What Is Your Business Worth? Valuation Basics

Your business is worth what a qualified buyer, financed by a real lender, will actually pay for it — and nobody can hand you that number from a formula. What a good valuation process can do is give you an honest, defensible estimate built from your real financial performance, checked against how similar businesses have actually sold, and grounded in what a lender will lend against. If you're getting ready to sell, thinking about bringing in a partner, or just want to know where you stand, understanding the method matters more than chasing a headline number.

There is no universal formula — but there are three recognized approaches

Professional appraisers, and the IRS itself, have long recognized that valuing a closely held business is a judgment call built on multiple methods, not a single formula. The IRS's long-standing guidance on valuing closely held stock — Revenue Ruling 59-60, issued in 1959 and still the framework cited in valuation work today — states plainly that no formula can be devised that will be generally applicable, and instead directs the appraiser to weigh a list of factors about the specific business: its history, the economics of its industry, its earning capacity, its book value and financial condition, its dividend-paying capacity, whether it has goodwill or other intangible value, prior sales of its stock, and the prices of comparable businesses. That ruling was written for federal estate and gift tax valuation, but its logic — look at the whole business, not a shortcut — is how credentialed appraisers approach small-business value generally. In practice, three broad approaches get combined and weighed against each other.

Income approach: what future earnings are worth today

This approach asks what a buyer should pay today for the stream of profit the business is expected to produce going forward, adjusted for risk. The riskier and less predictable those future earnings look, the less a buyer should reasonably pay for each dollar of profit. This is the approach most small-business deals lean on most heavily, because it's the one that answers the question a buyer actually cares about: can this business pay for itself?

Market approach: what comparable businesses actually sold for

This approach looks at real, completed sales of similar businesses — similar size, similar industry, similar geography — and asks what buyers actually paid relative to their earnings. It's a reality check on the income approach: if your projections say one thing but nobody has been paying that much for a business like yours, the market approach is the one that wins the argument. Reliable comparable-sale data is not something you can pull off a free website; it's one of the things you're paying a credentialed appraiser or an experienced advisor in your industry to have access to and to interpret.

Asset approach: the floor, especially for a struggling business

This approach adds up what the business's tangible assets — equipment, inventory, receivables, sometimes real estate — would fetch, minus liabilities, largely ignoring what the business earns as a going concern. For a healthy, profitable business, this number is usually well below what the income or market approach produces, because it ignores the value of the customer relationships, trained staff, and reputation that make the business worth more running than sold off in pieces. But for a business that's losing money or has no real transferable earnings, the asset approach can become the realistic number — it's the floor a seller shouldn't expect to fall below, and sometimes the ceiling too.

How most small businesses actually get priced

In practice, most owner-operated small businesses are priced off a multiple applied to a normalized measure of annual earnings — commonly called seller's discretionary earnings (SDE) for a business where one owner works in it full time, or EBITDA (earnings before interest, taxes, depreciation, and amortization) for larger businesses with a management team in place that don't depend on one person showing up every day. The difference matters: SDE adds the owner's own compensation and perks back into earnings, because a buyer stepping into the owner's job gets that money; EBITDA does not, because the business already pays someone else to do the work.

This article deliberately does not state what multiple applies to your business. The right multiple depends heavily on your industry, your size, current lending and market conditions, and the specific risk factors below — a number pulled from an article or a website would be a guess dressed up as research, not a valuation. A credentialed business appraiser or an M&A advisor who knows your industry is the reliable source for that figure.

Normalizing the books: why add-backs matter

Before any multiple gets applied, a buyer or appraiser "normalizes" your financial statements — adjusting reported profit to reflect what the business would actually earn under new ownership, run at arm's length. Common, legitimate adjustments include:

• Owner's compensation. Replacing whatever salary or draws you took (which may be well above or below market) with what it would cost to pay a manager to do your job, and adjusting earnings by the difference.
• One-time or non-recurring items. A lawsuit settlement, a one-time equipment loss, a bad stretch caused by an event that won't repeat, or a startup cost the new owner won't incur again.
• Discretionary costs a new owner wouldn't carry. A vehicle, a professional membership, or a piece of the insurance bill that was properly reported but is tied to you rather than to the business's operations.
• Non-operating assets and expenses. Things on the books that aren't part of the business a buyer is buying.

