Estimated 5-year cost to own the GMC Sierra 1500
Running cost is only part of ownership. Below is OwnRate's transparent 5-year estimate. The fuel/energy line uses the EPA's published annual fuel cost ($3,650 × 5). The maintenance, insurance and depreciation lines are documented assumptions by body type and powertrain — not model-specific quotes — so treat the total as a ballpark, not a price. See the methodology for the exact assumptions.
| Cost line (5 years) | Estimate |
|---|---|
| Fuel / energy (EPA 5-yr) | $18,250 |
| Maintenance & repairs (est.) | $6,000 |
| Insurance (est.) | $8,500 |
| Depreciation (est.) | $18,000 |
| Estimated 5-year cost to own | $50,750 |
