Break Even ROAS Calculator — Free Online Tool
Running ads without knowing your exact break-even point is like driving without a fuel gauge — you might be fine, or you might run out long before you realize it. That's exactly the gap our Break Even ROAS Calculator was built to close. Instead of estimating your minimum required return or guessing at your true product costs, you enter your selling price, per-unit costs, and VAT details, and instantly see the exact ROAS you need just to break even — plus a target ROAS that includes a healthy profit buffer.
Whether you're running a dropshipping store, an established e-commerce brand, or managing Facebook and Google Ads campaigns for clients, this Break Even ROAS Calculator gives you the precise numbers you need before you scale any budget. Once you know your break-even threshold, check it against real campaign performance with our Google Ads ROAS Calculator to see whether current spend is clearing that bar.
What Is Break Even ROAS?
If you've searched what is break even ROAS, the short answer is this: it's the minimum Return on Ad Spend required for a campaign to cover its costs without generating a loss. Below this number, every sale actually costs you money. Above it, you're generating profit. Unlike a generic "good ROAS" benchmark you might see quoted online, your break-even ROAS is specific to your actual product costs, shipping, transaction fees, and tax treatment — which is exactly why a calculator built around your real numbers matters more than a rule of thumb.
What Is the Formula for Break-Even ROAS?
If you're looking for what is the formula for break-even ROAS, here's the core calculation this tool runs behind the scenes:
Break-Even ROAS = Selling Price ÷ Gross Profit per Unit
Where Gross Profit per Unit is your selling price minus your total net costs (cost of goods, shipping, transaction fees, and any other costs — each adjusted for reclaimable VAT). Once you know your break-even ROAS, adding a profit buffer percentage gives you a more realistic target ROAS to actually aim for, rather than just breaking even.
How Is Break Even Calculated in This Tool?
Wondering how is break even calculated with VAT involved? This calculator doesn't just subtract raw cost totals — it adjusts each cost line item for reclaimable VAT before calculating your true net cost. Here's the process:
Input your product's selling price, VAT included.
Use the slider to decide how much profit margin you want beyond break-even.
Add your cost of goods, shipping, transaction fees, and any other costs.
For each cost line, choose the VAT rate if that cost's tax is reclaimable, or "None" if it isn't.
See your break-even ROAS, net cost per unit, gross profit per unit, max allowable CPA, and buffered target ROAS update live.
Switch to the second tab to see break-even ROAS across a range of common margin percentages.

A Free Break Even ROAS Calculator Built for Real Selling Costs
Most generic break even roas calculator free tools online only ask for a cost and a price, ignoring the tax and fee details that actually change your numbers. This one is different — it's built specifically to handle the messier, real-world side of running a store: reclaimable VAT on cost of goods, separate shipping and transaction fee inputs, and a profit buffer you control rather than a fixed assumption.
Built for Ecom, Dropshipping, and Every Ad Platform
This tool works equally well as a break even roas calculator ecom teams rely on for daily campaign checks, and as a break even roas calculator dropshipping sellers use before committing to a new product test — since dropshipping margins are often razor-thin and highly sensitive to shipping and transaction costs. It also works perfectly as a facebook break even roas calculator, since the underlying math (price minus net costs, divided into price) applies identically whether your traffic comes from Facebook, Google, TikTok, or any other paid channel.
Break Even ROAS Calculator Online vs. Excel Spreadsheets
Plenty of sellers still rely on a manual break even roas calculator excel spreadsheet, rebuilding the same formulas every time a cost or VAT rate changes. The problem is that spreadsheets don't update instantly as you test new prices or costs, and a single broken formula reference can quietly skew every number downstream. Using a dedicated break even roas calculator online instead means your results update live with every input change, with the VAT and buffer logic already built in correctly — no formulas to maintain or accidentally break.
Understanding the Metrics This Tool Calculates
Net Cost per Unit
Your total cost of goods, shipping, transaction fees, and other costs, each adjusted for reclaimable VAT.
Gross Profit per Unit
Your selling price minus your net cost per unit — the actual profit available per sale before ad spend.
Max Allowable CPA
The highest amount you can spend to acquire a single customer without losing money on that sale. Compare this against your actual costs with our Cost Per Click Calculator to see how close your current spend is to that ceiling.
Target ROAS (with Buffer)
Your break-even ROAS adjusted upward by your chosen profit buffer percentage, giving you a realistic number to actually aim for.

Using the Break-Even ROAS Reference Matrix
Beyond the main calculator, this tool includes a quick-reference table mapping gross margin percentages directly to break-even ROAS and buffered target ROAS. If you already know your rough margin — say 35% or 50% — you can instantly see whether that margin puts you in "hard to scale," "moderate," "healthy," or "very profitable" territory, without entering exact cost figures. It's a fast way to sanity-check a new product idea before running the full calculation with precise numbers.
Tips for Getting the Most Accurate Results
Only mark VAT as reclaimable for a cost line if you can genuinely reclaim it — marking it incorrectly will understate your real costs.
Include every per-unit cost you can think of, including small transaction fees, since they add up quickly at scale.
Set a realistic profit buffer rather than 0%, since exact break-even leaves no room for returns, refunds, or ad platform volatility.
Recalculate whenever your supplier costs, shipping rates, or selling price change, since even small shifts move your break-even ROAS meaningfully.
Cross-check your result against the reference matrix to make sure your numbers make sense relative to your known margin range.
