Pad estimating note
Small pads are simple to measure, but final cost can change fast when you include base prep, reinforcement, forms, delivery fees, access, finishing, and whether the pad supports equipment or heavy loads.
Common small pad thickness
4 inches
Hot tubs, generators, and heavy equipment may need more.
Calculate concrete pad cost
Enter pad dimensions, thickness, base depth, forms, reinforcement, labor, finishing, delivery, and waste to estimate total concrete pad cost.
Pad estimate
Estimated total
$1,465
About $15 per square foot.
This is a planning estimate. Final pad pricing depends on demolition, excavation, soil, drainage, access, reinforcement, forms, finish quality, equipment load, local labor, material pricing, and code requirements.
For homeowners
Estimate small concrete pads for sheds, AC units, generators, grills, trash bins, utility areas, and backyard upgrades.
For contractors
Quickly estimate pad yards, form length, base material, reinforcement, labor, delivery, finishing, and total pricing assumptions.
For property managers
Use the calculator to plan concrete pads for equipment, utilities, storage, maintenance areas, and property upgrades.
Concrete pad calculator FAQs
How thick should a concrete pad be?
Many small residential pads are 4 inches thick. Heavy equipment, hot tubs, generators, vehicle loads, poor soil, or local requirements may need thicker concrete.
How do I calculate concrete for a pad?
Multiply length by width by thickness in feet to get cubic feet. Divide by 27 to convert to cubic yards, then add waste or overage.
Does a concrete pad need gravel base?
A compacted gravel base is commonly used to improve support and drainage. Base depth depends on soil, climate, drainage, and load requirements.
Can I use bags instead of ready-mix?
Small pads may be possible with bagged concrete, but larger pads usually become easier with ready-mix delivery. Use the Concrete Bag Calculator to compare bag count.
