Borrowing cost is a crucial concept in economics and financial decisions. It refers to the cost of borrowing money to finance a project, purchase, or investment.
The borrowing cost is typically measured as the interest rate or rate of return on investment that an individual or business must pay to borrow money. This cost can be a significant factor in determining whether a project or investment is viable.
A higher borrowing cost can make a project or investment less attractive, as it increases the risk of default and reduces the potential return on investment. Conversely, a lower borrowing cost can make a project or investment more attractive, as it reduces the risk of default and increases the potential return on investment.
What is Borrowing Cost?
Borrowing cost is a crucial concept in economics that refers to the interest and other costs incurred by an enterprise in connection with the borrowing of funds. This can include interest on short-term loans or long-term debts, such as the interest paid to financial institutions for a loan taken to acquire an asset.
According to the Institute of Chartered Accountants of India (ICAI), borrowing costs should be taken into consideration and include interest on short-term loans or long-term debts, discounts or premiums related to the borrowing cost, finance or ancillary costs in connection with the borrowings, and finance costs under finance lease or other similar arrangements.
For specific borrowing, the amount to be capitalized is the actual borrowing cost incurred during the period minus any income on temporary investment of borrowed funds. For example, if an enterprise invests excess money in a fixed deposit, the interest gain should be deducted from the actual borrowing cost.
In contrast, general borrowing involves a weighted average of borrowing cost, known as the capitalization rate. This rate is used to calculate the cost to be capitalized, which is the product of the capitalization rate and the amount spent on qualifying assets out of general borrowing.
Here's a breakdown of the types of borrowing costs:
It's essential to note that the amount of borrowing cost capitalized during a period should not exceed the amount of borrowing cost incurred during the period.
Types of Borrowing Costs
Borrowing costs can be categorized into several types, each with its own specific characteristics.
Interest on short-term loans or long-term debts is considered a borrowing cost. This includes interest paid to financial institutions for loans taken to acquire assets.
Discounts or premiums related to borrowing costs, such as loan processing costs, are also amortized.
Finance or ancillary costs incurred in connection with borrowings, like the cost of preparing project reports, are amortized as well.
Finance costs associated with foreign currency borrowings are amortized to the extent they are regarded as adjustments to interest costs.
Here are some examples of borrowing costs that are eligible for capitalization:
- Interest expense calculated using the effective interest method under IFRS 9
- Interest in respect of lease liabilities recognized under IFRS 16
- Exchange differences arising from foreign currency borrowings
Note that the actual or imputed cost of equity instruments is excluded from the scope of IAS 23.
Specific Borrowings
Specific borrowings are a type of borrowing cost that can be capitalized, and they're incurred specifically for obtaining a qualifying asset. This type of borrowing cost is the actual cost incurred on that borrowing during the period.
According to IAS 23.12, the borrowing costs eligible for capitalization are the actual costs incurred on that borrowing during the period. For example, on 1 March 20X1, Entity A borrowed $100,000, and on 1 June 20X1, they borrowed $300,000, and on 1 October 20X1, they borrowed $600,000.
Any investment income generated from the temporary investment of specific borrowings must be subtracted from the borrowing costs eligible for capitalization. This means that if you invest excess funds in a fixed deposit and earn interest, that interest gain will be subtracted from the borrowing costs.
Here are some specific borrowings examples:
Interest Types
Simple interest is a set rate on the principal originally lent to the borrower that the borrower has to pay for the ability to use the money.
The most common type of interest is compound interest, which is interest on both the principal and the compounding interest paid on that loan.
Individuals attempting to earn interest prefer compound interest agreements, as they result in interest being earned on interest and more total earnings.
Savings accounts with banks often earn compound interest, with any prior interest earned on your savings deposited into your account and earning interest in future periods.
Compound interest can be concerning for borrowers, especially if their accrued compound interest is capitalized into their outstanding principal, increasing their monthly payment.
Capitalization of Borrowing Costs
Capitalization of borrowing costs is a crucial concept in accounting that affects the financial statements of companies. It involves including the costs of borrowing money in the cost of an asset, rather than expensing them immediately. This means that the costs of borrowing are added to the asset's value over time, rather than being written off as an expense.
Borrowing costs can be capitalized if they are directly attributable to the acquisition, construction, or production of a qualifying asset. A qualifying asset is one that gives future benefits to the company and can be measured reliably.
The two types of borrowings that are relevant for capitalization are specific borrowings and general borrowings. Specific borrowings are those that are borrowed specifically for obtaining a qualifying asset, while general borrowings are those that are used for various purposes.
