What we love hearing about

  • Mistakes. If a calculator gives a wrong answer or a guide has an error, please tell us. We'll fix it and add a note crediting the report.
  • New tool ideas. Calculators we haven't built yet that would have helped you. Concrete use cases are especially useful (“I wanted to figure out X but had to do the math by hand”).
  • Guide topics. Questions you Googled and didn't find a clear answer for — that's exactly what our long-form guides are for.
  • Updates on industry data. If you spot that we have stale tax credit rules, outdated EV specs, or wrong charging network info, please correct us.

What we can't help with

  • Individual financial, tax, or legal advice. Our calculators are for general planning. For specific decisions consult an accountant or a financial advisor.
  • Vehicle purchase recommendations. We help you do the math; we don't pick the car for you.
  • Charging or electrical work on your specific car or home. Always use a licensed electrician.
  • Manufacturer warranty claims. We're independent — not affiliated with any maker. For warranty issues, talk to your dealer or the manufacturer directly.

Response time

Most legitimate messages get a response within 3–5 business days. We can't promise to reply individually to every note, but we do read all of them — especially correction reports.
