   Enter the total weight of what you’ll be towing — including trailers, boats, or cargo. Example: 2500 lbs.
3. Add the Trip Distance (miles)
   Specify how far you plan to travel while towing. Example: 200 miles.
4. Include the Fuel Price ($/gallon)
   Input the current cost of fuel in your area. Example: $3.75 per gallon.
5. Click “Calculate”
   Once you hit the Calculate button, a short progress bar will appear while the tool estimates your results.
6. View Your Results
   After a few seconds, the calculator will display:
   • Adjusted MPG while towing
   • Total fuel used
   • Estimated fuel cost
   • Efficiency loss percentage
7. Copy or Share Your Results
   You can copy the results to your clipboard or share them directly via social media using the provided buttons.

Practical Example: Planning a Family Camping Trip

Let’s say you drive a Toyota Highlander that gets 25 MPG normally. You’re towing a 2,500-pound camper for a 200-mile trip, and the fuel price is $3.75 per gallon.

After entering these details into the Towing Gas Mileage Calculator, the results might look like this:

• Adjusted MPG: 18.75 MPG
• Gallons Used: 10.67 gallons
• Fuel Cost: $40.01
• Efficiency Loss: 25%

This means towing your camper reduces your fuel efficiency by 25%, costing you about $40 in fuel for the trip.

By using these insights, you can plan refueling stops, adjust your budget, or even decide if towing a lighter trailer would be more economical.
