Pay yourself a salary when the work won't

The number you build a budget on isn't your average month. It's your floor.

Average is the number that ruins people. A siding guy pulls $96,000 in a year and figures that's eight grand a month, so he buys a truck payment at $740 and a boat at $310 and a house payment that assumes eight grand keeps showing up. Then February arrives with $2,400 in deposits and three weeks of rain, and the whole structure starts eating the credit card.

The fix isn't discipline. It's a different number.

Pull twelve months of deposits and find the bottom

Open your bank app, go back twelve months, and write down what actually hit the account each month. Not what you invoiced. Not what the job was worth. What cleared.

You'll get something lumpy. Say it runs like this: 2,400 / 3,900 / 7,100 / 11,200 / 9,800 / 12,400 / 8,600 / 10,100 / 6,200 / 9,400 / 4,100 / 3,300. That's $88,500 for the year and an average of $7,375 a month, and the average is a liar, because four of those twelve months came in under five grand.

Take the three worst months and average those instead. Here that's 2,400, 3,300 and 3,900, which gives you $3,200. That's your floor. Not your budget yet, but the number that tells you what your business can produce on its worst run.

If you've got fewer than twelve months of history, use what you have and be more conservative. Two years is better than one, because one year might have been a fluke in either direction.

Two accounts and one transfer on the first

Every dollar of work income lands in one account. Call it the holding account. Nothing gets spent out of it. No debit card attached, no autopay, no Amazon.

On the first of the month, you move one fixed amount from the holding account into your regular checking. That transfer is your paycheck. Bills, groceries, gas, the kids' shoes, all of it runs out of checking like you're a guy with a W-2 and a boring job.

That single wall does most of the work. A $14,000 month never reaches your spending account, so it never feels like money you have.

Set the paycheck somewhere between your floor and your average, leaning hard toward the floor. In the example above, $4,500 is defensible. $6,000 is optimistic. $7,375 is how people end up selling the boat.

Your fixed costs have to fit under the floor

Add up what you owe every month no matter what: mortgage or rent, insurance, utilities, truck note, phone, minimum debt payments. That total needs to come in under your floor number, not under your paycheck number and definitely not under your average.

In our example, that means fixed costs under $3,200. Which is tight. Which is the point. If your fixed nut is $4,800 and your worst quarter produces $3,200 a month, you don't have a budgeting problem, you have a payment you can't carry, and no spreadsheet will fix it.

This is the part people skip because the answer is unwelcome. The truck you buy in July has to survive February.

Twenty-five to thirty percent comes off the top

If you're 1099 or you own the business, taxes aren't a bill. They're withholding you have to do yourself, and the IRS wants it four times a year, not once.

The mechanical version: when money lands in the holding account, move a set percentage to a separate savings account and pretend that account doesn't exist. Twenty-five to thirty percent is the range most self-employed people land in once you stack self-employment tax on top of income tax. Self-employment tax alone runs 15.3 percent on net earnings up to the Social Security wage base, and that's before a dollar of income tax.

Estimated payments are due around April 15, June 15, September 15 and January 15. Miss them and you get penalties even if you pay in full at filing.

There's a safe harbor provision that generally protects you from underpayment penalties if you pay in at least 100 percent of last year's tax liability, or 110 percent if your income was high. Whether it applies to you, and what percentage to set aside, depends on your situation. Ask a CPA. One hour of a professional's time in January is the cheapest thing you'll buy all year.

This is general education, not tax or financial advice for your circumstances.

What the overflow does, in order

Good months will pile cash in the holding account. Give that cash a job before it arrives, or it'll find one.

The order that works:

• Tax set-aside, first, always, automatically.
• Buffer to one month of your paycheck number sitting in the holding account. Now you can pay yourself in a dead month without touching anything else.
• Buffer to three months. This is the real goal. Three paychecks in the holding account means a bad quarter is a scheduling problem, not a crisis.
• Business stuff: the compressor you're nursing along, the insurance renewal, the truck tires.
• Everything after that goes to debt, retirement, or the house fund.

Notice that your personal emergency fund and your income buffer are two different piles. The buffer smooths the paycheck. The emergency fund covers the transmission. Mixing them means one bad month eats both.

Seasonal work is an annual problem wearing a monthly costume

If you pour concrete in Minnesota or run a landscaping crew, you already know December isn't a slow month, it's a zero month. Budget the year, not the season.

Take your realistic annual number, divide by twelve, subtract the tax percentage, and that's your ceiling for a paycheck. Then live on it in July, when you're making four times that and every voice in your head says you've earned a nicer trailer.

The July discipline is the entire game. Nobody fails at this in January. They fail in July.

Commission draws and the thing nobody reads

If you're on a draw, understand whether it's recoverable. A recoverable draw is a loan against future commission. Two soft months and you're not just broke, you owe the company money back out of the next good check.

Same with clawbacks. Sell a policy or a car or a service contract, get paid, and if the customer cancels inside the window, that commission comes back off a future check. So don't count a commission as income the day it pays. Count it when the clawback window closes, and hold the rest in the holding account until then. Read the comp plan. The clawback terms are in there, usually on a page nobody opens after the first week.

The good quarter is the dangerous one

Three strong months in a row and the temptation is to raise your paycheck. Resist it for at least six months, and when you do raise it, raise it by half of what the numbers say you can.

The honest trade-off: this system will make you feel poorer than you are. You'll have $19,000 sitting in a holding account while you're pricing a used Tahoe instead of a new one. That's not a bug. That's what solvency feels like from the inside when your income arrives in chunks.

Run it for a year. Then look at February, and notice that nothing happened.
