What actually decides what a patio costs

Square footage is the obvious variable and rarely the one that swings a quote the most. The bigger factors are usually underground: what the slope is doing, what the soil does with water, and what has to come out before anything new goes in.

A flat, well-drained lot with nothing to remove is the cheapest yard to build on, and it is also the least common one in most of the neighborhoods we work in. A sloped lot needs either a retaining wall or a lot more base material to make a level patio; a lot that already holds water after rain needs drainage work before the patio, not instead of it.

Material is the other half of it. Paver, natural stone and poured concrete are three different price points before a single hour of labor is counted, and within paver alone, pattern and thickness move the number too.

What we do on every estimate: walk the yard, point at the specific things driving the price up or down, and show the math rather than a flat number pulled from a phone call. If two things about your yard are keeping the price higher than a neighbor's similar-looking patio, you should know what they are and why.
