- EV charging time calculatorEnter your battery capacity, starting and target state of charge, and charger output to estimate charging time, the kWh pulled from the wall, and your cost per session — all from open, transparent formulas.
- EV road trip calculatorEstimate stops, charging time, and drive time from route distance, EV range, battery capacity, departure SOC, reserve SOC, target stop SOC and DC charger power.
- EV lease vs buy calculatorCompare a financed EV purchase against a lease over a 5-year horizon. Inputs: vehicle price, buy down payment, loan APR and term, 5-year residual value, lease payment, drive-off, and annual operating cost.
- EV total cost of ownership calculatorSum purchase price (minus federal tax credit), fuel/electricity, insurance, maintenance and registration over 5 years. Default electricity 4.0 mi/kWh, gas 28 mpg.

Electric Vehicle Calculators
Plan your EV ownership with free calculators for charging time, road-trip range, lease-vs-buy decisions, and total cost of ownership. Built on EPA range data, manufacturer charge curves, loan math, residual value assumptions, and current US electricity rates, these tools help you compare charging choices, estimate cross-country drive times, and project five-year ownership costs.
Formula notes
Formulas used in this calculator group
Compare the core equations behind each calculator in this hub before opening a detailed tool.
EV charging time calculator
- E_b = C_b × ΔSOC / 100
- E_w = E_b / η
- t = E_w / P
EV road trip calculator
- R_1 = R_v × ΔSOC / 100
- N = ⌈(D − R_0) / R_1⌉
- t_1 = E_1 / P_e
EV lease vs buy calculator
- C_b = D_b + P_60 + O_60 − V_60
- C_l = D_l + M × 60 + O_60
EV total cost of ownership calculator
- C_5 = C_0 + C_e + C_i + C_m + C_r
FAQ
Common questions for this calculator group
Review the most common planning questions from the calculators in this hub, with links back to each detailed page.
Which calculator in this group should I open first?
Start with the calculator whose title matches the decision you are making. The hub formulas help you compare what each tool actually models before you open the detailed page.
Why are the formulas shown as compact equations?
The hub view is a quick map. Each detailed calculator still explains the assumptions, inputs, examples, and caveats behind the equation.
Can I use these results before requesting a quote or buying equipment?
Yes, use them for early planning and comparison. Before purchase or installation, confirm the assumptions with equipment manuals, installers, utility rules, and local codes.
