This playbook gives FP&A and accounting teams a practical approach to model the IFRS 16 impact on EBITDA. It covers model structure, critical input drivers, transition choices, pro‑forma adjustments, sensitivity testing, and reconciling forecasts to statutory accounts.
IFRS 16 shifts most lease expense from operating expense into depreciation and interest. That change increases EBITDA presentation without changing underlying cash flows. For budgeting and forecasting, that matters because EBITDA-based targets, covenants and management KPIs will move even though economic performance has not.
Finance leaders need models that reproduce accounting mechanics and remain usable for decision-making. This guide is for FP&A and accounting teams who must build transparent, auditable models and align management reporting with statutory numbers. There is no one-size-fits-all model, but the playbook below provides a repeatable structure and practical controls.
IFRS 16 removes most operating lease expense from operating profit and replaces it with right-of-use (ROU) depreciation and interest on the lease liability. Depreciation is recorded within operating profit, while interest sits below operating profit. As a result, EBITDA increases relative to pre‑IFRS 16 presentation because an expense that used to reduce operating profit is now largely shown as depreciation.
This EBITDA uplift is a presentation effect, not an increase in cash generation. Total expense over the lease term remains equal, though timing changes because interest declines over the lease life while depreciation is usually straight‑lined. Common misinterpretations include treating higher EBITDA as higher free cash flow or as a permanent efficiency gain. Both are incorrect without additional analysis of cash flows and financing structure.

Build the model in layers so each purpose is clear and auditable. At minimum, separate these sheets or modules: a contract register, cash flow schedules, accounting schedules, and management P&L/pro‑forma lines.
The contract register stores source data and identifiers. Cash flow schedules convert contract terms into payment timelines. Accounting schedules compute the ROU asset, lease liability, depreciation and interest using IFRS 16 rules. The management P&L maps statutory lines into pro‑forma operating expense and EBITDA for budgeting and KPIs.
Keep accounting calculations untouched and link them to a pro‑forma bridge. That separation makes it easy to reconcile and to show management-friendly metrics without altering statutory math. Use a controlled file architecture: read‑only accounting module, a linked FP&A module for scenarios, and a versioned assumptions sheet. Enforce version control and clear naming conventions for each forecast cut.

A small number of inputs drive most of the IFRS 16 impact on ebitda. Treat these as governance items with owners and version history.
Lease commencement and end dates. These determine the pattern of depreciation and interest. Small date shifts change comparatives and expiry cliffs.
Lease payments, payment frequency and CPI or fixed increases. Increases change nominal cash flows and the ROU measurement at each remeasurement.
Renewal, termination options and probability assumptions. Estimated lease term drives the length of depreciation and the amortisation profile.
Discount rate (incremental borrowing rate) and its derivation. Discount rate affects lease liability present value and interest expense.
Variable payments and practical expedients. Decide whether low‑value and short‑term lease exemptions apply and how to forecast variable leases.
Align accounting and FP&A on inputs where legal facts exist, and document judgment areas such as renewal probabilities or the choice of incremental borrowing rate.
The two common transition methods (full retrospective and modified retrospective) have different implications for comparative periods and budgeting. Full retrospective restates prior periods and produces directly comparable historical EBITDA. Modified retrospective adjusts opening balances and requires disclosure of adjustments to comparatives.
For FP&A, maintain a pro‑forma bridge showing: statutory reported EBITDA, IFRS 16 adjustment, and management EBITDA. Keep a reconciliation tab that links each pro‑forma line back to accounting schedules and the contract register. Document every assumption used for pro‑forma adjustments and retain signed approval for material judgement calls. That creates an audit trail and helps auditors and management trace numbers back to source.
Set up sensitivity runs that isolate high‑impact drivers. Use scenario matrices to show the effect on EBITDA and on interest and depreciation lines separately. Recommended scenarios include consistent discount rate changes, CPI shocks, and shifts in renewal probability.
Include these scenario types:
Base, upside and downside scenarios using the same discount-rate derivation.
One‑off portfolio events such as a large renegotiation or termination.
Stress tests for expiry cliffs and concentration risk.
When presenting results, show both the EBITDA movement and the cash‑flow and balance‑sheet consequences. Avoid over-interpreting small EBITDA changes without checking the related interest and depreciation offsets. Watch for double‑counting when scenarios combine multiple drivers.
Make reconciliation a routine deliverable. Produce a simple schedule that maps management EBITDA to statutory depreciation and interest by contract group and period. Highlight timing differences and one‑off items so reviewers can see why management and statutory numbers differ.
Operational collaboration prevents surprises. Agree on a monthly data refresh from accounting, a single source of truth for lease amendments, and a governance cadence for assumption changes. Maintain versioned assumptions, a one‑line change log for material updates, and defined sign‑off roles for accounting and FP&A. This keeps forecasts auditable and reduces reconciliation work at month end.

An effective IFRS 16 EBITDA model balances accounting precision with FP&A usability. Start with a layered, auditable structure, align on key inputs, document transition choices and build a small set of scenarios. Clear reconciliation routines and disciplined collaboration between accounting and finance make the model reliable for budgeting, forecasting and executive reporting.
