Gas Gap is free to use and is supported by affiliate partnerships. Some of the links on this site, in particular those in the "Close the gap" section, are affiliate links. If you click one and sign up for or buy something, Gas Gap may earn a commission. It costs you nothing extra.
We only link to services that could plausibly reduce what a driver spends, such as fuel cashback apps and insurance comparison tools. A partner paying us a commission does not change the calculator's numbers, which come from AAA price data and EPA mileage ratings and are computed the same way for everyone.
The savings figures shown next to partner links are estimates based on the mileage and fuel prices you entered and on typical published rates (for example a per-gallon cashback rate or an average insurance saving). Your actual results will vary and may be zero.
Gas Gap is an information tool, not financial, insurance or legal advice. Read any partner's terms before signing up.