For specific borrowings, the amount to be capitalized is the actual borrowing cost incurred during the period, minus any income on temporary investments of borrowed funds. For general borrowings, the amount to be capitalized involves calculating a capitalization rate, which is the weighted average of borrowing costs.
Here's a summary of the steps to calculate the capitalization rate for general borrowings:
- Calculate the capitalization rate by dividing the interest expense by the average carrying amount of the asset during the period.
- The capitalization rate represents the weighted average of the borrowing costs applicable to the entity's outstanding borrowings during the period.
For example, if a company has $500,000 of general borrowings on January 1, and the interest expense is $50,000 for the year, the capitalization rate would be 5%. This means that the company would capitalize $20,417 of borrowing costs, calculated as ($100,000 x 10/12 + $300,000 x 7/12 + $600,000 x 3/12) x 5%.
Capitalization of borrowing costs ceases when all the activities necessary to prepare the qualifying asset are complete.
Disclosures
To be transparent with investors and stakeholders, companies must disclose certain information about their borrowing costs. The accounting policy adopted for borrowing costs is a crucial piece of information that should be disclosed.
Companies must also disclose the amount of borrowing costs capitalized during the year. This is a key metric that helps stakeholders understand the financial implications of borrowing costs on the company's bottom line.
Quantification and Calculation
Interest is calculated by multiplying the outstanding principal by the interest rate, a simple formula that's easy to grasp. The interest rate is often expressed as a percentage and is usually designated as the APR.
Calculating the APR can be tricky, as it often doesn't reflect any effects of compounding. That's why the effective annual rate is used to express the actual rate of interest to be paid.
The applicable interest rate is then multiplied against the outstanding amount of money related to the interest assessment. For loans, this is the outstanding principal balance, while for savings, it's often the average balance of savings for a given period.
Quantification in Structural Model

Using a structural open-economy model of the U.S., researchers can quantify the effects of a persistent increase in the short-term real interest rate on macro aggregates.
This model includes a cost that increases with the debt stock, capturing the idea of a default-risk premium, and capital adjustment costs to prevent exaggerating the effects of a real rate shock.
A 50 basis point increase in the short-term real interest rate, with a shock half-life of five years, can lead to a 5 percent decrease in investment on impact.
The real interest rate increase also causes consumption to fall sharply, as people respond to higher rates by deleveraging immediately.
The response to higher rates is to reduce borrowing and increase taxes, which sends money to creditors abroad and increases the current account.
In this model, the debt/GDP threshold falls as the government borrows less, but the real exchange rate remains at 1.

However, in a richer model, the positive current account response would cause an RER depreciation.
By changing the debt adjustment costs, the deleveraging can be dampened, and this is done for the impulse response functions in the figures below.
This results in a smaller decrease in the debt/GDP ratio, but also depresses economic activity in the longer term.
Formula and Calculation
Interest is calculated by multiplying the outstanding principal by the interest rate. This is the basic formula that underlies all interest calculations.
The interest rate is often expressed as a percentage and is usually designated as the APR. However, calculating the APR doesn't always reflect the effects of compounding, so the effective annual rate is used instead.
To calculate the applicable interest rate, you may need to convert an annual rate to a monthly rate. For example, if a savings account pays 3% interest on the average balance, the account may award 0.25% (3% / 12 months) each month.
The amount of interest assessed each period will likely change, especially for loans where borrowers have made payments that reduce the principal balance, resulting in lower interest.
Interest and Exchange Rates
Interest and Exchange Rates play a crucial role in determining the borrowing cost. A higher interest rate can make borrowing more expensive, while a lower interest rate can make it more affordable.
The exchange rate of a currency can also impact the borrowing cost, as it affects the value of the loan in the borrower's home currency. For example, if the exchange rate is unfavorable, a borrower may end up paying more for the loan than they anticipated.
A 1% change in the interest rate can result in a 1% change in the borrowing cost, making it essential to monitor interest rates when borrowing.
History of Rates
The history of interest rates dates back to ancient civilizations, with evidence of lenders charging interest as far back as 2000 BC in ancient Babylon.
Interest rates have fluctuated significantly over the centuries, with the Roman Empire imposing a maximum interest rate of 12% in the 4th century AD.
In the Middle Ages, interest rates were often high and variable, with some lenders charging as much as 50% per year.
The gold standard, which pegged currencies to the value of gold, was introduced in the 19th century and helped to stabilize interest rates.
The gold standard was abandoned in the 1970s, leading to a significant increase in interest rates as governments struggled to control inflation.
