Quick answer
There is no fixed price for Google Ads. You set an average daily budget and, with cost-per-click bidding, pay each time someone clicks your ad. Google can spend up to twice your daily budget on a busy day but caps the month at about 30.4 times it. Australian business accounts pay 10% GST on top.
If you are deciding whether to start, or wondering whether your current spend is normal, this guide shows how the price is set, how to estimate clicks for your own keywords and what you pay on top of ad spend. It is part of our Google Ads help centre.
How Google Ads pricing works
Google Ads is an auction. Each time someone searches, Google decides which ads to show and in what order. You never pay a listing fee. You pay for results, usually clicks.
The auction and Ad Rank
Your position is set by Ad Rank. Google says Ad Rank looks at your bid, the quality of your ad and landing page, the search context and how competitive the auction is. A relevant ad with a useful landing page can beat a bigger bid.
Your maximum bid is the most you will usually pay for a click. Google's own cost-per-click help page says you are often charged less, sometimes much less.
Quality Score
Quality Score is a 1 to 10 diagnostic shown against each keyword. It reflects expected click-through rate, ad relevance and landing page experience. It is not a direct input to the auction, but low scores usually point to the same problems that make clicks dearer.
Daily budget and the monthly cap
You set an average daily budget for each campaign. On a busy day, Google can spend up to twice that amount. Over a month, Google says you will not be charged more than 30.4 times the average daily budget (30.4 is the average number of days in a month).

| Average daily budget | Most you can be charged in a day | Monthly charging limit (x 30.4) | Plus 10% GST |
|---|---|---|---|
| $20 | $40 | $608 | $668.80 |
| $50 | $100 | $1,520 | $1,672 |
| $100 | $200 | $3,040 | $3,344 |
These are limits, not targets. A campaign with narrow keywords may spend far less than its cap.
What does a click cost in Australia?
Click prices vary by industry, suburb, time of year and how many competitors are bidding. Legal, finance, migration and emergency trades are usually at the expensive end because each customer is worth a lot. Local hospitality and retail searches are often cheaper.
We are not publishing an industry table here because we would rather not quote averages we cannot back with a named source. You can get a reliable estimate for your own keywords in about ten minutes.
Estimate your own cost per click with Keyword Planner
- In Google Ads, open Tools, then Keyword Planner, then Discover new keywords.
- Enter three to five services you sell, written the way customers search (for example "emergency plumber" rather than "plumbing solutions").
- Set the location to the suburbs or city you actually serve, not all of Australia.
- Read the two bid columns. Google describes Top of page bid (low range) as roughly the 20th percentile of what advertisers have paid for a top-of-page position, and high range as roughly the 80th percentile, based on about the last 30 days. Source: Use Keyword Planner.
- Use the midpoint as a working cost per click for planning.
Tip
Keyword Planner shows bid estimates, not what you will actually pay. Treat the figures as a starting point and check your real average CPC after two to four weeks of live data.
What a realistic starting budget looks like
Work backwards from clicks, not from a round number. Here is the maths, using made-up figures purely to show the method.
| Step | Example figure | Where it comes from |
|---|---|---|
| Planning cost per click | $5 | Midpoint of your Keyword Planner range |
| Daily budget | $30 | Your choice |
| Clicks per day | About 6 | $30 divided by $5 |
| Clicks per month | About 180 | 6 x 30.4 |
| Enquiry rate | Unknown until tracked | Depends on your page, offer and phone handling |
| Monthly ad spend (cap) | $912 plus GST | $30 x 30.4 |
If your planning CPC is $15 instead of $5, the same $30 a day buys about 60 clicks a month. That is often too few to learn anything in a month. In that case, narrow the keywords or locations rather than spreading a small budget thinly.
Before you judge results, make sure enquiries are tracked. Our guide to fixing Google Ads conversion tracking covers that.
GST, invoices and billing in Australia
- GST: Google's Taxes in your country page says Google Ads sales in Australia attract 10% GST for accounts with Australian business addresses. The GST is added on top of your ad spend, so a $1,000 month costs $1,100.
- Tax invoices: Download them from the Billing section of your account, under Documents. Google says monthly invoices are available from about the fifth business day of the next month.
- When you are charged: With automatic payments, Google charges at the start of each month or when you hit your payment threshold, whichever comes first. With manual payments, you prepay and ads stop when the balance runs out. Source: Know your billing options.
- Currency: Set the account to AUD when you create it. Getting the billing country and currency right at setup saves trouble later.
If you are GST-registered, ask your accountant how to claim the GST credit. This is general information, not tax advice. For billing problems such as declined cards, see our Google Ads billing guide for Australia.
Ad spend vs management fees
Two separate costs often get blurred together.
- Ad spend goes to Google. It is charged to your card or invoice and appears on Google's tax invoice.
- Management fees go to whoever builds and runs the campaigns. They pay for keyword research, ad writing, tracking setup, negative keywords and ongoing changes.
Ask any agency to show both numbers separately in writing, and check that the ad account is in your name. At AR Digital, management fees are quoted in writing and kept separate from your ad spend, you own the ad account and management runs month to month with no lock-in. See our Google Ads management service for how we quote.
How to lower your cost per lead without cutting budget
- Remove wasted searches. Check the search terms report weekly at first and add negative keywords for jobs you do not do.
- Tighten locations. Target only the areas you service. Our 12 checks for Google Ads with no leads explains the "Presence" location setting.
- Match the page to the search. Someone searching "blocked drain Logan" should land on a page about blocked drains in Logan, not your home page.
- Answer the phone. Missed calls during ad hours are paid clicks with no return.
- Run ads when you can respond. If nobody answers after 5pm, test pausing evening ads.
- Improve ad relevance. Better Quality Score components usually mean cheaper clicks for the same position.
When to get help
If you have spent a few months and cannot say what a lead costs you, a specialist will check tracking first, then search terms, locations and bid strategy against your real margins.
