EV Range Estimator

What it does

Real-world EV range vs rated range. Accounts for cold weather, highway speeds, HVAC use. Money math compounds: small percentage differences over years become large dollar differences.

The financial-planning context here is straightforward: the math is simple but the variables are personal: tax bracket, time horizon, and risk tolerance change every answer. A 7% return looks great until you adjust for inflation and taxes.

Practical pitfalls to avoid: for high-stakes decisions (homes, retirement, business loans), cross-check against a CPA or fee-only fiduciary financial planner who can layer your specific tax and estate context. A common pitfall: promotional teaser rates that reset to higher numbers later.
