How to Calculate Lease Liability Under IFRS 16
Calculating lease liability is one of the most critical tasks in IFRS 16 implementation. Getting it right ensures accurate financial reporting, compliance with auditing standards, and proper representation of your company's financial obligations.
This comprehensive guide walks you through the exact process of calculating lease liability under IFRS 16, including which payments to include, how to determine the discount rate, and common errors to avoid. Whether you're in Singapore, Malaysia, or any IFRS-adopting jurisdiction, this guide applies to your lease accounting.
Overview: What is Lease Liability?
Lease liability under IFRS 16 is the present value of lease payments not yet paid at the commencement date. It represents the lessee's obligation to make future payments for the right to use an asset.
Key Principle: The lease liability is measured at the present value of future lease payments, discounted using the interest rate implicit in the lease or the lessee's incremental borrowing rate.
Why Present Value?
Money has time value. $10,000 today is worth more than $10,000 in 5 years because you could invest today's $10,000 and earn returns. IFRS 16 requires discounting future lease payments to reflect this time value of money.
Example: A lease with 36 monthly payments of $5,000 totals $180,000 undiscounted. But at 5% interest, the present value is only ~$169,000 - that's the true economic liability at commencement.
Step 1: Identify Lease Payments to Include
Not all payments related to a lease are included in the lease liability measurement. IFRS 16 specifies exactly which payments to include:
Payments to INCLUDE:
Fixed Payments
Regular rent payments specified in the contract, less any lease incentives receivable.
Example: $10,000/month for 36 months
Variable Payments (Index/Rate Based)
Variable payments that depend on an index or rate (e.g., CPI, market interest rate).
Example: Base rent of $10,000 + annual CPI adjustment
Note: Initially measured using the index/rate at commencement date.
Residual Value Guarantees
Amounts expected to be payable under residual value guarantees.
Example: Guarantee the equipment will be worth at least $50,000 at lease end.
Purchase Options
Exercise price of a purchase option if reasonably certain to exercise.
Example: $25,000 purchase option that's below expected fair value.
Termination Penalties
Penalties for terminating the lease, if the lease term reflects exercising termination.
Example: $100,000 penalty if terminated early.
Payments to EXCLUDE:
Variable Payments (Performance/Usage Based)
Variable payments based on performance or usage of the underlying asset.
Example: Percentage of sales rent, excess mileage fees, per-page printing charges.
Treatment: Recognized as expense when incurred.
Non-Lease Components
Payments for services or other non-lease components (unless practical expedient elected).
Example: Separately identifiable maintenance, utilities, property taxes.
Security Deposits
Refundable security deposits (these are separate assets).
Example: $50,000 refundable deposit.
Step 2: Determine the Discount Rate
The discount rate is critical - even a 1% difference can change your lease liability by 5-10%. IFRS 16 provides a clear hierarchy:
Option 1: Interest Rate Implicit in the Lease (Preferred)
The implicit rate is the rate that causes the present value of:
- Lease payments, PLUS
- Unguaranteed residual value
...to equal the sum of:
- Fair value of the underlying asset, PLUS
- Lessor's initial direct costs
Reality Check: In practice, lessees rarely have access to the lessor's initial direct costs or expected residual value, making the implicit rate difficult to determine. Most lessees use the incremental borrowing rate.
Option 2: Incremental Borrowing Rate (Most Common)
The incremental borrowing rate (IBR) is the rate the lessee would have to pay to borrow:
- Over a similar term
- With a similar security
- The funds necessary to obtain an asset of similar value
- In a similar economic environment
How to Determine Your IBR
1. Start with a Reference Rate
Singapore:
- Prime Lending Rate: 4.25% - 5.75%
- SORA (Singapore Overnight Rate Average)
- SGS (Singapore Government Securities) yield curve
Malaysia:
- Base Lending Rate (BLR): 6.40% - 6.65%
- Overnight Policy Rate (OPR): 2.75%
- MGS (Malaysian Government Securities) yields
See current reference rates on our main page.
2. Adjust for Entity-Specific Factors
Add spread for:
- Credit risk: Higher risk = higher rate (0.5% - 3%)
- Asset specificity: Specialized assets may warrant premium
- Collateral quality: Real estate vs. equipment
Example:
- Base prime rate: 5.0%
- Credit spread (BBB rated): +1.5%
- IBR = 6.5%
3. Match the Lease Term
Ensure your rate matches the lease term:
- 3-year lease → 3-year borrowing rate
- 5-year lease → 5-year borrowing rate
Use the yield curve if available to interpolate rates for non-standard terms.
