Paver Patio Calculators
Pavers, bedding sand and compacted base for a patio, with the base depth driving both the tonnage and the excavation.
There are 2 calculators here: Paver Patio Calculator (pavers, base stone, bedding sand and cost for a patio) and 16x20 Paver Patio Material & Cost Calculator (pavers, base and sand for a 16 by 20 foot patio).
They all work the same way: quantity first, then a waste allowance you can change, then a price built from verified figures and adjusted for your state. Cost is always a range rather than a single number, and every assumption behind it is printed on the page with its source and the date it was last checked.
