Why these beat a plain calculator
Waste is built in
Order the exact calculated amount and you'll come up short the first time the ground isn't level. Every tool adds a waste factor you control, so the number you see is the number to order.
Cost, not just quantity
Type in your price per ton, bag, or sheet and get a running total. Change suppliers, change the number, see the new cost.
Made for the truck, not the desk
Big inputs, a numeric keypad on your phone, and the answer right where you need it. No scrolling past three ads to find the result.
Every number is one you can check
We don't hide the constants the math runs on. Each one matches a published industry reference, so a pro can sanity-check the result before ordering.
How far each material actually goes
Rough coverage for the units suppliers sell in, so you can sanity-check a number before running a full calculation. Confirm against your own supplier and local code before you order.
| Material | Sold by | One unit covers | Worth knowing |
|---|---|---|---|
| Crushed gravel & stone | the ton | ~100 sq ft at 2" deep | Sold by weight, so denser stone covers a little less. Halve it for a 4" base. |
| Ready-mix concrete | the cubic yard | 81 sq ft at 4" thick | Drops to 54 sq ft at 6" thick. One yard is 27 cubic feet. |
| Bagged concrete | the 80 lb bag | 0.6 cu ft per bag | 45 bags make a cubic yard, or 60 bags if you buy the 60 lb size. |
| Drywall | the 4×8 sheet | 32 sq ft per sheet | A 4×12 sheet covers 48 sq ft and leaves fewer seams to tape. |
| Asphalt shingles | the square | 100 sq ft per square | That's 3 bundles. Add about 10% waste, more on a cut-up roof with lots of valleys. |
| Topsoil & mulch | the cubic yard | ~100 sq ft at 3" deep | Bagged mulch runs about 2 cu ft, so roughly 14 bags equal a yard. |
These are planning estimates, rounded for quick math. For your exact job, with waste and cost built in, run the matching calculator.
Questions people ask
Every one, with no sign-up. They run in your browser, so there's nothing to install and nothing to pay.
That's what they're built for. Big inputs, a numeric keypad on the number fields, and the answer right under what you typed. No hunting past ads to find it.
They use standard material densities and the same units your supplier sells in, and they add the waste most calculators skip. Treat them as planning estimates and confirm against your supplier and local code before you order.
Because flat, square ground is a myth. Order the exact calculated amount and the first low spot leaves you short. You set the percentage; the default is the one most jobs need.
