The calculator above opens on a patio with the stamped finish already picked, at an example rate of $16 per square foot against $9 for a standard broom finish. That spread is the whole story of stamped work: same slab, very different day between the screed and the cure.
Where the extra money goes
Stamped concrete costs more because everything happens inside a window. Color hardener gets broadcast and floated in. Release agent goes down. Mats get set, tamped, and pulled in sequence before the slab firms up, and a big pour needs extra hands and enough mats to stay ahead of the set. Pattern choice matters too: a random stone texture is forgiving, while a running-bond or ashlar pattern has lines that have to stay straight across the whole pour.
Then there is the work after the cure that broom finishes never see: cutting, washing off release, touching up color, sealing. For the full rate build-up, read how to price stamped concrete.
Sealing matters more on stamped
On plain flatwork, sealer is an upsell. On stamped work it protects the thing the customer paid the premium for: the color. The example add-on above runs $2 per square foot. Put it in the quote, and tell the customer it needs redoing every few years. Faded, chalky stamped concrete produces the angriest callbacks in flatwork, and a sealing line item on the original quote is what makes the future maintenance visit feel normal.
The math, side by side
A 12 by 16 patio is 192 square feet. At the example broom rate of $9, that is $1,728. Stamped at the example $16 is $3,072. That $1,344 gap is the conversation to have standing in the yard with the calculator open, because half of selling stamped work is showing the customer where the money goes.
If they flinch at the number, colored concrete at the example $12 rate splits the difference. If they are weighing pavers instead, stamped concrete vs pavers walks that trade-off, and stamped vs plain concrete covers the downgrade path honestly.
These are example numbers. Your stamped rate depends on your crew, your patterns, and your market. PriceDesk runs this same calculator with your rates on your phone, free for 14 days, no card required.
