This tool analyzes an Amazon Advertising bulk file you upload and produces estimates of wasted spend, projected ACoS, and related metrics. It is provided free of charge, without any login or payment required.
The output is an automated estimate based on the data in your file and the assumptions built into the tool. It is provided "as is," without warranty of any kind, and should not be treated as guaranteed savings, professional financial advice, or a substitute for reviewing your own account. You are responsible for any changes you make to your live Amazon campaigns.
Your bulk file is processed locally in your browser and is not uploaded to our servers. See our Privacy Policy for details.
You agree not to use this tool to upload data you don't have the right to use, or to attempt to disrupt, reverse engineer, or abuse the service.
