2021 Nissan Altima: True Cost of Ownership (5-Year Breakdown)
The 2021 Nissan Altima is a midsize sedan built for budget-conscious commuters and families who want a comfortable, fuel-efficient daily driver without the premium price tag. At around $20,000 on the used market, it sits in a competitive sweet spot offering standard AWD availability, solid tech features, and low running costs. It's ideally suited for high-mileage commuters and cost-focused buyers who prioritize reliability over prestige.
Monthly cost breakdown
The 2021 Altima depreciates at a moderate pace, losing roughly 45-50% of its original MSRP over five years, which is about average for the midsize sedan segment. Starting at a $20,000 used price meaningfully softens the depreciation blow compared to buying new.
Pros
- Exceptional fuel economy of 28 city / 39 highway mpg keeps energy costs well below segment average
- Lower-than-average insurance premiums thanks to strong safety ratings and modest repair costs
- Routine maintenance costs are competitive, with widely available parts and no dealer-only service requirements
- Standard driver-assist safety tech (ProPILOT Assist available) can reduce accident risk and long-term repair expenses
Cons
- CVT transmission has a higher-than-average long-term repair risk and replacement can cost $3,500-$5,000 out of warranty
- Resale value trails segment leaders like the Honda Accord and Toyota Camry by 5-8 percentage points
- Rear seat and cargo practicality limits appeal for growing families, potentially accelerating trade-in timeline
- Nissan's brand reliability scores in J.D. Power surveys sit below segment average, slightly elevating unexpected repair probability
Common problems to watch for
- CVT transmission can exhibit shuddering or hesitation, especially under hard acceleration — a known Nissan weakness worth inspecting
- Some owners report excessive oil consumption on the 2.5L engine, particularly after 60,000 miles — check oil levels regularly
- Infotainment system touchscreen can be laggy and prone to freezing, often requiring a reboot
- Brake wear tends to occur faster than average, with some owners needing pad replacements around 30,000-35,000 miles
- Cabin and wind noise at highway speeds is higher than competitors like the Honda Accord or Toyota Camry
The verdict
At a $20,000 entry price, the 2021 Altima offers genuinely competitive monthly costs and outstanding fuel economy that make it a smart buy for budget-focused drivers. However, the CVT transmission is a real long-term wildcard — a pre-purchase inspection and a look at remaining powertrain warranty coverage are non-negotiables. If those check out, it delivers solid value that few similarly priced sedans can match.
Best for: The 2021 Nissan Altima is best for solo commuters or small families who drive 10,000-15,000 miles per year, prioritize fuel savings and low insurance costs, and want a comfortable sedan without financing a new-car premium.

Does the 2021 Nissan Altima require expensive maintenance?
Routine maintenance is affordable, with oil changes around $40-$60 and a 30,000-mile service typically under $250. The main cost risk is CVT fluid service every 60,000 miles (~$150-$200) and brake pad replacements that may come earlier than expected.
