ad or link and click it. Conversion rate is the share of people who arrive and then do what you want, such as buying.

How can I increase my conversion rate?

Match the page to the ad or search that brought people, make it fast on a phone, remove checkout steps, show the full price and terms, and test one change at a time.
