FixerCalc

Gravel Calculator

Gravel quotes mix yards and tons. This tool shows both from the same depth, and lets you set density so a “ton” matches your rock, not a generic internet number.

Results update as you type. Units stay imperial inside the math.

Area

Paths often 2–4 in; drive bases are thicker and belong in the driveway calculator.

Weight

If you fill this in, material cost uses tons × this price instead of yards.

  • Wet stone, large cobble, and pea gravel do not weigh the same. Edit tons per cubic yard to match your quarry.
  • This is material volume only. Base fabric, edging, and compaction loss are extra.

How this calculation works

  1. Volume is the same rectangle-or-area × depth math as mulch.
  2. Tons = cubic yards × tons per yard. Crushed limestone is often near 1.2–1.5 t/yd³ depending on gradation and moisture.
  3. Cost uses $/yard unless you enter a $/ton, which is how many quarries actually sell.

yd³ = sq ft × (in/12) / 27 × (1+waste%); tons = yd³ × tonsPerYard

What to do next

  • Ask the yard for compacted vs. loose density if the stone will be driven on.
  • For a driveway section, use the driveway calculator so thickness and surface type stay consistent.
  • Order a little extra; shorting a gravel delivery means a second trip charge.

FAQ

Should I order by the ton or the yard?
Order the way the supplier prices it. Convert with their density, not a forum average, if the ticket unit differs from how you measured the hole.
Does compaction mean I need more yards?
Yes. Crushed stone knits together. An 8% extra is a planning start, not a soils lab result. Deep bases need a contractor’s takeoff.

  • Volume = area × depth; yards = ft³ / 27
  • Default 1.35 tons/yd³ is a mid planning density for crushed stone; supplier tickets override this
