2018 Nissan Altima: True Cost of Ownership (5-Year Breakdown)
The 2018 Nissan Altima is a midsize sedan that blends comfortable daily driving with reasonable running costs, making it a popular choice for commuters and small families seeking a proven, affordable alternative to the Camry or Accord. At around $16,500 on the used market, it sits in a sweet spot for budget-conscious shoppers who still want modern safety tech and a spacious interior. This guide breaks down every real dollar you'll spend owning one over five years.
Monthly cost breakdown
The 2018 Altima has already absorbed most of its steepest depreciation, having lost roughly 55-60% of its original MSRP by now; from a $16,500 purchase price, expect it to be worth approximately $8,500-9,500 at the end of a 5-year ownership period, a relatively modest further drop.
Pros
- Low purchase price of ~$16,500 means minimal loan exposure and lower comprehensive insurance premiums
- Fuel economy of 27 city / 38 highway MPG (2.5L) keeps monthly fuel costs competitive in its class
- Routine maintenance costs are below average — Nissan parts are widely available and labor rates at independent shops are affordable
- Already past peak depreciation curve, so resale loss over your ownership window is relatively contained
Cons
- CVT replacement can cost $3,500-5,000 out of pocket if it fails outside warranty — a significant financial risk on a used purchase
- Reliability rankings for this generation sit below Toyota Camry and Honda Accord peers, meaning slightly higher expected repair frequency after 100,000 miles
- Insurance costs, while moderate, are slightly elevated compared to a comparable Corolla due to higher theft rates for Altimas in some metro areas
- Resale value trails class leaders like the Camry by roughly $1,500-2,500 at the 5-year mark, compounding the total cost disadvantage slightly
Common problems to watch for
- CVT transmission reliability issues — the Xtronic CVT is the most-reported concern, with some owners experiencing shuddering, hesitation, or failure between 80,000-120,000 miles; a pre-purchase inspection should include a thorough CVT fluid check
- Excessive oil consumption on the 2.5L QR25DE engine — some owners report needing to add a quart of oil between changes; monitor levels closely and ask for service history
- Timing chain stretch — reports of timing chain rattle on startup, particularly on higher-mileage examples; listen carefully during a test drive
- Brake wear — front pads and rotors tend to wear faster than segment average, budget for replacement around 40,000-50,000 miles
- Interior trim and infotainment connectivity issues — Bluetooth pairing glitches and cracking dashboard trim are recurring minor complaints on this generation
The verdict
The 2018 Altima is a cost-effective choice if you buy a well-documented, lower-mileage example and set aside a small emergency fund for potential CVT issues. At roughly $512 per month all-in, it undercuts many rivals on total cost, but the CVT risk is real and separates it from the near-worry-free ownership experience of a similarly priced Camry or Accord. Shoppers who do their homework, get a pre-purchase inspection, and change the CVT fluid proactively will likely find it delivers solid value over five years.
Best for: The 2018 Nissan Altima is best for a budget-minded daily commuter or small family driver who wants a spacious, fuel-efficient sedan at a low entry price and is comfortable budgeting for potential CVT maintenance.

Frequently asked questions
Is the 2018 Nissan Altima CVT reliable at high mileage?
The Xtronic CVT is the biggest reliability wildcard on this model — it can last well past 150,000 miles with regular fluid changes every 30,000-40,000 miles, but neglected units are known to fail in the 80,000-120,000 mile range, costing $3,500-5,000 to replace.
How much does it cost to insure a 2018 Nissan Altima?
National average full-coverage insurance for a 2018 Altima runs approximately $1,250-1,450 per year ($104-121/month), though rates vary significantly by ZIP code, driving history, and the owner's age.
What is the fuel cost per year for a 2018 Nissan Altima at 12,000 miles?
At 12,000 miles per year and a blended real-world average of about 30 MPG, you'll use roughly 400 gallons of regular unleaded annually — at $3.50/gallon that's approximately $1,400 per year or about $117 per month.
How much will a 2018 Nissan Altima depreciate over 5 years from a $16,500 purchase?
From $16,500, the Altima is projected to be worth approximately $8,500-9,500 after five more years of ownership and typical mileage, representing a total depreciation loss of roughly $7,000-8,000 over that period.
What routine maintenance should I budget for on a 2018 Altima over 5 years?
Budget for oil changes every 5,000-7,500 miles (~$600-750 total), one or two sets of front brake pads and rotors (~$400-700), tires (~$600-800 for a full set mid-ownership), cabin and engine air filters, and proactive CVT fluid changes (~$150-200 each) — totaling roughly $3,500-4,500 over five years.
Is a 2018 Nissan Altima a good buy compared to a 2018 Honda Accord or Toyota Camry?
The Altima wins on purchase price and can be $2,000-4,000 cheaper to acquire, but the Camry and Accord both offer more reliable transmissions, stronger resale values, and higher owner satisfaction scores — if budget allows, the Accord or Camry deliver better long-term value, but the Altima is a reasonable trade-off for shoppers prioritizing lower upfront cost.
