Understanding the 90% Lease Rule: A Comprehensive Guide

In the realm of accounting and financial reporting, the distinction between finance leases and operating leases is critical. This classification affects how leases are represented on the balance sheet and income statement, influencing key financial ratios and metrics. Among the criteria used to differentiate these lease types, the 90% lease rule plays a pivotal role.

The Essence of the 90% Lease Rule

Key Components

Minimum Lease Payments

Minimum lease payments are the non-cancelable payments that the lessee is obliged to make under the lease agreement. These payments exclude contingent rents, costs for services, and taxes to be paid by and reimbursed to the lessor.

Present Value (PV)

The present value calculation discounts the future stream of minimum lease payments to their value in today’s dollars, incorporating the time value of money.

Fair Value

Fair value refers to the estimated market value of the leased asset at the commencement of the lease.

Application of the Rule

The 90% lease rule states that a lease should be classified as a finance lease if the present value of the minimum lease payments amounts to at least 90% of the fair value of the leased asset. This assessment suggests that the lease is more akin to a purchase of the asset with financing, thus necessitating finance lease accounting.

Additional Criteria for Lease Classification

While the 90% rule is significant, it is part of a broader set of criteria. Other factors include:

  • Lease Term: A lease term covering a major portion of the asset’s economic life (usually 75% or more) leans towards a finance lease.
  • Bargain Purchase Option: A provision allowing the lessee to purchase the asset at a price significantly below its expected market value at the end of the lease term indicates a finance lease.
  • Transfer of Ownership: A lease that specifies the transfer of ownership of the asset to the lessee by the end of the lease term is treated as a finance lease.
  • Specialized Asset: If the leased asset is so specialized that it is only usable by the lessee without major modifications, it suggests a finance lease.

Navigating Lease Classification with the 90% Rule

The Importance of Accurate Classification

Accurate lease classification is paramount for transparent financial reporting and compliance with accounting standards like ASC 842 and IFRS 16. It impacts how assets and liabilities are presented, affecting a company’s financial health portrayal.

Consulting with Professionals

Given the complexity and nuances of lease accounting, seeking advice from qualified accounting professionals is advisable. They can provide insights into the specific terms of a lease agreement and ensure compliance with relevant accounting standards.


The 90% lease rule is a crucial element in lease classification, determining how leases are accounted for and reported in financial statements. By understanding and applying this rule, along with other criteria, companies can ensure accurate financial reporting and compliance with accounting standards.
