HVAC Checks Energy Tool

Pump Energy Cost Estimator

Estimate pump energy use, annual cost, and rough VFD savings with a shared HVAC Checks tool shell that matches the rest of the published calculator pages.

Pump Energy Cost Estimator

Inputs

Flow Rate:

Total Head:

Pump Efficiency (%):

Motor Efficiency (%):

Operating Hours per Year:

Electricity Cost ($/kWh):

Optional: Speed Reduction with VFD (%):

Parameter	Value
Flow (GPM)	-
Head (ft)	-
Brake Horsepower (BHP)	-
Motor kW	-
Annual Energy Use (kWh)	-
Annual Energy Cost ($)	-
With VFD Savings ($)	-

BHP = (Flow × Head) / (3960 × Efficiency). Energy use is based on motor input kW × hours.

This tool is for preliminary estimating only. Actual pump selection and energy cost analysis should be verified with manufacturer data and site-specific conditions.
