Sprinkler System Calculator
Calculate the water usage and cost for your sprinkler system. Understand how flow rates, area size, and water pressure affect your irrigation expenses.
Step 1: System Details
Understanding Flow Rates
Flow rate determines how much water each sprinkler head uses per minute. Typical residential sprinklers use 1-3 GPM. Higher flow rates cover larger areas but increase water usage.
Step 2: Water & Cost Details
About Water Rates
Water rates vary significantly by location. Typical residential water costs range from $0.002 to $0.015 per gallon. Check your water bill for accurate local rates.

Water Cost Analysis
Water Cost Formula
Cost = (Sprinklers × Flow Rate × Time × Days × Rate) × 4.33
The monthly cost is calculated by multiplying the number of sprinklers by their flow rate, watering time, days per week, and water rate, then multiplying by 4.33 (average weeks per month).
