How Do You Value a Small Business?

Ask three advisors what your business is worth and you'll likely get three numbers. A valuation is an informed estimate, not a fixed fact, and the figure moves with your earnings, your industry, and why you're asking. Most small businesses, though, are valued the same core way: a multiple of their earnings, cross-checked against what similar businesses sold for.

This guide covers when you need a valuation, the three main methods, how earnings multiples actually work, what raises or lowers your number, and how to estimate it yourself.

When you need a business valuation

Selling is the obvious reason, but it's far from the only one. Knowing your number matters well before any sale.

You need a valuation when you're selling the business, buying one, or bringing in or buying out a partner. Lenders may want one for a loan, and you'll need it to issue equity to employees or investors. Life events, divorce, estate planning, or a partner's departure force the question too.

Even with no transaction in sight, a valuation sets a baseline you can track. Watching the number rise or fall year to year tells you whether the value you're building is actually growing, which ties directly to the finance metrics that matter most.

The three ways to value a business

Valuation methods fall into three families. Most valuations use more than one and cross-check them against each other.

For most profitable small businesses, the income approach leads, and the market approach checks it. Asset-based valuation matters most for businesses with heavy equipment or little profit, or one that's winding down.

Asset-based valuation reads straight off your balance sheet. The Investopedia guide to business valuation covers the wider set of methods, including discounted cash flow for larger companies.

SDE and EBITDA: how small businesses are actually valued

The income approach starts with an earnings figure, which depends on size. Two dominate small-business valuation.

Seller's Discretionary Earnings, or SDE, is used for smaller, owner-operated businesses. It starts with net profit and adds back the owner's salary, owner perks, interest, taxes, depreciation, and one-time expenses, showing the full financial benefit to a single owner-operator. It answers what the business really earns for the person running it.

EBITDA, earnings before interest, taxes, depreciation, and amortisation, is used for larger businesses with management in place. It strips out financing and accounting decisions to show core operating earnings.

The rough line is that smaller owner-run businesses are valued on SDE and larger ones on EBITDA, though the two overlap. Both build on your profit figures, so those need to be right.

The multiple: what it depends on

Once you have an earnings figure, you multiply it by a number that reflects risk and demand. That multiple is where most of the variation lives.

Multiples vary by industry, size, and market conditions. As a rough guide, small owner-operated businesses often sell for around 2 to 3 times SDE, while larger businesses valued on EBITDA command higher multiples, often 3 to 6 times or more.

These are starting points, not rules. A fast-growing software business and a local retail shop won't carry the same multiple even at identical earnings.

What pushes your multiple up is lower risk and higher growth. A business with steady, growing, recurring revenue and clean records earns a higher multiple than one with lumpy sales and messy books. This is why two businesses with identical earnings can be worth very different amounts.

What drives your business's value up or down?

The multiple isn't arbitrary. Specific, improvable factors move it, and knowing them lets you raise your value before a sale.

Value goes up with strong and growing profitability, recurring or contracted revenue, a diversified customer base, and a business that runs without the owner. It goes up further with clean, verifiable financial records that a buyer can trust.

Value goes down with owner dependence, where the business collapses if you step away, customer concentration in one or two big accounts, declining or erratic revenue, and books a buyer can't rely on. Owner dependence is the one small-business sellers underestimate most: a business that only works because of you is hard to sell for much.

A simple way to estimate your value

You can get a defensible ballpark yourself. Work in the order the professionals do.

Start with your earnings. Calculate your SDE by taking net profit and adding back your salary, personal perks run through the business, interest, taxes, depreciation, and any one-time costs. Say that comes to $200,000.

Apply an industry multiple. If similar businesses in your sector trade around 2.5 times SDE, that's roughly $500,000. Then cross-check against comparable sales – what businesses like yours actually sold for recently.

If comps cluster near that figure, you're in the right range. If they don't, the gap is worth investigating first. For a real transaction, a professional valuation or business broker refines this considerably.

Why clean books get you a higher valuation

Here's the lever most owners overlook until it's too late. Every valuation method runs on your financial records, and a buyer's confidence in those records directly affects what they'll pay.

When your books are clean, current, and verifiable, a buyer can confirm your earnings quickly and trusts the number. When they're messy, behind, or full of personal expenses tangled with business ones, the buyer discounts for risk or walks. Due diligence is where shaky books cost real money, either in a lower price or a dead deal.

This is why the best time to tidy your books is long before you sell. Finlens keeps categorisation and reconciliation current on top of your accounting system, so your financials always support a credible valuation.

If a sale is even a possibility down the road, sorting the books now, or running an accounting cleanup if they've slipped, protects the price you'll eventually get.

Conclusion

Valuing a small business comes down to earnings times a multiple, checked against what similar businesses sold for. Start from SDE for a smaller owner-run business or EBITDA for a larger one, apply a realistic industry multiple, and cross-check against comparable sales to keep the number honest.

The multiple, and therefore the value, is something you can influence. Reduce owner dependence, build recurring revenue, diversify your customers, and grow profit, and your business earns a higher multiple. Neglect those, and buyers price in the risk.

Underneath all of it sits your bookkeeping. A valuation is only as credible as the records behind it, so keep your books clean and current, treat the number as a range rather than a promise, and bring in a professional when a real transaction is on the line.

Frequently asked questions

How do you value a small business?

Most small businesses are valued using the income approach: calculate an earnings figure (SDE for smaller businesses, EBITDA for larger ones), multiply it by an industry multiple, then cross-check the result against what comparable businesses recently sold for. Asset-based valuation is used mainly for asset-heavy or low-profit businesses.

What is SDE in business valuation?

SDE, or Seller's Discretionary Earnings, is the total financial benefit a business provides to a single owner-operator. It's calculated by taking net profit and adding back the owner's salary, owner perks, interest, taxes, depreciation, and one-time expenses. SDE is the standard earnings figure for valuing smaller, owner-run businesses.

What is a typical valuation multiple for a small business?

Small owner-operated businesses often sell for roughly 2 to 3 times SDE, while larger businesses valued on EBITDA typically command 3 to 6 times or more. Multiples vary widely by industry, size, growth, and market conditions, so these are starting points rather than fixed figures.

What is the difference between SDE and EBITDA?

SDE adds the owner's salary and perks back into earnings, reflecting the benefit to a single owner-operator, and is used for smaller businesses. EBITDA does not add back owner compensation and is used for larger businesses with management in place. Which one applies depends mainly on the business's size.

What increases a business's valuation?

Strong and growing profitability, recurring or contracted revenue, a diversified customer base, a business that runs without the owner, and clean, verifiable financial records all raise valuation. Reducing owner dependence and customer concentration are among the most effective ways to increase what a buyer will pay.

When should I get my business valued?

Get a valuation when selling, buying, bringing in or buying out a partner, applying for financing, issuing equity, or facing an estate or divorce matter. Even without a transaction, a periodic valuation sets a baseline so you can track whether the value you're building is actually growing.

How do clean books affect valuation?

Clean, current, verifiable books let a buyer confirm your earnings and trust the valuation, which supports a higher price. Messy or unreliable records make buyers discount for risk during due diligence or abandon the deal. Tidying your books well before a sale directly protects your final price.

Do I need a professional to value my business?

You can estimate a ballpark yourself using SDE, an industry multiple, and comparable sales. But for a real transaction, financing, or a legal matter, a professional valuation or business broker provides a defensible number that accounts for factors a quick estimate misses. Use the DIY figure for planning and a professional for deals.
