Match material and units
Determine the required volume first, then compare quotes for material suitable for the same use. Topsoil, compost and potting mix are not interchangeable solely because their prices differ. One cubic yard equals 27 cubic feet. Convert both offers before comparing unit costs.
Example for bagged soil
For a target of 32 cubic feet, sixteen 2 cubic foot bags at $8 each cost $128. If delivery adds $20, the total is $148 before any additional applicable tax. These are hypothetical prices for an arithmetic example, not current national retail prices.
Example with a bulk minimum
Suppose bulk material costs $80 per cubic yard, delivery is $60 and the supplier sells only whole yards. A 32 cubic foot target exceeds one yard, so the order is two yards: $160 in material plus $60 delivery, or $220 before additional tax. Do not price just 32 ÷ 27 yards if the supplier will not sell that fraction.
Check what happens with fractional orders
A supplier allowing exact fractional orders would change the same calculation: 32 ÷ 27 × $80 + $60 is approximately $154.81 before tax. Verify minimum volume, order increments and delivery charges rather than assuming either bulk rule. Include access limitations and where the delivery can be unloaded.
Calculate bags here and bulk separately
Our bag calculator gives whole bags, purchased volume, leftover and entered bag cost. It does not automatically add delivery or model bulk minimums. Record its result and add external charges. For bulk, multiply the actual purchasable yards by the quote, then add fees; compare both totals and the usefulness of any leftover.
Frequently asked questions
Is bulk always cheaper?
No. Minimum quantities and delivery can reverse the comparison.
Does the bag calculator include tax and delivery?
Only amounts already included in the price you enter; it does not add separate charges.
