- 1.3 yd³
- Fill cost
- Enter bag price
The quantity is fixed by geometry: 8×4 ft × 12 in deep plus a labeled 10% settling buffer = 24 bags, or 1.3 yd³ in bulk. Only the price is missing — put your store's bag price in and the total computes live.

Why
We don't guess store prices — soil and lumber vary several-fold by region, so every dollar here is your price × a computed quantity.
- Quantities are computed (same sourced volume model as our Soil calculator); prices are yours — that's the only honest way to do garden cost math, because soil and lumber prices vary several-fold by region.
When this doesn't apply
- Excludes tools, irrigation hardware, tax and delivery — add them as a lump in the fertilizer/amendments line if you want them counted.
- In-ground gardens: set frame price to 0 and depth to the few inches of compost you'll work in, not 12.
How this was calculated
