Soil and Mulch Bag Calculator
Estimate how many bags of soil or mulch may be needed from area, depth, bag size, and waste allowance.
This calculator helps with small garden and landscaping planning. It uses volume math only. Soil settling, uneven ground, compaction, edging, slopes, and product differences can change the real number.

Before buying
Check the product label carefully. Bags may be sold by litres, cubic feet, weight, or coverage area. Weight is not the same as volume because moisture and density vary.
