How do you estimate what a business is worth?
Start with three questions: what earnings can a new owner verify, what would comparable buyers pay for those earnings, and what assets or liabilities transfer? An estimate is a range, not a guaranteed selling price. An independent appraiser may be needed for financing, tax, or legal purposes.
Step 1: calculate normalized earnings
For an owner-operated business, start with reported net income and reconcile it to tax returns and bank records. Add one working owner's compensation and benefits, interest, taxes, depreciation, amortization and documented expenses that truly will not recur. This produces seller's discretionary earnings (SDE), sometimes marketed as owner's cash flow. Do not add back ordinary operating expenses that the buyer must still pay.
For a business run by paid management, EBITDA may be a better comparison. Keep a reasonable manager's wage in the expenses. Never apply an EBITDA multiple to an SDE figure: the measures account for owner pay differently.
Step 2: apply a comparable earnings multiple
Estimated operating value = normalized annual earnings × an appropriate multiple. For illustration only, $200,000 of verified SDE at 2.5× to 3.5× gives a $500,000–$700,000 operating-value range. These example multiples are assumptions, not market quotes for a particular industry. Check recent comparable transactions using the same earnings definition, deal size, location and included assets.
Recurring contracts, diversified customers, transferable systems and stable growth can support a higher multiple. Owner dependency, expiring leases, concentrated customers and disputed add-backs can justify a lower one. Ask what would still be true a year after the seller leaves.
Step 3: reconcile assets, liabilities and deal terms
List equipment, inventory, receivables, real estate, cash and debt separately. Confirm what is included in the quoted price. Do not simply add ordinary equipment already needed to produce the earnings on top of an earnings-based value; that can count it twice. Separately priced excess assets or property may change the final price. Subtract liabilities only when the buyer assumes them or when calculating equity value from enterprise value.
Finally test whether earnings after a reasonable owner or manager salary, replacement spending, taxes and financing costs support the purchase. A $600,000 valuation does not mean $600,000 is affordable to a buyer. The WhatBiz estimator provides an educational range, not a certified appraisal.
Frequently asked questions
- Does inventory get added to the valuation?
- Often yes for asset-heavy businesses, but it should be stated explicitly. Whether inventory is inside or outside the asking price is a frequent point of negotiation.
- Is a formal appraisal necessary?
- A lender, court, tax authority or transaction may require a qualified independent valuation. An educational range is useful for early screening, but check the specific requirement with your lender and advisers.
