Profit First Formula
Take your profit first, then pay expenses with what remains
The Profit First Formula flips the traditional accounting equation. Instead of Sales minus Expenses equals Profit, you use Sales minus Profit equals Expenses. The traditional formula, which Michalowicz calls the Frankenstein Formula, treats profit as whatever is left over after all expenses are paid. The problem is that leftover profit rarely materializes because expenses expand to consume all available revenue.
The insight draws on Parkinson's Law: work expands to fill the time available, and similarly, expenses expand to consume the money available. When entrepreneurs see money in their operating account, they spend it. When the account is low, they panic and scramble to sell. This cycle of bank balance accounting keeps businesses trapped in survival mode, unable to build real profit.
By reversing the formula, you pre-determine a percentage of every deposit as profit and remove it before paying any bills. This forces the business to operate on what remains. The constraint does not destroy the business. Instead, it drives innovation and efficiency because you must find ways to deliver the same or better results with fewer resources. The formula works because it aligns with human behavior rather than fighting against it. Instead of relying on willpower to save profit at the end, you take it first and adapt your spending to what is left.
- Profit is not an event, it is a habit: Profitability comes from a series of small daily financial wins, not one big windfall or future exit
- Use the formula Sales minus Profit equals Expenses: Always remove profit from revenue before paying any bills, reversing the traditional accounting order
- Parkinson's Law applies to money: Just as work expands to fill time available, business expenses expand to consume all available revenue unless constrained
- Bank balance accounting is human nature: Entrepreneurs make spending decisions based on what they see in their bank account, so the system must work with this tendency rather than against it
- Constraint drives innovation: When you have less money available for expenses, you find creative ways to achieve the same results more efficiently
- Calculate your Real RevenueStart with your Top Line Revenue for the past twelve months. Subtract materials and subcontractor costs to arrive at your Real Revenue. This is the actual money your company generates from its own efforts, distinct from pass-through costs. A staffing firm billing three million but paying subcontractors two and a half million has Real Revenue of five hundred thousand.Pro tipReal Revenue is different from Gross Profit. Employee labor costs are not subtracted because you pay employees regardless of sales volume. Only materials and subcontractors are removed.
- Run the Instant AssessmentUsing the past twelve months of actual data, fill in what you actually spent on Profit, Owner's Pay, Taxes, and Operating Expenses. Calculate each as a percentage of Real Revenue. Then compare these actual percentages against the Target Allocation Percentages for your revenue range.Pro tipIf you think you have profit but it is not sitting in a bank account and was never distributed as a bonus on top of your salary, you do not actually have profit.WarningThis assessment can be emotionally devastating. Most businesses discover they are bleeding in Profit, Owner's Pay, and Taxes while overspending on Operating Expenses.
- Set up your bank accountsOpen four core accounts at your primary bank: Operating Expenses (checking), Owner's Pay (checking), Tax (savings), and Profit (savings). Then open two additional savings accounts at a separate bank for no-temptation Profit and Tax holding accounts. Do not enable debit cards, online bill pay, or any convenience features on the Profit and Tax accounts.Pro tipThe separation between banks is critical. Having the Profit and Tax reserves at a different institution creates friction that prevents impulsive withdrawals.
- Start allocating at current levels plus one percentBegin with your historical contribution levels for each category and add one percent. If your business has never had profit, start at one percent for the Profit Account. The amounts should be so small you barely feel them. The primary goal is to establish the habit of automatic allocation.Pro tipStart so small it feels insignificant. If your business cannot afford to set aside two percent of revenue, it is probably not a business worth pursuing.WarningDo not start at your target percentages. Going too big too fast leads to pulling money back out to cover bills, which defeats the entire process.
- Follow the 10/25 rhythmOn the 10th and 25th of each month, deposit all accumulated revenue into the Operating Expenses account, then immediately distribute predetermined percentages to each account. Pay all bills only on these two dates. This creates a predictable cash flow rhythm and prevents reactive spending.Pro tipPaying bills twice monthly rather than as they arrive eliminates the constant anxiety of watching money flow in and out. You always know when the next payment cycle is.
- Increase percentages by small steps each quarterEvery quarter, move your allocation percentages closer to your Target Allocation Percentages. Adjust by no more than three percentage points total per quarter across all accounts. Never take a step backward. Small consistent progress is far better than dramatic leaps that cannot be sustained.Pro tipYou could move Profit from five to eight percent, or spread three points across multiple accounts such as one percent each to Profit, Tax, and Owner's Pay.WarningNever reduce a percentage to accommodate a temporary revenue dip. The goal is forward progress only, even if the steps are tiny.
Alex, a local bistro owner, called Michalowicz's accountant Debra Michelini literally gasping for air. She did not have enough money to pay employees or vendors, let alone herself. Her accounting was so disorganized she did not even know to whom she owed money. She had not been collecting or remitting sales tax for years. Debra immediately implemented a customized version of Profit First with separate accounts for Profit, Owner's Pay, Tax, and Operating Expenses.
Jorge and Jose were initially reluctant to implement Profit First. They chose to start with a modest allocation of just two percent to profit. Jorge reasoned that if his business could not afford to set aside two percent of revenue, it was probably not worth pursuing. They adjusted percentages on a regular basis, factoring in short- and long-term needs and delaying equipment purchases they could not yet afford.
Mike Michalowicz developed the Profit First system after losing his fortune. He had built and sold two companies for millions, then blew through the money on extravagant purchases including multiple luxury cars and a series of failed angel investments. After hitting rock bottom, he began studying why businesses fail financially even when revenue is growing. He realized that the traditional accounting formula was behaviorally flawed. While watching a television segment about how using smaller plates leads to eating less, he connected the principle to business finances. If he reduced the plate size of his operating account, he would naturally spend less. This insight, combined with the pay-yourself-first principle from personal finance and the old-fashioned envelope budgeting system, became the foundation of Profit First.
