Good metrics. Focus on increasing LTV to scale aggressively.
The Ultimate E-commerce Profitability Calculator
In 2025, e-commerce is no longer about “who can launch ads the fastest.” It is about Unit Economics. The Aisyntric Growth Engine is the most advanced calculator on the web, designed to replace your messy spreadsheets. Whether you are a dropshipper testing your first product or a 7-figure brand planning an exit, this tool adapts to your level.
Understanding Your Unit Economics
Before you spend a dollar on ads, you must know your numbers.
Cost of Goods Sold (COGS): The direct cost to produce and ship your item. Lowering this by even $1 can add $100k to your bottom line at scale.
Break-Even ROAS: This is your “survival number.” Calculated as Selling Price / Profit Margin. If your Facebook or TikTok ROAS drops below this, you lose money.
Real AOV (Average Order Value): Most tools ignore upsells. By increasing your AOV with post-purchase offers, you increase the amount you can afford to pay for a customer (CPA).
The Golden Ratio: LTV to CAC
Beginners obsess over first-order profit. Experts obsess over LTV (Lifetime Value). If you know that a customer will come back and spend another $50 in 60 days, you can afford to break even (or even lose money) on the first sale to acquire them. This tool’s Empire Mode lets you model this sophisticated strategy.

Frequently Asked Questions
What is a “Good” Break-Even ROAS?
A lower Break-Even ROAS is better. Ideally, you want a Break-Even ROAS below 1.5 or 1.6. This means you can be profitable even if your ads aren’t performing perfectly. If your Break-Even ROAS is above 2.0, your product margins are likely too thin for paid traffic (Facebook/TikTok Ads).
Why is “Blended ROAS” better than Facebook ROAS?
Facebook attribution is often inaccurate due to iOS privacy changes. Blended ROAS (MER) looks at your bank account reality: Total Revenue divided by Total Spend. It accounts for the “halo effect” of your ads.
How do I lower my CPA?
You can lower CPA by 1) Improving your ad creatives (CTR), 2) Improving your landing page offer (Conversion Rate), or 3) Targeting broader audiences to lower CPMs.
Is this tool accurate for 2025?
Yes. Unlike basic calculators, the Aisyntric Growth Engine accounts for modern variables like Agency Fees, Payment Processor costs, and Inventory Cash Flow constraints.
