Reproducible scenario data
Commuter Fuel Cost Scenario Benchmark
This reproducible table computes annual and monthly fuel cost for a hypothetical 50-mile daily round trip across 260 workdays, crossing fuel economies of 30, 35, and 40 MPG with gas prices of 3.00, 3.50, and 4.00 dollars per gallon. Maintenance, depreciation, tolls, and parking are excluded.

How do fuel economy and gas price change the annual fuel cost of a hypothetical 50-mile daily round-trip commute?
This reproducible table computes annual and monthly fuel cost for a hypothetical 50-mile daily round trip across 260 workdays, crossing fuel economies of 30, 35, and 40 MPG with gas prices of 3.00, 3.50, and 4.00 dollars per gallon. Maintenance, depreciation, tolls, and parking are excluded.
What assumptions does this benchmark use?
Every row is generated from the displayed inputs and formulas. Values are deliberately hypothetical so the table remains reproducible and does not misrepresent a local rate, platform policy, compensation level, or professional recommendation.

How should you use these numbers?
Use the table to understand sensitivity, then replace every assumption with current values relevant to your decision. The linked calculator provides editable inputs. Do not treat a hypothetical row as a quote, policy, tariff, compensation survey, or purchase instruction.
