Rideshare Cost Compare Calculator — Formula
## Rideshare vs Driving Cost Comparison
Comparing rideshare fares to the true cost of driving (including fuel, depreciation, insurance, and parking) reveals when each option makes financial sense.
### Formula
**Rideshare = Base Fare + Per Mile Rate x Distance**
**Own Car = Cost per Mile x Distance x 2 (round trip) + Parking**
The IRS mileage rate ($0.67/mile in 2024) captures total car ownership costs. For short trips with expensive parking, rideshare often wins.

Exemplo Resolvido
An 8-mile trip, rideshare at $3 base + $1.50/mile, own car at $0.67/mile + $10 parking.
- Rideshare = $3 + $1.50 x 8 = $15.00
- Own car = $0.67 x 8 x 2 + $10 = $10.72 + $10 = $20.72
- Rideshare saves $5.72 on this trip
