The Subaru Forester pairs a tall, practical body with standard all-wheel drive, making it a favorite for families and outdoor types alike. The running-cost question is a fair one: how much does a Subaru Forester cost in gas per year?
Like its Outback sibling, the Forester is efficient for a capable AWD crossover, which keeps the fuel bill friendly. Here is the real annual cost, broken down by mileage.
How much does a Subaru Forester cost in gas per year?
Your annual fuel bill comes down to three things: how far you drive, what you pay per gallon, and the vehicle’s MPG. The Subaru Forester returns about 29 MPG combined, so here is what a year of driving costs at three common mileage levels, using the current national average of roughly $3.91 a gallon.
| Miles driven per year | Annual gas cost | Per month |
|---|---|---|
| 10,000 miles | $1,348 | $112 |
| 12,000 miles | $1,618 | $135 |
| 15,000 miles | $2,022 | $169 |
So the typical driver spends around $1,820 a year, or about $152 a month, on gas in a Subaru Forester. That works out to roughly $0.13 per mile in fuel alone. Pay less than the national average where you live and the bill drops; at $3.50 a gallon the 13,500-mile figure falls to about $1,629, while at $4.50 it climbs to around $2,095. Check what you actually pay on the live gas price tracker and plug it into the gas cost calculator for a number matched to your driving.
Zoom out and the figure gets your attention. Over five years, a typical Subaru Forester driver spends roughly $9,101 on gas alone, and a decade of ownership close to double that. That is real money, which is exactly why fuel economy deserves a place in the buying decision alongside the sticker price and the monthly payment. A thriftier trim, or a hybrid version where one exists, quietly pays you back at every fill-up.
What kind of MPG does the Subaru Forester really get?
Recent Subaru Forester models earn an EPA combined rating of around 29 MPG, roughly 26 in the city and 33 on the highway, strong figures for a boxy compact SUV with standard all-wheel drive. Its tall shape costs a little aerodynamic efficiency at highway speed, but the efficient engine keeps the overall number competitive.
Keep in mind that the window-sticker number is a lab figure. Real-world mileage usually lands 10 to 15% lower, shaped by short trips, cold starts, aggressive acceleration, roof racks, and under-inflated tires. The honest way to know your Subaru Forester’s number is to measure it: fill up, note the odometer, and run the math through the MPG calculator, then confirm the gallons any trip will use with the fuel consumption calculator.
Monthly, weekly, and per-mile cost
Big annual numbers are easy to ignore, so break them down. At the typical 13,500 miles a year, a Subaru Forester runs about $152 a month and roughly $35 a week in gas. On a per-mile basis that is about $0.13, but fuel is only part of what a mile really costs. Tires, oil, brakes, and depreciation stack on top, which is why the cost per mile calculator gives a truer picture of ownership. If most of your miles are a daily commute, the commute cost calculator shows exactly what that drive adds up to each month.
Here is a concrete example. A 30-mile round-trip commute five days a week comes to about 7,800 miles a year, which in a Subaru Forester means roughly $1,052 in commuting fuel alone, before you drive anywhere on the weekend. Small changes to that daily routine, carpooling twice a week, trimming one errand trip, or working from home a day, translate straight into fuel savings you can feel.
What changes your Subaru Forester’s yearly fuel bill
Miles driven. This is the biggest lever by far. A 20,000-mile-a-year driver spends nearly double what a 10,000-mile driver does in the same vehicle, no matter how efficient it is.
Local gas prices. Where you live matters enormously. The same Subaru Forester costs hundreds more per year in high-price states like California than in cheaper states. Compare your state on the gas prices by state page to see where you fall.
City versus highway. The Subaru Forester’s highway number beats its city number, so a driver stuck in stop-and-go traffic burns more than the combined rating suggests. Smooth, steady highway miles are the cheapest kind, and in dollar terms a mostly-city driver can spend a few hundred dollars a year more than a highway commuter in the very same vehicle.
Fuel grade. Good news here: the Subaru Forester is designed to run on regular unleaded, not premium, so you are already buying the cheapest grade at the pump. Cars that require premium can cost hundreds more a year, so sticking with regular where the manufacturer allows it is a saving many drivers overlook.
Driving style and upkeep. Hard acceleration, speeding, and a neglected air filter or soft tires all quietly raise the bill. Gentle inputs and basic maintenance protect the MPG you paid for.
How the Subaru Forester compares
In the compact-SUV class, the Forester is right in the efficient tier, and its standard all-wheel drive makes that more impressive. Many AWD rivals sit a few MPG lower, so the Forester’s ~29 combined means a smaller yearly fuel bill while still delivering the traction and space buyers want.
If you are curious whether an electric vehicle would be cheaper to run than the Subaru Forester, the EV vs gas by state tool lays the two side by side using your local energy and fuel prices, which is the only fair way to compare.
How to cut your Subaru Forester’s gas costs
- Keep roof rails clear of unused cargo boxes; the tall roofline already costs some highway MPG.
- Keep tires inflated to protect the AWD system’s efficiency.
- Buy on cheaper days with our best day to buy gas guide and a gas price app.
- Measure your real mileage with the MPG calculator.
- Compare your state on the gas prices by state page.
Does fuel economy matter when buying a Subaru Forester?
More than most buyers realize. Two versions of the same vehicle with different MPG can differ by hundreds of dollars a year at the pump, and over a typical ownership period that gap can rival the price difference between trims or engines. When you compare a Subaru Forester against rivals, or one Subaru Forester engine against another, it pays to look past the monthly payment and fold the yearly fuel cost into the total. A slightly pricier but thriftier version often costs less to own once the gas is counted.
This is also where a hybrid, a smaller engine, or an efficient drivetrain earns its keep. Run the versions you are considering through the gas cost calculator side by side, and if you are open to going electric, the EV vs gas by state tool shows how charging would compare with fueling a Subaru Forester where you live.
So, is the Subaru Forester cheap to run?
Yes, for a rugged compact SUV with standard all-wheel drive. The Forester keeps running costs reasonable while offering the space, visibility, and all-weather grip that draw buyers to it, a genuinely practical, economical package.
How we calculate these figures
The math is transparent: annual gas cost = (miles driven ÷ combined MPG) × price per gallon. We use the Subaru Forester’s combined fuel-economy rating from the EPA’s official ratings for recent model years, an assumed 13,500 miles a year (close to the U.S. average), and the current national average pump price of about $3.91 a gallon. Change any input and the total changes with it.
Pump prices trace to the U.S. Energy Information Administration (EIA) weekly retail survey, refreshed on our state price pages every business day. For your exact trim, engine, and model year, confirm the EPA rating and measure your real-world MPG with the MPG calculator. Read how we source everything on our methodology and sources pages.
