Every partner buyout starts with the same question — and the same argument: what is this business actually worth?
The departing partner thinks it's worth more. The staying partners think it's worth less. Both have financial incentives to be right. Without a pre-agreed method, the valuation becomes a negotiation — and negotiations under pressure (death, disability, divorce, disputes) rarely produce fair outcomes.
This guide covers the valuation methods available, when each one works best, and why having a method agreed upon before a buyout is triggered changes everything.
Why Valuation Matters for Buyouts
The valuation determines how much money changes hands. Get it wrong and one side gets cheated:
- Undervalued: The departing owner (or their estate) receives less than their share is worth. They're subsidizing the staying owners' continued ownership.
- Overvalued: The staying owners pay more than the business is worth. They're starting their continued ownership underwater, potentially taking on debt they can't service.
The goal is fair market value — the price a willing buyer would pay a willing seller, with both parties having reasonable knowledge of the relevant facts, and neither under compulsion to act.
That's the textbook definition. In practice, achieving it requires choosing the right method for your business type and situation.
The Five Valuation Methods
1. Multiple of Earnings (Most Common)
Formula: Business Value = Annual Earnings x Industry Multiple
The most widely used method for profitable small and mid-sized businesses. "Earnings" is typically EBITDA (Earnings Before Interest, Taxes, Depreciation, and Amortization) or SDE (Seller's Discretionary Earnings, which adds back the owner's salary and benefits).
Typical Multiples by Industry
| Industry | Typical EBITDA Multiple |
|---|---|
| Professional services (law, accounting, consulting) | 2-5x |
| Medical practices | 3-6x |
| Technology / SaaS | 5-12x |
| Manufacturing | 3-6x |
| Retail / E-commerce | 2-4x |
| Construction / Trades | 2-4x |
When it works best: Businesses with consistent, demonstrable earnings over 3+ years. The multiple reflects the industry, growth rate, client concentration, and how dependent the business is on the departing owner.
When it doesn't work: Businesses that aren't yet profitable, businesses with highly volatile earnings, or businesses where the departing owner IS the entire revenue stream (the multiple should be lower if the business can't generate the same earnings without them).
2. Multiple of Revenue
Formula: Business Value = Annual Revenue x Revenue Multiple
Used when the business is growing but not yet profitable, or when earnings don't reflect the business's true value (common in high-growth companies investing heavily in expansion).
Typical multiples: 0.5-2x revenue for most small businesses. Higher for recurring revenue models (subscriptions, retainers) than for project-based or transactional revenue.
When it works best: Early-stage businesses, high-growth companies, businesses with strong recurring revenue. Also useful as a sanity check against earnings-based valuations.
3. Asset-Based (Book Value)
Formula: Business Value = Total Assets - Total Liabilities
Calculates what the business owns minus what it owes. Best for businesses whose value is primarily in physical assets — real estate, equipment, inventory — rather than in earnings, relationships, or intellectual property.
When it works best: Manufacturing, real estate, asset-heavy businesses. Also used as a "floor" valuation — the business is worth at least this much even if earnings drop to zero.
When it doesn't work: Service businesses, professional practices, technology companies — anywhere the value is in people, relationships, and intellectual capital rather than physical assets.
4. Discounted Cash Flow (DCF)
Formula: Business Value = Sum of projected future cash flows, each discounted to present value
The most theoretically rigorous method. Projects the business's future cash flows and discounts them back to present value using a rate that reflects the risk of those projections materializing.
When it works best: Businesses with predictable, growing cash flows and a long track record. Most meaningful for larger businesses where the projections can be based on substantial historical data.
When it doesn't work: Small businesses with volatile cash flows, businesses highly dependent on one person (the projections change dramatically depending on who leaves), or any situation where the future is too uncertain to project reliably.
5. Professional Appraisal
Not a method per se — it's hiring a certified business appraiser (often a CVA or ASA credentialed professional) to determine fair market value using multiple methods, weighted for your specific situation.
Cost: $5,000-$25,000+ depending on business complexity.
Timeline: 30-90 days.
When it works best: High-value buyouts ($500K+), contested valuations, estate settlements, IRS compliance, and any situation where the stakes justify the cost and both parties need an independent opinion.
Use a formula (earnings multiple or revenue multiple) as the primary method, agreed upon in your buy-sell agreement. Include a professional appraisal as the dispute resolution mechanism — if either party disagrees with the formula result, they can request a formal appraisal at shared cost. This gives you speed (formula calculates instantly) with a fairness backstop (appraisal available if needed).
Valuation Adjustments for Buyouts
Raw business value is the starting point, not the final number. Several adjustments may apply:
Minority Discount
A 30% owner's share is not simply 30% of the total business value. Minority ownership has less control, less liquidity, and fewer rights than majority ownership. A discount of 15-30% is common for minority interests. Your buy-sell agreement should specify whether minority discounts apply.
Lack of Marketability Discount
Shares in a private business can't be sold on an exchange. They're illiquid. This reduces their value compared to equivalent shares in a public company. Discounts of 10-25% are common. Again, your buy-sell agreement should address this.
Key Person Discount
If the departing owner IS the business — the primary rainmaker, the sole technical expert, the face of the brand — the business may be worth less without them. A key person discount reflects the reality that future earnings projections must be adjusted downward when the key person is gone.
This is one of the most contentious adjustments. The departing owner's estate argues the business is worth what it was worth with the owner alive. The staying partners argue it's worth what it will be worth going forward. Key man insurance solves this by providing capital to bridge the gap.
Control Premium
The inverse of the minority discount. If the buyout results in one remaining owner gaining majority or full control, that control is more valuable. The premium is typically built into the purchase price for the controlling interest.
Valuation by Buyout Trigger
| Trigger | Valuation Considerations | Recommended Approach |
|---|---|---|
| Death | Must be fair to the estate. No time for extended negotiation. IRS may scrutinize for estate tax purposes. | Pre-agreed formula in buy-sell agreement. Professional appraisal as backstop if estate disputes. |
| Retirement | Planned departure with time to negotiate. Departing owner wants maximum value. Staying owners want to pay minimum. | Formula as starting point, professional appraisal if needed, installment payment structure. |
| Disability | Similar to death — urgent, not negotiable under ideal conditions. May need to account for reduced business value due to the disability. | Pre-agreed formula. Disability buyout insurance to fund it. |
| Disagreement | Both parties motivated but adversarial. Risk of lowball offers or inflated demands. | Independent appraisal. Mediation if needed. Buy-sell agreement terms if they exist. |
| Divorce | Court may order its own appraisal. Spouse's attorney will push for highest possible value. | Independent appraisal by court-accepted appraiser. Buy-sell agreement terms may or may not be honored by the court. |
The Pre-Agreed Valuation: Why It Changes Everything
The single most important thing you can do for buyout valuation is agree on the method before you need it.
A buy-sell agreement that specifies the valuation method — updated annually — eliminates the negotiation entirely. When a triggering event occurs:
- The formula runs
- The number is calculated
- The funding mechanism provides the cash
- The buyout executes
No arguments. No attorneys. No 6-month negotiation while the business suffers.
The Annual Update Requirement
A pre-agreed valuation only works if it's current. If you agreed the business was worth $1 million in 2020 and it's now worth $3 million, the 2020 number is useless — and potentially fraudulent if used for an estate settlement.
Build an annual valuation review into your business calendar. Update the formula inputs (revenue, earnings, assets). Adjust insurance coverage amounts to match the new valuation. This takes 1-2 hours per year and prevents the most common buy-sell agreement failure: outdated valuations.
