Cole's EV Calculator
EV charge, range & trip costs
Free · Designed for iPad. Not verified for macOS.
Know how long an EV charge takes, what it costs and how many miles it adds. Then see how much an electric car saves on a trip compared with gas.
Work out an EV charge in seconds. Enter your battery size, your charger and your electricity price, drag the charge range, and see how long it takes, what it costs and how far it adds.
CHARGE
• Charge time for any start and end percentage
• Cost of the charge, from your electricity rate
• Miles (or km) added, plus your range on a full battery
• "Ready by" time, so you know when to unplug
• Quick-pick chips for common home and fast-charger speeds, and your own custom speeds
• Optional charging slowdown near full, and optional charging losses
• Car limits (maximum AC and DC charge rate) for a more realistic time
• Tap the result to see exactly how it was worked out, in plain words
TRIP COMPARE
• Compare the cost of a trip in a gas car and an electric car
• See how much the electric car saves per trip and per mile
• Enter fuel price, mpg, electricity price and efficiency
• Works in US, UK or metric units
MADE FOR EVERYDAY USE
• Save your numbers in named sets, like "Home" or "Road trip" (optional)
• Ask Siri or use Shortcuts: "How long to charge in EVCalc", "How much to charge in EVCalc", and "How far can I go in EVCalc"
• Seven color themes, light and dark mode, Dynamic Type and VoiceOver support
• Designed for iPhone, iPad and Mac with Liquid Glass
PRIVATE BY DESIGN
Cole's EV Calculator collects no data. There is no account, no tracking and no ads. Anything you save stays on your device.
A NOTE ON ACCURACY
Results are estimates. Real charging speed depends on your car, the charger, temperature and battery condition, and the slowdown curves in the app are approximations, not measurements.

What's new in 1.1
• Time-of-use electricity pricing
- Does your utility charge less at night? Turn on Time-of-use pricing in Settings and set up a price schedule for the day. Charge now works out your cost hour by hour, based on when you plug in. Pick a start time, or tap Now. You can use the same schedule on Trip Compare, with the average, cheapest or highest price.
• Trip stops
- Trip Compare now tells you whether each car makes the trip in one go. Add your gas tank size and you'll see how many fill-ups and charging stops each car needs, and how far a tank goes.
• CO₂ saved
- Trip Compare shows how much CO₂ you avoid by not burning gas, in pounds or kilograms.
