Energy Cost Calculator

Energy Cost Calculator – Track Usage, Demand Charges & Save Money

Easily calculate the energy consumption and operating cost of your electrical devices, appliances, or industrial machines — now with Power Factor analysis and multi-device comparison.

Just enter:
• Power Consumption per Hour (kW)
• Daily Usage Time (Hours)
• Electricity Rate (Cost per kWh)

Get instant results for:
• Energy Consumption: Daily, Monthly, and Yearly
• Cost Analysis: Daily, Monthly, and Yearly
• Demand Charges: Peak Load (kW) with Power Factor (pf) correction — optional
• Carbon Emissions: Estimate your environmental impact across Coal, Oil, Natural Gas, and Nuclear sources

What's new in this version:

Power Factor Analysis
Enter your peak demand and power factor (pf) to calculate Apparent Power (kVA). Know whether your utility bills on kW or kVA, see the billing basis, and understand the true cost of low power factor — critical for commercial and industrial users.

Multi-Device Comparison
Add multiple appliances or machines and compare their monthly and yearly costs side by side. A live stacked bar chart shows which devices consume the most — so you know exactly where to cut.

Share Your Results
Export a full PDF report of your calculations — including demand charges, power factor analysis, and CO2 emissions — with a single tap.

Ideal for:
• Homeowners reducing electricity bills
• Businesses and facility managers tracking equipment costs
• Electrical engineers and energy auditors conducting power audits
• Industrial users managing demand charges and power factor penalties
• Anyone seeking to optimise power usage and reduce energy spend

Whether you're planning an energy audit, sizing an electrical installation, or simply monitoring your household usage, this tool gives you actionable insights in seconds.
