Cessna 172 vs 182 — Which One Should You Actually Buy?

The Quick Answer — Which Cessna Should You Buy?

The Cessna 172 vs 182 debate comes up in almost every hangar conversation I’ve had over the past decade, and my answer has gotten less diplomatic over time. Buy the 172 if you’re training, building hours, or flying solo most of the time. Buy the 182 if you regularly need to haul three adults, actual luggage, and land at airports above 3,000 feet density altitude without white-knuckling the climb out. Those are two genuinely different missions, and pretending one airplane covers both equally well doesn’t help anyone.

I owned a 1978 Cessna 172N for four years before stepping into a partnership on a 1998 Cessna 182S. The jump felt significant on paper — 160 horsepower versus 230, fixed pitch versus constant-speed prop, roughly $85,000 versus $210,000 in today’s market. In practice, the differences showed up in places I didn’t fully expect. Some in my favor. A few that cost me money before I figured out what I was dealing with.

This isn’t a spec-sheet comparison. You can find those anywhere. This is what it actually feels like to own and operate both airplanes, with real numbers attached.

Engine and Performance — 160 HP vs 230 HP in Practice

Surprised by how little the horsepower difference mattered on a calm morning at sea level — that was me, the first time I flew a 182. Standard conditions flatter both airplanes. The real separation shows up the moment the conditions stop cooperating.

The 172N’s Lycoming O-320-H2AD produces 160 horsepower. The 182S runs a Lycoming IO-540-AB1A5 making 230 horsepower with fuel injection and a constant-speed prop. On paper that’s a 44% power increase. In practice, at 5,500 feet density altitude on a 95-degree afternoon in Colorado, it’s the difference between climbing at 400 feet per minute and climbing at 900.

Here are the book numbers, which track reasonably close to what I’ve seen in real conditions:

• Cessna 172S (current production baseline): Sea-level climb rate 730 FPM, cruise at 75% power approximately 122 knots, service ceiling 14,000 feet
• Cessna 182T (current production baseline): Sea-level climb rate 924 FPM, cruise at 75% power approximately 145 knots, service ceiling 18,100 feet

The cruise speed gap — roughly 23 knots — adds up on a four-hour cross-country. That’s nearly 90 miles. If you’re flying 200-mile trips, it matters less. Flying 500-mile trips regularly, the 182 starts making a scheduling argument.

What the book doesn’t capture is how the constant-speed prop changes the character of the airplane. The 172’s fixed-pitch prop is simple, honest, and forgiving. You set power, you get what you get. The 182 asks you to manage both throttle and prop, which adds a small workload but gives you genuine efficiency control at cruise altitudes. Lean it properly at 8,500 feet and you’ll see 14 GPH instead of 16. That discipline pays off over time.

The IO-540 is also a fuel-injected engine, which eliminates carburetor ice as a concern and makes hot starts a specific skill to develop. I flooded the engine twice in my first month before I got the starting procedure dialed in. Embarrassing at a busy FBO ramp. Worth mentioning.

Density Altitude — Where the 172 Gets Honest

Take a fully loaded 172 to Leadville, Colorado (KLXV, field elevation 9,927 feet) on a warm summer day and you’re looking at density altitudes above 12,000 feet. The airplane will fly. It will not impress you. Climb rates in the 100–200 FPM range are real, and obstacle clearance becomes an actual planning item rather than a formality.

The 182 at the same airport on the same day climbs out at 400–500 FPM. Still not aggressive. Still requires planning. But it’s a different conversation when you have three people and bags in the back.

What Four Adults Actually Feels Like in Each Airplane

Probably should have opened with this section, honestly, because this is where most buying decisions should start and rarely do.

The Cessna 172 has a published useful load that varies by year and equipment, but on a typical mid-1970s to 1980s model you’re looking at around 880 pounds. Modern 172S models come in around 878 pounds. The 182 — depending on year and avionics configuration — typically lands between 1,050 and 1,100 pounds of useful load.

Let’s do the weight and balance math that brochures skip.

Four average adults at 190 pounds each equals 760 pounds of people. Add 60 pounds of luggage — two bags per couple, nothing unreasonable — and you’re at 820 pounds of payload before you touch the fuel caps.

• 172 with 880 lb useful load: 820 lb payload leaves 60 lbs for fuel. That’s roughly 9 gallons. You are not going anywhere useful. This is a local flight at best.
• 182 with 1,100 lb useful load: 820 lb payload leaves 280 lbs for fuel. At 6 lbs per gallon, that’s about 46 gallons. Full tabs on a 182 hold around 56 usable gallons. You can fly 2.5 to 3 hours with reasonable reserves.

The 172 is a two-adult airplane with full fuel. Sometimes two adults and two kids with reduced fuel. The moment someone starts talking about “flying four people to the mountains for the weekend,” the 172 requires an honest conversation about fuel stops, weight limits, and left-behind luggage. I’ve had that conversation. It doesn’t go well at the FBO parking lot when someone pulls up with a hard-sided Rimowa.

The 182 isn’t a cargo hauler either. But it makes four-seat flying actually work in the real world rather than theoretically on paper.

Cabin Space — The Part Nobody Measures

Both airplanes share essentially the same cabin width — about 40 inches. Rear seat legroom is comparable. The 182 sits slightly higher and some pilots find the view and entry easier, but the difference is marginal. Neither airplane is comfortable for a six-foot-four passenger in the back for more than two hours. That’s just the Cessna four-seat reality.

