IFRS 16, released in 2016 and effective January 1, 2019, replaced IAS 17 and several other standards to fundamentally change how companies account for leases. The standard’s stated goal is to “provide relevant information in a manner that faithfully represents those transactions.” In practice, this means bringing lease obligations onto the balance sheet so stakeholders can accurately assess how leases affect a company’s financial position.The most significant change introduced by IFRS 16 is the requirement for lessees to recognize a right-of-use (ROU) asset and corresponding lease liability for virtually all leases. Previously, operating leases remained off-balance-sheet, obscuring the true extent of lease commitments. Under the new framework, only short-term and low-value leases are exempt from recognition.Calculating ROU assets and lease liabilities correctly is critical for compliance under both IFRS 16 and ASC 842. This guide walks through what these assets represent, how to calculate them, and what to look out for when quantifying them under different accounting standards.What is a right-of-use asset?A right-of-use asset represents a lessee’s right to use a leased asset over the lease term. Instead of recording ownership of the physical asset, accounting standards now require companies to recognize the value of their right to use that asset.Under modern lease accounting standards (IFRS 16, ASC 842, and GASB 87), the ROU asset reflects the economic benefit a company gains from using leased property, equipment, or other assets. This applies to virtually all leases—real estate, vehicles, manufacturing equipment, and technology infrastructure.The introduction of ROU assets fundamentally changed lease accounting. Previously, under IAS 17 and ASC 840, operating leases stayed off-balance-sheet, making it difficult for stakeholders to understand a company’s true lease obligations. The new standards bring transparency by requiring lessees to recognize both an ROU asset and a corresponding lease liability on the balance sheet.What is a lease liability?Before calculating the ROU asset, it’s important to understand the lease liability—the two are intrinsically connected.The lease liability represents the present value of all future lease payments that a lessee must make over the lease term. This includes:Fixed lease paymentsVariable lease payments based on an index or rateAmounts expected to be payable under residual value guaranteesExercise price of purchase options (if reasonably certain to exercise)Termination penalties (if the lease term reflects exercising a termination option)Calculate the lease liability by discounting these future payments to their present value using an appropriate discount rate. The discount rate should be:The rate implicit in the lease (if readily determinable), orThe lessee’s incremental borrowing rateThe lease liability forms the foundation for calculating the ROU asset, representing the minimum starting point for the asset’s initial measurement.Components of the ROU assetUnderstanding what’s included in an ROU asset calculation matters for accurate financial reporting. The ROU asset comprises several components beyond just the lease liability:1. Initial lease liabilityThe present value of future lease payments serves as the foundation of the ROU asset calculation. This is always the starting point.2. Lease payments made at or before commencementAny payments made to the lessor before or at the lease commencement date increase the ROU asset. These prepayments represent an additional investment in obtaining the right to use the asset.3. Initial direct costsInitial direct costs are incremental costs that wouldn’t have been incurred if the lease hadn’t been executed. These costs are capitalized as part of the ROU asset and include:External legal fees for drafting or negotiating the lease (if success-contingent)Commissions paid to lease agents or brokersPayments to existing tenants to vacate (in real estate leases)Lease documentation and filing fees incurred after executionImportant: Costs that would have been incurred regardless of whether the lease was executed are NOT initial direct costs. This includes:Employee salaries and benefitsInternal overhead allocationsAdvertising costsLegal fees for general negotiation (before execution)4. Lease incentives receivedLease incentives reduce the ROU asset. Common incentives include:Cash payments from the lessor to the lesseeRent-free periodsTenant improvement allowancesReimbursement of relocation costsAssumption of the lessee’s pre-existing lease with a third party5. Estimated costs for asset removal or site restorationUnder IFRS 16, if the lease agreement requires the lessee to dismantle, remove, or restore the underlying asset to a specific condition, the estimated costs must be included in the ROU asset calculation. This provision applies when:The lease agreement explicitly requires restorationConstructive obligations exist based on the lessee’s past practicesLegal or regulatory requirements mandate restorationNote: ASC 842 doesn’t require inclusion of these costs in the ROU asset; instead, they’re accounted for separately under ASC 410.How to calculate a right-of-use asset under IFRS 16Let’s walk through a straightforward office lease to show how the calculation works in practice.Scenario: A company signs a 5-year office lease with these