Two honest cautions here. First, an add-back is a legitimate business expense that the new owner simply won't have — it is not a way to relabel a personal expense after the fact. Personal, living, and family expenses generally aren't deductible business expenses in the first place, and deducting them isn't an aggressive strategy so much as an inaccurate return, with real exposure if the IRS looks. If that's been happening, the conversation to have is with a CPA about getting it right going forward, not about how to present it to a buyer.

Second, the part owners tend to underestimate: a buyer's lender and appraiser will generally only credit an add-back that can be documented and defended. Anything they can't verify, or anything that looks like it understates how the business actually needs to be run, gets discounted or thrown out. And because a multiple gets applied on top, every dollar of earnings you can't prove is subtracted more than once from the price. Clean, well-documented books that an underwriter can verify are one of the highest-return investments an owner preparing to sell can make.

What moves a multiple, in either direction

Without stating numbers, these are the factors buyers, lenders, and appraisers weigh most heavily:

• Size. Larger, more established businesses with a longer track record are generally seen as less risky than very small ones.
• Growth trend. Consistent, well-documented growth is worth more than a flat or declining trend, even at similar current earnings.
• Recurring revenue. Contracts, subscriptions, or a base of repeat customers are more valuable than one-off, unpredictable sales.
• Owner dependence. A business that runs fine without you showing up every day — with trained staff, systems, and documented processes — is worth more than one that IS you.
• Customer concentration. A business where a handful of customers make up most of the revenue is riskier, and priced accordingly, than one with a broad customer base.
• Industry. Buyer demand, financing availability, and typical risk profiles vary a great deal by industry.
• Transferability. Licenses, key contracts, leases, and relationships that can actually transfer to a new owner support a higher value. This one catches people: many state and local business, professional, and trade licenses do not simply travel with the business — whether yours transfers, and what the buyer has to do to get their own, is a question for the specific state or local agency that issued it.

Be skeptical of online calculators and "revenue multiple" rules of thumb

Free online business valuation calculators and quick "your industry sells for X times revenue" rules of thumb are marketing tools, not appraisals — they generally exist to generate leads for the site offering them, and they cannot account for your specific normalized earnings, growth, customer concentration, or transferability. Note also that revenue rules of thumb ignore profitability entirely, which is the thing a buyer is actually buying. A formal business valuation is a real profession, performed by credentialed appraisers who follow recognized professional standards. For anything beyond a rough gut check — a sale, a partner buy-in, a divorce or estate matter, financing — that's the resource to use, not a free web form.

It's also worth knowing that the purpose of a valuation changes what it has to look like. A valuation prepared for a gift or estate tax filing, a divorce court, or an SBA lender may have to meet standards specific to that use, and a report written for one purpose won't necessarily be accepted for another. Tell the appraiser up front what the number is for.

The practical ceiling: what a buyer's lender will actually finance

Many small-business sales are financed at least in part, often through an SBA-guaranteed loan. Lenders making those loans underwrite the deal's cash flow themselves, and SBA's lender rules call for an independent business valuation from a qualified source in certain change-of-ownership situations — including larger financed amounts and deals between a buyer and seller who have a close relationship. The exact triggers and dollar thresholds live in SBA's lender operating procedures and are revised from time to time, so confirm the current rule with the lender or at sba.gov rather than relying on a number you read somewhere.

The practical effect is what matters to you: the price a lender is willing to finance — based on the business's demonstrated ability to service the debt and still support the new owner — becomes the real-world ceiling on what most buyers can actually pay, regardless of what a seller believes the business is worth. A price no lender will finance is a price with a very small pool of cash buyers.

