Is the Asking Price Fair? A Buyer's Guide to Checking a Listing

Flip the formula

Our valuation calculator runs one direction — SDE × industry multiple = estimated sale price. A listing you’re actually looking at already has a price attached, so the useful move is to run the formula backward: divide the asking price by the seller’s stated SDE to find the implied multiple the listing is actually asking you to pay. That single number is directly comparable to the published industry average, in a way the raw asking price alone never is.

Compare against the published average

Once you have the implied multiple, look up the industry’s average from BizBuySell’s published sold-business data and see where the listing sits relative to it. A listing implying 3.2× in an industry that averages 2.2× is asking you to pay roughly 45% more per dollar of earnings than the typical completed sale in that industry — a fact worth understanding before you make an offer, whichever direction you end up going.

The “in line” band is a framing choice, not a data point

Our checker labels a listing “in line” when its implied multiple sits within 10% of the published average. That band is our own presentational convention, not part of BizBuySell’s source data — we say so on the page for exactly this reason. Treat it as a rough sorting line between “close enough to the average that the difference is probably noise” and “far enough to be worth asking why,” not as a pass/fail verdict on the deal.

When a listing runs well above average

A high implied multiple isn’t automatically a red flag. It can reflect real strength — a long operating history, a secure lease, diversified customers, clean books — the same qualitative factors our valuation calculator prices explicitly. But it can also reflect seller optimism, inflated add-backs that won’t survive diligence, or a broker pricing to a seller’s hopes rather than the market. The implied multiple tells you that the price is elevated; it doesn’t tell you why — that’s what diligence on the underlying SDE add-backs is for.

When a listing runs well below average

A low implied multiple can be a genuine bargain — an underpriced or under-marketed business, or a motivated seller. It can also signal something not yet visible in the topline numbers: a declining revenue trend, concentrated customers, deferred maintenance, or a short lease. A below-average multiple is a reason to look closer, not a reason to assume you’ve found free money.

A revenue-multiple cross-check

When you don’t fully trust the seller’s stated SDE — add-backs are unverified, or the books are thin — the published revenue multiple is a useful second signal. Divide the asking price by gross revenue and compare that to the industry’s average revenue multiple. If the SDE-implied multiple and the revenue-implied multiple tell noticeably different stories, that gap is itself information: it usually means the seller’s claimed margin is unusually high or low relative to the industry norm, which is worth verifying before you rely on either number.

Enter a listing’s asking price, SDE, revenue, and industry into the Asking Price Checker to see both the implied multiple and the published average side by side.
