Frequently Asked Questions (FAQ)

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.

We support global currencies. Each calculator has a currency dropdown selector in the top right corner. You can choose from over 30+ major currencies including USD, INR, GBP, EUR, CAD, AUD, AED, and others. Choosing a currency automatically formats all inputs and outputs with the appropriate currency symbol and localized number formatting.

All calculations are performed 100% client-side. This means the math runs directly inside your web browser using client-side JavaScript. None of your sensitive business metrics, conversion numbers, ad spends, or customer volumes are ever sent to our servers or stored online. Your data remains completely private to you.

Cost Per Action (CPA) measures the direct ad spend divided by the number of actions (like leads or pixel purchase events) generated by a specific campaign. Customer Acquisition Cost (CAC) is a blended business metric that includes ad spend across all platforms, plus salaries, software subscriptions, agency retainers, and other overheads divided by the total number of new customers acquired. CAC is a bottom-line business health indicator, while CPA is an ad platform optimization metric.

Profit on Ad Spend (POAS) measures your net profit divided by your ad spend (POAS = Net Profit / Ad Spend). Unlike ROAS, which measures revenue and ignores product margins, POAS factors in the Cost of Goods Sold (COGS), shipping fees, credit card processing fees, and other variable expenses. A POAS greater than 1x guarantees your ads are profitable, while a ROAS of 3x could still lose money on thin margin products.

Meta Ads Manager uses conversion modeling and attribution windows (usually 7-day click, 1-day view) to claim sales, which can overlap with organic search or email conversions. Your ecommerce platform (e.g. Shopify) only records actual backend transactions. To get a picture of true blended returns, you should calculate your Marketing Efficiency Ratio (MER) blended across all active spend channels.

Blended ROAS (also known as Marketing Efficiency Ratio or MER) is calculated by dividing your total revenue by your total ad spend across all marketing channels. Tracking blended metrics prevents you from making scaling decisions based on single-channel dashboards, which often over-report sales due to overlapping attribution paths. A healthy blended MER ensures that your aggregate marketing investments are profitable.

We recommend running a light audit of your key performance indicators (CPMs, CTRs, and ROAS) daily to identify sudden anomalies. A comprehensive audit of your product economics, contribution margins, and platform attribution discrepancies should be executed weekly or bi-weekly. This cadence helps you catch pixel tracking errors early and pause unprofitable campaigns before they drain your budget.
