Estimate stone for gabions from the inside dimensions and count of identical rectangular baskets. Use placed bulk density, which includes gaps between rocks, to calculate US short tons and estimated stone-only cost.

Stone quantity and price estimate only, not a retaining-wall design or supplier quote. Use placed bulk density including gaps, not solid-rock density. Excludes baskets, delivery, tax, labor, base, filters and backfill. A US short ton is 2,000 lb. Dengaro is a financing broker, a brand of Funding Routes LLC, not a lender; stone costs are not a financing amount.
How it works
Multiply each basket's inside length, width and height in feet, then multiply by the number of identical baskets. Divide cubic feet by 27 for cubic yards. The mass calculation uses placed bulk density in pounds per cubic foot, including the air gaps between stones. Do not apply an additional void reduction to a density that already includes those gaps. The default of 100 lb per cubic foot is an illustrative assumption, about 1.60 metric tonnes per cubic meter, not a promise about your supplier's stone. Confirm the density for your material and placement method before ordering.
Formula
Total cubic feet = inside length × inside width × inside height × basket count. Cubic yards = cubic feet ÷ 27. Placed US short tons = cubic feet × bulk density in lb per cubic foot ÷ 2,000. Order tons = placed tons × (1 + extra allowance percent ÷ 100). Estimated stone-only cost = order tons × your estimated price per ton. Allowance adds stone; it does not enlarge the baskets.
Example
Each basket holds 54 cubic feet. Ten hold 540 cubic feet, or 20 cubic yards. At an illustrative placed density of 100 lb per cubic foot, the fill weighs 54,000 lb, or 27 US short tons. A 5% extra-stone allowance makes the order estimate 28.35 short tons. At an assumed $60 per short ton, the estimated stone-only cost is $1,701.
Tips
Ask the basket manufacturer for the approved rock gradation, mesh opening, bracing and filling method. Undersized rock may escape through the mesh. Price filter fabric, base material, backfill, lacing, baskets, labor, delivery and tax separately. For different basket sizes, calculate each size group and sum its volume and tonnage; do not round a volume ratio into a basket layout.
Scope
This estimate does not size retaining walls, foundations or drainage and does not check sliding, overturning, bearing pressure or slope stability. Have a qualified designer assess retaining applications and local requirements. All prices are estimates.

Important questions
No separate deduction is needed because the entered placed bulk density already includes voids. Solid-rock density is a different quantity and will overstate the mass if used directly. Ask your supplier for a placed bulk density appropriate to the basket filling method, not the density of a solid mineral specimen.
Every ton result and price input on this page uses a US short ton of 2,000 lb. Metric tonnes are 1,000 kg and are not interchangeable. Convert a supplier's density and price to the units shown before entering them; basket dimensions are in feet, not meters or inches.
It is an additive planning allowance for breakage, handling and extra stone recommended by the supplier. A 5% allowance multiplies the estimated placed mass by 1.05. Confirm whether the supplier's quoted density already includes an ordering allowance so you do not add it twice. This is not a compaction or void-space correction.
No. It estimates stone for a known count of identical rectangular baskets only. It excludes structural design, basket layout, baskets, excavation, foundation, drainage, fabric, labor, delivery and tax. A wall's safe geometry depends on site conditions and engineering, not just the amount of stone in its cages.
