Alternator Replacement Cost
Alternator Replacement typically costs $290–$1,205 across economy, mainstream and premium vehicles, including reference parts and labor. A warning light does not prove the alternator is bad.
| Vehicle type | Parts | Labor hours | Total |
|---|---|---|---|
| economy | $180–$462 | 1–2.2 | $290–$869 |
| mainstream | $274–$556 | 1.4–2.6 | $428–$1,037 |
| premium | $368–$650 | 1.8–3 | $566–$1,205 |
Labor uses the configured national band of $110–$185/hour. Vehicle windows narrow both reference parts and hours; pickup, full-size SUV and van access can require more labor. This table is a reference estimate, not a complete quote analysis.
