What Your Result Means
- Snow Volume: The total cubic feet of snow covering your area, calculated from the surface area and snow depth. This helps gauge the physical amount of material you need to move.
- Total Weight: How heavy the snow is, based on density. Light fluffy snow weighs about 7 lbs per cubic foot, while wet heavy snow can reach 15–20 lbs per cubic foot. This matters for roof load calculations and physical effort planning.
- Estimated Time to Shovel: A rough time estimate based on 30 minutes per 100 square feet of area. Actual time varies significantly with snow type, your fitness level, and equipment used.
- Salt/Ice Melt Needed: Pounds of rock salt or ice melt product for post-shoveling treatment. The rate increases with snow depth: 100 lbs per 1,000 sq ft for light dustings, up to 200 lbs for deep accumulations.
How This Calculator Works
You enter the area in square feet, snow depth in inches, and snow type (light, wet, or packed). The tool converts depth to feet, multiplies by area for volume, then multiplies by the snow density to get total weight. Shoveling time is estimated at 30 minutes per 100 square feet regardless of depth. Salt requirements use a tiered rate based on depth: 100 lbs per 1,000 sq ft for shallow snow, scaling up to 200 lbs for depths over 4 inches.
Quick Questions
How much does snow actually weigh?
Snow weight varies dramatically by type. Fresh powder weighs about 5–7 lbs per cubic foot, typical wet snow about 12–18 lbs, and packed or icy snow can reach 20–25 lbs per cubic foot. A single inch of wet snow on a 20×60-ft driveway can weigh over 1,000 pounds.
Is rock salt safe for all surfaces?
No. Standard rock salt (sodium chloride) can damage concrete less than one year old, harm vegetation, and corrode metal. Calcium chloride is gentler on concrete and works at lower temperatures but costs more. Avoid all deicers on brick pavers and natural stone unless the manufacturer approves it.
When is snow too heavy for my roof?
Most residential roofs are designed to handle 20–40 lbs per square foot of snow load. A foot of wet snow can approach 15–20 lbs per square foot. If accumulation exceeds 2 feet of wet snow or 4 feet of light snow, consider hiring a professional for roof snow removal.
How can I shovel snow faster?
Push snow rather than lifting when possible, clear snow before it gets packed down by foot traffic, work in passes across the width rather than the length, and apply salt or ice melt before the storm to prevent bonding. A snow blower dramatically reduces time for areas over 500 square feet.
