Number of Calculators: 8
- Gas Mileage (MPG)Calculate your vehicle's fuel economy in MPG or liters per 100 km from the distance traveled and fuel used.
- Fuel CostCalculate how much fuel a trip will cost from the distance, your vehicle's fuel economy, and the price of fuel.
- Auto LeaseEstimate your monthly car lease payment from the vehicle price, down payment, residual value, term, and APR.
- Tire SizeCompare two tire sizes to see the difference in overall diameter and how it affects your speedometer accuracy.
- HorsepowerEstimate a vehicle's horsepower from its quarter-mile trap speed or elapsed time and weight.
- Life Insurance NeedsEstimate how much life insurance coverage you need using the DIME method (Debt, Income, Mortgage, Education).
- Cash Back vs. Low InterestCompare a dealer cash rebate at the standard rate against a low promotional rate at full price to see which actually costs less.
- Car DepreciationEstimate a vehicle's resale value after a number of years using a commonly-cited real-world depreciation curve.
Guided Journeys
Some of these calculators are also part of a guided journey — a connected chain that carries your numbers forward automatically. A journey may include steps from other categories too.
Fuel Economy Journey
Start Journey →Your vehicle's real-world fuel economy is the missing number behind almost every trip-cost estimate. This journey starts by calculating your actual MPG from a fill-up, then carries that figure into the fuel cost calculator so you get a trip or commute cost based on your car's real efficiency instead of a guess.

Car Buying Journey
Start Journey →Buying a car involves more than just the sticker price: you need a realistic monthly payment, a clear answer on whether a cash rebate or a low promotional rate actually saves you more, and a sense of what the vehicle will cost to fuel once it's yours. This journey starts with the loan payment, carries the same vehicle price into the rebate-vs-low-rate comparison so you don't have to look it up twice, then walks through the vehicle's real-world fuel economy and what a typical trip or commute will cost in gas.
