How Much to Spend on Amazon Ads in Australia: Set a Budget From Margin and Goals

Amazon lists a recommended minimum daily budget of 15 in local currency for Australia (A$15; confirm it in your ads console), as of October 2026. Beyond that floor, there is no right number. Set your budget by working backwards from your unit profit and the sales you want ads to drive, then adjust once you see real clicks. The method and an illustrative example are below.

What does Amazon say the minimum daily budget is?

Amazon's "basics of success" page says that, depending on your currency, it recommends a minimum daily budget, and the Australia row shows 15 in local currency. Three points about that figure:

• It is a recommendation, not a published hard rule. The page does not list a minimum bid for Australia, so you will find the lowest bid you can enter in the campaign builder itself.
• The page does not print a currency symbol for Australia. The column is headed "local currency", so confirm in your ads console that it is A$15 when you create a campaign.
• It does not say whether the figure is per campaign or across your account. Treat it as a per-campaign starting point and check the console.

Amazon states that you pay only when an ad is clicked and that you choose how much you are willing to bid for a click. On the seller advertising page, Amazon says you control spend by setting a budget and choosing a bid per click, and that Sponsored Products carries no monthly fee. Ads also need an active Professional seller account. The A$49.95 per month shown on that page is the Professional selling plan, not an advertising fee.

How do I work out a budget from my margin?

Do this per product, not per account. A product with a thin margin cannot support the spend that a high-margin one can.

1. Find profit per unit before ads. Take the selling price, remove GST, then subtract product cost, landed freight, the Amazon referral fee, and fulfilment (FBA or your own shipping). Amazon quotes its plan and FBA fees excluding GST. Use the tool in the profit calculator if you want a worksheet.
2. Convert it to break-even ACoS. Divide profit per unit before ads by the selling price. If you keep A$12 of a A$40 sale, break-even ACoS is 30%. Above that, each ad-driven sale loses money on the first order. Our ACoS guide covers what to target around it.
3. Pick a target ACoS below break-even. Leave room for profit, or pick a deliberate loss for a launch period. A target well under break-even is the normal starting point.
4. Set a sales goal for ads. For example, 100 ad-driven units a month.
5. Multiply. Ad sales goal times target ACoS equals monthly budget. Divide by 30 for the daily figure.
6. Sanity-check it against clicks. Daily budget divided by your cost per click tells you how many clicks you can buy a day. If that number is tiny, the budget will not produce usable data.

What does a worked A$ example look like?

Every input below is illustrative, not a benchmark. Replace them with your own.

Check: 3.3 orders a day needs about 33 clicks, and 33 clicks at A$0.80 is about A$27. The numbers agree, which tells you the goal is reachable on paper. If your real CPC turned out to be A$1.60, the same goal would cost about A$53 a day, or 40% ACoS, which is above break-even. At that point you would change the plan: lift conversion with better listing content, raise the price, or accept a lower unit goal. Your own CPC and conversion rate come from the console after a few weeks. Amazon does not publish a general Australian average CPC, so do not copy anyone else's.

How should the budget change by stage?

• Launch. Spend more than your steady-state target ACoS allows, deliberately, for a fixed window. The launch playbook covers how to cap that.
• Steady state. Hold ACoS near target and fund the campaigns that hit it. Cut or cap those that do not after a fair sample of clicks.
• Sale events. Amazon's Prime Day seller advice says to consider increasing ad spend to hold visibility amid heightened competition. See Prime Day ads for how to stage it.
• Low stock. Cut budget before you run out. Paying for clicks on a listing you cannot ship wastes money and hurts rank.

How should I split budget between campaigns?

Amazon lists three seller ad types for Australia: Sponsored Products and Sponsored Brands (both CPC), and Sponsored Display (programmatic). Sponsored Brands needs Brand Registry. A reasonable first split for a new seller is most of the budget on Sponsored Products, because it needs no Brand Registry and targets shoppers searching now. Add Sponsored Brands once you are registered and have several products, and Sponsored Display later for retargeting. Within Sponsored Products, campaign structure decides whether you can see which keywords earn their budget.

What mistakes waste a new seller's budget?

• Setting A$15 a day across ten products. Each gets too few clicks to learn from.
• Judging results after three days. Click volume at this level is small and noisy.
• Ignoring the profit side. A campaign at 25% ACoS on a product with a 15% margin loses money on every sale.
• Never reading the search term report, so budget leaks to irrelevant searches. Use negative keywords to stop it.
• Raising budget when the issue is the listing. More clicks on a page that does not convert only costs more.

FAQ

What is the minimum daily budget for Amazon ads in Australia? Amazon lists a recommended minimum daily budget of 15 in local currency for Australia (A$15; confirm in your ads console). It prints no currency symbol and no minimum bid, so confirm both in the campaign builder when you set up (as of October 2026).

Is there a monthly fee for Amazon ads in Australia? Amazon says Sponsored Products has no monthly fees and you pay only when shoppers click. You do need an active Professional selling account, which is charged separately at A$49.95 a month excluding GST.

Can I spend less than the recommended minimum? Amazon describes A$15 as a recommendation. Whether the console lets you enter a lower daily budget is something you can check in the campaign builder. A very low budget usually leaves too few clicks to learn from, so it is rarely worth it.

How long should I run ads before judging them? Long enough to gather a meaningful number of clicks per keyword, often two to four weeks at small budgets. There is no Amazon-published rule, so decide the click count up front, for example 100 clicks per target, and judge at that point.

Should I set one big budget or several small ones? Several focused campaigns, each with enough budget to get clicks. One large budget on a mixed campaign lets one keyword absorb most of the spend, and you cannot control it.

Does Amazon always spend the full daily budget? Amazon's budget page does not address pacing, so do not assume spend will equal budget each day. Check actual spend in the console's campaign reports and adjust to what you see.

Set a budget you can defend

Write the margin, break-even ACoS and daily budget for each product down before you open the console, and review them monthly.
