This calculator compares the true monthly cost of commuting in Cincinnati by car versus by Cincinnati Metro (SORTA). It shows driving cost two ways — bare cash for fuel and parking, and the full IRS cost of ownership — so you can see the honest trade-off against a transit pass.
How it works
The tool first converts your trips into monthly miles, then prices fuel and applies the IRS rate for full cost:
monthly_miles = round_trip_miles * commute_days
fuel_cost = (monthly_miles / mpg) * gas_price
drive_cash = fuel_cost + monthly_parking
drive_full = monthly_miles * 0.67 + monthly_parking
transit = metro_pass (~$72)
The cash figure is what leaves your wallet now; the full figure adds the depreciation and maintenance the IRS rate captures. The cheaper option is flagged in green.
Example
A 22-mile round trip, 22 days a month, is 484 miles. At 27 mpg and $3.20 gas
that is about $57 of fuel; with $100 parking the cash cost is $157/mo, while
the IRS full cost is about 484 x $0.67 + $100 = $424/mo. Against a $72
Metro pass, transit wins on both measures.
Notes
Pass prices, gas prices, and parking change often, so update the inputs for your situation. The IRS full-cost comparison is calibrated for an average gasoline car and is approximate for hybrids and EVs.
