Concrete calculator
Concrete Patio Cost Calculator
Estimate patio concrete and a low, typical, and high installed budget using your own quoted rates.
Planning estimate, not a contractor quote. Review the assumptions and replace presets with local prices when available.
Method
How this calculator works
A basic patio, a decorative finish, and a replacement patio can have very different scopes. Start with installed rates from comparable local quotes and add only upgrades and removal that those rates exclude. The concrete order is a quantity cross-check, not an extra material charge added on top of an installed rate. Price inputs start at zero to avoid presenting a made-up local quote.
Concrete yd³ = length × width × thickness inches ÷ 324 × allowance factor. Each cost band = area × (installed band rate + removal rate + finish upgrade rate) + fixed charges.
Worked example
A realistic starting point
A 200 ft² project at illustrative installed rates of $8, $12, and $16 per ft² starts at $1,600, $2,400, and $3,200. Adding $2/ft² removal, $1/ft² finish upgrades, and $200 fixed charges produces $2,400, $3,200, and $4,000. These are arithmetic examples, not market prices.
What changes the answer
Factors worth checking
Match the quoted scope
Check excavation, base, reinforcement, forms, placement, finishing, and curing with the contractor. Add only genuinely excluded items.
Quantity and price are separate
Thickness changes concrete volume. It only changes the installed cost when you enter a rate that reflects the thicker specification.
Fixed charges
Small-job minimums or difficult access can behave as fixed charges. Keep these visible rather than hiding them inside a universal square-foot price.
Common questions
Concrete Patio Cost FAQ
Why does the initial price show zero?
No quote has been entered. Enter local rates and extras to obtain a meaningful budget.
Does the total include concrete delivery?
Only when it is already inside the installed rates or included in fixed charges. Do not add it twice.
Can I compare finishes?
Use the comparison scenario with finish-specific rates and extras, keeping the base scope consistent.
