Conversion Rate Calculator

Quick answer

A conversion rate calculator works out the share of visitors who complete a goal, using conversion rate = conversions / visitors x 100. Enter any two of conversion rate, conversions and visitors and leave the third blank. 50 conversions from 1,000 visitors is a conversion rate of 5 percent.

How to Use the Conversion Rate Calculator

  1. Enter any two of conversion rate, conversions and visitors.
  2. Leave the one you want to find blank.
  3. Read the result.
  4. See how many visitors per conversion it represents.

Here is what each result means:

What Is a Conversion Rate?

Conversion rate is the share of visitors who complete a goal you care about, such as making a purchase, signing up, or filling in a form. It is one of the most important measures in marketing because it shows how effectively your traffic turns into results, rather than just how much traffic you have.

The formula divides the number of conversions by the number of visitors and multiplies by 100. If 1,000 people visit a page and 50 of them buy, the conversion rate is 50 divided by 1,000, times 100, which is 5 percent. That means about one in every twenty visitors converted.

What counts as a conversion is up to you, and the same page can have several. It might be a sale, a lead, a newsletter sign-up or an app install. Because conversion rate focuses on outcomes, improving it often delivers more value than simply buying more traffic, since each extra percentage point works on every visitor you already have.

How Does the Conversion Rate Calculator Work?

It rearranges one relation to solve for whichever value you leave blank.

Formula: rate = (conversions / visitors) x 100, so conversions = rate / 100 x visitors, and visitors = conversions / (rate / 100).
  1. For the rate, divide conversions by visitors and multiply by 100.
  2. For conversions, multiply visitors by the rate as a fraction.
  3. For visitors, divide conversions by the rate as a fraction.

Conversion rate is the last step of the funnel; see the CTR calculator and the CPM calculator.

Conversion Rate Example

A page gets 1,000 visitors and 50 of them buy.

Calculation: rate = 50 / 1,000 x 100 = 5 percent. That is one sale for every 20 visitors. To reach 100 sales at the same rate, the page would need 2,000 visitors.

The Three Forms of the Conversion Rate Rule

One relation, rearranged for whatever you need to find.

To findUse
Conversion rateconversions divided by visitors, times 100
Conversionsvisitors times the rate as a fraction
Visitorsconversions divided by the rate as a fraction

All three come from rate = conversions over visitors times 100, so any two of the values give the third. This lets you forecast sales from expected traffic, or the traffic needed to hit a sales target at a known rate.

Comparing Conversion Rate with CTR

The two measure different steps of the same funnel.

A great CTR brings visitors, but the conversion rate decides how many of them act. Strong campaigns need both: an ad that earns the click and a page that earns the conversion. Improving the weaker of the two usually gives the biggest gain.

What Affects the Conversion Rate

The Offer and Price

A clear, compelling offer at the right price converts more of the same traffic.

The Landing Page

Fast, focused pages with an easy path to the goal lift conversions.

Traffic Quality

Visitors who match the offer convert far better than poorly targeted traffic.

When to Use a Conversion Rate Calculator

Measuring a Page or Campaign

Turn raw conversions and visitors into a comparable rate.

Forecasting

Estimate sales from expected traffic, or the traffic needed for a sales goal.

A/B Testing

Compare two versions of a page on the same conversion basis.

Common Mistakes

1. Counting the Wrong Denominator

Be consistent: use visitors, sessions or clicks, but the same one each time.

2. Mixing Conversion Types

Decide what counts as a conversion and count it consistently across the period.

3. Judging a Rate Without Context

Good rates vary by industry and offer. Compare against your own history.

4. Ignoring Small Samples

A rate from very few visitors is unreliable and can swing wildly.

5. Zero Visitors or Rate

Solving for the rate or visitors cannot divide by zero.

Accuracy and Limitations

The relation is exact; only the displayed decimals are rounded.

What it calculates accurately

  • Conversion rate, conversions or visitors from the other two
  • The visitors per conversion
  • Any campaign or page size

What it does not do

  • Judge whether a rate is good for your industry
  • Account for small-sample uncertainty
  • Measure revenue or profit per conversion
  • Separate new and returning visitors

How We Compute the Conversion Rate

Method
The relation rate = conversions / visitors x 100, rearranged for the value you leave blank.
Inputs used
Any two of conversion rate, conversions and visitors.
Assumptions
A consistent denominator; a clearly defined conversion; the same period throughout.
Rounding
Rate to two decimals; conversions and visitors to whole numbers.
Edge cases
Zero visitors when solving for the rate, or zero rate when solving for visitors, is not allowed.

Frequently Asked Questions

What is a conversion rate?

It is the share of visitors who complete a goal, such as a purchase or sign-up, as a percentage. 50 conversions from 1,000 visitors is a 5 percent rate.

How do you calculate conversion rate?

Divide the conversions by the visitors and multiply by 100. For 50 conversions from 1,000 visitors, that is 50 over 1,000 times 100, which is 5 percent.

What is a good conversion rate?

It varies by industry and offer, but many websites average around 2 to 5 percent. Compare against your own history rather than a single benchmark.

What counts as a conversion?

Any action you set as a goal: a sale, a lead, a sign-up, a download or an app install. Define it clearly and count it consistently.

How do I find conversions from the rate?

Multiply the visitors by the rate written as a fraction. Leave the conversions field blank and enter the rate and visitors to solve for it.

What is the difference between conversion rate and CTR?

CTR is clicks per impression, earlier in the funnel. Conversion rate is the share of visitors or clicks that complete a goal, later in the funnel.

Should I count visitors, sessions or clicks?

Any of them, as long as you are consistent. Pick one denominator and use it every time so your rates are comparable.

How can I improve my conversion rate?

Sharpen the offer, speed up and simplify the landing page, and send better-targeted traffic. Small gains apply to every visitor you already have.

Is my information saved?

No. The calculation runs in your browser and nothing you enter is stored or sent anywhere, unless you choose Save, which keeps the result only on this device.
