1. What is the Drive or Fly Calculator?

The Drive or Fly Calculator helps you compare the total cost of driving versus flying for a trip, considering both direct costs (fuel or airfare) and the value of your time.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• Fuel Cost — Estimated cost of gasoline for the trip
• Airfare — Cost of plane tickets
• Time Value — Your personal valuation of time ($/hour)
• Travel Time — Total time spent traveling (hours)

Explanation: The calculator compares the sum of direct costs and time costs for both transportation methods.

3. Importance of Cost Comparison

Details: Many people only consider direct costs when choosing transportation, but time is often the most valuable resource. This calculator helps make more informed decisions by quantifying both factors.

4. Using the Calculator

Tips:

• For fuel cost, estimate based on your vehicle's MPG and current gas prices
• Include all airfare costs (bags, seat selection, etc.)
• For time value, consider your hourly wage or opportunity cost
• Include all travel time (driving to airport, security, layovers, etc.)

5. Frequently Asked Questions (FAQ)

Q1: How should I determine my time value?
A: Many people use their hourly wage. Others may value leisure time differently than work time.

Q2: Should I include hotel costs for overnight driving?
A: Yes, any additional costs associated with one method should be included in that method's total.

Q3: What about wear and tear on my vehicle?
A: The IRS mileage rate includes depreciation - you could use this as a more comprehensive driving cost.

Q4: How accurate are the results?
A: Results depend on accurate inputs. The calculator provides estimates, not guarantees.

Q5: What other factors should I consider?
A: Comfort, environmental impact, luggage needs, and personal preference may also influence your decision.
