Updated
Buyers comparing generators options will find the Generac MDG25IF4 spec'd as a compact-class machine, running a 40hp engine and 1,800 lb operating weight.
At 40hp, the Generac MDG25IF4 sits at the lighter-duty end of the horsepower range for generators models tracked here (8% of the category's top horsepower figure). By operating weight, it comes in at 12% of the heaviest generators model in this dataset.
Priced at $24,999, the MDG25IF4 is modeled here as a 60-month $1-buyout capital lease at an estimated 8.5% APR — $528/mo, building to full ownership at term end. For financing at this level, a purchase price at this level is often financeable with minimal or no down payment for established businesses. Across the full 60-month term, total payments come to $31,697 — about $6,698 above the $24,999 cash price, which is the real cost of financing instead of paying up front.
At an estimated $528/month, this ranks #1 of 18 by estimated payment among currently priced generators models — 67% below the generators average of $1,591/mo.
On the tax side, this $24,999 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 $24,999 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

Is the Generac MDG25IF4 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 Generac MDG25IF4?
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 $24,999 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 Generac MDG25IF4 versus paying cash?
Over the full 60-month term, estimated payments total $31,697 -- about $6,698 more than the $24,999 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 Generac MDG25IF4?
Putting 10% down ($2,500 on this Generac MDG25IF4) reduces the estimated payment from $528/mo to roughly $477/mo at the same 8.5% 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 Generac MDG25IF4?
Estimated 5-year residual value is approximately 38.5% of MSRP.
