The short answer first
Over five years, this Lexus RX example costs about $74,018 in total, or about $1,234 a month. The monthly loan payment is $1,087, and that payment is only part of the story. Insurance, gas, upkeep, and the value the car loses add about $147 a month on top of the payment when spread across five years. Everything below shows where each dollar comes from, so you can swap in your own quote and see your own number.
Start with the price you will actually pay
For a representative example, use a 2025 Lexus RX 350 Premium AWD at $54,325. Kelley Blue Book and a Lexus dealer pricing overview both list $54,325 for this trim, so the price is backed by two sources. Two cautions stated plainly: this page does not claim that $54,325 includes the delivery (destination) charge, because sources disagree on that point, Edmunds lists $52,975 for the same trim, a $1,350 gap that looks like a difference in how delivery is handled. And Kelley Blue Book's fair-purchase figures suggest buyers often pay less than the sticker price, so a written quote for your exact RX could come in lower and would lower the total below.
The down payment does not make the RX cheaper; it changes how much you finance. With 10% down ($5,433), 7% sales tax ($3,803), $900 in title and dealer fees, and an 8% APR (the yearly interest rate on the loan) over 60 months, this example finances $53,595 at $1,087 a month, and the loan costs about $11,608 in interest over five years.
This is the gas (non-hybrid) RX 350, a 2.4-liter turbocharged four-cylinder with all-wheel drive (power to all four wheels). The hybrid RX 350h is a different car with different gas mileage, and its numbers are kept separate below, never mixed into this example.
Fuel: premium gas at today's premium price
The RX 350 AWD is rated 24 mpg combined (21 city, 28 highway, EPA-estimated). At 12,000 miles a year that is 500 gallons a year. This example prices premium unleaded gas (higher-octane gas) at $5.19 a gallon, the AAA national average premium price of $5.1858 on October 22, 2026, which comes to about $2,595 a year, $12,975 over five years.
One honest wrinkle: sources disagree on whether premium is strictly required. The EPA lists the RX 350's fuel type as premium, and dealer listings describe premium gasoline, but other sources say unleaded gas rated 87 or higher is acceptable and premium is recommended for best performance. This example budgets premium, the more expensive case. If your owner's manual allows regular gas and you run it, fuel drops, at the site's $4.071-a-gallon planning figure (EIA national average, week ending August 31, 2026), the same miles cost $10,178 over five years. Check your manual before deciding.
Depreciation: the RX's strongest card
Depreciation is the value a car loses over time, usually the biggest single cost of owning a new car, and the RX loses less than most luxury SUVs. Data reported from iSeeCars puts the RX's five-year value loss at about 38.9%, it keeps roughly 61% of its price. On a $54,325 purchase, that means a resale value of about $33,193 after five years and about $21,132 of depreciation, roughly $352 a month.
Other sources bracket that figure rather than contradicting it outright: CarEdge projects a smaller 33% loss for the RX 350, while Edmunds' cost-to-own work for this exact trim shows $22,717 of depreciation on its lower $52,975 price (about 43%). This example uses the middle 38.9% figure. Resale is a planning assumption, not a promise, run a second scenario with resale 10% lower so the decision does not depend on an optimistic used market.
Insurance runs luxury-SUV money, but not the worst in its class
Full-coverage averages for the RX 350 cluster between about $201 a month (Insuraviz) and $219 a month (The Zebra, 2025 model). This example uses $210 a month, or $12,600 over five years. Premiums depend heavily on the driver, ZIP code, coverage, and insurer, so get a quote on the exact trim with matching deductibles and limits before treating any average as yours.
RX maintenance costs: routine, with a luxury-sized tire bill
Edmunds' five-year cost-to-own work for this exact trim puts maintenance at $9,805 plus $1,252 in repairs, about $11,057 combined. Kelley Blue Book's work on a related RX 350 trim lands a little lower, near $9,793 combined. This example allows $2,200 a year, or $11,000 all-in, routine service, plus wear items. One realistic item inside that allowance: a set of large luxury-SUV tires inside five years at 60,000 miles. The RX's reputation for reliability helps here, but tires and brakes are wear items on every car, whatever the badge.
