HP・効率・稼働時間・電気料金でポンプの電気代を計算します。日・月・年コスト。
Enter your pump horsepower, motor efficiency (typically 80–90%), daily runtime hours, and your electricity rate per kWh. The calculator converts HP to kilowatts accounting for motor losses.
The formula: Power (kW) = (HP × 746) ÷ (efficiency% ÷ 100) ÷ 1000. Daily cost = kW × runtime hours × rate. This gives you accurate daily, monthly, and annual operating costs.
Use this calculator to compare the cost of running your current pump versus a more efficient variable speed model. Even a modest reduction in HP or efficiency improvement can save hundreds per year.
