How to determine what your business is worth

How to determine what your business is worth starts with a question about what a buyer receives and what the operation can earn under new ownership. Revenue alone cannot answer it. You need a consistent earnings measure, evidence for adjustments and a clear account of assets and obligations. This guide explains SDE and EBITDA, shows how earnings based formulas work without invented figures and connects an estimated range to the terms of a potential sale.

Business value depends on what changes hands

An owner may mean the value of the operating business, the value of ownership interests or the cash left after completing a sale. Those are different questions. Start by listing the assets and rights included in the proposed transaction. Consider equipment, inventory, customer contracts, intellectual property and property arrangements. Identify obligations that remain with the seller or need settlement at closing.

Write the valuation purpose beside that list. An estimate for sale preparation differs from a formal appraisal required for another purpose. A buyer also considers the work, risk and investment that follow the acquisition. Knowing your preferred price is useful, but the supporting analysis must address the earnings and transfer conditions a purchaser can actually evaluate.

Establish a consistent financial starting point

Use financial statements that reconcile with underlying records and explain material differences from tax reporting. Keep revenue and earnings on the same reporting basis and period. Review current trading alongside historical performance so temporary changes do not disappear inside an annual total. Document seasonality, unusual customer activity and expenses that move between periods. A clear starting point makes later adjustments easier to test.

Separate revenue from profit and profit from cash. Revenue describes sales before operating expenses. Accounting profit reflects the expenses recognized under the accounting approach used. Cash movements also reflect collection timing, borrowing, investment and other items. A valuation based on earnings therefore needs further work before anyone treats the result as money available to spend or distribute.

Seller's discretionary earnings explain an active owner role

Seller's discretionary earnings, usually called SDE, is commonly used when a purchaser expects to replace an owner who works in the business. It brings eligible owner compensation and documented adjustments into an earnings measure for that ownership model. The exact reconciliation matters because sellers may use the label differently. Ask what is included rather than accepting a headline SDE figure without its supporting schedule.

In words, a common starting reconciliation is SDE equals net income plus interest expense plus income tax expense plus depreciation plus amortization plus the compensation and benefits of the working owner being replaced, plus justified discretionary or nonrecurring expenses, minus nonrecurring income. Each item must start from the actual accounts. An expense already excluded from net income cannot be added again.

The owner role is essential to interpretation. SDE does not mean the business pays an investor that amount while a separate manager does all the work. If a purchaser needs management help, the cost reduces what remains for that purchaser. Where several owners work in the operation, identify their duties and retain the cost of the roles that still need coverage.

EBITDA uses a different treatment of management costs

EBITDA means earnings before interest, taxes, depreciation and amortization. In words, EBITDA equals net income plus interest expense plus income tax expense plus depreciation plus amortization, assuming those items are deducted in the starting net income. Operating payroll and necessary management expenses remain part of the cost base. EBITDA therefore does not automatically add back an owner's salary or benefits.

Adjusted EBITDA adds a further layer of proposed normalization. An owner salary may differ from the cost of replacing the actual work, so a defensible adjustment must preserve an appropriate cost for that role. Nonrecurring items need evidence too. Label adjusted and unadjusted figures clearly, reconcile them and explain why each change reflects the earnings a buyer can reasonably examine.

EBITDA is not operating cash flow or cash available after debt payments. It excludes items that can still require real spending, including taxes and investment in equipment. Working capital changes also affect cash. A buyer comparing opportunities needs to inspect those needs even when both sellers present the same earnings label.

Check whether each earnings adjustment survives a sale

Ask what changes after ownership transfers. A personal expense may qualify for review if it is recorded, identifiable and unnecessary for continued operations. A maintenance bill does not become removable just because the seller calls it unusual. Equipment still needs maintenance. An expense that does not recur in the same form may have a replacement cost that belongs in the buyer's forecast.

Consider income adjustments with equal care. An isolated receipt may overstate ongoing earnings, while a lost customer can weaken the case for using historical results unchanged. Keep the original result, proposed adjustment and supporting explanation together. The purpose is to make the analysis traceable, including adjustments that reduce earnings, rather than building the largest possible earnings figure.

Apply an earnings multiple to the matching earnings basis

An earnings based estimate can be expressed without assigning any invented amounts. Let S represent supported SDE and let M represent an applicable SDE multiple. Indicated operating value equals S multiplied by M. If the supported multiple range runs from L to H, the indicated range runs from S multiplied by L to S multiplied by H.

For an EBITDA approach, let E represent supported EBITDA and let N represent an applicable EBITDA multiple. Indicated operating value equals E multiplied by N. The definitions of E and N must match the comparison evidence. Do not use an SDE figure with an EBITDA multiple or assume the ranges are interchangeable. The output remains an estimate whose transaction assumptions need definition.

Use the business valuation calculator to see the applicable range and method for the details you enter. Multiples depend on industry, size and years in business. The calculator shows its range rather than establishing a universal multiple for every firm in an industry. Keep a copy of the earnings basis so you can explain changes when an input changes.

Read the valuation range alongside operating risk

A buyer examines whether earnings continue after closing. Customer concentration, dependence on a particular supplier, recurring contract terms and the owner's personal relationships all affect that question. Look at how revenue is earned and collected, whether employees hold essential knowledge and whether the business can retain the capabilities that create its profit. An earnings total alone does not reveal those dependencies.

Review investment needs and rights to operate. Worn equipment, deferred improvements and a short remaining lease can change the resources required after acquisition. Contracts and licenses may need consent or other steps before transfer. Avoid applying an arbitrary adjustment for each concern. Gather evidence and discuss how the concern changes earnings expectations, required spending or the proposed purchase terms.

Separate operating value from the owner's sale proceeds

An operating value estimate does not tell you what reaches your bank account. Debt, retained cash, working capital, inventory and excluded assets need agreed treatment. Read the business enterprise value formula to understand the conceptual bridge between enterprise value and equity value. An asset purchase can use different contractual mechanics from a transfer of ownership interests.

Costs, taxes, deferred payments and amounts held back under the agreement can change the timing and amount received. A conditional payment should not be treated as cash already paid. Ask your advisers to map the proposed terms to a closing statement and explain the later obligations. This step helps you compare offers that use the same headline price but deliver different outcomes.

Use your estimate to prepare better sale questions

Bring together the financial statements, adjustment schedule, description of owner duties and sale perimeter. Identify which assumptions have documentary support and which need review. If an estimate changes sharply when you remove a disputed adjustment, resolve that issue before relying on the higher result in a listing. You can also read how do you sell a business for the wider preparation process.
