How to Calculate Energy Consumption
Calculate electricity costs from wattage, hours, and rate.
The Formula
Cost = W × H × Rate / 1000The energy consumption formula uses the mathematical relationship: Cost = W × H × Rate / 1000. Each variable in the formula represents a measurable quantity that affects the final result.
Step-by-Step Method
- 1Identify all input values needed for the energy consumption calculation.
- 2Substitute your known values into the formula: Cost = W × H × Rate / 1000.
- 3Perform the arithmetic operations in the correct order (PEMDAS/BODMAS).
- 4Check that your result has the correct units and is within a reasonable range.
- 5Verify using the interactive Energy Consumption Calculator to confirm your answer.
