ECL Calculator (Ind AS 109)
Compute Expected Credit Loss
Pick your approach — General for loans and debt instruments, or Simplified for trade receivables. The calculator applies the Ind AS 109 methodology and generates a journal entry plus disclosure narrative.
Asset Classification
Stage 1: No SICR — recognise 12-month ECL. Interest on gross carrying amount.
ECL Components (PD × LGD × EAD)
Outstanding gross exposure including accrued interest.
12-month PD for Stage 1 (typical 0.5-3% for investment-grade).
Expected loss as % of EAD after collateral recoveries (typical 30-60% for unsecured).
Time-value discount factor as % of nominal (e.g. 95 for 5% discount). Leave blank for no discounting.
Provision Matrix — Trade Receivables Aging
Enter outstanding receivable amounts in each aging bucket. Default rates are illustrative — derive from your historical credit loss experience adjusted for forward-looking information per Ind AS 109 Para 5.5.15.
The calculator implements both approaches permitted under Ind AS 109 Financial Instruments. Choose General Approach for loans, debt securities, loan commitments and financial guarantees; Simplified Approach for trade receivables, contract assets and lease receivables.
General Approach — Three-Stage Model
Classify the asset into Stage 1, 2 or 3 based on credit risk evolution since initial recognition. Apply the standard ECL formula to compute the loss allowance. The PD horizon depends on stage — 12-month PD for Stage 1, lifetime PD for Stages 2 and 3.
ECL = PD × LGD × EAD
PD Probability of Default (12-month or lifetime)
LGD Loss Given Default (% of EAD after recoveries)
EAD Exposure At Default (gross outstanding amount)
Simplified Approach — Provision Matrix
For trade receivables and similar financial assets, Ind AS 109 Para 5.5.15 permits the practical expedient of a provision matrix. Receivables are grouped into aging buckets, each with a historical loss rate adjusted for current and forward-looking conditions. Bucket-wise ECL is summed for total lifetime ECL.
Lifetime ECL = Σ (Bucket Amount × Bucket Default Rate %)
Coverage Ratio = Total ECL ÷ Total Receivables × 100
Stage Classification Drivers
Stage 1 (Performing): No significant increase in credit risk since initial recognition. 12-month ECL recognised. Interest on gross carrying amount.
Stage 2 (Underperforming): Significant Increase in Credit Risk (SICR). Lifetime ECL recognised. Rebuttable presumption: 30 days past due. Interest on gross.
Stage 3 (Credit-Impaired): Default has occurred. Lifetime ECL recognised. Rebuttable presumption: 90 days past due. Interest on net carrying amount (gross − ECL).
Forward-Looking Information
Ind AS 109 mandates forward-looking ECL — entities must incorporate reasonable and supportable information about future economic conditions (GDP, unemployment, inflation, sector outlooks). Multiple scenarios (base, upside, downside) with assigned probabilities are typically used to compute probability-weighted ECL. This is a fundamental shift from the Ind AS 39 incurred loss model and significantly increases ECL provisions for early-stage assets.

Backwards transition: An asset can move from Stage 3 back to Stage 1 if credit risk improves significantly and remains improved for a probationary period. RBI's discussion paper on ECL for banks proposes a minimum 6-month probationary period in Stage 3 even after irregularities are corrected, before reclassification to Stage 1.

Deriving Your Own Rates
Collect historical data: Track invoice-level payment behaviour over at least 3-5 years
Compute roll-rates: What % of receivables in bucket N moved to bucket N+1 vs got collected?
Calculate cumulative loss: For each starting bucket, compute eventual write-off as % of original
Segment by customer profile: B2C vs B2B, geography, product line, customer rating — apply separately if loss patterns differ
Adjust for forward-looking: Apply scalar adjustments for current macroeconomic outlook (GDP, sector stress, interest rate cycle)
Document methodology: Working paper showing data sources, methodology, key judgements and probability weights
Audit defence tip: Auditors and NFRA inspections frequently challenge provision matrix rates as too low or unsupported by data. Maintain a clear back-up showing historical loss rates, the adjustment factor for forward-looking information, and sensitivity analysis (impact of ±20% movement in default rates on ECL).

