What Gravel Driveway is for

Gravel Driveway Calculator is the page to open when you need gravel driveway from measurements you already have. It belongs with the other construction calculators because that is the work this arithmetic supports. The pour, when the surface is concrete, is the concrete volume. Type the entries first. The result stays hidden until you press Calculate, so a half-finished form never flashes a number you might mistake for the answer.

How to fill in this calculator

The formula in plain language

Loose material is ordered by the cubic yard. Multiply length, width, and depth in feet, then divide by 27. Weight in tons is that yardage times the material's density. Dry sand is near 1.3 tons per yard, compacted gravel near 1.4 to 1.5, and mulch closer to 0.4.

A worked example

A 12 foot by 40 foot driveway with 4 inches of gravel is 160 cubic feet, or 5.93 yards. At 1.4 tons per yard that is about 8.3 tons. At $45 a ton the stone is about $370 before delivery.

A driveway is an area, a thickness, and a material. This gravel driveway number should match asphalt calculator and cost of a driveway.

Mistakes that move the answer

Depth is the compacted depth you want, not the fluffy depth in the truck.
A ton and a cubic yard are not the same amount. Ask the supplier which one the price uses.

How to check the result

After Calculate shows the gravel driveway result, redo the last operation with a pencil using the rounded figures on the screen. Matching that check means the inputs were read correctly. If you edit a label or a sentence in this HTML file, reload the page. The form and this article both live in the file, so the edit is what visitors will read.
