Profit First

Introduction

Mike Michalowicz, an entrepreneur who struggled financially despite running businesses, developed Profit First, first published in 2014 and revised later. He flips the usual formula: instead of Sales minus Expenses equals Profit, he suggests Sales minus Profit equals Expenses.

The system uses separate bank accounts and set percentages to make profit automatic.

Who should read this book?

Small business owners and freelancers who struggle with cash flow or never seem to profit.

Helps with: Get my money right, Start something of my own

The central message

Allocate a percentage of every deposit to profit first, then run the business on what remains, using separate accounts.

Key ideas and concepts

1. Flip the formula

   Sales − Profit = Expenses.

2. Small plates

   Separate bank accounts for profit, owner's pay, tax and operating expenses.

3. Percentages

   Allocate set percentages of income to each account.

4. Parkinson's Law

   Expenses expand to fill available money, so reduce what's visible.

5. Rhythm

   Transfer money on a regular schedule.

Deeper analysis

Profit First is simple and effective, using behavioural psychology to make profit automatic. Many small business owners say it transformed their finances.

It's repetitive and focuses on one system, and some businesses with uneven cash flow or investment needs may need to adapt it. It's not a substitute for an accountant. For struggling owners, it's very helpful.

Practical applications

• Open separate accounts for profit, owner's pay, tax and expenses.
• Start with a small profit percentage.
• Transfer money twice a month.
• Cut one unnecessary expense.
• Review percentages each quarter.
