Costs & Operations
Operating tools using the rates you enter (no stored tariffs): fill cost and fill time, pump energy cost, turnover flow, filter sizing and water-loss (evaporation vs leak).
Fill CostEstimate what it costs to fill your pool from the gallons and your own water rate — priced per gallon, per 1,000 gallons or per CCF. No tariff stored.Fill TimeFind out how many hours it takes to fill your pool from a garden hose or supply line, using the gallons and the flow rate in gallons per minute (GPM).Pump Energy CostEstimate the daily, monthly and yearly electricity cost of running your pool pump from its horsepower, motor efficiency, run hours and your own $/kWh rate.Turnover / FlowFind the pump flow in GPM needed to turn over your whole pool within a target number of hours — the basis for sizing pumps, filters and daily run time.Filter SizeFind the minimum filter area for your flow rate using standard design rates for sand, cartridge and D.E. media — size the filter to match your pump flow.Water LossTurn a measured drop in water level into gallons lost and inches per day, and see whether it looks like normal evaporation or a possible leak.
Every Costs & Operations tool is calculated server-side — visible immediately — with its formula, a worked example and a reference table. Background reading is in the guides.
