How Much Is My Business Worth? Why We Built a Free Calculator

Roughly one in three business owners has no idea what their business is worth — not a rough idea, no idea — and industry surveys consistently find that only about 14% of sellers have ever completed a professional valuation. For most owners, the business is the largest asset they will ever hold, larger than the house and the retirement account combined. And the number attached to it is a guess.

That guess usually comes from one of three bad sources: a broker who inflated it to win a listing, a story about a friend's business that sold for some remarkable multiple in a different industry in a different year, or simple hope — the number the retirement plan needs, worked backwards.

This article explains how buyers actually price a small business, which four factors move the number more than revenue does, and why we — a firm that buys businesses — built a free calculator that deliberately estimates low.

How is a small business actually valued?

At the size of company most American owners hold, buyers price businesses on a multiple of SDE — seller's discretionary earnings. SDE is the total financial benefit the owner takes from the business: net profit, plus the owner's salary, plus perks and personal expenses the business absorbs. It answers the buyer's real question: how much cash does this business put in its owner's pocket in a year?

That number gets multiplied by a market multiple. In recent BizBuySell market data, the average small business changed hands at roughly 2.7 times cash flow, with a median sale price around $349,000 — but the multiple swings widely by industry and, more importantly, by risk. Manufacturing and healthcare businesses routinely command more; restaurants and retail less. A revenue multiple (often around 0.7x) serves as a sanity check, but earnings drive the price. That's why a $3 million-revenue business with thin, owner-dependent profits can genuinely be worth less than a $1 million business that runs itself at strong margins.

The four factors that move your number more than revenue

1. Can it run without you? Owner-dependence is the single biggest discount in small-business M&A. If customers, key decisions, and daily operations all route through you, a buyer isn't purchasing a business — they're purchasing a job with your name still on it. Businesses with a functioning second layer of management earn premium multiples; deeply owner-dependent ones get cut hardest.

2. Customer concentration. If one customer is more than 25–30% of revenue, every buyer and every lender will price the risk that this one relationship leaves with you. Diversified revenue is worth more per dollar than concentrated revenue — every point of diversification adds value.

3. Clean, verifiable books. Buyers pay for provable earnings, not remembered ones. Financials a stranger can trust — accountant-prepared statements that reconcile with tax returns — close faster and at stronger multiples. Messy books don't just lower the price; they kill deals in diligence.

4. The trend line. Three years of steady growth earns a premium because buyers pay for where the business is going. A declining trend compresses the multiple faster than almost anything else — which is why the best time to value a business is years before you plan to sell, while the trend can still be shaped.

Why would a buyer give away free valuations?

Fair question — the number is the thing we negotiate over. The answer is about incentives. For much of the exit industry, the valuation is a sales tool: a broker who says $3 million wins your listing over the honest one who says $2 million, and the inflated number costs the broker nothing. You pay for it later, in a year of your business sitting on the market followed by price cut after price cut. It's a large part of why most listed businesses never sell.

A buyer lives in the opposite world. Every number we quote, we have to be prepared to stand behind — in diligence, in structure, at closing. Flattery would cost us money. So our calculator is built backwards from what businesses actually trade for, then discounted to be conservative. Some owners run it and are disappointed. We'd rather disappoint you in two minutes, for free, than have someone flatter you for a year, for a commission.

Why you should know your number even if you never sell

You know what your house is worth. You know what your truck is worth. The largest asset most owners hold sits unpriced for decades — and the first real number arrives at the worst possible moment: when you're tired, ready to leave, and out of time to change it. Known early, the number becomes a to-do list with a dollar figure on every line: delegate yourself out of daily operations, diversify the customer base, clean the books, protect the trend. Owners who run that list for two or three years routinely add six figures to their exit. Owners who skip it join the statistics.

Frequently asked questions

How do I calculate what my business is worth?

Start with SDE — net profit plus your salary plus perks — and multiply by an industry multiple, typically between 1.5x and 4x for main-street and lower-middle-market businesses. Then adjust for the four risk factors above. A free calculator automates exactly this math and shows which factors are helping or hurting you.

Is an online business valuation calculator accurate?

It's an educated estimate, not an appraisal. No tool can see your actual financial statements, contracts, or local market. A good calculator gets you to the right neighborhood and shows you what drives the number; a formal valuation or a buyer's offer, built on real financials, sets the street address. Be wary of any free tool that produces a flattering number — ask who benefits from you believing it.

What is the average multiple a small business sells for?

Recent market data puts the average at about 2.7x cash flow (SDE), with wide variation: stable, transferable businesses in favored industries can reach 3.5–4x, while owner-dependent or declining businesses may struggle to clear 2x.

Should I get a valuation if I'm not selling for years?

That's the best time. Every major value driver — owner-dependence, concentration, books, trend — takes one to three years to fix. A valuation three years out is a planning tool; a valuation three weeks before you want out is just news.
