How to Use the Amazon PPC Budget Calculator

The Amazon PPC Budget Calculator answers a simple question: how many clicks, orders, and revenue can you get from a daily ad budget? You enter four values: Daily Budget (default 50), Cost per Click (CPC) (0.75), Conversion % (8), and Average Order Value (AOV) (29.99). You do not create an account or install anything — the calculations run instantly in your browser.

In return, you get four results:

Clicks / Day — how many ad visits you can buy with your budget.
Orders / Day — how many of those clicks turn into purchases at the assumed conversion rate.
Revenue / Day — the sales value generated by the campaign.
ROAS — how much revenue you get for each unit of budget.

Example using the default values: a budget of 50 divided by a CPC of 0.75 gives 67 clicks; at an 8% conversion rate, those clicks produce 5.3 orders; and at an AOV of 29.99, that equals $159.95 in revenue and a ROAS of 3.2×. Want to test your own scenario? Just change the numbers in the fields. Amounts are shown in US dollars ($), but you can enter your own rates and calculate in any currency.

How to Choose Budget, CPC, and Conversion

The default values are a starting point, not a forecast for your store. You will get the most from the calculator by entering data you know from your own seller account:

CPC — use the average cost per click from your campaigns, or check current billing rates for your category and marketplace.
Conversion % — divide the number of campaign orders by the number of clicks and multiply by 100%. A new listing usually performs worse than a mature one.
AOV — the average order value from your sales; with bundles and higher-priced products, it will be clearly higher.
Daily Budget — the amount you can realistically spend on advertising each day, including when sales do not go your way.

With a modest budget and a high CPC, you will get few clicks, so testing takes longer. A budget that is too large with low conversion means fast spending with no return. The safest approach is to start with an amount you are prepared to spend on testing, then increase it as performance improves.

How to Interpret ROAS and ACOS in Amazon Ads

ROAS tells you how much revenue each unit of budget spent on advertising brings in: ROAS = campaign revenue ÷ campaign cost. The 3.2× result from our example means that for every 1 unit of budget, you get 3.2 units of sales.

The second metric sellers use is ACOS: ACOS = ad spend ÷ ad revenue × 100%. It is the inverse of ROAS, so if you know one, you can easily calculate the other: ACOS = 100% ÷ ROAS. At a ROAS of 3.2×, that is about 31%.

ROAS	ACOS
1×	100%
2×	50%
3×	33%
4×	25%
5×	20%

ROAS alone does not tell you whether a campaign is profitable. Product margin decides that: if you have little left after subtracting product cost, commission, shipping, and taxes, a campaign can be unprofitable even with a high ROAS. That is why you should compare the calculator result with your own costs, not with general forecasts from the internet.

Limitations and What the Tool Does Not Calculate

The calculator is a model based on four assumptions: budget, CPC, conversion, and average order value. It intentionally does not include, among other things:

Amazon platform fees, sales commissions, and Fulfillment by Amazon costs,
sales tax, VAT, and customs duties,
product cost, packaging, shipping, and return handling,
current ad rates, pricing, and fees — these change over time and depend on the marketplace and category,
the individual terms of your account and bids from competitors,
seasonality, demand changes, listing quality, reviews, and product availability, which are factors that shift conversion,
organic sales, which can also grow from ad visibility.

The result is therefore directional: it shows the scale of a campaign under the assumptions you enter, not guaranteed profit. Its greatest value is as a tool for comparing scenarios and checking whether a budget makes sense at rates you consider realistic. Before you make a decision, verify the current pricing and terms of your platform.

Scaling Daily Budget and Sales Forecasting

The most common use of the calculator is answering the question: what happens if I increase my budget? With unchanged CPC, conversion, and AOV, a budget change translates directly into clicks, orders, and revenue. The table below shows the default scenario.

Daily Budget	Clicks / Day	Orders / Day	Revenue / Day	ROAS
50	67	5.3	$159.95	3.2×

Notice one thing: with fixed assumptions, ROAS does not change, because both cost and revenue rise. Budget therefore determines scale, while ROAS determines efficiency. In practice, doubling your budget rarely produces exactly double the sales — higher CPC can make it more expensive, and conversion can fall when your ads reach a broader, less targeted audience.

That is why after every budget change you should return to the calculator with current campaign data and model the next scenario. Increase your budget gradually, watch daily results, and move money to where the return is best.

Frequently Asked Questions

How do I calculate ROAS in Amazon Ads?

ROAS is campaign revenue divided by campaign cost. The calculator calculates it automatically based on budget, CPC, conversion, and average order value — for the default values, the result is 3.2×.

How much daily budget do I need to start with Amazon Ads?

There is no single amount that works for everyone, because it all depends on CPC, conversion, and order value in your category. Enter your own rates into the calculator and see how many orders and how much revenue a budget you can safely spend on testing produces.

What is the difference between ROAS and ACOS?

ROAS is revenue divided by ad cost, while ACOS is cost divided by revenue and expressed as a percentage. They are two views of the same relationship: ACOS = 100% ÷ ROAS, so at a ROAS of 3.2×, ACOS is about 31%.

How do I convert a PPC budget into the number of orders?

First divide your budget by CPC to get the number of clicks, then multiply clicks by the conversion rate. For a budget of 50 and a CPC of 0.75, that gives 67 clicks, which at an 8% conversion rate produces 5.3 orders per day.

Does the calculator include Amazon commissions and FBA costs?

No. The tool calculates only from budget, CPC, conversion, and average order value, without platform fees, commissions, FBA, VAT, or product cost. Add those expenses yourself if you want to assess the real profit from a campaign.

How should I scale campaign budget when sales are growing?

Increase your budget gradually, and after each change check the new scenario in the calculator using current CPC and conversion. With fixed assumptions, a higher budget gives proportionally more clicks and orders, but in practice rates and conversion can change, so watch your campaign results.

Parameters and rates are estimates only. Before you decide, check current Amazon Ads pricing and platform fees.