In the 1980s, interest rates rose to historic highs, peaking at 20% in the US in 1981.
The introduction of floating exchange rates in the 1970s allowed interest rates to be set independently of the gold standard, giving central banks more control over monetary policy.
Central banks have used interest rates as a tool to manage the economy, with the Federal Reserve in the US reducing interest rates to 0% during the 2008 financial crisis.
Foreign Exchange Differences and Hedging
Foreign exchange differences can be a significant concern for companies with international borrowings. They can be integrated into eligible borrowing costs, but caution is essential in determining to what extent these differences constitute adjustments to interest costs.
Entities must establish their own accounting policy for dealing with exchange differences, often necessitating judgement, as indicated in IAS 23.11.
Exchange differences from foreign currency borrowings are commonly integrated into eligible borrowing costs, but other potential causes of exchange differences must be considered.
For example, Entity A, with EUR as its functional currency, borrows USD 1 million on 1 January 20X1, to be repaid on 31 December 20X1, with a fixed interest rate of 3%. The EUR/USD rate is 1.2 on 1 January 20X1 (i.e., 1 EUR = 1.2 USD) and 1.1 on 31 December 20X1. An equivalent loan in EUR would have an interest of 4%. Entity A calculates the eligible exchange differences for capitalisation as presented below:
Companies might use derivatives, like interest rate swaps, to hedge against foreign currency risks. The accounting policies for such entities should clarify whether borrowing costs encompass the payments and accruals of interest under the swap, and any changes in the swap’s fair value.
Borrowers and Lenders
Borrowers are individuals or businesses that take out loans to finance their activities, and lenders are the ones who provide the funds. Borrowers typically pay interest on the loan, which is the cost of borrowing.
Lenders can be individuals, financial institutions, or organizations that provide loans to borrowers. In the case of personal loans, lenders may charge higher interest rates to compensate for the risk of lending to individuals.
Interest rates on loans can vary depending on the lender and the borrower's creditworthiness. For example, a borrower with a good credit score may qualify for a lower interest rate than someone with a poor credit score.
Third-Party Asset
Third-Party Assets can be qualified for capitalization, as long as they meet the general IAS 23 criteria.
Assets constructed by a third party, such as a contractor, can be capitalized if they meet these criteria.
Borrowers
Borrowing costs can be a real expense for borrowers, requiring a cash outlay and often paid before any principal balance can be paid down.
Entity A, for example, had $500,000 of general borrowings on 1 January 20X1, which increased to $1.5 million on 1 July 20X1, with interest expense of $50,000 for the full year 20X1.
The capitalisation rate, which represents the weighted average of borrowing costs, was 5% in Entity A's case.
Borrowing costs can also compound and become overwhelming for a borrower to overcome.
Here are some key characteristics of borrowing costs:
- Is a real expense requiring cash outlay
- Is usually paid before any principal balance can be paid down
- May compound and become overwhelming for a borrower to overcome
- Are contractually obligated to be paid
In fact, Entity A capitalised $20,417 of borrowing costs, which is a significant expense for the entity.
Lenders
As a lender, you may find that providing a source of cash flow through interest payments can be a reliable way to earn a passive income, especially if the borrower is reliable in their payments.
Interest payments can be collected monthly or frequently, providing a consistent stream of income. This can be a more efficient use of capital instead of not lending it out.
However, lending can also increase a taxpayer's tax liability, which is worth considering when making investment decisions.
It's also worth noting that the interest earned from lending may be lower than what could have been earned had the lender deployed capital for their own investment purposes.
Here are some key benefits and drawbacks to consider:
- May provide source of cash flow if interest payments are collected monthly/frequently
- May be a passive source of income
- May provide a consistent stream of income if the borrower is reliable in their payments
- Is a more efficient use of capital instead of not lending it out
- Will increase a taxpayers tax liability
- May be lower than what could have been earned had the lender deployed capital for their own investment purpose
- May attract negative attention in some situations depending on the borrower, rate of interest, and circumstance
Advantages and Disadvantages
Borrowing cost can have both positive and negative effects on individuals and businesses. Paying interest on a loan can be a way to build credit history.
Paying interest can also be a means to effectively use leverage, as seen in real estate development where borrowers use someone else's money to make a profit.
However, interest is a recurring cash expense that can be overwhelming for consumers. Monthly payments are often applied to interest assessments before paying down the principal.
Having too many loans or high monthly payments can restrict a borrower's ability to take out more credit. This can lead to financial strain and difficulty managing debt.
