Quick answer
What does the Raised bed soil calculate?
How much soil fills the raised beds after settling allowance? This calculator uses number of beds, length per bed, width per bed, fill depth, and settling allowance to estimate soil for raised beds immediately in your browser.
With the values currently entered, the result is 4.43 yd³ — soil to order. It also shows per bed, and before settling allowance.
How to use the Raised bed soil
- Replace the example values with your own numbers.
- Review the result and supporting figures as they update automatically.
- Check the formula and assumptions before using the estimate for a decision.
Inputs used
- Number of beds — entered in beds
- Length per bed — entered in m
- Width per bed — entered in m
- Fill depth — entered in cm
- Settling allowance — entered in %
Raised bed soil formula
Beds × length × width × depth × settling allowance
Assumptions
- Beds are rectangular and filled uniformly.
- Existing soil or filler layers are excluded.
Practical guide
Raised bed soil example and edge cases
How much soil fills the raised beds after settling allowance? Let's use a concrete example, then look at the assumptions that can move the answer.
Example: A practical raised bed soil scenario
For this example, use number of beds of 3 beds, length per bed of 2.4 m, width per bed of 1.2 m, fill depth of 35 cm, and settling allowance of 12 %. These are starting values, so replace them with numbers that match your situation.
- Number of beds
- 3 beds
- Length per bed
- 2.4 m
- Width per bed
- 1.2 m
- Fill depth
- 35 cm
- Settling allowance
- 12 %
Calculated result4.43 yd³soil to order
Start with soil to order. Then check per bed, and before settling allowance to understand what sits behind the main result.
Example results use the default display profile. The calculator above follows your selected country and units.
How to read the result
- Read the main result first. The supporting figures for per bed, and before settling allowance explain how the estimate is built.
- The method is Beds × length × width × depth × settling allowance. Keep the units consistent and use values from the same time period.
Edge cases worth checking
When number of beds is unusual
Beds are rectangular and filled uniformly. Double-check this input before relying on the result.
When settling allowance is uncertain
Existing soil or filler layers are excluded. Run a lower and higher value to see a useful range.
What changes the result most
Number of beds
Change number of beds on its own first. This shows how strongly it affects the answer.
Length per bed
Measure length per bed with the same unit shown beside the input. Convert first if your source uses another unit.
Width per bed
Measure width per bed with the same unit shown beside the input. Convert first if your source uses another unit.

Common mistakes
Check number of beds
Beds are rectangular and filled uniformly. Make sure this matches the number you enter.
Keep settling allowance consistent
Existing soil or filler layers are excluded. Use the same units and time period throughout the calculation.
Do not rely on one raised bed soil scenario
Run a cautious case and an optimistic case. The range is often more useful than one exact-looking number.
