Google Ads costs you two things: the ad budget you pay Google, and the fee you pay whoever manages the account. Most of our New Zealand clients start with $500 to $1,500 a month in ad spend, plus a flat $250 a month ex GST for management. There is no minimum spend set by Google, but below a few hundred dollars a month most local campaigns struggle to collect enough data to improve.
The cost per click itself is set by an auction, so it changes by industry, region and even time of day. This guide explains how that auction works, what drives the price up or down, and how to set a budget you can live with.
The two parts of a Google Ads bill
1. Ad spend
This is the money Google charges when someone clicks your ad. You set a daily budget, and Google bills against it. You only pay for clicks, not for your ad being shown, on standard Search campaigns.
A detail that surprises people: on any single day Google can spend up to twice your average daily budget if it sees more opportunity, but across a month it will not charge more than your daily budget multiplied by the average number of days in a month (about 30.4). So a $20 daily budget means a monthly ceiling of roughly $608, even if a busy Tuesday costs $35.
2. Management
Someone has to choose the keywords, write the ads, cut wasted search terms and check that the leads are real. That is either your time or an agency's fee. Fees in the market come in three shapes:
- A percentage of ad spend. The agency earns more when you spend more, which is not always in your interest.
- A flat monthly fee. Predictable, and it does not reward pushing your budget up. This is how we charge: $250 a month ex GST, open term.
- Setup fees plus a retainer. Common with larger agencies. Ask what the setup fee buys.
Our post on what you should actually pay for Google Ads management goes deeper on fee models.
How Google decides what a click costs
Every time someone searches, Google runs an auction among the advertisers bidding on that search. The winner is not simply the highest bidder. Google weighs your bid against the quality and relevance of your ad and landing page, and against how likely your ad is to be clicked.
In practice that means:
- A relevant ad on a relevant page pays less. If someone searches "emergency plumber Lower Hutt" and lands on a page about emergency plumbing in Lower Hutt, you will usually pay less per click than a competitor sending the same click to a generic homepage.
- Competition sets the floor. Industries where one customer is worth thousands of dollars, such as legal, finance and some trades, attract more bidders and higher clicks.
- Location matters. A campaign targeting greater Wellington competes with fewer advertisers than one targeting all of New Zealand.
- Timing matters. Clicks can cost more in busy periods, such as retail in the weeks before Christmas.
Working out a budget that makes sense
Start from what a customer is worth, not from what feels affordable. A simple way to do it:
- Estimate the value of a new customer. Use your average job or order value, or better, what a customer is worth over a year.
- Decide what you can pay to win one. If a typical job earns you $800 in margin, paying $100 to win it is a good trade.
- Estimate how many enquiries turn into customers. If one in three enquiries books, you can afford roughly a third of that per enquiry.
- Set the monthly budget to buy enough enquiries to learn from. Google's bidding needs conversion data to improve. A budget that buys two clicks a day gives it very little to work with.
This is why we suggest most clients start somewhere between $500 and $1,500 a month. On smaller budgets, focus matters more: fewer keywords, a tight area and Text Ads rather than display banners.
Where Google Ads budgets get wasted
Most of the waste we find when we audit an account comes from the same handful of settings:
- Broad keywords with no negatives. A "plumber" ad showing for "plumber salary" or "plumbing apprenticeship".
- Display network switched on by default. Banner impressions on unrelated websites, rarely buying customers for a service business. We keep budget on Text Ads and Shopping, where people are actively searching.
- No conversion tracking. If Google does not know which clicks became enquiries, smart bidding cannot learn.
- Sending every click to the homepage. A dedicated landing page usually converts better and lowers your cost per click.
- Targeting the whole country when you can only deliver in one region.

Is Google Ads worth it for a small business?
It is worth it when three things are true: people search for what you sell, a customer is worth meaningfully more than it costs to win one, and you can answer the phone or the form quickly when an enquiry arrives. A fast reply often matters as much as the ad itself.
It is less suited to products nobody searches for yet, or to businesses with very low margins per sale. In those cases, social media or SEO may be the better first spend.

Frequently asked questions
How much does Google Ads cost per month in NZ?
You choose the budget, and Google has no fixed minimum. Most of our NZ clients spend $500 to $1,500 a month on ads, plus a management fee if they use an agency. Ours is a flat $250 a month ex GST.
How much does a Google Ads click cost?
There is no single price. It is set by an auction for each search and depends on competition, your ad's relevance, your landing page and your location targeting. Competitive industries pay more per click than niche local services.
Can Google spend more than my daily budget?
On a single day, yes, up to twice your average daily budget. Across a month Google will not charge more than about 30.4 times your daily budget, so your monthly ceiling stays predictable.
Do you charge a percentage of my ad spend?
No. We charge a flat $250 a month ex GST, and your budget is paid to Google directly. Raising your budget does not raise our fee.
Is there a lock-in contract?
Not on the standalone Google Ads service, which is open term from day one. The website bundles that include ads have a 12-month minimum term, then go open term.
