Topsoil Buying Guide
This guide helps you turn your topsoil calculator result into a cleaner purchase plan. Use it when you want fewer return trips, better waste assumptions, and a more realistic cart.
Step 1: Decide on the soil grade
Unscreened topsoil is cheap but full of rocks and roots, fine for filling deep holes. For planting beds or lawns, always pay extra for screened topsoil.
Step 2: Account for settling
Freshly poured topsoil is very fluffy. It will settle by about 20% after the first few rains, so order a little extra to ensure your final grade is correct.
Step 3: Consider a compost blend
Pure topsoil lacks nutrients. If you are starting a garden, order a 50/50 blend of screened topsoil and rich compost to give your plants the best start.

Don't just buy dirt. You may also need soil amendments, fertilizer, a heavy-duty wheelbarrow, and a grading rake to level it out.
Understanding the Math
Formula: The basic formula for Topsoil Calculator typically involves calculating the total area or volume (Length × Width × Depth) and dividing by the coverage of a single unit or package, then adding a waste factor (usually 10%).
Example: For example, if you have a 10x10 area and your material covers 10 square feet per unit, you need 10 units. With a 10% waste factor, you should purchase 11 units to ensure you don't run short.
