This $600K Plumbing Works, But Doesn't Pay Enough
The numbers are mixed. Some things work, others need negotiation or restructuring.
This is a plumbing business listed at $600,000, generating $340,000 in annual revenue and $172,000 in seller's discretionary earnings. At a 3.49x cash flow multiple, the asking price sits above the industry average of 2.90x for plumbing businesses. The profit margin is 51%, above the 18% industry average.
We ran this deal through the DealScore Pro Bulletproof Calculator to see how it holds up across all five scoring criteria. Here is the full breakdown.
Deal Snapshot
The deal snapshot tells a mixed story. Revenue of $340,000 with a 51% margin means the business is generating real cash flow, not just top-line vanity. The 3.49x multiple is on the higher side relative to the industry average.
Financing Overview
Using the standard 80/10/10 SBA deal structure (80% SBA 7(a) loan, 10% seller financing, 10% buyer down payment), here is what this acquisition looks like when financed.
Why the Numbers Matter
The headline number most buyers fixate on is the asking price. But the asking price alone tells you almost nothing about whether a deal is worth doing. What matters is what happens after you finance it.
The post-debt cash flow of $80,358 per year is the real number. That is what you take home after every loan payment, every month, for the life of the loan. On a $60,000 cash investment, that is a modest return, and it is near the $100K minimum threshold that the Bulletproof standard requires.
The DSCR of 1.88x means the business generates $1.88 for every $1 of annual debt payment. SBA lenders require a minimum of 1.25x. The Bulletproof standard requires 2.0x. This deal clears the bank minimum but falls short of the Bulletproof target, leaving you with a thinner safety margin.
The stress test is where many deals that look good on paper fall apart. We model a 20% drop in revenue and check whether the business can still cover all debt obligations. This deal passes. Even at $272,000 in revenue (down from $340,000), the cash flow still services the debt. That is the kind of resilience you want in a financed acquisition.

Frequently Asked Questions
Is $600,000 a fair price for a plumbing business?
At 3.49x seller's discretionary earnings, this asking price is above the industry average multiple of 2.90x for plumbing businesses. Deals priced below 2.40x are generally considered favorable for buyers, while anything above 3.60x starts to look expensive.
What is a good profit margin for a plumbing business?
The industry average profit margin for plumbing businesses is approximately 18%. This listing operates at a 51% margin, which is above average and suggests the business is managing costs effectively. Margins above 13% are generally considered healthy in the plumbing industry.
Can I buy a plumbing business with an SBA loan?
Yes. Plumbing businesses are commonly financed through SBA 7(a) loans using an 80/10/10 structure: 80% SBA loan, 10% seller financing, and 10% buyer down payment. For this $600,000 deal, that means approximately $60,000 in cash at closing. SBA lenders require a minimum DSCR of 1.25x, but conservative buyers target 2.0x or higher. This deal's 1.88x DSCR clears the bank minimum but falls short of the conservative target.
How much do plumbing business owners actually make?
Owner earnings vary widely based on revenue, pricing, and operational involvement. This plumbing business generates $172,000 in seller's discretionary earnings (SDE) before debt service. After SBA financing under the 80/10/10 structure, the buyer would take home approximately $80,358 per year. That post-debt figure is the number that actually matters for a financed acquisition, because it reflects what ends up in your pocket after every loan payment is made.
