Everyone asks the same question before they start: what will this cost me a month? Saying "you set your own budget" is true and useless. What you actually want to know is narrower: what does it cost to get a real result in my line of work?
This guide turns that into arithmetic. First the three numbers your bill comes from. Then the same calculation with real figures from twelve US sectors. There is a calculator further down where you can run your own keyword.
Every search volume and click price here came from our own keyword tool and was measured on August 12, 2026. These numbers move, so run the tool yourself for the current picture.
The short answer: three numbers
Your monthly bill in Google Ads is the product of three things:
- Monthly searches: how often people look for the keyword you are targeting.
- Cost per click: the average price of one click on that keyword.
- Your share of those searches: what portion of them turns into a click on your ad.
The formula is plain: searches × your share = monthly clicks, then clicks × cost per click = your bill.
The first two you can look up. The third is the one people get wrong, so it gets its own section below.
One click, one hundred and eighty-one dollars
Before the method, look at what the American market actually charges. This is the top of our measured list:
| Search | Monthly searches | Cost per click |
|---|---|---|
| car accident lawyer | 368,000 | $181.27 |
| personal injury lawyer | 301,000 | $147.96 |
| crm software | 90,500 | $35.78 |
| accounting software | 22,200 | $35.00 |
| hvac repair | 90,500 | $30.66 |
| boston moving company | 18,100 | $19.17 |
| dallas locksmith | 6,600 | $18.28 |
| hair transplant | 74,000 | $14.57 |
| los angeles dentist | 5,400 | $13.61 |
| new york plumber | 5,400 | $9.43 |
| office chair | 246,000 | $3.43 |
| running shoes | 368,000 | $1.22 |
Read the first and last rows together. "Car accident lawyer" and "running shoes" are searched exactly the same number of times each month, 368,000. One costs $181.27 a click and the other $1.22. That is a hundred and forty-eight times the price for identical demand.
Nothing about the keyword explains that gap. What explains it is the customer behind it. A single injury case can be worth six figures to a law firm, so paying $181 for the chance at one is rational arithmetic. A pair of running shoes leaves a few dollars of margin, so nobody can pay more than about a dollar for the visit.
The rule that falls out of this is worth carrying with you: a high click price does not mean the keyword is expensive. It means that business is profitable. Cheap keywords are not automatically good news.
Volume is not the bill
The second thing the table hides is that big numbers do not mean big spending. "Apartments for rent" gets a million searches a month in the United States and costs $1.64 a click. "Dallas locksmith" gets 6,600 and costs $18.28.
The reason is intent, not size. A million people browsing apartments are mostly looking, not signing. Someone typing "dallas locksmith" is standing outside a locked door and will call the first number that answers. Volume measures demand. It says nothing about readiness to buy.
A worked example
Take the New York plumber. The measured figures are 5,400 searches a month at $9.43 a click.
Three scenarios for the share of those searches that become your clicks:
- 2 percent: 108 clicks, roughly $1,018 a month.
- 5 percent: 270 clicks, roughly $2,546 a month.
- 10 percent: 540 clicks, roughly $5,092 a month.
Now push the question one step further. Of those 270 clicks, how many pick up the phone? Say one in twenty, so 13 calls. How many book a job? Say a third, so 4 jobs. Is $2,546 a fair price for four plumbing jobs in New York? Your average ticket answers that, and nothing else does.
This is where the number becomes useful. "What does it cost" cannot be answered alone. It only means something next to "what is a customer worth to me."
About that percentage
We need to be straight about the third number. Plenty of articles will tell you the average click-through rate on Google Ads. There is no single true figure. It moves with your position, your industry, your ad copy and the intent behind the search.
So this guide does not invent one. It runs three scenarios instead: 2 percent weak, 5 percent reasonable, 10 percent strong. You will read your real number off your own account once the campaign is live.
One more distinction, because it trips people up. The share used here is clicks divided by searches. Click-through rate in Google Ads is clicks divided by impressions. Your ad does not appear on every search, so the figure here is really your impression share multiplied by your click-through rate.
Work out your own number
Doing this by hand for your own business is unnecessary. Give our Google Ads cost calculator your sector and city and it does the same arithmetic, except across your whole keyword family rather than a single term.
It handles three things for you. It expands your core into its variants, it drops the searches you should never advertise on (job listings, salary lookups, research queries) and it keeps the keywords that carry the weight of the budget. It also shows you what it dropped, because that list is the first draft of your negative keyword list.