Expected Credit Loss (ECL) under Ind AS 109 Financial Instruments is the probability-weighted estimate of credit losses on financial assets, recognised on a forward-looking basis. Effective for Ind AS companies from 1 April 2018, it replaces the incurred loss model under Ind AS 39 and AS 30. ECL must reflect an unbiased probability-weighted amount, the time value of money, and reasonable and supportable information including past events, current conditions and forward-looking forecasts.
Stage 1 covers performing financial assets where credit risk has not significantly increased since initial recognition — 12-month ECL is recognised. Stage 2 covers underperforming assets where credit risk has significantly increased (SICR) — lifetime ECL is recognised. Stage 3 covers credit-impaired assets where default has occurred — lifetime ECL is recognised, and interest revenue is calculated on the net carrying amount (gross less ECL allowance), unlike Stages 1 and 2 which use gross.
SICR is the trigger for moving an asset from Stage 1 to Stage 2 under Ind AS 109. The standard provides a rebuttable presumption that SICR has occurred when contractual payments are more than 30 days past due. Other indicators include credit rating downgrade, adverse change in business or economic conditions, expected forbearance, and significant changes in external market indicators of credit risk. SICR assessment is forward-looking, considering reasonable and supportable information.
Probability of Default (PD) is the likelihood a borrower defaults within a given time horizon — 12-month PD for Stage 1, lifetime PD for Stages 2 and 3. Loss Given Default (LGD) is the expected loss as a percentage of EAD after collateral recoveries. Exposure at Default (EAD) is the gross outstanding exposure at default. The standard formula is ECL = PD × LGD × EAD, optionally discounted at the original effective interest rate.
General Approach applies the three-stage model to financial assets at amortised cost or FVOCI — loans, debt securities, loan commitments, financial guarantees. The entity must track SICR and stage transitions over time. Simplified Approach is permitted for trade receivables, contract assets and lease receivables — entities recognise lifetime ECL from initial recognition without tracking SICR. The simplified approach typically uses a provision matrix based on aging buckets and historical loss rates.
A provision matrix is the practical expedient under Ind AS 109 Para 5.5.15 for computing lifetime ECL on trade receivables. The matrix specifies provision rates by past-due aging bucket (e.g., 0.5% current, 2% 1-30 days, 5% 31-60 days, 30% 91-180 days, 100% above 365 days). Rates are derived from historical credit loss experience adjusted for current conditions and forward-looking forecasts. Customer segmentation by region, rating or product type may be applied where loss patterns differ.
Ind AS 109 requires ECL to incorporate reasonable and supportable forward-looking information about future economic conditions — GDP growth, unemployment, inflation, interest rates, sector-specific outlooks. This is a fundamental shift from Ind AS 39 incurred loss model. Entities typically build multiple economic scenarios (base, upside, downside) with assigned probabilities, then compute probability-weighted ECL. Information must be available without undue cost or effort and must be applied consistently across reporting periods.
Ind AS 109 defines a credit-impaired asset as one where one or more events have occurred that have a detrimental impact on estimated future cash flows. Indicators include significant financial difficulty of the issuer, breach of contract such as a default or past due event, lender granting a concession not otherwise considered, probability of bankruptcy, and disappearance of an active market. The standard sets a rebuttable presumption that default occurs no later than 90 days past due.
Ind AS 39 used an incurred loss model — credit losses recognised only after objective evidence of impairment existed. Ind AS 109 uses an Expected Credit Loss model — losses recognised on a forward-looking basis from initial recognition. The change brings forward loss recognition, increases provisions in early-stage assets, and requires sophisticated PD/LGD modelling. Total expected losses over a portfolio's lifetime are typically larger and earlier under Ind AS 109, particularly for banks, NBFCs and large corporates.
Initial application of Ind AS 109 typically increased loss allowances substantially compared to Ind AS 39 — banks, NBFCs and lenders saw the largest impact. ECL is recognised in P&L as an impairment loss, with the loss allowance reducing the carrying amount of the financial asset. Each subsequent reporting date requires remeasurement with movements taken to P&L. For FVOCI debt instruments, ECL is recognised in P&L but the allowance does not reduce balance sheet carrying amount.
Ind AS 107 Financial Instruments Disclosures requires entities to disclose the credit risk management practices, ECL measurement methodology including key inputs and assumptions, reconciliation of opening to closing loss allowance with movements between stages, gross carrying amount and loss allowance by stage and credit grade, modification of contractual cash flows, write-off policy, and concentration of credit risk. Forward-looking information assumptions and sensitivity analysis are typically included for material portfolios.
Indian Ind AS-compliant NBFCs apply Ind AS 109 ECL framework directly. Scheduled commercial banks currently follow RBI's Income Recognition Asset Classification and Provisioning (IRACP) norms — RBI issued a discussion paper in January 2023 proposing transition to ECL framework with regulatory backstops, prudential floor and special treatment for Stage 3 interest accrual. Co-operative banks may receive separate thresholds. Final RBI guidelines will determine the transition timeline for the banking sector.
Yes, in principle. Cash deposits with banks are financial assets subject to ECL under Ind AS 109. However, for high-credit-quality banks (typically AA-rated and above scheduled commercial banks), the ECL is usually negligible due to very low PD and high recovery expectations. Many entities apply a low credit risk practical expedient under Ind AS 109 Para 5.5.10 — assets continue at 12-month ECL even without explicit SICR assessment. Material exposures to weak banks require explicit ECL computation.
