How to use the Garden Soil Calculator

Estimate soil for raised beds, garden beds, planters and landscaping using the area and target fill depth.

Step by step

What to enter

  2. Enter the depth of soil you need to add.
  3. Choose bagged or bulk purchase mode and enter the package size.
  4. Add an allowance and optional price.
Method

How the calculation works

PlanCalq multiplies the footprint area by soil depth to calculate fill volume, then applies your allowance for settlement and grading.

The final volume is converted into the package or bulk unit you expect to purchase.

Calculation summaryLength × width × depth = soil volumeVolume × (1 + allowance %) = recommended volumeRecommended volume ÷ package volume = purchase quantity
Common questions

Garden Soil Calculator FAQs

Can I use this for a raised garden bed?

Yes. Enter the internal length, width and fill depth of the bed for a straightforward volume estimate.

Should I add extra soil for settling?

A small allowance is useful when freshly placed soil is expected to settle after watering or light compaction.

Does the calculator estimate soil weight?

The main purpose is volume and purchase quantity. Soil weight varies significantly with composition and moisture.
