Updated Cross-checked against 1 government/public rate source
With a 121hp engine and 49,600 lb operating weight, the Caterpillar 320 GC sits at the mid-size end of the crawler excavators lineup.
Compared against every other crawler excavators page on this site, the Caterpillar 320 GC's 121hp puts it at the lighter-duty end of the horsepower range for crawler excavators models tracked here. By operating weight, it comes in at 22% of the heaviest crawler excavators model in this dataset.
The numbers below assume a 60-month $1-buyout capital lease on the $185,000 320 GC: $3,789/mo at an estimated 8.25% 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 $227,316 — about $42,316 above the $185,000 cash price, which is the real cost of financing instead of paying up front.
At an estimated $3,789/month, this ties for #9 of 42 by estimated payment (tied with 1 other currently priced crawler excavators model at this exact price point) — 26% below the crawler excavators average of $5,141/mo.
On the tax side, this $185,000 purchase is Section 179-eligible under the 2026 cap of $2,560,000, and 100% bonus depreciation -- back in effect for equipment placed in service after January 19, 2025 -- means a qualifying buyer could potentially deduct the entire $185,000 in the year it's placed in service rather than depreciating it over several years, subject to the buyer's own taxable income and CPA sign-off.

Frequently Asked Questions
What is the estimated monthly payment for a financed Caterpillar 320 GC?
An estimated $3788.60/month over 60 months at a base APR of 8.25%, 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 8.25% base APR: Subprime 12.75%, Fair 10.75%, Good 8.25%, Very Good 7.50%, Prime 6.75%. "Good" is the default tier shown; drag the slider to see the exact payment at your tier.
Is the Caterpillar 320 GC 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 Caterpillar 320 GC?
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 $185,000 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 Caterpillar 320 GC versus paying cash?
Over the full 60-month term, estimated payments total $227,316 -- about $42,316 more than the $185,000 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 Caterpillar 320 GC?
Putting 10% down ($18,500 on this Caterpillar 320 GC) reduces the estimated payment from $3,789/mo to roughly $3,411/mo at the same 8.25% 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 Caterpillar 320 GC?
Resale value data is not yet available for this specific model.
What does a Caterpillar 320 GC rent for?
New York State DOT equipment rental rate schedule (FEMA) lists a current rental rate of $107.93/hour for this machine — a real published rate, not our own estimate.
