The Charlotte Commute Cost Calculator compares what it actually costs to get to work in Charlotte by car versus by CATS transit. It uses your real commute distance, local gas prices, fuel economy, monthly parking (averaging around $100), and optionally the IRS per-mile rate so you can see the full cost of driving — not just gas — against the roughly $88/month transit pass. It is for commuters weighing the LYNX light rail or a bus pass against driving, and for anyone budgeting the often-hidden cost of getting to the office.
How it works
Driving cost has two or three parts, depending on whether you include wear-and-tear:
round-trip miles/month = one-way miles x 2 x commuting days
fuel cost = (round-trip miles / MPG) x gas price
driving (fuel only) = fuel cost + monthly parking
driving (IRS full cost) = round-trip miles x IRS rate + monthly parking
Transit cost is simply the monthly pass price. The tool reports both driving views — fuel-only and IRS-full-cost — next to the transit figure, then names the cheaper option and the monthly and annual savings. The IRS view matters because it folds in maintenance, insurance, and depreciation, which fuel alone ignores.
Example and notes
A 12-mile one-way commute, 21 days/month, 28 MPG, gas at $3.20, parking $100, transit pass $88:
round trip: 12 x 2 x 21 = 504 miles/month
fuel: 504 / 28 x 3.20 = $57.60
driving (fuel only): $57.60 + $100 = $157.60/month
driving (IRS @ $0.67): 504 x 0.67 + 100 = $437.68/month
transit: $88/month -> cheaper
- Hybrid workers should count only the days they actually travel — fewer days makes transit relatively less attractive but slashes driving fuel and parking.
- If your route has tolls, fold them into the parking field as a monthly amount.
