How long until a bought site pays for itself?

Buy a business for $24,000 that earns $12,000 a year and you have paid 2× annual profit. Hold it for two years at that rate of earnings and you have your $24,000 back. The multiple is the payback period, measured in years, and the conversion is nothing more than reading the same fraction the other way up: price over annual profit, in years; times twelve, in months.

Two conditions are doing quiet work in that sentence, and the rest of this page is about them. The profit figure has to be real, and it has to keep happening. Neither is a safe assumption in this market, which is exactly why the payback framing is useful — it converts a benchmark you cannot argue with into a prediction you can.

The payback column is arithmetic, not a forecast: it is the median multiple times twelve months, and it describes what the price implies if stated profit is accurate and continues unchanged. Where fewer than five sales support a median we publish no multiple, and so no payback either. These medians are taken over every sale of that type we hold that carries a usable profit multiple — no recency window and no outlier trim — which is a wider population than the one behind the sold-price ranges on what small online businesses actually sell for. Compare within a table, not across the two.

Every effect that separates the implied figure from a real one pushes the same way — later, never sooner. Four are worth pricing in before you make an offer:

• The profit figure is a claim. Our comps carry what listings stated, and so does the listing in front of you. If stated profit is 30% optimistic, the payback is 30% longer than the multiple implies, before anything else happens.
• Earnings decay after a handover. Rankings, ad accounts, app store position and the previous owner's routine do not transfer intact. A site that earns the same in month twelve as it did in month zero is doing well, not doing normally.
• Your own time is not in the number. Trailing profit on a small listing is usually stated before any wage for the owner's work. If running it takes five hours a week that you would otherwise bill for, that cost belongs in the payback calculation and is almost never in the multiple.
• The purchase price is not the whole outlay. Migration, escrow fees, rebuilding whatever did not transfer and the first fix after something breaks all land before the first dollar of return does.

None of that makes small acquisitions a bad trade. It means the honest way to use the table above is as a boundary: whatever the median implies, your realistic payback is longer, and the gap between the two is the part of the deal you actually control.

Some of the medians in the table imply a payback well under a year — in places, a few months. Read that as a warning rather than an opportunity. A market that routinely prices businesses below one year of their own stated profit is a market discounting the statement, not one handing out free money to whoever shows up.

When you meet a single listing whose implied payback looks extraordinary, the profit figure is the thing to doubt first, not your luck. The usual explanations, in the order they turn up: the profit is annualised from one unusually good month; it is revenue with the costs left out; it includes income that does not transfer with the sale; or the asset is in decline and the trailing year flatters where it is now. Our own guide to what a profit multiple actually means covers how to read a median below 1×, and revenue multiple vs profit multiple covers the case where the denominator is not what it says it is.
