About Dump the Pump
A free tool that compares the real running cost of a gas car against an electric one — using your driving, your car's efficiency, and your local gas and electricity prices.
What this is
Dump the Pump answers one question as honestly as we can: would going electric actually save you money? Pick the car you drive now and an EV you're considering, set your annual miles and your state's prices, and you get annual fuel cost for each, cost per mile, multi-year savings, and the break-even on an EV's higher sticker price. We show the math so you can check it.
Who makes it
Dump the Pump is an independent project — we're not a car maker, dealer, or any manufacturer's marketing site, and nobody pays us to favour a particular vehicle. It's one of a small set of plain-English home-energy tools we build, alongside WattDollar (what appliances cost to run) and SolarDime (whether solar is worth it). Questions, corrections, or feedback are genuinely welcome at ownership@dumpthepump.net.
How it works
The calculator runs entirely in your browser. Nothing you type — your car, your prices, your miles — is sent to us or anyone else; it stays on your device. We pre-fill typical efficiency figures for dozens of popular EVs and your state's average gas and electricity prices so you don't have to look them up, and you can change any of it to match your exact situation. The numbers are typical estimates for guidance, not a quote — your real-world results and local prices will differ, so use your own figures for any decision.
How we keep it free
The tool is free and has no signup. We cover costs two ways, both disclosed plainly: we show ads (via Google AdSense), and some outbound links — like "shop this EV," insurance, financing, or a home charger — are affiliate links that may earn us a commission at no extra cost to you. These relationships never change the calculator's math or the figures it uses. See our Disclosure for the details and our Privacy Policy for how ads and links handle data.
