Incremental Borrowing Rate (IBR) Calculator for Lease Accounting

Under lease accounting standards like IFRS 16 and ASC 842, a lessee must recognize a lease liability and a right-of-use asset. The lease liability is initially measured at the present value of lease payments, discounted using the interest rate implicit in the lease. If that rate cannot be readily determined, the lessee must use its Incremental Borrowing Rate (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 similar security, the funds necessary to obtain an asset of a similar value to the right-of-use asset in a similar economic environment. This calculator uses the common "build-up approach" to estimate the IBR by starting with a risk-free rate and adding specific risk premiums.

Reference rate for a similar term (e.g., government bond yield).
Adjustment based on the lessee's creditworthiness.
Adjustment for the quality and liquidity of the underlying asset as collateral.
Other adjustments specific to the lease agreement or economic environment.

Understanding the Build-Up Approach Components

The build-up approach is a practical method for determining the IBR when direct observable market data is not available. Here's a breakdown of each component used in our calculator:

  • Base Risk-Free Rate: This is the starting point. It should reflect the risk-free rate for a currency and term that matches the lease payments. Often, the yield on government bonds with a similar maturity to the lease term is used as a proxy.
  • Lessee Credit Spread: This represents the premium a lender would charge based on the lessee's specific credit risk. A company with a lower credit rating will have a higher credit spread. This can often be derived from the yields on the lessee's existing traded debt or from market data for companies with similar credit profiles.
  • Asset-Specific Adjustment: The IBR is a secured rate. The nature of the underlying leased asset (the collateral) affects the rate. Highly liquid and valuable assets might reduce the rate (a negative adjustment), while specialized or rapidly depreciating assets might not provide as much security.
  • Lease Term / Other Adjustments: This catches other factors. For example, the payment profile (e.g., payments in advance vs. in arrears) can impact the rate. It also accounts for any differences between the terms of the reference data used and the specific lease contract.

Example Calculation

Consider a company entering into a 5-year lease for a piece of standard machinery. The company has a 'BBB' credit rating.

  • Base Risk-Free Rate: The 5-year government bond yield is currently 2.50%.
  • Lessee Credit Spread: Market data indicates a credit spread of 3.00% for BBB-rated companies for a 5-year term.
  • Asset-Specific Adjustment: The machinery is standard and has good resale value, providing strong collateral. An adjustment of -0.50% is applied to reflect this security.
  • Other Adjustments: The lease requires payments at the start of each period, which slightly reduces risk for the lessor. A small adjustment of -0.10% is made.

Using the calculator, the estimated IBR would be:

2.50% + 3.00% – 0.50% – 0.10% = 4.90%

This 4.90% is the rate the company would use to discount its future lease payments to determine the initial value of the lease liability and right-of-use asset.
