The lower price also cuts the sales tax and the loan interest: $3,000 off the price, $210 less sales tax, and $559 less loan interest. The monthly cost falls from $884 to $821. December brings the year's biggest incentives and, at the same time, the year's highest average prices, so the discount on your car is decided by the quote, not the calendar.
The worked example: same car, with and without the discount
Same car, same loan terms, same resale value at the end. The only change is $3,000 off the sticker price, for example. Everything else follows from that one change.
| Line | Full price | $3,000 off |
|---|---|---|
| Sticker price | $35,000 | $32,000 |
| Sales tax, 7% | $2,450 | $2,240 |
| Title and dealer fees | $900 | $900 |
| Out the door | $38,350 | $35,140 |
| Loan after $5,000 down, 60 months at 6.5% | $33,350 | $30,140 |
| Loan interest | $5,802 | $5,243 |
| Depreciation (resale $16,800 in both runs) | $18,200 | $15,200 |
| Insurance, 5 years | $10,800 | $10,800 |
| Fuel, 5 years | $8,899 | $8,899 |
| Upkeep, 5 years | $6,000 | $6,000 |
| 5-year true cost | $53,051 | $49,282 |
| Per month | $884 | $821 |
How the total is built: depreciation plus insurance, fuel, upkeep, tax, fees, and loan interest. The sticker price itself is not added on top of depreciation. Depreciation is the price minus the $16,800 resale value, held the same in both runs, so the discount comes straight off depreciation. Basis: the site's standard $35,000 example, 7% sales tax, $900 in title and dealer fees, $5,000 down, a 60-month loan at 6.5%.
Formula
The worked example runs the same car twice, with the same loan terms and the same resale value at the end. The only change is $3,000 off the sticker price. At full price: sticker $35,000, sales tax at 7% $2,450, title and dealer fees $900, out the door $38,350. After $5,000 down, the 60-month loan at 6.5% is $33,350 and costs $5,802 in interest. Depreciation is $18,200, the $35,000 price minus the $16,800 resale value. Insurance is $10,800, fuel is $8,899, upkeep is $6,000. That totals $53,051 over five years, or $884 a month.
With the $3,000 discount: sticker $32,000, sales tax at 7% $2,240, title and dealer fees $900, out the door $35,140. After $5,000 down, the 60-month loan at 6.5% is $30,140 and costs $5,243 in interest. Depreciation is $15,200, the $32,000 price minus the same $16,800 resale value. Insurance, fuel, and upkeep are unchanged at $10,800, $8,899, and $6,000. That totals $49,282 over five years, or $821 a month. The difference between the two totals is $3,769: $53,051 minus $49,282.
The $3,769 is three lines added together: $3,000 off the price, plus $210 less sales tax, plus $559 less loan interest. Sales tax is a percentage of price, so 7% of a $3,000 discount is $210 less tax. The loan is smaller, so 60 months at 6.5% costs $559 less interest. Depreciation is smaller, because the car is worth the same $16,800 at the end either way and you paid less to own that same value. The growth has one condition: resale has to hold. If the discounted car is a slow seller that keeps sliding in value afterward, the resale line falls and eats the gain.
The December market behind the page, Kelley Blue Book figures published January 13, 2026: incentives rose to 7.5% of the average price buyers paid, the highest point of 2025, up from 6.7% in November but below the 7.9% of December 2024. At the same time, the average price buyers paid hit a record $50,326, and the average sticker price hit a record $52,627. Electric cars ran even higher on incentives, 18% of the average EV price paid, a record. Nearly 20% of December buyers bought luxury models, a peak for the year. Incentives peak in December, and average prices peak in December, because December buyers buy pricier cars. A discount is real on a specific car, not a promise on every car.
Why the discount grows past $3,000
Three lines move when the price moves. First, sales tax is a percentage of price, so 7% of a $3,000 discount is $210 less tax. Second, the loan is smaller, so 60 months at 6.5% costs $559 less interest. Third, depreciation is smaller, because the car is worth the same $16,800 at the end either way and you paid less to own that same value. Add them up: $3,000 plus $210 plus $559 is $3,769.
The growth has one condition: resale has to hold. If the discounted car is a slow seller that keeps sliding in value afterward, the resale line falls and eats the gain. That is the other side of a discount, and it is covered on the slowest sellers page, where the same discount math runs on a slow-selling Jeep Compass.
