Profit First

Mike Michalowicz

A simple cash-management system that flips the traditional accounting formula by taking profit first from every deposit, forcing businesses to become profitable immediately and permanently.

Profit First argues that the conventional formula Sales minus Expenses equals Profit is fundamentally broken because it treats profit as a leftover that never materializes. Drawing on behavioral science principles like Parkinson's Law, the Primacy Effect, and 'out of sight, out of mind,' Mike Michalowicz introduces a system designed to work with human nature rather than against it: take profit first by allocating a percentage of every deposit into separate bank accounts before paying any bills. Through his own story of building and losing fortunes, plus dozens of real entrepreneur case studies, the book provides a step-by-step method using multiple bank accounts, target allocation percentages, and a twice-monthly rhythm to make any business permanently profitable, eliminate debt, and create financial freedom.

The model

A behavioral cash-management model in which design levers (a separate-account allocation system, allocation percentages, and an enforced rhythm) trigger psychological states (perceived scarcity, removed temptation, profit focus) and behavioral patterns (frugality, innovation, expense discipline, debt reduction) that drive outcomes (profitability, growth, financial freedom).

Frameworks you can use

Use small plates: smaller available cash forces smaller spending.
Serve sequentially: allocate to profit and other accounts first, pay bills only with what remains.
Remove temptation: move profit and tax money out of sight and out of reach.
Enforce a rhythm: allocate and pay bills on a fixed twice-monthly schedule.
Profit is a habit, not an event.
Efficiency, not size, defines real business success.
