How it works
Finding a cheaper gas station doesn't automatically mean you save money — you have to subtract the fuel cost of driving there and back. This tool deducts the round-trip fuel cost from your price-difference savings to show the real net gain.
FAQ
Q. How do I enter the one-way distance?
A. Just enter the distance to the cheaper station one-way — the calculator automatically doubles it for the round trip.
Q. Does this factor in the value of my time?
A. No, it only compares fuel cost. If your time is valuable, factor that in separately.
