Estimate garden mulch volume, whole bags and bag-versus-bulk material costs, with optional user-supplied density rather than gravel assumptions.
01 / PURPOSE-SPECIFIC INPUTS
02 / RESULT & SUPPORTING WORK
Settling, moisture, uneven beds, compaction and supplier package sizes affect actual needs. This is a garden-material quantity and cost comparison, not a landscaping specification.

Garden geometry and package volume drive this estimate. Bag counts and bulk volumes share a single allowance-adjusted quantity, while optional density is entered explicitly for mulch rather than assumed from a different material.
Compare whole bag purchases and bulk pricing across multiple beds without conflating package volume, waste allowance or material weight.

Area is rectangle length times width, triangle base times perpendicular height divided by two, or pi times circle radius squared. Sum zone areas, multiply by depth, then apply the entered volume allowance once.
Whole bags equal the ceiling of order volume divided by bag-package volume. Only a machine-roundoff guard is applied at an integer boundary. One cubic meter needs 20 bags of 50 L, while 1.01 m³ needs 21.
1 ft³ = 0.028316846592 m³ and 1 yd³ = 0.764554857984 m³. Length and depth also use the exact international foot and inch definitions, keeping bag and bulk units distinct.
Bag cost uses whole package count times the entered bag price. Bulk cost uses the allowance-adjusted quantity in the selected pricing volume unit. Prices are user assumptions; delivery, tax, labor and supplier minimums are not inferred.
No. Optional weight is calculated only from a positive user-supplied mulch bulk density in kg/m³. Mulch moisture and material can vary widely; no gravel-density preset is silently reused.
Settling, moisture, uneven depth, compaction and actual bag packaging or supplier measurements can alter requirements. This is a quantity and cost estimate, not a landscaping specification.
