Decorative & colored concrete cost calculator
Estimate the cost of integrally colored, stained or dyed concrete: base flatwork from your price per square foot, plus a dollar line for the color or stain.
Calculator
Colored/decorative concrete over 400 sq ft at $8.00/sq ft plus color is about $4,180.00.
“Decorative concrete” covers any finish that adds color or texture to an otherwise plain gray slab: integral color mixed into the batch, acid stain or water-based dye applied to a cured surface, and color hardeners broadcast onto fresh concrete. Unlike stamping, colored concrete keeps a smooth or broom finish, so the premium over plain flatwork is smaller — usually the cost of the pigment or stain and a bit of extra labor. This calculator splits the job into two honest parts: the base flatwork at your quoted rate, and a single dollar line for the color or stain package.
Keeping color separate makes it easy to compare bids and to see what the upgrade actually costs. A basic integral color across a patio might add a few hundred dollars; a multi-tone acid stain with a sealer coat can add much more. Enter the base rate and the color line from your quote, and the tool buffers the total with a contingency for the usual unknowns.
Formula
Base flatwork plus the color package, buffered by contingency:
total = (area_sqft × price_per_sqft + color_stain) × (1 + contingency)
- price_per_sqft — the plain-pour installed rate from your quote.
- color_stain — the total dollar cost of integral color, acid stain, dye or a color-hardener upgrade.
- contingency — a decimal buffer (0.10 = 10%).
Worked example
For 400 sq ft of patio poured at $8/sq ft, with a $600 integral-color upgrade and a 10% contingency:
base = 400 × $8 = $3,200
subtotal = $3,200 + $600 = $3,800
total = $3,800 × 1.10 = $4,180
That gives about $4,180 as a planning estimate. Swap the $600 integral color for a $1,400 two-tone acid-stain-and-seal package and the total rises to roughly $5,060, while the base pour stays the same — the split makes the trade-off obvious.
Integral color vs stain vs dye
Integral color is the most durable option because the pigment runs through the whole slab, so chips and wear are less visible; stains and dyes color only the surface and generally need resealing to hold up outdoors. If you plan to seal colored concrete, size the sealer with the sealer coverage calculator. For a textured decorative finish instead of a flat color, compare stamped concrete and exposed aggregate. This is a planning estimate, not a bid, a mix design or an installation guide.
Frequently asked questions
How much does colored concrete cost?
As a labeled planning band, integrally colored concrete often runs about $7–14 per square foot installed — roughly the plain-flatwork rate plus the pigment and a little extra labor. Acid staining and multi-tone finishes cost more. Enter your own base rate and color line for a real number.
What is the difference between integral color and stain?
Integral color is mixed into the concrete before it is poured, so the color goes all the way through. Stain and dye are applied to a cured surface and color only the top layer, which usually means periodic resealing to keep the look.
Should the color be a separate line in my quote?
Yes — asking a contractor to itemize the base pour and the color package makes bids comparable and shows exactly what the upgrade costs. This calculator mirrors that split.
Does colored concrete need sealing?
Surface stains and dyes almost always do, and even integral color benefits from a sealer outdoors to resist UV fade and moisture. Budget the sealer separately with the sealer coverage calculator.
