Business Valuation Calculator

Most field service businesses sell for 2 to 5 times their annual earnings (SDE or EBITDA), with the exact multiple depending on size, profitability, recurring revenue, customer concentration, and growth. Smaller owner-operated businesses under $1M in revenue typically fetch 2–3× SDE, while larger, systematized businesses with recurring maintenance contracts and management in place command 4–6× EBITDA. A business earning $300,000 in adjusted profit at a 4× multiple is worth roughly $1.2 million.

Field service businesses typically sell for a multiple of 2× to 5× earnings, though high performers with strong recurring revenue can exceed that. The multiple rises with size, recurring revenue percentage, low customer concentration, documented systems, a management team that runs the business without the owner, and consistent year-over-year growth. Buyers pay premiums for businesses that will keep running profitably after the current owner leaves.

The most common method is the earnings-multiple approach: calculate normalized annual earnings (SDE for owner-operated businesses, EBITDA for larger ones), then multiply by an industry multiple of 2–5×. Add the value of tangible assets like vehicles and equipment, and adjust for recurring revenue, growth, and customer concentration. This calculator uses revenue, cost of sales, assets, and a valuation multiplier to produce that estimate.

SDE (Seller’s Discretionary Earnings) values smaller, owner-operated businesses — it’s profit plus the owner’s salary, benefits, and one-time or personal expenses added back, showing the total financial benefit to a single owner-operator. EBITDA (Earnings Before Interest, Taxes, Depreciation, and Amortization) is used for larger businesses run by management rather than the owner. The rule of thumb: businesses under about $1M in earnings are valued on SDE, larger ones on EBITDA.

The biggest value drivers are recurring revenue (maintenance agreements and service contracts), low customer concentration (no single client over ~10% of revenue), documented systems and processes, a management team that runs the business without the owner, consistent growth, clean financials, and a strong online reputation. Buyers pay more for a business that runs like a system than one that depends on the owner showing up every day.

Focus on the 1–3 years before a sale: build recurring revenue through maintenance agreements, clean up financials and separate personal expenses, reduce owner dependence by documenting processes and empowering a manager, diversify your customer base, invest in software and systems that prove the business is scalable, and show consistent year-over-year growth. Each of these can move your earnings multiple up by a full point or more — often worth far more than the effort.

Normalized (or adjusted) earnings restate your profit to show what a buyer would actually earn, by adding back owner-specific and one-time expenses — the owner’s above-market salary, personal vehicle or travel, one-time legal or equipment costs, and other non-recurring items. This reveals the business’s true earning power independent of how the current owner runs it. Valuations are almost always based on normalized earnings, not the raw net profit shown on a tax return.

Recurring revenue dramatically increases valuation because it’s predictable, transferable, and low-risk for a buyer. A field service business with 40% of revenue locked in through maintenance agreements can command a multiple a full point or two higher than an identical business doing only one-time work. Recurring contracts also smooth out seasonality and lower customer acquisition costs — all things buyers pay a premium for.

This calculator gives you a fast, ballpark estimate using standard multiples — useful for planning, goal-setting, and understanding where you stand. A formal valuation by a certified appraiser or business broker digs into normalized financials, market comparables, and deal structure, and is what you’ll need for an actual sale, financing, or legal matter. Use this calculator to track your value as you grow; when you’re ready to sell or raise capital, bring in a professional. Housecall Pro’s reporting and job costing help you build the clean financials and recurring revenue that drive a higher valuation in the first place.
