Method
How this estimate works
- The site uses current district-level regular gas prices from the latest published pipeline output.
- ZIP lookup uses the GeoCorr 2022 ZIP-to-CD119 crosswalk. Split ZIPs require you to choose the correct district.
- Cost estimates are based on
miles/day ÷ MPG × district gas price. - ZIPs missing from the ZCTA crosswalk do not receive an inferred match. Use the manual district selector instead.