Setting the budget from the other end
Most businesses build a budget forward: "let's put in $2,000 and see what happens." That spends money without producing a decision.
Build it backward instead. Four steps:
- What is a customer worth? Take the profit on your average sale, not the sale price.
- How many clicks does one customer take? If you have no data yet, start at 2 percent, so 50 clicks per customer.
- What does one customer cost? 50 clicks × your cost per click. For the New York plumber, 50 × $9.43 = $472.
- Is that under your profit? Under means the ads pay for themselves. Over means you fix the conversion or the keyword, not the budget.
Run those four once and the budget question answers itself: as many customers as you want, priced accordingly.
Getting more out of the same money
Lowering your cost is not about spending less. It is about turning more of the same money into customers. Four leaks show up in nearly every account we take over.
Not knowing what you are paying for
Google shows your ad not only on the keyword you picked but on searches it considers related. The search terms report shows the difference: the actual phrases people typed.
Most advertisers get a surprise the first time they open it. A company bidding on "hvac repair" finds it has been paying for "hvac repair salary" and "hvac technician jobs." Those clicks come from people looking for work, not service.
An empty negative keyword list
A negative keyword blocks a search you do not want. Add "free" and your ad stops appearing where that word shows up. The rules are in Google's negative keywords documentation.
Do not invent the list. Pull it from the search terms report. In service businesses the usual suspects are free, jobs, salary, hiring, DIY, how to, and complaint.
Never touching match types
Google puts new keywords on broad match by default, which is the setting that appears on the widest range of searches. The three options are explained in Google's match types documentation.
If your budget is finite, start narrow. Run exact and phrase match, read the real demand off the search terms report, then widen deliberately.
A good ad landing on a bad page
The ad promises roof repair in Houston and the click lands on a homepage where roofing is one of eight services. The visitor leaves. You paid for the click and got nothing back.
There is a second bill for this. Landing page experience is one of the three parts of Quality Score, so a weak page does not just lose that visitor. It raises the click price across your whole account. The same mistake gets charged twice. We go through this in our guide to Quality Score.
Display campaigns and the cost nobody budgets for
Everything above concerns search ads. The Display Network works differently: your ad appears as a banner across websites, apps and videos. Google describes it as more than two million sites, videos and apps, reaching over 90 percent of internet users worldwide.
The line item that catches people out here is not the media spend, it is the production. A display campaign does not run on one image. It needs the same design at several standard sizes, and each size is its own piece of work.
We wrote a tool to remove that cost. Our HTML5 ad builder runs in the browser, produces the standard Google Ads sizes from one design and gives you an upload-ready file. It is free.
Is the money coming back?
You have the cost and you have closed the leaks. One question remains: does this turn a profit?
The measure is return on ad spend. Put simply: for every dollar you put into ads, how much revenue came back. Four dollars back on one dollar spent is a ratio of four. What the ratio needs to be depends on your margin, so there is no universal threshold.
Run it on your own figures with our return calculator. For a campaign with real numbers attached, read the Pınara Beach Hotel case study.
Where Google Ads sits
Google Ads is the paid half of search marketing. The other half is earning your place in the results without paying, which is SEO.
Timing is what separates them. SEO takes months and then holds. Google Ads brings traffic the day it goes live and stops the day the budget does. They are not rivals; most businesses need both. The numbers behind that comparison are in paid versus organic search.
What sets Google Ads apart from other channels is intent. On social platforms you interrupt someone doing something else. On Google the person is already looking for what you sell. Nobody typing "emergency plumber" is undecided about wanting a plumber. For the comparison, see our Facebook advertising statistics.
Common questions
What is the minimum budget for Google Ads?
Google sets no floor. You can start at a dollar a day. The meaningful minimum is different: you need enough clicks to cover the cost of acquiring one customer. For the New York plumber that was around $472. For a personal injury firm it runs into the thousands.
What happens when the ads stop?
The traffic stops the same day. Google Ads is rented visibility; you hold the position while you pay for it. Permanent visibility is what SEO buys, which is why running both is the healthier arrangement for most businesses.
Why does my cost per click keep changing?
The auction is live. Competitors move their bids, new advertisers arrive, seasons turn. If your Quality Score improves you hold the same position for less. If it slips, that position costs more.
Are these figures a quote?
No, they are a baseline. Your real bill moves with your Quality Score, what competitors bid and how often your ad actually appears. The only exact number is the one your own account reports after the campaign has been running.
