About Watt The Frunk

WattTheFrunk: The EV Calculator That Actually Does the Math WattTheFrunk is a premium comparison engine for Gas, EV, and Plug-in Hybrid (PHEV) vehicles, built for drivers who want realistic numbers, not marketing fluff. While most vehicle calculators rely on outdated assumptions and ignore international metrics, WattTheFrunk gives you the power to calculate your true driveway costs and exact breakeven point based on your real-world driving habits. Why it’s different: Built for PHEVs: We don't ignore plug-in hybrids. Our unique logic accurately models "blended" driving to show you exactly how far $10 takes you on battery versus gas. Globally Smart: Whether you use MPG, L/100km, or kWh/100km, the tool automatically adapts to your local currency and units. Real-World Variables: Don't just rely on home electricity rates. Adjust your specific mix of home, public L2, and DC fast charging to see your true running costs. Data Backed: Pull direct specs from the EPA vehicle database, or manually override any input with custom dealership data. Zero-Friction Sharing: Generate ultra-short, instant links to send your exact customized scenario to a friend, spouse, or car dealer. Stop guessing your savings. Run the numbers at WattTheFrunk.
