If you’re looking at an electric SUV with all-wheel drive, it’s natural to ask what the Subaru Solterra cost per mile to drive really looks like. Sticker price is one thing, your day‑to‑day electricity, charging, and maintenance costs are what you’ll feel every month.
Key takeaway
How much does a Solterra cost per mile to drive?
Let’s start with ballpark numbers and then we’ll show our math. Using 2024–2025 U.S. electricity prices and the Solterra’s EPA efficiency, you can expect:
- Home charging average: about $0.07–$0.10 per mile at $0.15–$0.20 per kWh
- Cheap‑electricity scenario: as low as $0.05–$0.06 per mile in markets with ~$0.12 per kWh and off‑peak rates
- Mostly DC fast charging: closer to $0.15–$0.20 per mile, depending on the network
- Comparable gas compact SUV: around $0.14–$0.20 per mile in fuel alone at $3.50–$4.50 per gallon
Quick rule of thumb
How we calculate Subaru Solterra cost per mile
Cost per mile is just energy price multiplied by how much energy the vehicle uses to go a mile. In equation form:
Cost per mile = (kWh used per mile) × (electricity price per kWh)
For example, if your Subaru Solterra uses about 0.30 kWh per mile and your home rate is $0.20 per kWh:
0.30 × $0.20 = $0.06 per mile
To get realistic numbers, we’ll lean on three inputs:
- The Solterra’s EPA MPGe rating (a proxy for efficiency)
- Typical U.S. electricity prices per kWh
- Whether you charge mostly at home, or rely on public fast charging
Don’t over‑trust MPGe
Electricity use: what kind of MPGe does the Solterra get?
The Subaru Solterra shares its platform with the Toyota bZ4X. Depending on trim and wheels, the all‑wheel‑drive Solterra sits roughly in the 94–104 MPGe combined range. For cost‑per‑mile math, we’ll use a middle‑of‑the‑road figure of about 100 MPGe combined.
MPGe to kWh per mile, made simple
Working numbers for Solterra cost-per-mile math
Real‑world drivers often see efficiency in the 0.30–0.36 kWh per mile band. We’ll keep using 0.34 kWh/mi as a realistic planning number, then show you how to plug in your own data later.
Solterra cost per mile at different electricity rates
Now let’s pair that ~0.34 kWh per mile with a few common electricity prices. These are example U.S. residential rates, you should check your own bill for exact numbers.

What this looks like annually
Home charging vs public fast charging costs
Cost per mile for any EV, including the Solterra, shifts a lot depending on how you charge. Home charging is usually cheapest, while DC fast charging on road trips can approach or even match gas‑SUV fuel costs on a per‑mile basis.
Mostly home charging
If you have access to a Level 2 charger on a typical U.S. residential rate:
- Expect roughly $0.05–$0.09 per mile
- 12,000 miles/year ≈ $600–$1,000 in electricity
- Off‑peak plans can shave another 10–30% off those numbers
Installing a home charger is usually a one‑time cost, then you enjoy low, predictable per‑mile costs for years.
Heavy public fast‑charging use
If you rely on DC fast charging (think 150 kW roadside chargers), networks often price electricity more like a premium fuel:
- All‑in prices commonly equate to $0.15–$0.25 per mile in a Solterra
- That can be similar to, or slightly cheaper than, fueling a 25–28 mpg gas SUV at $3.50–$4.50/gal
- Time‑based fees and idle fees can push costs higher if you linger at the charger
Occasional road‑trip fast‑charging is still far cheaper than owning a gas SUV. But if you never charge at home or work, the economic advantage shrinks.

Solterra’s energy savings in plain English
Beyond energy: tires, maintenance, and depreciation
Energy is only one piece of total cost per mile. To really understand Solterra ownership costs, you need to factor in maintenance, tires, insurance, and depreciation.
How non‑fuel costs affect Solterra cost per mile
Energy savings are real, but they share the stage with other line items.
Maintenance
The Solterra has:
- No oil changes
- Fewer moving parts in the drivetrain
- Less brake wear thanks to regen
Over 5–10 years, many owners see lower maintenance cost per mile than a comparable gas Subaru.
Tires
Like many EVs, the Solterra is heavy and torquey. That can mean:
- Shorter tire life if you drive aggressively
- Higher replacement cost for EV‑rated tires
Budget a bit more per mile for tires than you might for a light, low‑power crossover.
Depreciation
Depreciation is the single biggest cost per mile for most new vehicles, EV or not.
Buying a used Solterra with verified battery health can dramatically lower your effective cost per mile compared with buying new.
Don’t ignore insurance
Used Solterra: why battery health matters for cost per mile
If you’re comparing a new Solterra to a used Solterra, the single biggest swing factor for long‑term cost per mile is depreciation. Buy right, and a used EV can deliver luxury‑car smoothness at compact‑car running costs.
Battery health is central here. A healthy pack maintains good range and lets you keep using low‑cost charging options. A heavily degraded pack may push you into more frequent charging or even a costly replacement, which shows up as a big spike in your long‑term cost per mile.
How Recharged helps on used Solterra deals

DIY Subaru Solterra cost‑per‑mile calculator
1. Find your real kWh rate
Grab a recent electric bill and calculate your <strong>total cost divided by total kWh</strong>, including taxes and fees. If you’re on time‑of‑use pricing, note off‑peak and on‑peak rates separately.
2. Decide how many miles you drive
Look at your odometer or past service records to estimate your annual mileage. Many U.S. drivers fall in the <strong>8,000–15,000 miles per year</strong> range.
3. Estimate your Solterra efficiency
Start with <strong>0.34 kWh per mile</strong> as a baseline. If you do a lot of highway driving or live in a very cold climate, consider using <strong>0.36–0.38 kWh/mi</strong> instead.
4. Multiply rate × kWh per mile
Multiply your <strong>average kWh rate</strong> by your <strong>kWh per mile</strong> estimate. That’s your <strong>electricity cost per mile</strong> when charging at home.
5. Account for public charging
If you expect to use DC fast charging regularly, assume those miles cost roughly <strong>2–3×</strong> your home‑charging cost per mile. Estimate what share of your annual miles will be DC fast vs home and blend the two.
6. Add maintenance & other costs
Take your best guess at annual spending on <strong>tires, routine service, registration, and insurance</strong>, then divide by your annual miles. Add this to your energy cost per mile to see a more complete total.
