If you don't own a car, let's start by determining whether it's feasible to consider buying one within your budget. That's a big deal - look into car purchasing (used car, new car, car insurance costs and more). And find a car that gets reasonable gas mileage (number of miles driven per gallon of gas burned).
1. Calculate Your Gas Mileage (MPG) - Find Out How Much It Costs You to Drive One MileCalculate gas mileage (MPG) - use a handy online mileage calculator or do it yourself:
Jot down your MPG as sum #1.
2. Calculate Your Trip LengthFigure out how many total miles you'll be driving. Use this great little online trip distance calculator, AAA or a similar travel club or a map.
Jot down the total miles as sum #2.
3. Find Current Gas PricesPlan your trip using approximate gas costs. It's easy enough to locate a local gas station with cheap prices - use AAA for average national gas prices and try these links for more precise costs of a gallon of gas along your travel route:
Choose three gas prices, add together and divide by three. Jot down the result as sum #3.
4. Calculate Your Trip Cost
And that's how much you will spend on gas during your car trip.
Now that you've gone through that exercise, I'll let slip that you might be able to find your travel gas cost at FuelCostCalculator.com (provided you'll be driving one of the car models listed).
