2026 Infiniti QX80 Lease vs Buy: Why the Same Monthly Payment Costs $28,000 More
The $1 Monthly Difference That Hides a $28,000 Decision
Picture this: you're sitting across from a finance manager at an Infiniti dealership. The 2026 QX80 Luxe AWD just got a full redesign. It looks fantastic. The manager slides a paper across the desk showing two options — lease at $1,335/month with $5,000 down, or finance at $1,336/month with $16,946 down. "Almost the same payment either way," he says with a shrug.
He's not lying. But he's also not showing you the part that actually matters.
The 5-year net cost difference between those two options — on this specific truck, at current rates — is $27,934. That's a number no dealership is going to volunteer, and it's a number you cannot calculate in your head at the desk.
This is the math.
Who the 2026 QX80 Actually Is (And Why That Matters for Resale)
The newly redesigned 2026 Infiniti QX80 reviewed by The Drive lands in an uncomfortable position: better than the Nissan Armada it's built on, but not quite at Cadillac Escalade or Lincoln Navigator level. The review describes it as a vehicle that "stuck the landing" on its redesign without quite earning a seat at the top table of premium full-size SUVs.
That positioning matters enormously when you're making a lease vs. buy decision.
Here's why: luxury SUV residual values are brutally sensitive to brand perception. We just watched Porsche — one of the most storied automotive brands on the planet — report that its dismal 2025 sales figures have carried into Q1 2026 with no sign of recovery. That kind of sustained sales weakness doesn't just hurt the automaker's revenue. It hammers used car prices and crushes the residual assumptions that were baked into lease agreements 3 years ago. (If you're cross-shopping with a 2026 Porsche Cayenne and wondering whether to lease or buy, we've done that math separately — and the brand-risk angle changes the calculus completely.)
Infiniti sits in a similar gray zone. It's a legitimate premium brand with a loyal base, but its resale values have historically trailed German and domestic luxury competitors. If you're buying a QX80 to own it for 7 years, that's probably fine. If you're buying it and expecting to trade in at year 3 or 4, the depreciation math can sting.
That's exactly the context you need before we run the numbers.
The Worked Example: 2026 Infiniti QX80 Luxe AWD
Starting point: MSRP of $87,350 for the Luxe AWD trim. Negotiated selling price at 3% below sticker: $84,730. These are realistic numbers based on the redesigned model's current market position.
Lease Scenario (36 Months)
| Variable | Value |
|---|---|
| Capitalized cost | $84,730 |
| Cap cost reduction (down payment) | $5,000 |
| Adjusted cap cost | $79,730 |
| Residual value (50% of MSRP) | $43,675 |
| Money factor | 0.00183 (~4.4% APR equivalent) |
| Monthly depreciation portion | $1,002 |
| Monthly finance charge | $226 |
| Pre-tax monthly payment | $1,228 |
| With 8.75% sales tax | $1,335/month |
Total cash out over 36 months: $5,000 + (36 × $1,335) = $53,060 What you own at month 36: $0
This is the part that feels abstract until you see it next to the alternative.
Buy Scenario (60-Month Loan)
| Variable | Value |
|---|---|
| Purchase price | $84,730 |
| Down payment (20%) | $16,946 |
| Loan amount | $67,784 |
| APR | 6.9% |
| Term | 60 months |
| Monthly payment | $1,336/month |
Total loan payments: 60 × $1,336 = $80,160 Total cash out over 60 months: $16,946 + $80,160 = $97,106 Estimated vehicle value at month 60 (40% of MSRP): $34,940 Net 5-year cost: $97,106 − $34,940 = $62,166
This is the kind of side-by-side analysis DriveDecision builds automatically — so you're not assembling residual estimates and money factor conversions by hand.
The 5-Year Net Cost Comparison
To compare lease vs. buy fairly, you have to account for what happens after the 36-month lease ends. If you keep leasing — which most lessees do — here's what your 5-year picture looks like:
| Lease (continuous) | Buy (60-month loan) | |
|---|---|---|
| Months 1–36 cash out | $53,060 | $16,946 down + $48,096 payments = $65,042 |
| Months 37–60 cash out | $5,000 CCR + 24 × $1,335 = $37,040 | 24 × $1,336 = $32,064 |
| Total cash out (60 mo.) | $90,100 | $97,106 |
| Asset value at month 60 | $0 | $34,940 |
| Net 5-year cost | $90,100 | $62,166 |
| Difference | — | You keep $27,934 more |
The monthly payments are $1 apart. The 5-year net cost difference is $27,934.
