Can This Business Replace Your Salary?

You are earning $200,000 a year. You find a residential HVAC business listed at $1.6 million. The broker summary says the seller's discretionary earnings are $425,000. You run the division in your head: $425K minus some debt payments, and it looks like the salary is covered.

This back-of-napkin version is how most buyers start. It is also where most buyers fool themselves. The gap between SDE on a broker summary and cash you can actually take home is wider than it appears, and understanding that gap is the difference between a deal that works and one that quietly traps you.

Start with what SDE actually means

Seller's discretionary earnings is the business's profit after all operating expenses, restated to add back the owner's salary, benefits, and discretionary spending. It represents the total economic benefit available to a single owner-operator.

The number on the broker summary is a starting point, not a fact. A quality of earnings review will typically adjust it — sometimes up, sometimes significantly down. For this walkthrough, assume SDE has been validated at $425,000 after adjustments.

That $425K is not your salary. It is a pool of cash that has to cover four obligations before you see a dollar of personal income.

The four claims on SDE

1. Debt service

An SBA 7(a) loan on a $1.6M acquisition at 15% down means you are borrowing $1.36 million. At current SBA rates (Prime + 2.75%, roughly 10.25% as of early 2026), the annual debt service on a 10-year term is approximately $217,000.

This is the largest claim on SDE, and it is non-negotiable. Miss a payment and the lender has a lien on every business asset and your personal guarantee covers the rest.

2. Working capital reserve

The business needs cash on hand to operate: payroll, parts, insurance premiums, seasonal swings. Most service businesses need 2-3 months of operating expenses in reserve. For a business doing $1.8M in revenue with ~75% operating costs, that is roughly $60,000-$90,000 you need to keep accessible.

In Year 1, you may be building this reserve from scratch if the seller took it as part of the transaction. Budget $75,000 for the reserve, drawn from cash flow over the first 12 months. In subsequent years, the reserve is maintained, not rebuilt, so this line item drops significantly.

3. Capital expenditures

Service businesses need equipment: trucks, tools, HVAC units in inventory, fleet maintenance. The seller's SDE number often defers or minimizes capex because they were winding down, not investing. You are in growth mode (or at minimum, maintenance mode) and need to budget for it.

For a residential HVAC business, $30,000-$50,000 per year in capex is reasonable. Call it $40,000. Some years will be higher (replacing a truck), some lower. The mistake is budgeting zero.

4. Taxes

Your owner compensation is taxed as ordinary income. Self-employment taxes apply to the pass-through entity income. Depending on your structure (S-corp is common post-acquisition), effective tax rates on owner compensation land between 30-38% for this income range. The tax impact is on whatever you pay yourself, so we will apply it at the end.

Running the numbers

That $62,000 after-tax take-home is not $200,000. It is not close. And this is a business with $425K in SDE, a strong, healthy business by any measure.

Year 2 and beyond: where the math changes

Year 1 is an outlier. Here is why:

• Working capital reserve is built. That $75K line item drops to $0 in Year 2 (assuming stable or growing revenue).
• Revenue growth compounds. Even modest 5-8% organic growth in a well-run service business adds $25,000-$35,000 in incremental SDE.
• Operational improvements. Most acquisitions produce 5-15% efficiency gains in the first 18 months through route optimization, pricing adjustments, and marketing spend reallocation. Call it $20,000-$40,000 in additional margin.

$143,000 is not $200,000. But it is within range, and the trajectory is clear. By Year 3, with continued modest growth, pre-tax owner compensation approaches $250,000. After tax, you are at or above your prior salary.

The variables that move the answer

This framework is a baseline. Several factors shift the outcome in either direction:

Down payment size. A 20% down payment ($320K) reduces the loan to $1.28M and annual debt service to ~$204K. That is $13,000 more cash per year. A 10% down payment (if the lender allows it, often with a seller note) increases debt service by roughly the same amount. More equity in means less strain on cash flow.

Seller note. If the seller carries 10% as a subordinated note at 6% interest-only for two years, your Year 1 cash position improves by $8,000-$12,000 depending on structure. Seller notes also signal the seller's confidence in the business. That is useful information on its own.

SDE quality. A $425K SDE with $50K in addbacks for "owner's personal travel" is not the same as a $425K SDE built entirely from operating income. Scrutinize the addbacks. Every dollar of questionable SDE is a dollar you may not actually receive.

Revenue concentration. If 30% of revenue comes from two clients, your SDE is fragile. Salary replacement math assumes the SDE persists. Customer concentration risk means it might not.

Your spouse's income. Most first-time buyers in this demographic are in dual-income households. If your partner earns $100K-$150K, the Year 1 cash gap is a lifestyle adjustment, not a crisis. This is the most common bridge, and the reason search timelines extend to 19 months on average. People wait until they feel financially secure enough to absorb Year 1.

The question most buyers actually need to answer

The real question is not "can this business replace my salary in Month 1." It almost never does — and that is fine.

The real question is: can I absorb 12-18 months of reduced personal income while the math improves?

That question has three components:

1. Cash reserves. After your down payment and closing costs, do you have 6-12 months of personal living expenses accessible? Most lenders will want to see this anyway.
2. Household income. If a partner is working, the gap is manageable. If you are single-income, the math is tighter and the reserve needs to be larger.
3. Lifestyle flexibility. The buyer who can temporarily reduce personal spending from $15K/month to $10K/month has a wider margin than the buyer who cannot.

Buyers who model these three factors accurately almost always find a path. Buyers who skip them and stare at Year 1 take-home versus current salary talk themselves out of good deals.

Framework summary

Once a listing passes your initial screen, run this sequence to evaluate salary replacement:

1. Start with validated SDE, after QoE adjustments, not the broker summary number.
2. Subtract debt service based on actual SBA terms, not rough estimates.
3. Subtract a Year 1 working capital build (2-3 months of operating expenses).
4. Subtract a capex reserve appropriate to the industry.
5. Apply your effective tax rate to whatever remains.
6. Compare the result to your minimum household income requirement, not your current salary.
7. Model Year 2 and Year 3 with conservative growth assumptions.

If Year 1 is survivable and Year 2-3 puts you at or above your prior income, the math works. If Year 1 requires draining reserves you cannot rebuild, the deal is too tight. Either the price is wrong, the business is too small, or the timing is not right.

The salary replacement question has an answer. It just requires more line items than most buyers account for.
