Editorial Policy
How we create, review, and update EV charging cost calculators and guides, including sources, assumptions, and corrections.
Our editorial promise
EV Charging Cost Pro is built to answer one question well: what does charging an EV actually cost in real life, and how can you lower it. Our tools and guides are designed to be practical, transparent, and easy to verify.
How we create and update content
- Calculator-first approach: every guide is connected to a decision the calculator helps with (home charging, TOU rates, fast charging, cost per mile, break-even).
- Explain assumptions: we state default values (charging losses, efficiency, rates) and let users change them where it matters.
- Source the “defaults”: when we reference common ranges or public data, we link to primary sources (for example, EIA/DOE/EPA pages).
- Human review: we review for clarity, math correctness, and “does this help a driver make a better choice.”
Accuracy and limitations
Charging costs vary by electricity plan, charging losses, weather, driving style, and station pricing. We provide estimates that are useful for planning, not a substitute for your utility bill or a station receipt. When your results differ from real-world costs, the most common causes are:
- Time-of-use pricing and demand charges at public stations
- Charging losses (heat, battery conditioning, cable/charger efficiency)
- Different vehicle efficiency (Wh/mi) than your assumed value
Independence and monetization
We may display ads to support hosting and maintenance. Ads do not influence calculator formulas or our recommendations. We do not accept paid placement for charging networks or utilities inside the tool.
Feedback and corrections
If you spot an error or want a new feature, use the contact page. If we confirm a correction, we document it on the changelog.