terms:Annual payment: €50,000 (paid at the start of each year)First payment made at signing: €50,000Landlord provides a cash incentive: €20,000Broker commission (initial direct cost): €5,000Estimated cost to restore office at lease end: €8,000Incremental borrowing rate: 6%Step 1: Calculate the lease liabilityThe lease liability is the present value of the remaining lease payments (4 payments of €50,000 each, since the first was already paid).Using the 6% discount rate: €173,255Step 2: Calculate the ROU assetComponentAmountLease liability€173,255Add: First payment already made€50,000Add: Broker commission€5,000Add: Estimated restoration costs (present value)€5,980Less: Lease incentive received(€20,000)Total ROU asset€214,235This €214,235 is what appears on your balance sheet as the right-of-use asset. The €173,255 lease liability also goes on the balance sheet, split between current and non-current portions.From there, you’ll depreciate the ROU asset over the 5-year lease term (€42,847 per year on a straight-line basis) and recognize interest expense on the lease liability.How to calculate a right-of-use asset under ASC 842While IFRS 16 and ASC 842 share many similarities, they differ in how they calculate and present ROU assets.Key difference: lease classificationASC 842 retains the distinction between:Operating leases (most leases)Finance leases (previously called capital leases)IFRS 16 treats all leases as finance leases (with limited exemptions).Initial measurement under ASC 842For both operating and finance leases, calculate the initial ROU asset using this formula:ROU Asset = Lease Liability + Prepaid Rent – Deferred Rent + Initial Direct Costs – Lease IncentivesKey differences from IFRS 16:No restoration costs included in ROU asset (accounted for separately under ASC 410)Prepaid and deferred rent from legacy leases must be adjustedNarrower definition of initial direct costsSubsequent measurement: where ASC 842 divergesOperating leases:Total lease expense recognized on straight-line basisROU asset amortization “plugs” the difference between straight-line expense and interestProduces a single “Lease Expense” line on the income statementFinance leases:Similar to IFRS 16Separate amortization and interest expenseResults in front-loaded expense patternROU asset amortization and depreciationOnce you’ve calculated the initial ROU asset, you need to account for how it decreases in value over the lease term through amortization or depreciation.IFRS 16 depreciation approachUnder IFRS 16, depreciate the ROU asset from the commencement date to the earlier of:The end of the useful life of the ROU asset, orThe end of the lease termGenerally, if:Ownership transfers to the lessee at lease end, ORThe lessee is reasonably certain to exercise a purchase optionThen depreciate over the useful life of the underlying asset.Otherwise, depreciate over the lease term.Applying the cost modelIn most cases, apply the cost model to measure the ROU asset after commencement. Under this approach, recognize the asset at cost, adjusted for accumulated depreciation and impairment, and any remeasurement of the lease liability. Depreciation is typically calculated on a straight-line basis, similar to owned property, plant, and equipment.Two exceptions exist where alternative measurement models may be used:If the lessee applies the fair value model under IAS 40 (Investment Property), they may apply that model to ROU assets that meet the definition of investment propertyIf the lessee applies the revaluation model under IAS 16 for a particular class of property, plant and equipment, they may elect to apply that model to ROU assets in the same classExample continuation: annual depreciationUsing the example with an ROU asset of €214,235 over a 5-year lease term (no purchase option):Annual depreciation = €214,235 ÷ 5 years = €42,847 per yearASC 842 amortization approachASC 842 takes a different approach depending on lease classification:Operating leases:The ROU asset is amortized so that the total lease expense (amortization + interest) is recognized on a straight-line basis. This means:ROU Asset Amortization = Total Lease Expense – Interest on Lease LiabilityThis results in decreasing amortization over time as interest expense declines.Finance leases:Similar to IFRS 16, the ROU asset is amortized on a straight-line basis over the shorter of:The lease term, orThe useful life of the asset (if ownership transfers or purchase option is reasonably certain)Impact on financial statementsThe amortization/depreciation flows through the income statement as:IFRS 16: Depreciation expense (separate from interest expense on lease liability)ASC 842 Finance Lease: Amortization expense (separate from interest expense)ASC 842 Operating Lease: Part of a single lease expense line itemGetting a helping hand with your lease accountingWhile the method to calculate the right-of-use asset under IFRS 16 and ASC 842 is well-defined, implementation becomes complex as the number of leases within an organization increases.Excel spreadsheets may work for a handful of leases, but there comes a point where manual calculation and management of leases stops being practical—particularly when dealing with multiple lease modifications, remeasurements, and varying discount rates across a global lease portfolio.This is where automated lease accounting software becomes necessary.