4. Document Your Methodology
Critical for audits. Document:
- Reference rate source and date
- Credit spread justification
- Adjustments made
- Final IBR calculation
Auditors will scrutinize your IBR selection, so maintain detailed workpapers.
Step 3: Calculate Present Value
Once you have your payments and discount rate, calculate the present value using the appropriate formula based on payment timing.
Present Value Formulas
Ordinary Annuity (Payments at End of Period)
PV Formula (Ordinary Annuity):
PV = PMT × [(1 - (1 + r)^-n) / r]
Where:
- PMT = Periodic payment amount
- r = Periodic interest rate (annual rate / periods per year)
- n = Total number of payment periods
Annuity Due (Payments at Start of Period)
PV Formula (Annuity Due):
PV = PMT × [(1 - (1 + r)^-n) / r] × (1 + r)
Same as ordinary annuity, but multiplied by (1 + r) to account for earlier payment timing.
Worked Example
- Monthly payment: $8,000
- Lease term: 36 months
- Payment timing: Start of month (Annuity Due)
- Annual IBR: 5.0%
Step 1: Calculate periodic rate
Monthly rate (r) = 5.0% / 12 = 0.4167% = 0.004167
Step 2: Apply annuity due formula
PV = $8,000 × [(1 - (1.004167)^-36) / 0.004167] × (1.004167)
PV = $8,000 × 33.7346 × 1.004167
PV = $8,000 × 33.8751
PV = $271,001
Initial Lease Liability = $271,001
Multiple Payment Components
If your lease has multiple components (e.g., regular payments + purchase option), calculate the PV of each separately and sum them:
Example: Quarterly payments + purchase option
- PV of quarterly payments (16 quarters × RM 25,000 at 1.5%): RM 353,283
- PV of purchase option (RM 50,000 discounted 16 quarters): RM 39,401
- Total Lease Liability: RM 392,684
Step 4: Initial Recognition
At Commencement Date
Journal Entry:
Cr. Lease Liability $271,001
(To recognize lease at present value of payments)
Note: For simplicity, this example assumes ROU Asset = Lease Liability. In practice, adjust ROU asset for:
- Add: Initial direct costs incurred by lessee
- Add: Prepayments made at or before commencement
- Less: Lease incentives received
- Add: Estimated restoration costs
Step 5: Subsequent Measurement (Amortization)
After initial recognition, the lease liability is measured using the effective interest method:
Each Period:
- Calculate Interest Expense: Opening Lease Liability × Periodic Interest Rate
- Add Interest to Liability: Lease Liability increases by interest
- Reduce by Payment: Lease Liability decreases by payment made
- Closing Balance: Opening + Interest - Payment
Amortization Schedule (First 3 Months)
| Month | Opening Balance | Payment | Interest (0.4167%) | Principal | Closing Balance |
|---|---|---|---|---|---|
| 1 (Jan 2025) | $271,001 | $8,000 | $0 | $8,000 | $263,001 |
| 1 (Month-end) | $263,001 | - | $1,096 | - | $264,097 |
| 2 (Feb 2025) | $264,097 | $8,000 | - | $8,000 | $256,097 |
| 2 (Month-end) | $256,097 | - | $1,067 | - | $257,164 |
Note: For Annuity Due, the first payment is made immediately, so no interest accrues on it. Interest starts accruing on the reduced balance.
Common Calculation Errors to Avoid
Error 1: Using Annual Rate Instead of Periodic Rate
Wrong: Using 5% annual rate for monthly discounting
Correct: 5% / 12 = 0.4167% monthly rate
Impact: Can overstate liability by 40-50%
Error 2: Forgetting to Discount
Wrong: Recording total undiscounted payments
Correct: Always calculate present value
Example: 36 × $8,000 = $288,000 (wrong) vs. $271,001 PV (correct)
Error 3: Wrong Annuity Formula
Issue: Using ordinary annuity when payments are in advance
Check: Lease says "payable in advance" → Use Annuity Due
Impact: ~1-2% error in PV
Error 4: Including Non-Lease Components
Wrong: Including maintenance or utilities in lease payments
Correct: Separate lease from non-lease components
Note: Practical expedient allows combining, but must be elected
Error 5: Using Wrong IBR
Wrong: Using same rate for all leases regardless of term
Correct: Match IBR to lease term and asset risk
Tip: 3-year office lease ≠ 10-year equipment lease
Error 6: Ignoring Rent-Free Periods
Wrong: Starting payment count from Month 3 in a 36-month lease with 2 rent-free months
Correct: Discount back the PV to commencement date
