How much is a Valley Metro pass in Mesa?

A Valley Metro 31-day full-fare pass runs about $64, covering bus and light rail across Mesa and the wider Phoenix metro. Reduced-fare passes for eligible riders cost less.

What is the difference between cash cost and IRS full cost?

Cash cost counts only fuel plus parking — what leaves your wallet now. IRS full cost uses the standard mileage rate (about $0.67/mile) to also capture depreciation, maintenance, insurance, and tires, the true long-run cost of driving.

Why include parking in the comparison?

Parking is a real recurring driving expense. In Mesa a monthly space averages around $60, though many suburban workplaces offer free parking, in which case you can set the field to zero.

Does transit always win?

Not always. For short commutes with free parking and a fuel-efficient car, driving cash cost can beat a $64 pass. The tool shows both the cash and full-cost comparisons so you can decide.

Are gas prices fixed in the tool?

No. The gas price field is editable so you can enter the current Arizona pump price. Default values reflect typical Mesa-area conditions but should be updated for accuracy.

This calculator compares the monthly cost of driving in Mesa, Arizona against taking transit. Driving is priced two ways — a cash basis (fuel plus parking) and a full-cost basis using the IRS standard mileage rate — and stacked against a Valley Metro 31-day pass of about $64.

How it works

Monthly miles drive the fuel and full-cost figures; transit is a flat pass:

monthly miles = round_trip * commute_days
fuel cost     = (monthly miles / mpg) * gas_price
drive cash    = fuel cost + monthly parking
drive full    = monthly miles * IRS_rate + monthly parking
transit       = valley_metro_pass (~$64)

The IRS standard mileage rate (about $0.67/mile) bakes in depreciation, maintenance, and insurance, so full cost is always higher than cash cost.

Example

A 20-mile round trip, 22 days a month, at 28 mpg and $3.30/gas with $60 parking: monthly miles 440, fuel (440/28)*3.30 = $51.86, cash driving 51.86 + 60 = $111.86. Against a $64 pass, transit saves about $47.86/month on a cash basis.

Notes

These are estimates. Update gas price, parking, and fuel economy for your own vehicle and route. If your workplace offers free parking, set the parking field to zero. The IRS rate is a long-run average, not a monthly cash outlay.
