MPG Calculator - Miles Per Gallon

MPG Calculator - Calculate Miles Per Gallon

Calculate your vehicle's fuel efficiency instantly with our free MPG calculator. Simply enter miles driven and gallons used to get accurate miles per gallon (MPG) measurements.

How to Calculate MPG

Calculating your vehicle's fuel efficiency is simple:

1. Fill up your tank completely
2. Reset your odometer to zero
3. Drive normally until you need to refuel
4. Fill up again and note the gallons needed
5. Calculate MPG using our calculator

MPG Formula

MPG = Miles Driven / Gallons Used

For example, if you drove 300 miles and used 10 gallons of gas:

MPG = 300 / 10 = 30 MPG

Understanding Fuel Efficiency

What is MPG?

MPG (Miles Per Gallon) measures how far your vehicle can travel on one gallon of fuel. Higher MPG means better fuel efficiency and lower fuel costs.

Typical MPG Ratings:

Vehicle Type	City MPG	Highway MPG	Combined
Small Car	25-35	35-45	28-38
Midsize Car	20-30	30-40	23-33
SUV	15-25	20-30	17-25
Truck	15-20	20-25	16-22
Hybrid	45-55	50-60	48-55
Electric	100+ MPGe	100+ MPGe	100+ MPGe

Tips to Improve Your MPG

Driving Habits:

• Drive at steady speeds (55-65 mph is optimal)
• Avoid rapid acceleration and hard braking
• Use cruise control on highways
• Combine trips when possible
• Reduce idling time

Vehicle Maintenance:

• Keep tires properly inflated
• Use recommended motor oil
• Replace air filters regularly
• Keep engine tuned
• Remove excess weight from trunk

Expected Improvements:

• Proper tire pressure: +3% MPG
• Smoother driving: +10-15% MPG
• Regular maintenance: +4% MPG
• Reduced weight: +1-2% MPG per 100 lbs

MPG vs. Other Measurements

Conversions:

• Liters per 100km: Common in Europe and Canada (lower is better)
• km per Liter: Used in some countries (higher is better)
• MPGe: Miles Per Gallon equivalent for electric vehicles

Quick Conversion:

• 30 MPG = 7.84 L/100km
• 25 MPG = 9.41 L/100km
• 20 MPG = 11.76 L/100km

Why Track Your MPG?

Benefits of Monitoring Fuel Efficiency:

• Save Money: Identify when your vehicle needs maintenance
• Detect Problems: Declining MPG may indicate issues
• Compare Vehicles: Make informed decisions when car shopping
• Better Planning: Estimate fuel costs for trips
• Environmental Impact: Track your carbon footprint
