Understanding the IFRS 16 Discount Rate and Lease Liability

IFRS 16 changed the landscape of lease accounting, requiring lessees to recognize nearly all leases on the balance sheet. The core of this requirement is calculating the Lease Liability, which is the present value of future lease payments. The critical factor in determining this present value is the IFRS 16 discount rate.

What is the IFRS 16 Discount Rate?

The discount rate is used to convert future lease payments into a single present value figure at the commencement date of the lease. This present value becomes the initial recognition amount for the lease liability and is a key component in calculating the Right-of-Use (ROU) asset.

According to IFRS 16, the discount rate should be determined in the following hierarchy:

  1. Interest Rate Implicit in the Lease: This is the rate that causes the present value of the lease payments and the unguaranteed residual value to equal the sum of the fair value of the underlying asset and any initial direct costs of the lessor. While preferred, this rate is often difficult for lessees to determine as it requires knowledge of the lessor's costs and residual value assumptions.
  2. Lessee's Incremental Borrowing Rate (IBR): If the implicit rate cannot be readily determined, the lessee must use their IBR. The IBR is defined as the rate of interest that a lessee would have to pay to borrow over a similar term, and with a similar security, the funds necessary to obtain an asset of a similar value to the right-of-use asset in a similar economic environment.

Impact of the Discount Rate on Financial Statements

The chosen discount rate significantly affects the balance sheet and income statement:

  • A higher discount rate results in a lower initial lease liability and ROU asset. This leads to lower depreciation expenses but higher interest expenses in the early years of the lease.
  • A lower discount rate results in a higher initial lease liability and ROU asset. This increases depreciation expenses and decreases interest expenses.

How This Calculator Works

This calculator determines the initial lease liability by calculating the Present Value (PV) of your projected lease payments using the discount rate you provide (typically your estimated IBR). It handles the complexities of payment frequency and timing.

Example Calculation

Imagine a company enters a 5-year lease for office equipment. The terms are:

  • Total Annual Payment: 24,000 (paid monthly, so 2,000 per month)
  • Lease Term: 5 Years
  • Payment Timing: End of Period (Arrears)
  • Determine Discount Rate (IBR): The company determines its incremental borrowing rate for a 5-year secured loan is 4.5%.

Using these inputs in the calculator above, the total undiscounted payments over the 5 years would be 120,000. However, because of the time value of money represented by the 4.5% discount rate, the initial Lease Liability (Present Value) recognized on the balance sheet would be approximately 107,392.48.
