One fault of my employer is that I get charged for parking. $647, once per year. This gives me convenient parking, in a deck right next to my building.
There’s an alternate plan, wherein I can pay $25 per year, and pay $5 each time I park a vehicle. It’s not as convenient, but is pretty close to my work.
So the pay-per-park plan has a break-even point at 126 days: if I park 126 days, it saves me money, and it I park 127 days, it costs me money. Last year, I had 227 complete work days. Using 2011 as a baseline, I would have to bike 101 days in the next year to not lose money on this scheme. Any more days than that, and I’m putting money back in my pocket. I would need to bike 44% of the time, 2.2 days per week.
Maximum possible savings: $632 (yay!). Maximum possible loss: $503 (boo!).
| % of the time I bike to work | Amount of money I save |
| 100% | $632 saved |
| 75% | $347 saved |
| 50% | $67 saved |
| 25% | $218 lost |
| 0% | $503 lost |
