EVRatio builds free EV calculators for drivers using primary-source data from the EIA, AAA, and EPA. Use the form below for questions about our tools, data corrections, or press inquiries. EVRatio provides cost estimates based on authentic data. We are not financial advisors — our calculators are estimation tools, not personalized financial guidance.

What we can help with

  • Calculator questions — inputs, outputs, or what a result means
  • Data corrections — if a state electricity rate, gas price, or vehicle spec looks wrong, include the primary source you are comparing against (EIA, EPA, AAA)
  • Methodology questions — how we apply SAE J1772 efficiency, how we source EIA state rates
  • Press inquiries — about EVRatio or US EV cost data

What we don’t offer

  • Financial advice — for significant money decisions, consult a qualified financial advisor
  • EV purchase recommendations — we calculate costs, we do not recommend specific vehicles
  • Warranty or repair support — contact your EV manufacturer directly
