Effective interest rate in IFRS 9

Last Updated on 23/02/2020 by 75385885

Effective interest rate

The rate that exactly discounts estimated future cash payments or receipts through the expected life of the financial asset or financial liability to the gross carrying amount of a financial asset or to the amortised cost of a financial liability.

When calculating the effective interest rate, an entity shall estimate the expected cash flows by considering all the contractual terms of the financial instrument (for example, prepayment, extension, call and similar options) but shall not consider the expected credit losses.

The calculation includes all fees and points paid or received between parties to the contract that are an integral part of the effective interest rate (see IFRS 9 paragraphs B 5.4.1–B 5.4.3), transaction costs, and all other premiums or discounts. There is a presumption that the cash flows and the expected life of a group of similar financial instruments can be estimated reliably.

However, in those rare cases when it is not possible to reliably estimate the cash flows or the expected life of a financial instrument (or group of financial instruments), the entity shall use the contractual cash flows over the full contractual term of the financial instrument (or group of financial instruments).


Calculation examples:

The loan is CU 50,000, monthly payment CU 1,250, loan period 5 years. The add-on interest rate ([total monthly payments / loan amount) – 1] / loan period x 100%) is 10%.

What is the effective interest rate?

The spreadsheet way

Discount 60 monthly terms (5 years of 12 months) of CU 1,250 and an initial loan of 50,000 against an interest rate estimation (CELL B2 below) until the discounted value is equal or very close to CU 0 (CELL C7). The answer is 17.2737% per annum.

The XIRR Function way

Or use the XIRR function on this table.

=XIRR(values, dates, [guess])

This function returns the internal rate of return for a schedule of cash flows that is not necessarily periodic.

The XIRR function syntax has the following data input:

  • Values – requires a range of data source. This is a series of cash flows that corresponds to a schedule of payments in dates. The first payment is optional and corresponds to a cost or payment that occurs at the beginning of the investment. If the first value is a cost or payment, it must be a negative value. The series of values must contain at least one positive and one negative value.
  • Dates – requires a range of specific date of cash flows (in- and outflows). This is a schedule of payment dates that corresponds to the cash flow payments. Dates may occur in any order.
  • Guess – is an option to enter a reference to a cell where to enter a percentage that is estimated to be close to the result of XIRR.

This looks as follows:

Effective interest rate

Note: Although the numbers are the same the outcome is a slightly higher EIR, this results from the fact that the XIRR function uses actual interest days and the the first spreadsheet calculation used a simple approach to adjust the annual rate estimate entered in the model is calculated by dividing it in 12 equal parts (no compound interest calculation used).

Amortised cost annual movements

This results in the following movement schedule

Effective interest rate

Note: Just as a check the total Interest PNL charge (25,000) and Repayments (-75,000) in the above movements is used as a control number, seen the first excel picture above that also ends with the same amounts as Effective interest in total for 60 months (25,000) and repayment in total for 60 months (-75,000).

Fees that are (not) an integral part of the EIR

IFRS 9 incorporates the guidance on financial service fees (both received and paid) that are an integral part of the EIR of a financial instrument. IFRS 9 also includes examples of fees that are not an integral part of the EIR, which are accounted for under IFRS 15. (IFRS 9.B5.4.1–3)

Food for thought – Fees that are an integral part of the EIR

  • Origination fees received by the entity relating to the creation or acquisition of a financial asset. Such fees may include compensation for activities such as evaluating the borrower’s financial condition, evaluating and recording guarantees, collateral and other security arrangements, negotiating the terms of the instrument, preparing and processing documents and closing the transaction. These fees are an integral part of generating an involvement with the resulting financial instrument.
  • Commitment fees received by the entity to originate a loan when the loan commitment is not measured in accordance with IFRS 9.4.2.1(a) and it is probable that the entity will enter into a specific lending arrangement. These fees are regarded as compensation for an ongoing involvement with the acquisition of a financial instrument. If the commitment expires without the entity making the loan, the fee is recognised as revenue on expiry.
  • Origination fees paid on issuing financial liabilities measured at amortised cost. These fees are an integral part of generating an involvement with a financial liability. An entity distinguishes fees and costs that are an integral part of the effective interest rate for the financial liability from origination fees and transaction costs relating to the right to provide services, such as investment management services.

Food for thought – Fees that are not an integral part of the EIR

  • Fees charged for servicing a loan;
  • Commitment fees to originate a loan when the loan commitment is not measured in accordance with IFRS 9.4.2.1(a) and it is unlikely that a specific lending arrangement will be entered into; and
  • Loan syndication fees received by an entity that arranges a loan and retains no part of the loan package for itself (or retains a part at the same effective interest rate for comparable risk as other participants).

In the spreadsheet this looks like (added 250 transaction costs on 01/01/2021):

And the EIR increases from 18.7371% to 19.0101%.
