Amazon PPC Calculator – Free ACoS & CPC Calculator for Amazon Ads

What Does the Amazon PPC Calculator Do?

This free tool helps you calculate your key advertising metrics, set smarter bids, and create a sensible daily budget, all in a single click. Enter your product details, then click Calculate to see your Target CPC, Break-Even CPC, and ACoS, Target ROAS, profit per order, and an optional suggested budget. If you’re not sure what something means, just hover over the tool-tip beside each metric, to get an explanation of what each metric is and how it impacts your ad campaigns.

The only information you’ll need to know is your product price, your cost of goods, your estimated conversion rate, and a target ACoS. There are also optional settings for Units per Order and Clicks per Day. When you are ready, hit Calculate. Your results appear instantly, and you have the choice to export everything to a CSV file if you choose. 

How to Use the Amazon PPC Calculator

This tool is super easy to use and will take you less than a minute to get your results. Here’s how it works:

Step 1: Enter your product details
Add your Product Price and your Total Cost per Unit. Your unit cost should include the product manufacturing costs, Amazon fees, and shipping. Then add your Conversion Rate and your Target ACoS. If you don’t know your exact conversion rate, I recommend choosing something between 9-15% which is the average on Amazon. For Target ACoS, if you don’t have something in mind, a number between 20 and 40 percent is reasonable.

Step 2: Open Advanced Settings (optional)
If you often sell multipacks or bundles, or if shoppers typically purchase more than one of your products at a time, I recommend choosing the appropriate “Units per Order” under advanced settings.

Additionally, if you want the tool to create a recommended budget for your ad campaign, you can also enter your desired number of Clicks per Day. This helps you get a rough estimate for a starting budget based on the number of clicks and the average cost per click.

Step 3: Calculate or try sample data
Once you’ve filled out all of your information, click Calculate to see results, or hit Try Sample Data to get a preview of how the tool works. Results include the two CPC figures you will use for bidding, your break-even point, your ROAS target, and profit per order.

Step 4: Export a record (optional)
Click Export CSV to download your inputs and outputs in a clean, one-line file. This gives you the option to upload your data to tools like Excel or Google Sheets.

Amazon Advertising Metrics Explained

The Amazon PPC Calculator uses a handful of common advertising terms to help you plan and optimize your ad campaigns. If you’re new to Amazon Ads, here’s a simple breakdown of what these numbers mean and why they matter.

ACoS (Advertising Cost of Sale)

ACoS tells you how much you’re spending on ads to generate each dollar of ad-driven sales. 

If you spend $20 to make $100 in ad sales, your ACoS is 20%. A lower ACoS usually means your ads are more efficient. Just remember that there’s no perfect number; what matters is how your ACoS compares to your profit margin. If it’s higher than your margin, you’re likely losing money on each sale.

Target CPC (Cost Per Click)

Target CPC tells you the price per click that still meets your ACoS goal. The calculator uses your target ACoS, your conversion rate, and your revenue per order to calculate it.

Start your bids at or a touch below this number. Then let your campaign run long enough to gather data. If your campaigns ACoS is higher than your goal, you can try lower bids or optimizing your product listing. If performance looks healthy, you can test small increases to your bids.

Break-Even CPC (Cost Per Click)

Break-Even CPC is the highest click price you can pay before profit from ad sales drops to zero. It comes from your price, your all-in unit cost, and your conversion rate.

When your actual ACoS is higher than this value, you lose money on ad-attributed orders. Use Break-Even ACoS as a guardrail when you choose a Target ACoS and when you review performance.

Target ROAS

Target ROAS shows how many dollars in sales you want for each dollar spent on ads. It is calculated as ad-attributed revenue divided by ad spend. For example, a ROAS of 3 means you would get $3 in sales for every $1 in ad spend.

If your live ROAS is below target, lower bids or improve your listing so more clicks turn into orders. If it is above target and profit per order looks healthy, you can consider increasing your ad budget in small steps to scale your campaign.

Conversion Rate (%)

Your conversion rate measures how well your product page turns clicks into sales.

If 100 people click your ad and 10 buy, your conversion rate is 10%. Strong conversion rates help you spend less per sale and keep ACoS under control. Weak conversion rates usually mean one of two things: you’re targeting the wrong keywords, or your product page needs improvement.

Frequently Asked Questions (FAQs)

What does an Amazon PPC Calculator do?

It turns your price, cost, conversion rate, and target ACoS into ready-to-use numbers. You get Target CPC, Break-Even CPC and ACoS, Target ROAS, profit per order, and a suggested daily budget. You can test with sample data and export results to CSV.

How do I calculate my break-even ACoS?

To calculate break-even ACoS, subtract your cost of goods and Amazon fees from your product price, then divide that by your product price. This tells you the highest ACoS you can afford before you start losing money on ads. The formula is: ((Price − COGS − Fees) ÷ Price) × 100

What is a good ACoS for Amazon PPC?

A good ACoS depends on your margins and your campaign goals. Many categories on Amazon see average ACoS in the 20%–40% range. Some sellers aim for 15%–25% when they want stronger profit, while higher targets can make sense for ranking campaigns or a product launch. 

What is a good conversion rate on Amazon?

Many listings land around 10% conversion on average, while well-optimized pages can reach the low-teens or higher. A range of 9%–15% is a good starting point for planning your ad campaigns. Always validate with your own Amazon reports and improve content, price, and reviews to increase your CVR.

Is the Amazon PPC Calculator free to use?
