Cal Gas

A simple gas calculator to quickly compare prices of 2 gas stations.

Imagine yourself at 2 gas stations, ARCO and Exxon, side by side. On the boards, ARCO appears to have cheaper gas, but consider this: ARCO does not accept credit cards, so you either pay cash or debit card; if you pay with debit card, there is a 0.35 cents "debit card fee". Exxon, on the other hand, allows you to pay with credit card, which lets you earn up to 5% cashback depending on your credit card company. Potentially, with the extra fees and your credit card cashback, you might get a better deal at Exxon. But it is not always obvious and often tedious to calculate.

Cal Gas provides just the solution to all your calculation woes. This app will save you TIME and MONEY. Don’t believe me? Here’s a simple example for you.

ARCO board price: 2.19/gallon.

Exxon board price: 2.32/gallon.

Let’s say your car has a gas tank of 15 gallons. If you pump ARCO with debit card, the total cost would be $2.19x15 + 0.35 = $33.20. If you pump Exxon with a credit card that gives you 5% cashback on gas, your total cost would be $2.32x15x0.95 = $33.06. It turns out, Exxon is surprisingly cheaper!