What December actually looked like last year
December 2025, Kelley Blue Book figures published January 13, 2026: incentives rose to 7.5% of the average price buyers paid, the highest point of 2025, up from 6.7% in November but below the 7.9% of December 2024. At the same time, the average price buyers paid hit a record $50,326, and the average sticker price hit a record $52,627. Kelley Blue Book says new-vehicle prices typically peak in December, and points out that the average reflects what was sold, not what was on the lot: nearly 20% of December buyers bought luxury models, a peak for the year. Electric cars ran even higher on incentives, 18% of the average EV price paid, a record.
Read those two facts together. Incentives peak in December, and average prices peak in December, because December buyers buy pricier cars. A discount is real on a specific car, not a promise on every car. That is why the quote comparison below matters more than the month.
When year-end deals appear
The last days of December stack three deadlines at once: the month's, the quarter's, and the year's sales targets. Outgoing model-year cars are the stock dealers most want moved, because the next model year is already on the lot. Holiday sale events are real sales pushes on top of that. The trade-off is selection: as the month runs on, the specific car you want may be gone, and the cars left are the ones nobody picked yet. The full timing picture, month by month and including used cars, is on the cheapest time to buy page.
How to check whether a year-end deal is real
Three checks, all on the same car. First, get the full out-the-door total: price plus tax plus fees, not the monthly payment and not the discount headline. Second, get a second out-the-door quote for the same year, model, and trim. Third, run both quotes through the calculator or the quote check and compare the five-year totals side by side. Two out-the-door quotes for the same car tell you more than any calendar rule.

Calculation transparency
Scope. One worked example, the same car with and without a $3,000 year-end discount, run for five years on stated inputs, plus the Kelley Blue Book December 2025 market figures that set the season in context. The discount math is the page own arithmetic, not a market average.
Rules and time period. Site standard $35,000 example, 7% sales tax, $900 in title and dealer fees, $5,000 down, a 60-month loan at 6.5%, resale $16,800 held the same in both runs. Kelley Blue Book December 2025 figures published January 13, 2026.
Scope and limitations. Educational estimate only. The $3,769 saving holds only if resale holds: if the discounted car is a slow seller that keeps sliding in value afterward, the resale line falls and eats the gain. Prices and incentive rates move, so treat the dated figures as snapshots and check current rates before you buy. Prices vary by car, shop, and city.

Definitions
Discount. Money off the sticker price. On this page, $3,000 off a $35,000 car, for example. A discount is real on a specific car, not a promise on every car.
Sales tax. A percentage of the price. On this page, 7%: $2,450 at full price and $2,240 with the discount, so 7% of a $3,000 discount is $210 less tax.
Loan interest. The fee the lender charges for borrowing the money. On this page, 60 months at 6.5% costs $5,802 at full price and $5,243 with the discount, $559 less because the loan is smaller.
Depreciation. The price minus the resale value. On this page, the $35,000 price minus the $16,800 resale value is $18,200, and the $32,000 price minus the same $16,800 is $15,200.
Resale value. What the car is worth at the end. On this page, $16,800 in both runs, held the same so the discount comes straight off depreciation.
Out-the-door total. Price plus tax plus fees, not the monthly payment and not the discount headline. On this page, $38,350 at full price and $35,140 with the discount.
Incentives. The share of the average price buyers paid that came back as manufacturer help. In December 2025, 7.5% of the average price paid, the highest point of the year, and 18% on electric cars, a record.
Questions people actually ask
What is a year-end discount really worth over five years?
On the example on this page, a $3,000 discount on a $35,000 car is worth $3,769 over five years: $3,000 off the price, $210 less sales tax at 7%, and $559 less loan interest on a 60-month loan at 6.5% with $5,000 down. The monthly cost falls from $884 to $821.
Why is the saving bigger than the discount?
Because the price feeds the tax and the loan. A lower price means less sales tax and a smaller loan, so less interest. The discount also comes straight off depreciation when the resale value is held the same in both runs.
Do December incentives mean December cars are cheaper?
Not on average. In December 2025, incentives ran at 7.5% of the average price paid, the highest of the year, while the average price paid hit a record $50,326. December buyers bought pricier cars, so the average rose even as incentives rose. A discount is real on a specific car, not a promise on every car.
When do year-end deals appear?
The last days of December stack the month's, the quarter's, and the year's sales targets at once, and outgoing model-year cars are the stock dealers most want moved. Selection thins as the month runs on, so the specific car you want may be gone.
How do I check a year-end quote?
Get the full out-the-door total for the same car, get a second out-the-door quote for the same year, model, and trim, and run both through the calculator to compare the five-year totals. The quote comparison matters more than the calendar.
