Total upfront cost + monthly burn vs your per-unit profit. Get a realistic number of units (and months) to profitability.
The single most important number in your business, and the one most sellers cannot state off the top of their head.
Your break-even price is the selling price at which a product makes exactly zero profit, every cost covered, nothing left over. It sounds basic, but it is the number that quietly governs every important decision you make: how low you can discount during a launch, how much you can afford to spend on advertising, and whether a product is even worth importing from India in the first place. Sellers who do not know their break-even cold tend to make confident decisions on false assumptions, running promotions that lose money or advertising at a loss without realizing it.
Most sellers calculate break-even on landed cost alone and forget Amazon’s referral fee, the FBA fee, returns, and storage. The real break-even sits well above the "cost plus shipping" number people carry in their heads.
For a seller shipping from India, the full cost stack of a single unit is longer than it first appears, and each layer pushes your break-even price higher. There is the manufacturing cost at your factory; the freight and duty to land it in the US; the prep cost to make it FBA-ready; Amazon’s referral fee, typically around 15% of the sale price; the FBA fulfillment fee based on size and weight; and the often-forgotten provisions for storage, returns, and the occasional damaged unit. Only when all of these are counted do you have a true break-even.
The calculator above stacks these for you so you can see the real floor beneath your price. The gap between that floor and your intended selling price is your actual margin, the room you have to advertise, discount, and still come out ahead.
"You cannot price, discount, or advertise intelligently until you know the exact point where the product starts losing money."
Once you know your break-even, a lot of decisions become clear. Your maximum sustainable advertising cost per sale is the gap between your selling price and your break-even, spend more than that consistently and you are paying to lose money. Your deepest safe launch discount is bounded by the same number. And when you are evaluating a brand-new product to import, comparing its likely selling price against its break-even tells you immediately whether the margin is wide enough to be worth the risk and the working capital, before you commit to a production run and a container.
This is why break-even is the foundation other tools build on: your ACoS targets, your profit-margin projections, and your forecasts all start from this single number. Get it right and everything downstream is grounded in reality; get it wrong and every projection inherits the error.
Imagine a product you manufacture in India for the equivalent of $4 a unit. By the time it lands in your US warehouse, freight and duty might add roughly $2, taking your landed cost to about $6. Prep to make it FBA-ready adds, say, $0.75. Now Amazon takes its cut: on a $24.99 selling price, the referral fee of around 15% is about $3.75, and the FBA fulfillment fee for a small standard item might be another $4 or so. Already you are at roughly $14.50 in costs before you account for the reality that a percentage of units will be returned, and a few will be damaged or lost, which prudent sellers reserve for at perhaps another $1 to $1.50 per unit on average.
Add it up and the true break-even on that "$4 product" is somewhere around $16, not the $6 landed cost the seller might casually think of as their cost. On a $24.99 price that leaves real margin to work with, but a seller who believed their cost was $6 would wildly overestimate how much they could spend on ads or discount on a deal, and would lose money while feeling successful. The numbers above are illustrative, your real figures will differ, but the lesson holds: the honest break-even is always higher than the back-of-the-envelope version, and that gap is exactly where unprofitable decisions hide. The calculator exists to close that gap.
A break-even figure is the start of a pricing and advertising strategy, not the end of it. Knowing your floor tells you what is possible; deciding how aggressively to launch, how much margin to defend, and when to push for rank versus profit is the judgment that turns the number into a plan. Because we manage the freight, prep, fees, and advertising that all feed into this calculation, we can help you set a price and an ad budget that are anchored to your true costs from day one, so you are never guessing whether a sale actually made you money.
