A website builder subscription runs about $10 to $50 a month. Plenty of agencies will tell you a custom build starts under $10,000. Both of those figures are true, and neither tells you what you are going to pay. The real average cost of a professionally built custom site is closer to $66,500, with a monthly retainer near $7,100 once the thing has launched and needs looking after. That gap, between the number in the ad and the number in the invoice, is the honest answer to how much does a website cost. It depends entirely on which of those two things you are buying, and most people do not find out which one until the quote arrives.
The cheap number prices a template. Someone drops your logo and copy into an existing layout, connects hosting, and you are live inside a week. The expensive number prices a decision: a site built around your business instead of the other way round, with a designer and a developer thinking through your customer, not a theme's customer. A website builder gives you a shell that a thousand other businesses are renting this same month. A custom build gets you one nobody else has. Whether that difference is worth $66,000 depends on what your business needs the site to do, not on which option sounds more responsible.
What moves the price is not the number of pages, it is the number of things the site has to do. A content management system, a shopping cart, order tracking, a login area, search, a chatbot: each one adds real engineering, not decoration. A five page brochure site and a five page site with a working checkout are not the same project, even though a client comparing quotes often assumes they are. The businesses that end up near that $66,000 average almost always have a product catalogue, an account system, or some other piece of real functionality behind the homepage. Not just more pages than a builder template allows.
Hourly rates run from under $25 an hour offshore to $200 or more at a senior studio, with most established shops in the US, Canada or Australia sitting around $100 to $149. A lower rate is not automatically the cheaper project. A team that takes three times as long at a third of the rate has billed you the same amount, and cost you two extra months getting there. The rate on the quote is not the number worth comparing. The total hours, and what the studio has shipped before, are.
The cost that catches people out is not the build, it is what comes after. A template's monthly fee is flat and it has a ceiling: you know exactly what you are paying and exactly what it will never become. A custom build's ongoing cost, that $7,100 a month average for care and small changes, is open ended, and so is what the site can grow into. One of those is a fixed expense. The other is closer to hiring a small team. Neither is the wrong choice, but only one of them is being sold to most people as if it were the other.
The honest question to ask before choosing either is whether you are shipping a fixed offer that will look the same in three years, or building something that needs to keep growing alongside the business. If it is the second one, ask a studio what the $66,000 actually buys before you compare it to a $30 a month subscription. The number means nothing without knowing what stops it from being enough in a year.
