Updated
With a 455hp engine and 53,200 lb operating weight, the Kenworth T680 sits at the high-output end of the day cab tractors lineup.
Compared against every other day cab tractors page on this site, the Kenworth T680's 455hp puts it in the upper half of the horsepower range for day cab tractors models tracked here. By operating weight, it comes in at 67% of the heaviest day cab tractors model in this dataset.
The numbers below assume a 60-month $1-buyout capital lease on the $149,500 T680: $3,047/mo at an estimated 8% APR, ending in full ownership rather than a residual payoff. For financing at this level, lenders generally price this range on a sliding scale tied to time in business and credit profile rather than a flat rate. Across the full 60-month term, total payments come to $182,792 — about $33,292 above the $149,500 cash price, which is the real cost of financing instead of paying up front.
At an estimated $3,047/month, this ranks #10 of 12 by estimated payment among currently priced day cab tractors models — 5% above the day cab tractors average of $2,902/mo.
Because 100% bonus depreciation is currently in effect (equipment placed in service after January 19, 2025) and this asset qualifies under Section 179's $2,560,000 2026 cap, the full $149,500 cost is a candidate for a first-year deduction rather than a multi-year depreciation schedule -- the actual benefit depends on the buyer's taxable income, so this isn't a substitute for a CPA's sign-off.

Frequently Asked Questions
What is the estimated monthly payment for a financed Kenworth T680?
An estimated $3046.53/month over 60 months at a base APR of 8%, including a $750.00 doc/origination fee.
Does the estimated payment change based on credit score?
Yes. The calculator above has 5 credit tiers, each adjusting this machine's 8% base APR: Subprime 12.50%, Fair 10.50%, Good 8.00%, Very Good 7.25%, Prime 6.50%. "Good" is the default tier shown; drag the slider to see the exact payment at your tier.
Is the Kenworth T680 eligible for a Section 179 tax deduction?
Yes. Under the 2026 Section 179 cap of $2,560,000, qualifying businesses may be able to deduct the full purchase price in the year it's placed in service, subject to CPA verification.
Does 100% bonus depreciation apply to a financed Kenworth T680?
Bonus depreciation was restored to 100% for equipment placed in service after January 19, 2025, and it applies more broadly than Section 179 -- it isn't capped by the $2,560,000 Section 179 limit and generally isn't affected by a business's Section 179-eligible income limit. Financing rather than paying cash doesn't disqualify a purchase from this: the full $149,500 placed-in-service cost is typically what counts, not the amount actually paid that year. Confirm applicability with a CPA before filing.
What's the total cost of financing this Kenworth T680 versus paying cash?
Over the full 60-month term, estimated payments total $182,792 -- about $33,292 more than the $149,500 cash price. That difference is the estimated cost of financing (interest plus the $750.00 doc fee) rather than paying up front.
How much would a down payment lower the monthly payment on this Kenworth T680?
Putting 10% down ($14,950 on this Kenworth T680) reduces the estimated payment from $3,047/mo to roughly $2,743/mo at the same 8% estimated APR -- a real reduction, since a down payment lowers the amount actually financed rather than just the sticker price.
What is the typical resale or auction value for a Kenworth T680?
Estimated 5-year residual value is approximately 38.5% of MSRP.
