Ice Melt Calculator
Calculate how much ice melt or rock salt you need for your driveway, sidewalk, or parking lot.
Ice Melt Needed
Ice melt coverage depends on the product type and ice thickness.
General guidelines:
| Product | Coverage per lb | Best Temp |
|---|---|---|
| Rock Salt (NaCl) | 60–80 sq ft (5.6–7.4 m²) | Above 15°F (-9°C) |
| Calcium Chloride | 80–100 sq ft (7.4–9.3 m²) | Down to -25°F (-32°C) |
| Magnesium Chloride | 70–90 sq ft (6.5–8.4 m²) | Down to 0°F (-18°C) |
Application rates:
- Light ice: 2–4 oz per sq yard (70–140 g per m²)
- Heavy ice: 4–8 oz per sq yard (140–280 g per m²)
- Both metric (m²) and imperial (sq ft) are supported
Tips:
- Apply before ice forms for best results
- More is not better — excess damages concrete and plants
