Why most sellers don't know their break-even point

You can't hit a target you can't see. Most sellers guess their break-even. The math says otherwise.

01

You're estimating, not calculating

Most sellers round their costs, skip a few fee types, and call it a margin. That's not break-even analysis. It's a rough guess that gets more wrong the more SKUs you run.

02

Fixed costs get buried

Monthly storage, long-term storage surcharges, subscription fees, inbound shipping. These costs don't show up on a per-order basis but they directly affect how many units you need to sell.

03

Amazon changes fees quarterly

Referral rates, FBA fulfillment, storage surcharges. Each update shifts your break-even volume. If you're not tracking fee changes, your break-even from last quarter is already wrong.

04

PPC spend moves the target daily

A $500/day ad budget on a 100-unit/day product adds $5 per unit to your cost structure. Pause ads and break-even drops. Scale spend and it rises. You need live numbers.

What is a break-even calculator for Amazon sellers?

A break-even calculator tells you the minimum number of units you need to sell before your product becomes profitable. It factors in every cost: COGS, all Amazon fees, advertising spend, storage, and returns. Sell fewer units than your break-even point and you lose money on that product.

The challenge for Amazon sellers is that break-even isn't static. Amazon updates fee structures quarterly. PPC costs change daily. Storage rates spike in Q4. A product that broke even at 150 units last quarter might need 200 units this quarter. You need current numbers, not last month's spreadsheet.

Nova's P&L engine tracks all 40+ Amazon fee types, COGS per SKU, PPC spend at the product level, and returns. Every cost component you need for break-even analysis, updated automatically. No manual data gathering. No stale numbers.

The P&L view captures everything Amazon-related

The P&L view is the big one. It captures everything Amazon-related with the granularity to track down every unexpected expense, giving me a real profit statement I can run the business off of. No more guessing margins or waiting for end-of-month reconciliation.

Just go for it. You won't regret it

The Nova team has built something truly special. The days of clunky Looker Studio dashboards are over. They are communicative and collaborative, and work hard to make the platform as helpful as possible for their users.

Replaced hours of reporting with one dashboard

I manage multiple brands and Cockpit, P&L and Day-to-Day are now part of my daily workflow. What used to take hours across multiple tools I now see in one place. Antoine and Maxime are clearly building this with real seller challenges in mind, and they listen.

Break-Even Calculator: Frequently Asked Questions

Everything you need to know about calculating your Amazon break-even point.

Break-even is the exact number of units you need to sell before you start making a profit. It accounts for all costs: COGS, Amazon fees (referral, FBA fulfillment, storage, returns), PPC spend, and any fixed operational expenses. Sell fewer units than your break-even point and you lose money on that product.
The formula is: Break-Even Units = Fixed Costs / (Selling Price - Variable Cost per Unit). Variable costs include COGS, referral fees, FBA fulfillment fees, and per-unit return costs. Fixed costs include monthly storage, subscription fees, and PPC budgets. Nova tracks all of these automatically so you can see break-even per SKU without spreadsheets.
Profit margin tells you how much you keep per sale. Break-even tells you how many sales you need before you keep anything at all. A product can have a healthy 25% margin but still lose money if you don't sell enough units to cover your fixed costs like storage, ad spend, and inbound shipping.
Nova provides every data input needed for break-even analysis: all 40+ Amazon fee types per SKU, COGS, PPC spend, returns, and net revenue. You can see your complete cost structure per product and determine exactly where your break-even point falls. No manual data gathering required.
Amazon updates fees quarterly. Storage rates change seasonally. PPC costs fluctuate daily based on competition. Returns vary by product and period. Any of these shifts change your break-even volume. Nova tracks all of them in near real-time so you always know your current break-even threshold.
Yes. Nova supports 21 Amazon marketplaces with automatic currency conversion. Fee structures vary significantly between regions. A product that breaks even at 200 units in the US might need 350 units in Germany due to different fulfillment costs and VAT.
Under 5 minutes. Connect your Seller Central account through Amazon's official SP-API, add your COGS (manually or via CSV), and Nova starts tracking every cost line automatically. All 40+ fee types are captured from day one.
Nova starts at $29 per month with annual billing and includes a 14-day free trial. All plans include P&L analytics, fee tracking, COGS management, PPC analytics, and custom breakdowns. No credit card required to start.
