What Is the Monthly Nut?

The monthly nut is the total fixed overhead a business must cover before earning its first dollar of profit. It's the floor your business stands on. Every dollar of revenue up to that number goes toward keeping the lights on. Every dollar after it is where profit actually starts.

If you only track one number in your business, this is it.

Where the Term Comes From

The word "nut" in this context comes from the theater industry. In the early 20th century, theater owners had to put up collateral, often a wagon wheel nut or a chest of valuables, before banks would lend them money to open a production. Each night, the box office first had to earn back enough to "get the nut out of the safe" and return it to the bank. Only after that threshold was crossed did the theater start making money.

The concept stuck. Today, every business has a nut: the fixed monthly cost that has to be covered before revenue turns into profit. Hit your nut and you survive. Beat it and you grow.

What's Included in Your Nut

Your monthly nut is made up of two types of costs.

Fixed costs are expenses that hit your account every single month for the same amount, regardless of whether you have one customer or one hundred.

• Rent or lease payments
• Staff salaries (everyone on payroll, not just contractors)
• Owner salary (more on this in a moment)
• Loan and debt payments
• Monthly software subscriptions
• Utilities on a flat rate

Semi-fixed costs are real expenses that don't bill monthly, so owners often forget to count them. The fix is simple: take any annual, quarterly, or irregular expense and divide it by 12 to get the monthly equivalent.

• Business insurance premiums (annual, divide by 12)
• Professional licenses and certifications (annual, divide by 12)
• Seasonal equipment maintenance (divide by 12)
• Annual software renewals (divide by 12)
• Quarterly tax payments averaged across the year

The semi-fixed category is where most owners leave money out of the calculation. A $3,600 annual insurance policy is $300/month whether it feels like it or not.

How to Calculate Your Monthly Nut

The math is simple. The discipline is the hard part.

Step 1: List every fixed monthly expense. Rent, payroll, loan payments, utilities, subscriptions. Write the actual number next to each one, not what you think it is from memory.

Step 2: List every semi-fixed or irregular expense. Insurance, licenses, annual renewals, anything that doesn't hit monthly. Divide each by 12.

Step 3: Add both lists together.

Step 4: That total is your monthly nut.

A business with $7,200 in fixed monthly costs and $4,800 in semi-fixed expenses (divided by 12) has a monthly nut of $12,000. That's the number the business has to clear every single month before it earns a dollar of actual profit. That works out to $400/day if you're open 30 days, or $480/day if you're operating on a 25-day work month.

Knowing that number changes how you look at every sales call, every project, and every slow week.

What Your Nut Tells You

Your monthly nut is a floor, not a ceiling. It tells you your minimum viable revenue: the amount you must hit to break even. Everything above it is profit margin.

Once you know your nut, a few things become clear:

You know your minimum price. If a job or project doesn't pay enough to carry its share of the monthly nut plus direct costs, you're losing money taking it. No amount of volume fixes that math.

You know your real break-even. Not the rough guess most owners carry around in their heads, but the exact number with real data behind it. You can check any week, any month against a concrete threshold.

You know when you're in trouble early. A business tracking its nut knows when revenue is trending toward it. A business that isn't tracking it finds out it's in trouble when the checking account runs dry.

You know how to evaluate growth decisions. Adding a new employee or a second location raises your nut. You can calculate exactly how much new revenue that decision requires before you're profitable again.

What your nut doesn't tell you is how much revenue you can generate. It's a cost measure, not a revenue forecast. It tells you where profit begins, not how far above it you'll land.

The Most Common Mistake: Forgetting to Pay Yourself

This one deserves its own section.

A large number of small business owners do not include their own salary in their monthly nut calculation. They list every other expense carefully, then leave their own compensation out entirely. The business looks profitable on paper. The owner is running on credit cards and adrenaline.

If you work in your business and you're not paying yourself a salary, you are subsidizing the business with your labor. That subsidy is invisible in the books, but it's real. You're essentially lending your business your time for free, and that loan never shows up on a balance sheet.

Your salary should be a fixed line item in the monthly nut calculation. A reasonable market salary for the work you do. When the nut includes that number, you get an honest picture of whether the business can actually support you, or whether it's only surviving because you're working for nothing.

If the business can't cover a reasonable owner salary, that's not a bookkeeping problem. It's a pricing or volume problem. And knowing that is the first step to fixing it.

Calculate Yours

The Break-Even Calculator walks you through this calculation step by step. Plug in your fixed costs, your semi-fixed expenses, and your average revenue, and you'll see your monthly nut, your daily nut, and how far above or below breakeven you're running.

The Budget Calculator is useful if you want to build a complete picture of both costs and projected revenue side by side.

Neither takes more than a few minutes. Both give you numbers that change how you make decisions.
