This free conversion rate calculator shows what share of your visitors take action. Enter visitors and conversions to get your rate. Add customers and sale size to see what each visitor is worth.
What is a conversion rate?
A conversion rate is the share of people who take the action you want. That action might be a call, a form, a booking or a purchase.
Google's conversion rate definition describes it as conversions divided by ad interactions, shown as a percentage. Google's example is 50 conversions from 1,000 interactions, which is a 5% rate.
The same page notes the rate can go over 100%. That happens when you track more than one conversion action or count every conversion from a visit.
How to calculate conversion rate
The formula is short. Conversion rate = conversions ÷ visitors × 100.
Say your website had 2,000 visitors last month. Sixty of them called or filled out a form. Your conversion rate is 3%.
Use the same date range and the same source for both numbers. Ad clicks pair with ad conversions. Website sessions pair with all site leads.
To see how rates differ by business type, read our guide on PPC conversion rates by industry.
How to use this conversion rate calculator
The conversion rate calculator has two tabs. Each one answers a different question.
The first tab finds your current rate. Enter visitors and conversions from the same period. Add customers won and your average sale to see the full picture.
The second tab plans a goal. Enter the traffic you expect and the rate you want to hit. The conversion rate calculator shows how many conversions that means and how many more you'd get compared with today.
Use the second tab before a redesign or a new campaign. It shows how many more leads a small lift would bring. Pair it with your average sale to see the revenue at stake.
Where do you find visitors and conversions?
Website visitors come from your analytics tool. Use sessions or users, and stick with the same one each time.
Ad clicks come from each ad platform. Use them when you want the rate for one campaign.
Calls come from call tracking. Forms come from your form tool or your analytics goals.
Customers won come from your CRM, job system or invoices. Match them to the same period as the leads.
If the numbers come from different tools, small gaps are normal. Tools count visits and conversions in slightly different ways.
Example: a home services website
Take a sample month for a home services company. It shows why one rate is rarely enough.
The numbers
In that month, the site had 2,000 visits. Visitors made 45 calls and filled out 15 forms, for 60 leads in total. The team booked 15 jobs at an average of $800 each.
The rates
Visitors converted at 3%. One in four leads booked, a lead-to-customer rate of 25%. Only 0.75% of all visitors became paying customers.
What it means
Revenue per visitor comes to $6. That number helps with ad budgets. If a click costs less than $6, and nothing else changes, the visit should pay for itself.
Where to improve
A better website lifts the 3%. Faster follow-up lifts the 25%. Both raise revenue per visitor, and the second one often costs less to fix.
What counts as a conversion for a service business?
Phone calls are the biggest one. Many local buyers call instead of filling out a form.
Contact forms and quote requests come next. Online bookings and chat leads count too.
Some actions are smaller steps. Clicking for directions, downloading a guide or starting a form show interest but aren't leads.
Pick the actions that lead to revenue and track those as conversions. Track smaller steps separately so they don't inflate the rate.
Why do phone calls change the math?
Many service businesses count only forms. Their conversion rate then looks far lower than it is.
Call tracking fixes that. A tracking number on the site counts calls from each source.
Set a minimum call length. Short hang-ups and wrong numbers shouldn't count.
Once calls are counted, the true rate can jump. Ad and page decisions then rest on real numbers.
Good conversion rates and how much traffic you need
The industry, the offer, the traffic source and the device all move it. Urgent services often convert higher than planned purchases.
Compare your own rate over time first. A steady climb matters more than matching someone else's number.
Then compare by source. Search ad visitors usually convert better than social visitors, since they were already searching. Typical ranges vary by industry, so use your own history first.
How many visitors do you need before trusting the rate?
Small numbers swing a lot. Three leads from 50 visitors is 6%. One more lead makes it 8%.
Wait for enough traffic before drawing conclusions. A few hundred visitors and a few dozen conversions give a steadier picture.
When testing a change, run both versions long enough to cover a full week. Weekday and weekend traffic behave differently.
