Road Trip Shared Cost Calculator

How to calculate shared trip costs?

To split costs, you must first determine the total fuel expense based on distance and efficiency, then add fixed costs like lodging.

Formula: ((Distance / MPG) × Fuel Price + Tolls + Lodging + Food) / Travelers

Using the Road Trip calculator: an example

Example: 4 travelers on a 1000-mile trip with a 25 MPG car, gas at $3.50, and $400 in other costs.

Step-by-step calculation:

• Calculate fuel: (1000 / 25) × 3.50 = $140
• Add other costs: $140 + $400 = $540
• Divide by group: $540 / 4 = $135 per person

Frequently Asked Questions

Should the driver pay less?

Some groups reduce the driver's share to compensate for vehicle wear and tear (depreciation) and maintenance costs.

How do we handle individual food costs?

If food costs vary significantly, it is often fairer to track meals individually and use this calculator only for shared expenses like fuel and lodging.
