Pool Salt Calculator

Estimate how many bags of salt needed for your saltwater pool. Calculate based on pool volume, current salt level, and target PPM.

📏 Pool Volume Method

📏 Length (feet)

📐 Width (feet)

📏 Shallow End Depth (feet)

📐 Deep End Depth (feet)

🧂 Current Salt Level (PPM)

Test your pool water with salt test strips

🎯 Target Salt Level (PPM)

📦 Salt Bag Size (lbs per bag)

🧂 Salt Required

0 bags

0 lbs of salt

Add salt gradually and run pump for 24 hours before retesting.

🧂 Pool salt calculation formula: (Target PPM – Current PPM) × Pool Volume (gallons) ÷ 1,000,000 × 8.34 = lbs of salt needed. Each 40 lb bag raises salt ~500 PPM per 10,000 gallons.

💡 Pro tip: Use 99.8% pure pool-grade salt (not table salt). Add salt in shallow end with pump running, brush until dissolved. Wait 24 hours before turning on chlorinator.
