How it works
Estimate whole bags for a uniform mulch layer. Bag volume and depth are converted to the same volume unit.
Inputs and units
| Input | Example value | What to enter |
|---|---|---|
| Area | 20 m² | Required unit: m². Must be greater than zero. |
| Layer depth | 5 cm | Required unit: cm. Must be greater than zero. |
| Bag volume | 50 L | Required unit: L. Must be greater than zero. |

Reading the result
Convert measurements to the same unit and use the net area to cover. Replace any package, waste or efficiency input with your product information. A quantity estimate alone does not determine installation conditions.
Questions and answers
Can I use the example values for my own calculation?
The example values illustrate the calculation. Replace every input with your own information, especially dates, rates and the selected operation.
Why are some results rounded?
Results display up to 8 decimal places. Calculations use the unrounded values; very small values use scientific notation. JavaScript floating-point arithmetic can introduce tiny rounding differences.
Are my inputs sent to a server?
The calculator processes inputs in your browser. Its code does not send your values to a server.