What to do if you're getting ready to find out what your business is worth

1. Get clean, current financials first. A buyer's lender and appraiser will want at least a couple of years of tax returns and financial statements, plus current-year numbers, and they'll expect the returns and the statements to tell the same story.
2. Document your add-backs as you go, not the week before a sale — keep records that support any one-time or owner-specific expense you'll want added back.
3. Talk to a CPA about how your books currently look to an outside buyer and about the tax consequences of a sale, and to a business attorney about deal structure before you negotiate anything. How a deal is structured and how the price is allocated drives the tax bill, and that's worth understanding before you agree to a number.
4. Get a formal valuation or a broker's opinion of value from a credentialed professional rather than relying on an online estimate, especially before a real transaction, partner buy-in, divorce, or estate matter.
5. If you're selling equity, not just assets, remember that selling an ownership stake in your business is selling a security under federal law, with its own rules — get qualified legal advice before you structure it that way.

If the business is struggling rather than sellable at a profit, the asset-approach floor and your options around business debt and personal guarantees — including business bankruptcy — are a separate conversation from valuation, and worth having with a qualified attorney early rather than late. Remember that a personal guarantee follows you regardless of what the business is worth or what entity it's wrapped in.

Free help exists and it's genuinely useful at this stage: the U.S. Small Business Administration, SCORE, and your local Small Business Development Center can all talk through exit and valuation planning at no charge, and irs.gov is the place to confirm anything about the tax side of a sale.

Key takeaways

• Value comes from three approaches — income, market, and asset — weighed together, not one formula. The IRS's own valuation guidance says outright that no generally applicable formula exists.
• Most small businesses price off a multiple of normalized earnings (SDE or EBITDA), not raw revenue — and the right multiple is industry- and business-specific, not something an article can tell you.
• An add-back is a real expense a new owner won't have; personal expenses generally were never deductible, and unverifiable add-backs get discounted — costing you more, after a multiple, than the deduction ever saved.
• Online calculators and revenue-multiple rules of thumb are marketing, not appraisals.
• What a buyer's lender will finance is the real-world ceiling on price.

Frequently asked questions

Can I just use a revenue multiple everyone talks about in my industry?

Be careful with these. They're rough shorthand at best, they ignore your actual profitability, growth, and risk, and they're often used as marketing by sites trying to generate leads. A credentialed appraiser applies a multiple to your normalized earnings, not your top-line revenue, and adjusts it for your specific business.

Does my business have to be profitable to be worth anything?

Not necessarily to have some value — the asset approach can still put a floor under a struggling business based on what its equipment, inventory, and other assets would fetch, minus liabilities. But a business with no real earnings to sustain a buyer's debt payments will attract far fewer financeable buyers.

How far back should I clean up my books before I try to sell?

Start as early as you can — buyers and lenders typically want at least a couple of years of consistent, well-documented financials, and add-backs are much easier to defend when they're supported by contemporaneous records rather than reconstructed at the last minute. Ask a CPA how your specific books look to an outside buyer.

I've been running some personal costs through the business. Can I just add those back?

Only to the extent they were legitimate business expenses that a new owner genuinely won't have — that's what an add-back is. Truly personal expenses generally aren't deductible business expenses at all, so treating them as add-backs asks a lender to credit earnings your tax return says you didn't make. Talk to a CPA about correcting course before you go to market; it's a fixable problem and it's better fixed by you than found by an underwriter.

Is a free online business valuation calculator good enough for a real sale?

No. Those tools are useful only for the roughest of gut checks and are typically built to generate leads for the company offering them. For an actual sale, partner buy-in, or any transaction where the number matters, use a credentialed business appraiser.

What if a buyer's lender won't finance the price I want?

That's common, and it's a real signal, not just an obstacle. If no lender will finance a deal at your asking price based on the business's cash flow, the pool of buyers who can actually pay that price shrinks to all-cash buyers, which is a much smaller market. It's often worth revisiting your normalized earnings and add-back documentation with a professional before adjusting price expectations.