Annual Cost of Ownership — The Numbers Nobody Talks About

I tracked every dollar I spent on both airplanes. Not because I’m obsessive — because my wife asked me to justify the 182 partnership and I needed hard numbers. Here’s what 100 hours per year actually looks like on each.

Fuel Costs

The 172 burns 8–10 GPH depending on power setting and altitude. Call it 9 GPH as a realistic average. The 182 burns 13–14 GPH at cruise, sometimes 15 if you’re not leaning aggressively. Call it 13.5 GPH as a working number.

At $6.50 per gallon avgas (roughly the national average as of late 2024 at self-serve pumps, though it varies wildly by region — I’ve paid $5.20 in Kansas and $8.90 in California):

• 172 fuel cost per hour: $58.50
• 182 fuel cost per hour: $87.75
• Annual fuel difference at 100 hours: approximately $2,925

Insurance

This one surprised me more than anything else. My 172N insurance through Avemco ran $1,100 per year with a $0 in-motion deductible and $100,000 smooth hull. When I joined the 182S partnership — same pilot certificate, same ratings, same hours — the quote came in at $3,200 for my half of a partnership policy on a $210,000 hull. The insurer cited the high-performance endorsement requirement, higher hull value, and higher replacement parts cost.

Insurance on a 182 also reacts more sharply to pilot experience. New private pilots with under 300 hours often face either declined coverage or premiums that make the airplane genuinely unaffordable. The 172 is more forgiving in the underwriting room.

Annual Inspection and Maintenance

A basic annual inspection on a 172 at a shop that charges $95/hour runs $800–$1,200 if the airplane is clean and nothing needs fixing. Add a few squawks and you’re at $1,500–$2,000. A 182 annual starts around $1,200–$1,600 and climbs faster because the IO-540 has more cylinders, the constant-speed prop requires its own inspection cycle, and parts cost more. Budget $2,000–$3,000 for a clean 182 annual.

Engine reserve is where the numbers get serious. The Lycoming O-320 or O-360 in a 172 has a TBO of 2,000 hours and a factory overhaul runs roughly $18,000–$22,000. That’s $9–$11 per hour in engine reserve. The IO-540 in the 182 has a 2,000-hour TBO as well, but a factory overhaul costs $28,000–$35,000 depending on what they find. Reserve $14–$18 per hour.

The Annual Cost Table — 100 Hours

That $70 per hour gap is real and it compounds. Flying 100 hours a year, the 182 costs roughly $7,000 more to operate. Over a five-year ownership period, that’s $35,000 in additional operating costs before you even consider acquisition price. A used 182 can cost $80,000–$125,000 more than a comparable 172 depending on year and avionics. The total ownership cost gap over five years can easily exceed $150,000.

Whether that’s worth it depends entirely on whether you’re using the capability. If you’re flying four people to mountain airports four times a year, the answer is probably yes. If you’re flying solo on $100 hamburger runs, you’re paying for a truck you’re using as a sedan.

The High-Performance Endorsement Question

Federal regulations require a high-performance endorsement — documented in your logbook from a CFI — to act as pilot in command of any aircraft with more than 200 horsepower. The 182’s IO-540 at 230 HP triggers this requirement. The 172 does not.

This matters less than people make it out to matter, but it’s not nothing.

Getting the endorsement typically takes 3–5 hours of dual instruction focused on constant-speed prop operation, power management, and the specific performance characteristics of a high-HP airplane. At $200–$250 per hour for an instructor plus aircraft rental, budget $600–$1,250 to get it done properly. I did mine in a rented 182RG over two afternoons with a CFII in Scottsdale. Logged 4.2 hours dual. Cost $920 all-in.

The endorsement is a one-time cost and there’s no written test or checkride — just a logbook sign-off from a CFI who determines you’re proficient. It’s also not airplane-specific, meaning once you have it, you have it for any high-performance aircraft.

What it does create is a gatekeeping moment. If you’re a student pilot or fresh private pilot who wants to buy a 182 immediately, you need to plan for this step. Rental 182s for endorsement training aren’t at every airport. Some insurance policies also require a minimum number of high-performance hours before they’ll write coverage, which creates a chicken-and-egg problem if you’re trying to insure a 182 you just bought with no time in type.

The practical path for most people — if the 182 is the airplane you want to own — is to get the endorsement in a rental 182 before buying. Arrive at closing with 10–15 hours of 182 time in your logbook and you’ll have fewer insurance problems.

Resale Value and Market Availability

The 172 is the best-selling airplane in history. Cessna has built over 44,000 of them. That market depth means you can find a 172 in almost any configuration, year, and price point within a few weeks of looking. It also means the market is liquid — if you need to sell, you can.

Approximate price ranges for common model years as of late 2024:

• 1968–1975 Cessna 172 (C-K models): $35,000–$55,000
• 1976–1986 Cessna 172N/P: $55,000–$80,000
• 1996–2006 Cessna 172R/S (Lycoming IO-360): $130,000–$185,000
• 2010+ Cessna 172S: $220,000–$290,000 new-ish

The 182 commands a consistent premium across all years:

• 1961–1975 Cessna 182 (E-P models, O-470 engine): $45,000–$75,000
• 1977–1986 Cessna 182Q/R (O-540 era): $70,000–$105,000
• 1997–2006 Cessna 182S/T (IO-540): $185,000–$260,000
• 2010+ Cessna 182T: $310,000–$420,000

Beaten up by the sheer number of airplanes that have come and gone from these fleets, the older 172 and 182 models have actually held value remarkably well over the past decade. The general aviation supply crunch, combined with ballooning new-aircraft prices from Cessna’s parent company Textron, has pushed used prices up significantly since 2019.
