Under IFRS 16 and ASC 842, lessees recognize a right-of-use asset and lease liability for most leases. Select your reporting standard, then build the lease liability amortization schedule for planning and controller review. This tool models liability amortization only — not full standard compliance.
How to use this calculator
- Select IFRS 16 or ASC 842 as your reporting framework.
- Enter the contractual lease payment amount and frequency.
- Set the lease term in years and the incremental borrowing / discount rate.
- Enter the initial lease liability (present value of lease payments at commencement).
- Select whether payments occur at the beginning or end of each period.
- Review present value reconciliation, the amortization table, and financing cost metrics.
Formula
Present value of payments uses the periodic discount rate: PV = Payment × [(1 − (1 + r)^−n) / r], adjusted for beginning-of-period (annuity due) timing. Each period: interest expense = opening liability × periodic rate; principal reduction = payment − interest; ending liability = opening − principal. Liability amortization mechanics are similar under IFRS 16 and ASC 842; presentation and policy elections differ.
Example
A $120,000 initial liability with $2,500 monthly payments, 5% discount rate, and 5-year term generates declining interest expense each period as the liability amortizes toward zero.
Frequently asked questions
What is the difference between IFRS 16 and ASC 842?
Both require recognition of lease assets and liabilities for most leases. Presentation, exemptions, and transition details differ — consult your reporting framework and auditor for policy elections.
What discount rate should I use?
Use the rate implicit in the lease if readily determinable; otherwise the lessee's incremental borrowing rate (IBR) at commencement. This calculator accepts your annual rate input.
How does payment timing affect the schedule?
Beginning-of-period payments reduce liability before interest accrues on the remaining balance, producing a different interest pattern than end-of-period (ordinary annuity) payments.
Does this replace lease accounting software?
No. This is a planning and education tool for lease liability amortization. ROU asset depreciation, classification, remeasurement, modification, and disclosure require professional systems and judgment.
Should I select IFRS 16 or ASC 842?
Choose the framework that applies to your entity's financial reporting. Liability amortization math is similar; policy elections, presentation, and disclosure differ.
