A bargain purchase option is a clause in a lease agreement that gives you, as the lessee, the right to buy the leased asset at the end of the lease term for significantly less than its expected fair market value. The purchase price is set low enough that exercising the option is almost certain when the lease matures. That certainty is what triggers a specific accounting treatment.
Think of it like signing a lease today with a locked-in purchase price that will look like a steal by the time the lease expires.
For a provision to qualify as a bargain purchase option, the exercise price must be sufficiently below the asset's expected fair market value at the option date. If the gap is narrow, a lessee might or might not exercise the option, and the provision would not qualify. If the price is dramatically lower, exercising becomes a near-certainty, and accounting standards require you to treat it as a bargain purchase option.
Example: a manufacturer leases equipment for 7 years with an option to buy it for $20,000 at the end. At that point, the equipment is expected to be worth $80,000. The $60,000 gap makes exercising the option economically obvious. That qualifies as a bargain purchase option.
Under both U.S. Generally Accepted Accounting Principles (ASC 842) and International Financial Reporting Standards (IFRS 16), a lease containing a bargain purchase option that you are reasonably certain to exercise must be classified as a finance lease. This changes your balance sheet substantially.
An operating lease, by contrast, simply records lease payments as an operating expense. The finance lease treatment results in higher reported expenses in the earlier years of the lease because depreciation and interest run concurrently.
Not every purchase option is a bargain. A lease might give you the right to buy equipment at fair market value at the end of the term. That is a standard purchase option, not a bargain purchase option, because there is no financial incentive built in. A bargain purchase option specifically requires the purchase price to be well below the expected fair value.
Some leases use a $1.00 purchase option at the end of the term, which is always a bargain purchase option. The $1.00 price relative to any commercially valuable asset is self-evidently below fair market value, and exercising it is guaranteed.
Companies use bargain purchase options when they want to use an asset for its productive life but prefer to defer the purchase cost. A leasing structure with a bargain purchase option effectively converts what looks like a rental agreement into a financed acquisition.
It preserves upfront capital, locks in a future purchase price today, and gives you full use of the asset throughout the lease. The trade-off is the accounting complexity and the balance sheet impact of recognizing a finance lease obligation from day one.
