A landing page usually costs less than a full site. The reason is almost boring: less to build, not a different rate card. Charge a studio four figures for a full website and they'll usually land in the same range for one page done properly, just at the low end of it. On the numbers agencies actually report, full custom projects run from roughly $2,000 to $100,000, most under $10,000. A single page sits at the bottom of that band. So the real first question isn't what's cheap. It's whether the job needs one page or several.
So what does that bill actually cover on a single page? One round of copy. One layout. One build. No content management system behind it, no navigation to plan, no sitemap. The bigger swing in price is where the studio sits, not what they're building. Agencies in the US, Canada and Australia typically bill $100 to $149 an hour; teams in Eastern Europe, Latin America and parts of Asia bill $25 to $49 for comparable work. Two quotes for the same page, three or four times apart, and the page itself is rarely why.
Page count is not what pushes a landing page's price up. Custom copywriting does. A form wired into a real CRM, a payment processor or a booking system does. Animation and interaction work does. Tracking set up properly for paid traffic does. A single page carrying all four of those can cost more than a five-page brochure site with none of them. Scope decides the price far more than the page count on the invoice.
There is a real case for one page, and it's narrower than most people assume. A dedicated destination for a paid ad or an email send, built around a single offer. A placeholder before a full site launches, there mainly so Google has already found and indexed the brand. A cheap, fast way to test whether an idea has any demand before committing to a proper build. In each of those, the visitor has already been primed elsewhere. The page's whole job is one action, not a menu of them.
Here is the honest tension. One page cannot split traffic across more than one search intent, so it cannot be found for more than one thing at a time. It will not build the depth of content, or the inbound links, that come from a site people actually reference and quote. That caps organic growth on purpose, and that's fine for a campaign page with a fixed lifespan. It's a real cost if organic search is meant to carry the business over time, not just this quarter.
A single page gets outgrown fast: more than one offer, more than one audience, a real query worth ranking for beyond the one the page was built around, a plan to publish anything over time. At that point the landing page stops being the cheaper option and starts being the thing standing in the way. Better to say so early than let someone spend on a page that needs replacing within six months.
The question worth bringing to a studio, then, isn't how much for a landing page. It's whether a landing page is even the right size for what you're trying to do. That's a conversation, not a quote, and it takes five minutes to have before either one gets written.
