"How much is my website worth?" is one of the first questions every site owner asks — usually right before selling, or right after wondering whether all those late nights building content were worth anything. The honest answer is simple to say and harder to pin down: a website is worth what a buyer will pay for it. And buyers, almost without exception, pay for profit. Not for traffic, not for design, not for how clever the domain name is — for the money the site reliably makes each month, and how likely that money is to keep coming. This guide explains the simple method behind our free calculator, works through one example in full, and shows what pushes a valuation up or down.
The simple method: monthly profit times a multiple
The method buyers actually use is called the profit multiple, and it fits in one line:
Website value = monthly net profit × multiple
Net profit means revenue minus all the costs of running the site: hosting, the domain, tools and subscriptions, content, advertising, payment fees, and anything else you spend to keep it going. A site that brings in $2,000 a month but spends $800 on costs is a $1,200-a-month site, and it is valued on the $1,200 — not the $2,000. Revenue alone misleads, because two sites with the same revenue can have very different costs. Always work from net profit, averaged over a few months so one unusually good or bad month does not distort the picture.
The multiple is where judgement lives. In general, websites change hands at roughly 20 to 40 times their monthly net profit. Our calculator uses three multiples, set by the site's revenue trend: 38x for a growing site, 28x for a stable site, and 18x for a declining site. A growing site earns a higher multiple because the buyer is paying for future earnings as well as today's; a declining site earns a lower one because the buyer is taking on the risk that earnings keep falling. The multiple is the single biggest lever in the whole calculation — moving from 18x to 38x more than doubles the value of the same profit.
Why the trend changes the multiple
Trend is the calculator's way of asking one question: is this site's income heading up, flat, or down? A growing site has rising revenue over recent months, which suggests the audience and the income are both expanding. Buyers pay extra for that momentum, which is why the growing multiple is the highest at 38x. A stable site earns roughly the same month after month — predictable, low-drama income, valued at 28x. A declining site is losing revenue, and a buyer has to believe they can turn it around, so it is valued at the lowest multiple, 18x. Be honest about your trend when you enter it: picking "growing" for a flat site does not make the site more valuable, it just makes the estimate wrong.
The age adjustment
Older sites get a small uplift on top of the multiple. The age factor starts at 0.85 for a brand-new site and rises by 0.03 for each year of age, up to a cap of 1.15. At 3 years old, the factor is 0.85 + (3 × 0.03) = ×0.94. The reason is track record: a site that has survived for years has a history a buyer can check, an established audience, and usually a backlink profile and a reputation that a new site has not built yet. But age alone does not create value. A ten-year-old site with no profit is still worth very little, and a two-year-old site earning well can be worth far more than a dormant ten-year-old one. Age adjusts the value; profit creates it.
Worked example: a stable site earning $1,200 a month
This is the same example our calculator comes pre-filled with: a site with 50,000 monthly visitors, $1,200 a month in net profit, 3 years old, with a stable revenue trend. Here is the calculation, step by step:
| Monthly visitors | 50,000 |
| Monthly net profit | $1,200 |
| Site age | 3 years |
| Revenue trend | Stable |
| Valuation multiple (Stable) | 28x |
| Site age factor (3 yrs) | ×0.94 |
| Mid-point value ($1,200 × 28 × 0.94) | $31,584 |
| Estimated range (±30%) | $22,109 – $41,059 |
Step 1: multiply the profit by the multiple. $1,200 × 28 = $33,600. Step 2: apply the age factor. $33,600 × 0.94 = $31,584 — the mid-point of the estimate. Step 3: widen it into a range of ±30%. $31,584 × 0.7 = $22,109 at the low end, and $31,584 × 1.3 = $41,059 at the high end. So the site is worth roughly $22,109 to $41,059, with $31,584 as the central figure.
What about the traffic? The 50,000 visitors are not what sets the price — the $1,200 of profit does. Traffic's job in the calculation is to support the profit: 50,000 visitors producing $1,200 a month is a plausible ratio, about 2.4 cents per visitor per month. The calculator also runs a sanity check behind the scenes: if the profit you enter looks unrealistically high for the traffic you report, it caps the profit used in the calculation, so that one typo cannot produce a fantasy number. Real buyers do the same check in their heads.
What the range means
The mid-point, $31,584 in our example, is the central estimate — the figure to quote when someone asks for a single number. The low end is roughly where a quick sale lands: a buyer who wants a bargain, or a site with risks a buyer can see. The high end is where a well-prepared sale lands: clean, documented books, diversified traffic, and a buyer who particularly wants your niche. The range is ±30% because no two buyers ever agree exactly on a price, and because a formula working from four numbers cannot see everything about a site. A range is more honest than a single figure pretending to be precise.
What pushes your value up — or down
Several things move a site toward the high end of its range. Diversified traffic is the biggest: visitors arriving from search, social media, direct visits and email, so that no single source can wipe out the audience overnight. Recurring revenue comes next — subscriptions or memberships beat one-off sales, because the income renews itself. Clean, documented books matter enormously: profit a buyer can verify from bank and payment records is worth more than profit you describe from memory. An email list, a recognisable brand, and a clear niche all help too.
The things that push value down are the mirror image. A site dependent on one traffic source — say, nearly all visitors from a single search engine — is one algorithm change away from trouble. Declining revenue, a site that only works because the owner personally does everything, messy or unverified books, and thin content that a buyer would have to rebuild all pull the value toward the low end. The good news is that most of these are fixable before a sale: diversify traffic, document income, and automate or delegate the daily work, and the same site can move from the low end of its range toward the high end.
What this estimate is not
An instant estimate is a starting point, not a formal valuation. It is calculated from four numbers you enter — traffic, profit, age and trend — and it cannot see anything else about your site. A human broker or marketplace valuation goes further: it checks traffic proof by looking at your analytics, revenue proof from bank and payment records, the niche your site sits in, and how much buyer demand there is for sites like yours right now. Those checks can move a price well away from the formula's answer, in either direction. Use the calculator's figure to set expectations and to negotiate — not as a guaranteed sale price. Our calculator page explains the difference between an instant estimate and a broker valuation in more detail.
How to use your number
If you are thinking of selling, the mid-point is a sensible place to start the conversation, and the range tells you how much room there is to negotiate. If a buyer's offer lands far below the low end, ask what risks they see that the formula missed; if it lands above the high end, take it seriously. If you are keeping the site, run the numbers every few months with the same honest inputs and watch the trend — a rising value means the work you are doing is compounding. And if you are thinking of buying a site, run the seller's figures through the same method: if the asking price sits far above the high end of the range, ask the seller to show the proof that justifies it. In every case, the value of the exercise is not the number itself — it is understanding which levers move it.
