What the site does

Each calculator is built to give a quick estimate based on wattage, runtime, and electricity rate. The goal is to make energy cost questions easier to answer without forcing users into complicated spreadsheets or utility jargon.

Whether you are comparing cooling options, checking the cost of an appliance, or planning home energy use, the site is designed to turn simple inputs into useful cost estimates.

Why it exists

The purpose of CostToRun.app is to help users understand energy usage in practical terms. Instead of only seeing watts or kilowatt-hours, visitors can estimate what those numbers may mean for everyday operating cost.

That makes it easier to compare devices, spot expensive habits, and make more informed household decisions.
