How City vs Highway Fuel Cost Calculator Works?
This tool works by subtracting the highway fuel cost of a distance from the city fuel cost of the same distance. The result is the extra cost of city driving.
Price the city drive
Calculate cost at city miles per gallon (MPG). The default is 500 miles at 22 MPG and $3.60 per gallon: $81.82.
Price the highway drive
Calculate cost at highway MPG. The default is 500 miles at 34 MPG and $3.60 per gallon: $52.94.
Enter both costs
Type the city cost in field 1 and the highway cost in field 2.
Read the city penalty
The tool returns the extra dollars spent in city driving.
City vs Highway Fuel Cost Calculator Formula
The formula is City Penalty = City Fuel Cost − Highway Fuel Cost.
City Penalty = |City Fuel Cost − Highway Fuel Cost|Formula variables
- City Fuel Cost
- (Miles ÷ City MPG) × Price.
- Highway Fuel Cost
- (Miles ÷ Highway MPG) × Price.
Worked example
- City Cost (22 MPG, 500mi): $81.82
- Highway Cost (34 MPG, 500mi): $52.94
- City: (500 ÷ 22) × $3.60 = $81.82.
- Highway: (500 ÷ 34) × $3.60 = $52.94.
- City penalty: $81.82 − $52.94 = $28.88.
Result: $28.88 ($ city penalty)
City driving costs 54.5% more than highway driving in this example. Hybrids shrink the gap, since hybrid city ratings often match or beat highway ratings.
City vs Highway Fuel Cost Calculator Conversion Table
The table shows the city penalty for 3 city costs against 3 highway costs.
Rows: City Cost (22 MPG, 500mi) ($). Columns: Highway Cost (34 MPG, 500mi) ($). Cells: $ city penalty.
| $ | $40.00 | $52.94 | $65.00 |
|---|---|---|---|
| $60.00 | $20.00 | $7.06 | $5.00 |
| $81.82 | $41.82 | $28.88 | $16.82 |
| $100.00 | $60.00 | $47.06 | $35.00 |
A $100 city cost against a $40 highway cost gives a $60.00 penalty for the same distance.
What is City vs Highway Fuel Cost Calculator?
The City vs Highway Fuel Cost Calculator is a tool that measures the extra fuel cost of city driving compared with highway driving. The tool shows how road type changes the fuel bill.
City driving burns more fuel through idling, braking, and accelerating from stops. Gasoline cars often rate 20% to 35% lower in the city than on the highway.
The comparison helps drivers choose routes and vehicles for their usual road mix.
What are the uses of City vs Highway Fuel Cost Calculator?
