Methodology & Notes
Formula: Area (sq ft) x Depth (in) / 12 = cubic feet. Divided by 27 = cubic yards. Multiplied by 0.7646 = cubic metres. 30L bags = cubic metres x 1000 / 30. Plan 5-10% extra for settling.

“Always order 10% more soil than you calculate — it compacts once watered. In Montreal, I've seen clients run short after their first heavy rain and have to pay a second delivery fee that costs more than the extra soil would have.”
How to use this tool
Enter the dimensions of your raised bed, garden area, or fill zone. Choose between rectangular and circular shapes. The calculator outputs the volume needed in cubic yards, cubic metres, and standard bag equivalents. For raised beds, measure the internal dimensions and the depth of soil needed. For fill projects, measure the area and the depth you need to raise the grade.
Why it matters
Ordering the right amount of soil saves money and prevents waste. Buying too little means extra delivery charges for a second load, while ordering too much leaves you with an unwanted pile. In Montreal, bulk soil delivery starts around $60 per cubic yard for topsoil, with triple-mix averaging $75 to $95 per cubic yard delivered. For raised vegetable gardens, a blend of topsoil, compost, and peat moss creates the ideal growing medium for Quebec's short but productive growing season.
Frequently Asked Questions
How much does a cubic yard of topsoil cost in Montreal?
In Montreal, topsoil costs $60 to $80 per cubic yard delivered in 2026. Triple-mix (topsoil + compost + peat moss) runs $75 to $95 per cubic yard. Delivery fees typically range from $50 to $100 depending on distance and minimum order.
How much soil do I need for a raised garden bed?
A standard 4×8 foot raised bed that is 12 inches deep requires about 1.2 cubic yards of soil mix. For vegetable gardening in Montreal, use a mix of 60% topsoil, 30% compost, and 10% peat moss for the best growing results in Quebec's short season.
What is the best soil mix for gardens in Quebec?