That's the trap. The payment comparison feels like a coin flip. The ownership comparison isn't even close.
So When Does Leasing Actually Win?
This isn't a slam on leasing. There are real scenarios where the lease math flips:
1. If depreciation accelerates beyond the residual assumption. The lease locks in a 50% residual. If Infiniti's brand struggles (see: Porsche) and the QX80 is actually worth $36,000 at month 36 instead of $43,675, the leasing customer walks away clean. The buyer eats the difference.
We've seen exactly this play out with certain EVs — a used 2023 Rivian R1S vs. a Tesla Model Y comparison showed how fleet sales and market oversupply can gut residuals that buyers assumed were stable.
2. If your down payment money earns returns elsewhere. The $16,946 down payment required to buy isn't "free" money — it has an opportunity cost. At 6% annual return, that $16,946 grows to approximately $22,675 over 5 years. That $5,725 in foregone returns narrows the gap somewhat.
3. If you genuinely want a new vehicle every 3 years. The math above assumes you're holding the purchased vehicle for 5 years. If you'd trade in at year 3 regardless, the comparison changes significantly — because early trade-ins trigger depreciation curves that erode the buyer's equity advantage.
4. If your income situation favors the lower effective down payment. The lease asks for $5,000 upfront. The loan asks for $16,946. For buyers where liquidity matters — particularly for a vehicle that isn't a primary financial asset — that $11,946 difference in required capital has real value.
None of these variables are the same for every buyer. A self-employed person with a high-yield brokerage account and a history of trading cars every 3 years has a very different lease vs. buy math than a buyer with stable W-2 income planning to drive the QX80 to 150,000 miles.
The Variables That Change Your Personal Answer
The worked example above is a baseline, but YOUR numbers will shift based on:
- Your zip code: Sales tax rates range from 0% to 10.25% in the U.S. On a $1,228 pre-tax lease payment, that's the difference between $1,228 and $1,354/month — a $45/month swing that compounds to $1,620 over a 36-month lease.
- Your credit tier: The money factor above assumes Tier 1 credit. Drop to Tier 2 and the money factor can jump from 0.00183 to 0.00240 — adding roughly $75/month to your lease payment.
- Your negotiated purchase price: Every 1% below MSRP you negotiate saves you $847 on a $84,730 vehicle. A skilled negotiator getting 5% off changes the monthly payment and the residual basis.
- Your APR on the loan: The 6.9% rate used above is a current national average. Credit union members are seeing rates closer to 5.5%, which drops the monthly buy payment to roughly $1,290 — actually below the lease payment and widening the 5-year gap even further.
- Your annual mileage: Lease residual assumptions are based on 10,000–12,000 miles/year. Drive 18,000 miles/year and your residual drops, your overage penalties add up, and the lease math deteriorates fast.

The Broader Market Context Worth Watching
Two things happening right now in the broader automotive market have direct bearing on the QX80 decision.
First, full-size luxury SUV competition is intensifying. The QX80 is positioned between the Nissan Armada (which shares its platform) and the Cadillac Escalade. That middle-ground positioning can squeeze residuals — we looked at exactly this dynamic in our 2026 Nissan Armada NISMO vs. Toyota Sequoia analysis, where platform overlap and brand hierarchy created pricing pressure that undermined 5-year ownership assumptions.
Second, tariff risk. The QX80 is assembled in Japan, which means it sits squarely in the zone of potential import tariff exposure. Any meaningful tariff increase would raise transaction prices on new inventory, improve residuals on existing leased vehicles, but create serious budget pressure for buyers financing new ones. The lease structure has a natural hedge here: if prices spike in year 4, you didn't commit.
This is also what makes the decision so personal. The "right" answer depends on your view of where Infiniti's residuals land in 2029, where interest rates are heading, how much you drive, and what state you're registering in. A blog post can give you the framework. Only your numbers give you the answer.
The Bottom Line
The 2026 Infiniti QX80 is a genuinely well-executed redesign that fills a real need: premium full-size SUV without German pricing. But the financing decision is where you either keep or lose tens of thousands of dollars.
At current rates and standard terms:
- Lease: $1,335/month, $5,000 down, walk away with nothing after 36 months
- Buy: $1,336/month, $16,946 down, own an asset worth ~$34,940 after 60 months
- 5-year net cost gap: $27,934 in favor of buying
That gap shrinks or reverses if depreciation accelerates, if your money factor is unfavorable, or if your driving habits disqualify you from standard lease terms.
If you've been comparing monthly payments and treating lease vs. buy as a coin flip, you're looking at the wrong number. The payment is the same. The financial outcome isn't.
