How to use the Mulch Calculator

Estimate mulch volume in cubic yards and the number of bags required for a landscape bed.

Calculation formula

Mulch cubic feet = bed length × bed width × depth/12; cubic yards = cubic feet/27; bags = ceil(cubic feet/bag size).

Recommended steps

1. Enter values using the units shown beside each field.
2. Review whether the example assumptions match your situation.
3. Run the calculator and compare the key metrics.
4. Use the source data or official rates when precision matters.

Known limitations

Volume before compaction and settling; order extra material for irregular beds or slopes.
