Operator Calculators

Focused, honest tools for the decisions operators actually face — sizing a goal, pricing an offer, weighing an automation. Each one does one thing, shows its math, and tells you what it can't know.

Everything runs in your browser. Nothing you type is saved or sent anywhere. Each tool starts with an example — replace it with your numbers.

Marketing Department

The economics of the offer and the funnel behind it.

Unit Economics Lab Work out LTV, CAC, and payback, and see whether the math behind a customer actually holds up. Open the calculator → Revenue Target Planner Start from a revenue goal and see what it takes — traffic, conversion, or revenue per customer — one lever at a time. Open the calculator → Offer & Pricing Scorecard Pressure-test an offer on value, differentiation, and price before you put weight behind it. Open the calculator →

The Operator’s Library

Field manuals, guides, and tools for the people who have to make the system actually work — written from production, not theory.

Verified Current

Every manual and guide is checked against the current release and carries the month it was last verified.

Corrected Openly

When a tool changes or we get something wrong, the fix is dated and noted on the affected guide.