The full five-year example
Every figure below comes from the same calculator math. The stated inputs are: 2025 Lexus RX 350 Premium AWD, $54,325 price, 10% down ($5,433), 8% APR, 60 months, 7% sales tax, $900 in title and dealer fees, 12,000 miles per year, 24 mpg, premium gas at $5.19 per gallon, $210 per month insurance, $2,200 per year maintenance, $33,193 resale value after five years.
- Depreciation (the value it loses): $21,132 ($54,325 minus $33,193 resale)
- Insurance: $12,600 ($210 x 60 months)
- Fuel: $12,975 (12,000 / 24 x $5.19 x 5 years)
- Maintenance (upkeep): $11,000 ($2,200 x 5 years)
- Tax, fees and interest: $16,311 ($3,803 sales tax, $900 fees, $11,608 loan interest)
That totals roughly $74,018, or about $1,234 a month. Notice what that says about the $1,087 payment: on this vehicle the payment is not the whole story, it is about 88% of the average month's true cost, and during the loan years the cash actually going out is the payment plus insurance, fuel, and upkeep.
Formula
The five-year total is the sum of five buckets: depreciation, insurance, fuel, maintenance, and tax, fees and interest. Depreciation is the $54,325 price minus the $33,193 resale value after five years, which is $21,132. Insurance is $210 a month times 60 months, which is $12,600. Fuel is 12,000 miles a year divided by 24 miles per gallon, times $5.19 a gallon for premium, times 5 years, which is about $12,975. Maintenance is $2,200 a year times 5 years, which is $11,000. Tax, fees and interest is 7% sales tax on $54,325, which is $3,803, plus $900 in title and dealer fees, plus about $11,608 of loan interest, which is $16,311.
Added together, $21,132 plus $12,600 plus $12,975 plus $11,000 plus $16,311 equals $74,018, or about $1,234 a month. The amount financed is the $54,325 price plus $3,803 sales tax plus $900 in fees, minus the $5,433 down payment, which is $53,595. At 8% APR over 60 months, the payment on $53,595 is $1,087 a month, and the loan costs about $11,608 in interest over five years.
What about the hybrid RX 350h?
The RX 350h is rated 36 mpg combined, and at the same $5.19 premium price its fuel over five years would be about $8,650 (12,000 / 36 x $5.19 x 5 years), about $4,325 less fuel than the gas RX 350 in this example. Its Premium trim lists at $54,725, about $400 more than the gas Premium AWD used here. Those are the hybrid's own numbers, shown for comparison only; they are not blended into the $74,018 total above. Whether the hybrid wins for you depends on your miles, your gas price, and the quote you actually get, the EV vs. gas guide shows the same miles-divided-by-mpg math.
Why RX buyers should think past year five
The RX is often kept a long time, and that is where the economics can improve: the loan ends at year five, and the depreciation curve flattens as the car holds its value better than most rivals. The costs that arrive in years six through ten are the wear-and-repair years: a second tire set, brakes, and suspension work. The keep it 10 years guide shows how to extend this same math honestly, and the why cars lose value guide explains the biggest bucket in plain words.

Calculation transparency
Jurisdiction. United States. Sales tax, titling, registration and insurance rules are set by your state, so your exact numbers depend on where you buy and register the car. The 7% sales tax and $900 in fees in this example are planning figures, not any one state's actual rates.
Rules and time period. Five years, 12,000 miles a year, premium gas at $5.19 a gallon (AAA national average for premium, October 22, 2026), 8% APR, 60 months, 10% down. The resale value is a planning assumption, not a forecast.
Scope and limitations. Educational estimate only. Insurance and maintenance are planning figures, not quotes. Get a real quote for the same trim, coverage and loan before you decide.
Sources disagree on the RX's five-year value loss: iSeeCars puts it at 38.9 percent while CarEdge puts it near 33 percent, and Edmunds' cost-to-own work shows $22,717 of depreciation on its lower $52,975 price, so the 38.9 percent figure used here is kept as a planning assumption, not as a current reading. The $54,325 example price also sits above Edmunds' $52,975 listing for the same trim, a $1,350 gap that looks like a difference in how delivery is handled, and it is kept as printed.
