Find out exactly how much you spend on gas every month — and every year. Enter your daily miles, MPG, and gas price for an instant personalized estimate.
Open Full Budget CalculatorYour monthly gas cost depends on three things: how much you drive, how efficient your car is, and what gas costs in your area. The formula:
Most people are surprised by how much they spend on gas annually. That $150/month becomes $1,800/year — money that could go toward a car payment, insurance, or savings.
Based on 1,200 miles/month (average US driver) at $3.50/gallon:
| Vehicle Type | Avg MPG | Gallons/Month | Monthly Cost | Annual Cost |
|---|---|---|---|---|
| Hybrid Car | 45 MPG | 26.7 gal | $93 | $1,120 |
| Compact Car | 32 MPG | 37.5 gal | $131 | $1,575 |
| Mid-Size Sedan | 28 MPG | 42.9 gal | $150 | $1,800 |
| Crossover SUV | 26 MPG | 46.2 gal | $162 | $1,938 |
| Full-Size SUV | 20 MPG | 60.0 gal | $210 | $2,520 |
| Pickup Truck | 18 MPG | 66.7 gal | $233 | $2,800 |
| Full-Size Truck | 15 MPG | 80.0 gal | $280 | $3,360 |
Based on 1,200 miles/month and $3.50/gallon. Your actual cost depends on local prices and driving habits.
Most people significantly underestimate how much they spend on gas. Use Gaslo's monthly calculator to get your baseline, then check it against your actual bank or credit card statements. Knowing the real number motivates change.
Cold engine starts use the most fuel — a warmed-up engine is significantly more efficient. Planning your errands as a single loop (grocery store, pharmacy, dry cleaner in one trip) instead of separate trips on different days can cut fuel use by 20–30% for local driving.
If you commute 30 miles round-trip daily, working from home just one extra day per week saves roughly 120 miles per month — about $15/month or $180/year at average efficiency and gas prices. Many employers now offer flexible work arrangements.
Cards like the Citi Custom Cash (5% at gas stations), Blue Cash Preferred from Amex (3%), or Costco Anywhere Visa (4% at gas stations) can save $50–$150/year with zero extra effort. If you're already spending $150/month on gas, a 5% card saves $90/year.
If you're spending $250+/month on gas, a more fuel-efficient vehicle could pay for itself in fuel savings faster than you might expect. Switching from a 15 MPG truck to a 30 MPG sedan saves about $175/month at $3.50/gallon — that's $2,100/year.
