SDE First, Then the Multiple

A simplified SDE valuation starts with your Seller’s Discretionary Earnings (SDE) and applies a multiple that reflects the quality, predictability, and transferability of those earnings. 

SDE is intended to represent the economic benefit available to an owner-operator. It starts with net profit and adds back owner compensation, owner perks, interest, depreciation and amortization, and eligible one-time costs.

The multiple reflects the quality and predictability of those earnings. Recurring maintenance agreements, lower owner dependence, and clean financial records can support a stronger multiple. HVAC businesses can also benefit from essential service demand and recurring maintenance revenue.

How To Value a HVAC Business

Use the calculator above, or run it yourself. For many smaller owner-operated businesses, buyers commonly use SDE as the earnings measure and apply a market-based multiple. Get these steps right.

  1. 1. Start with net profit. Pre-tax, from a clean P&L.
  2. 2. Add back owner compensation. Salary and draws a buyer will replace.
  3. 3. Add back eligible owner perks. Personal expenses such as vehicle, insurance, or travel run through the business may be added back when appropriate.
  4. 4. Add back eligible interest, D&A, and one-time costs. Include applicable financing costs, non-cash expenses, and qualifying non-recurring expenses.
  5. 5. That's your SDE the earnings measure used in this calculator.
  6. 6. Apply an HVAC multiple. Choose a multiple based on recurring service revenue, owner dependence, financial quality, customer concentration, and other business factors.

1.

Net profit

Your pre-tax bottom line and the starting point for calculating SDE.

2.

Owner compensation

Eligible owner compensation that may be added back when calculating SDE, depending on the valuation methodology.

3.

Owner perks

Eligible personal expenses such as a vehicle, insurance, or travel run through the business.

4.

Financing costs and non-cash accounting expenses added back to determine SDE.

5.

Frequently Asked Questions

SDE, or Seller's Discretionary Earnings, is net profit plus eligible expenses and benefits that a new owner would not inherit, such as owner compensation, certain personal expenses, interest, depreciation, amortization, and one-time costs. Buyers use SDE because it shows the economic benefit available to an owner-operator. Net profit alone does not provide the same comparison because it includes the current owner's compensation and other expenses that may change after a sale.
For many owner-operated businesses under roughly $3M in revenue, SDE is commonly used because the buyer may be taking over the owner's operating role. At larger businesses with an established management team, buyers may use EBITDA because those management costs continue after the sale. The crossover is not rigid, and the appropriate earnings measure depends on the business and buyer. This calculator uses the SDE method.
