Ice Melt Calculator
Enter your driveway and walkway area, the product you use, how many storms you realistically fight each winter, and the bag price. The calculator gives pounds per application, bags for the season, and the cost.
More salt does not melt faster - the right dose works once and the surplus wrecks concrete and paws. This calculator prices the product honestly by type: rock salt quits near 5 F, blends reach -10, calcium chloride keeps working to -25, and the pet-safe blends cost more for reasons the paws will explain.
How to use
- Measure the paved area you actually clear, including the walkway.
- Pick the product for your coldest realistic storm, not the record.
- Buy at season start; the first storm empties the aisle.
Frequently asked questions
How much ice melt do I need per 1000 square feet?
About 4 pounds of rock salt, 6 of a blended melt, or 3 of calcium chloride per application. Spreading double does not double the speed - it doubles the runoff, the concrete damage and the cost.
Which ice melt is safe for pets and concrete?
Pet-safe blends use gentler salts and cost more per bag; on paws, any product should be wiped off after walks. On concrete under one year old, avoid rock salt entirely - use calcium-based products sparingly, or sand for traction.
At what temperature does rock salt stop working?
Around 5 F (-15 C). Blends reach roughly -10 F and calcium chloride keeps melting near -25 F. Below a product limit, adding more does nothing - that is what the calculator's temperature column is for.
Should I salt before or after snow?
Before, if you can - a pre-treat layer stops the bond forming and turns the shovel job into a sweep. After, it still works but slower. The calculator sizes the per-storm dose either way.
