Carpool Savings Calculator

How the Carpool Savings Calculator Works

The Carpool Savings Calculator helps determine how much money you can save by carpooling instead of driving alone. It calculates savings based on your daily driving distance, fuel efficiency, fuel costs, and the number of carpool passengers.

Calculation Formula

The savings formula used is:
\[ \text{Daily Savings} = \text{Solo Cost} - \text{Per Person Cost} \]
Where:

• Solo Cost is the fuel cost for driving alone.
• Per Person Cost is the shared fuel cost among all passengers.

Example Calculation

For a daily drive of 20 miles, a fuel efficiency of 25 MPG, a fuel cost of $4 per gallon, and 4 passengers:

• Solo Cost: \( \frac{20}{25} \times 4 = 3.2 \text{ dollars} \)
• Per Person Cost: \( \frac{3.2}{4} = 0.8 \text{ dollars} \)
• Daily Savings: \( 3.2 - 0.8 = 2.4 \text{ dollars} \)
