Calculating Fill Dirt for a Pool Removal: You Need 1 Cubic Yard, Not 6.5

The Math

15 ft diameter circle = 176.7 sq ft. 6 inches deep = 88.35 cu ft = 3.27 cu yd. Wait—your 6.5 cu yd was for 12-inch depth. For 6 inches, order 3.5 cu yd to allow for settling.

Cheapest Source

• On-site: dig post holes, new beds, French drain—use that soil.
• Bulk fill dirt: $10–$15/cu yd delivered (10–15 yd minimum).
• Bagged topsoil: $4–$5/bag (2 cu ft) = $54–$68/cu yd—only for tiny amounts.

Tip

Compact in 6-inch lifts. Top with 4 inches screened topsoil for grass.
