Free business tools

Useful calculators for decisions—not vanity metrics.

Plan acquisition, inspect unit economics, quantify website opportunities, and test break-even assumptions. Every tool is free, runs in your browser, and uses only the numbers you enter.

Five focused calculators

From target to trade-off

Marketing · Customers · Conversion · Margin

Private inputs with transparent formulas
Better inputs, better decisions

Use the tools as a planning conversation.

Use one cohort

Align costs, leads, customers, and revenue to the same time period or customer group.

Use gross value

Revenue alone can hide delivery cost. Include margin when the decision concerns sustainable growth.

Use ranges

Compare conservative, expected, and optimistic assumptions instead of treating one estimate as certainty.

Ready when you are