Conversion rate at each stage of the funnel
One rate hides a lot. Splitting it by stage shows where the leaks are.
| Stage | Rate to watch | What moves it |
|---|---|---|
| Ad to visit | Click-through rate | Ad copy, offer, targeting |
| Visit to lead | Website conversion rate | Headline, speed, proof, form length |
| Lead to appointment | Booking rate | Response time, phone handling |
| Appointment to sale | Close rate | Pricing, sales process, trust |
Fixing the weakest stage usually pays off fastest. A strong site can't make up for leads that wait a day for a callback.
How does the traffic source affect conversion rate?
People arrive with different goals. Their source shapes how likely they are to act.
Search visitors tend to be ready to buy. They typed in a need.
Map and Business Profile visitors are close too. Many call straight from the listing.
Social visitors are earlier in the process. They saw an ad while scrolling and may need more time.
Email visitors already know you. Their rate is often higher than cold traffic.
Referral visitors from partner sites and directories vary widely. A trade group link may convert well, while a general directory may not.
Track each source on its own. A blended rate can hide a channel that converts poorly. It can also hide one that converts twice as well as the rest and deserves more budget.
Should you track conversion rate by device?
Yes. Phones and desktops behave very differently.
Phone visitors often call. Desktop visitors often fill out forms or browse more pages first.
A low phone rate usually points to a page problem. Small buttons, slow loads and long forms hurt most on phones.
Split the numbers by device in your analytics. Then fix the weaker one first.
What mistakes skew conversion rate?
Counting page views or button clicks as conversions. The rate looks great while leads stay flat.
Leaving out calls. The rate looks poor while the phone rings.
Mixing date ranges. Visitors from one month and leads from another give a false number.
Including spam form fills. Bots and junk leads inflate the count.
Comparing very small samples. A handful of visits can swing the rate wildly.
How does follow-up affect the real conversion rate?
The website conversion rate stops at the lead. The business still has to win the job.
Speed matters most. A lead called back within minutes is more likely to book. One left until tomorrow has often hired someone else.
Missed calls are a hidden leak. A caller who reaches voicemail often dials the next business on the list.
Track lead-to-customer rate next to the website rate. When the website rate is healthy and bookings lag, the fix sits with the phones and the sales process.
How often should you check conversion rate?
Monthly checks work for most small businesses. They smooth out daily swings.
Check sooner after a big change. A new page, a new form or a new ad campaign deserves a look after a week or two.
Keep a simple log. Note the date of each change next to the rate. Over time, the log shows which changes helped.
Seasons matter too. Compare a month with the same month last year when you can.
How to raise your conversion rate
Put the phone number at the top and make it tappable. Local visitors are mostly on phones.
Make the headline say what you do and where. Visitors decide in seconds.
Shorten forms. Most businesses only need a name, a phone number and a line about the job.
Show proof near the call to action. Reviews, ratings and real photos build trust.
Speed up the page. Every extra second of load time costs some visitors.
Send ad clicks to matching pages. Our landing page design work builds those. For a full program of testing and fixes, see our conversion rate optimization service.
How does conversion rate connect to cost per lead?
Conversion rate and click cost together set your cost per lead. Cost per lead = cost per click ÷ conversion rate.
A $4 click at a 4% rate gives a $100 lead. Raise the rate to 5%, and the same click gives an $80 lead.
That is why conversion work often lowers ad costs faster than bid changes. Try the numbers in our cost per lead calculator. More free tools are on our marketing calculators page.
Common questions
What is the conversion rate formula?
Conversions divided by visitors, times 100. Use the same date range for both.
Can a conversion rate be over 100%?
Yes, if you count more than one conversion per visit or track several actions at once.
Should I count phone calls as conversions?
Yes, for most service businesses. Calls are often the main way local buyers reach out.
What is the difference between conversion rate and close rate?
Conversion rate measures visitors who became leads. Close rate measures leads who became customers.
Does this calculator save my numbers?
No. Everything runs in your browser. Nothing gets stored or sent.
Should I use sessions or users as visitors?
Pick one and stick with it. Sessions count visits and users count people, so the rate will differ.
Can I calculate conversion rate for a single ad?
Yes. Use that ad's clicks as visitors and its tracked leads as conversions.
