Mulch Calculator

Estimate landscape bed area for rectangular or circular shapes, choose a mulch depth, calculate volume in cubic feet and cubic yards, work out how many bags you need and compare bulk versus bagged mulch cost.

Bed Area Depth & Volume Bags & Bulk Project Cost

All-in-One Landscaping Mulch, Volume And Cost Suite

Switch between area, depth and volume calculators, bag count, cost estimation and quick unit conversions to plan mulch for garden beds, borders, trees and full-yard projects.

Calculate mulch bed area for rectangular spaces, circular tree rings or a combination of both. You can fill either or both shapes.

Leave blank if you only need a circle.
Radius from center to edge of circular bed or tree ring.
Applies to rectangle and circle inputs.

Use area and mulch depth to estimate volume in cubic feet, cubic yards and cubic meters. Works with imperial or metric depths.

Common depths: 2–3 in for beds, 3–4 in for weed control.

Convert mulch volume into bag count using a bag size in cubic feet. Many retail bags are 2 or 3 cubic feet.

Common bag sizes: 1.5, 2 or 3 ft³ per bag.

Compare bulk mulch cost per cubic yard with bagged mulch cost per bag for the same required volume.

Typical local landscape supply price per yd³.

Convert common mulch-related units: area, depth and volume between imperial and metric systems.

Mulch Calculator uses Rectangle Length, Rectangle Width, Circle Radius, Length Unit, Area Value.

Mulch Calculator Formula or Method

  • Most mulch projects start with a simple question: how big is the area you want to cover? The area tab lets you enter a rectangular section, a circular bed or a combination of both. Rectangular beds are calculated as length times width. Circular beds are calculated using the radius and the standard formula π × radius².
