Why use DriveWise?
A car is the second-biggest purchase most people make, and the running costs add up quietly: fuel, charging, interest and tires. A one-inch-larger wheel can throw off your speedometer, a longer loan can add thousands in interest, and a road trip can cost twice what you expected. DriveWise turns those questions into clear numbers, and shows every step so you can check the math yourself.
Where to start
- Buying new wheels or tires? The tire size calculator shows whether a new size fits within the usual 3% of the original diameter, and how far off your speedometer will read.
- Planning a road trip? The fuel cost calculator gives the total and the cost per person.
- Thinking about an electric car? The EV charging cost calculator compares charging with filling up a gas car over the same distance.
- Financing a car? The car loan calculator includes the trade-in, sales tax and dealer fees that a basic loan calculator leaves out.
- Wondering what your car really gets? The MPG calculator works out true fuel economy from a single fill-up.
Three habits that save drivers money
- Check tire pressure monthly. Under-inflated tires wear faster and burn more fuel.
- Get pre-approved before you shop. A loan offer from your bank or credit union gives you a rate to compare against the dealer's.
- Measure, don't guess. The fuel economy on the dashboard is often a little optimistic; a fill-up calculation tells you the truth.
