Frequently Asked Questions
Everything you need to know before you start calculating.
Yes, completely free. All calculators are free to use without any limits, subscription, or payment. We intend to keep the core calculators free forever.
No account required. You can use every calculator on this site without registering or logging in. All calculations happen locally in your browser. We don't store your data.
There is no single "good" ROAS. It depends entirely on your gross margin. A 3x ROAS on a product with 60% gross margin is very profitable, while a 5x ROAS on a product with 80% COGS is a loss. Use our Break-Even ROAS Calculator to find your specific floor.
Break-Even ROAS = 1 / Gross Margin. If your gross margin is 40%, your break-even ROAS is 1 / 0.40 = 2.5x. Our Break-Even ROAS Calculator handles all versions of this calculation automatically.
A 3:1 LTV:CAC ratio is the widely cited benchmark for healthy D2C and SaaS businesses. Ratios below 1:1 mean you are destroying value. Ratios above 5:1 may indicate you are underinvesting in growth.
The calculators use standard industry formulas. Accuracy depends entirely on the quality of inputs you provide. If you use your actual spend, actual revenue from your backend, and real COGS, the outputs will be accurate.
Yes. Each calculator has a "Download PDF" button that generates a clean, formatted report. The PDF is generated locally in your browser. No data is sent to any server.
