Free Amazon ACOS, TACoS & Profit Calculator (India)

ACOS (Advertising Cost of Sales) is ad spend divided by ad-attributed sales only. TACoS (Total Advertising Cost of Sales) is ad spend divided by TOTAL sales (ads plus organic). ACOS tells you how efficient a campaign is; a falling TACoS over time tells you your brand is building organic momentum and relying less on ads. Watch both: ACOS for campaign control, TACoS for overall account health.

Break-even ACOS is the point where the gross profit on a sale exactly equals the ad cost that produced it, so you make zero profit but no loss. It is your gross margin after all Amazon fees and product cost, expressed as a percentage. Any campaign running below break-even ACOS is profitable; anything above it is buying sales at a loss. This single number is the most important guardrail for your bids.

It accounts for the Referral Fee (your chosen category percentage), the Closing Fee, Weight Handling / shipping fee for FBA or Easy Ship, plus optional GST on fees and your product COGS. Amazon India fee rates change by category and over time, so we expose every input rather than hardcoding rates. Always confirm the current percentages against your Amazon Seller Central fee schedule before acting on the result.

No. Every calculation runs entirely in your browser using plain arithmetic. We do not send your costs, margins or ad spend to any server, and nothing is stored. You only share an email if you choose to download the PDF breakdown or book a free PPC audit, and that is entirely optional.
