Concrete Patio Cost Calculator
Building a backyard patio? Enter your dimensions and finish preference to see how much concrete you need and what the project will cost. Covers both basic and decorative options.
Choosing the Right Finish
A basic broom finish costs the least and provides good traction. Sweep a stiff broom across wet concrete to create grooves that prevent slipping. This works great for utility areas or if you plan to cover the patio with rugs or furniture.
Stamped concrete mimics the look of stone, brick, or tile. Contractors press patterns into the surface before it fully cures, then apply color hardeners or stains. The effect looks high-end but costs 50% to 100% more than a plain finish.
Exposed aggregate reveals the small stones in the concrete mix. After pouring, the top layer of cement paste is washed away, leaving a textured, natural look. It resists wear, hides stains, and stays cooler underfoot in summer than smooth concrete.
Sizing Your Patio
Think about how you'll use the space. A dining table for six needs at least 10 by 12 feet. Add a grill, seating area, or fire pit and you're looking at 16 by 20 feet or more. Sketch your layout on graph paper before digging.
Consider the proportions. Long, narrow patios feel cramped. Aim for a shape that balances width and depth. If your yard is small, an irregular shape that follows garden beds or natural contours can maximize usable space without overwhelming the yard.
Don't forget clearances. Leave 3 to 4 feet of walkway around furniture and grills. Plan drainage so water flows away from your house. A slight slope of 1/4 inch per foot prevents puddles without making the patio feel tilted.
Cost-Saving Strategies
Doing your own excavation and base prep cuts labor costs significantly. Rent a plate compactor to pack the gravel base tight. A well-compacted base prevents settling and cracking, which saves repair costs later.
Pour in sections if you're on a budget. Build half the patio this year and extend it next year. Use control joints to tie the sections together without visible seams. This spreads the expense and lets you test the layout before committing to the full size.
Skip the decorative finish on areas that will be covered by furniture or planters. Apply stamping or staining only where it shows. Mixing finishes within one patio adds visual interest and trims the bill without sacrificing curb appeal.
Frequently Asked Questions
How thick should a concrete patio be?
Four inches is standard for patios. Since patios don't bear vehicle weight, 4 inches provides plenty of strength for foot traffic and outdoor furniture.
What is the average cost per square foot for a concrete patio?
Basic patios cost $6 to $10 per square foot. Stamped, stained, or exposed aggregate finishes run $10 to $15 or more per square foot.
Do I need a permit for a concrete patio?
Many areas allow small patios without a permit, but rules vary. Check with your local building department before starting, especially for large or elevated patios.
How do I prepare the ground for a patio?
Excavate to depth, add 4 inches of compacted gravel, install forms, and ensure proper slope for drainage (1/4 inch per foot away from structures).
Can I pour a patio myself?
Yes, if the area is small and you have help. Concrete sets fast, so plan your pour carefully. For patios over 200 square feet, hiring a contractor often makes sense.
