What is the Subaru Solterra 5-year cost of ownership in 2026?
Based on a Popular-trim purchase at $47,500 with a 20% down payment, a 5-year loan at the national average new-car APR, 12,000 miles per year, and national average tax and insurance, the estimated 5-year cost of ownership is $57,672 — about $11,534 per year — with an estimated $17,575 residual value after 5 years. Use the calculator above to tailor it to your state, down payment, and mileage.
How much does a Subaru Solterra depreciate each year?
The Solterra sits in the ev segment. Applying a segment-average retention curve, it is estimated to keep roughly 78% of its value after the first year and 37% after five years. Depreciation is typically the single largest ownership cost, which is why our calculator shows it year by year alongside every other expense.
What is the Subaru Solterra MSRP and which trims are available?
The Solterra ranges from $45,000 (Base (entry trim)) to $50,000 (Top (fully loaded)). Trims shown: Base (entry trim) ($45,000); Popular (mid trim) ($47,500); Top (fully loaded) ($50,000). Select a trim in the calculator to recompute costs instantly.
Is the Subaru Solterra eligible for a federal or state EV tax credit in 2026?
The federal clean-vehicle tax credit ended September 30, 2025, so new EVs no longer qualify at the point of sale in 2026. Some states and local utilities still offer rebates — check your state's page for current incentives. The Solterra's lower energy and maintenance costs help offset the lost federal credit.
What are the Subaru Solterra energy costs?
The Solterra is EPA-rated at 104 MPGe, about 32 kWh per 100 miles. At the 2026 U.S. average of $0.16/kWh that is roughly $3,110 in electricity over 5 years (12,000 miles/year). EVs also skip oil changes, lowering maintenance.
How do Subaru Solterra ownership costs compare with rivals?
See the side-by-side comparison table on this page. We model the Solterra against Hyundai Ioniq 6, Tesla Model 3, Toyota bZ4X, Nissan Ariya using identical assumptions — same annual miles, down payment, and loan terms — so the difference is truly apples-to-apples.
