About MyElectricCalc

MyElectricCalc is a free online electrical load calculator built specifically for US homeowners, electricians, solar installers, and DIY planners. Our tool helps you calculate your home's total electrical load accurately — no electrician needed for basic planning.

Why We Built This Tool

Most homeowners have no idea how much electrical load their home actually draws. When adding a new appliance, upgrading to an EV charger, planning a solar system, or sizing a generator — the first question is always: "Does my panel have enough capacity?"

We built MyElectricCalc to answer that question instantly and for free. Our calculator follows US National Electrical Code (NEC) standards — the same standards licensed electricians use — to give you accurate load estimates you can actually trust.

What Our Calculator Does

• Calculates total home electrical load in watts and kilowatts
• Recommends correct circuit breaker size for 120V and 240V systems
• Estimates daily and monthly energy consumption in kWh
• Helps size generators, solar panels, and battery backup systems
• Follows NEC Article 220 demand factor standards
• Works on all devices — desktop, tablet, and mobile

Who Is This For?

🏠 Homeowners — Check if your 100A or 200A panel can handle a new EV charger, hot tub, or home addition before calling an electrician.

⚡ Electricians — Quick on-site residential load estimates before performing full NEC Article 220 calculations.

☀️ Solar Installers — Accurately size solar inverters and battery backup systems based on real home load data.

🔌 DIY Planners — Know your electrical requirements before starting a basement finish, garage conversion, or home addition.

Our Commitment to Accuracy

All calculations on MyElectricCalc are based on US NEC standards and typical US residential electrical values (120V/240V systems, AWG wire sizing, standard breaker ratings). While our tool provides accurate estimates for planning purposes, we always recommend consulting a licensed electrician for final load calculations and any electrical work.
