Interest on Debentures: Journal Entries and Common Mistakes

Interest on debentures looks like a small topic, but it is one of those areas where students lose marks because of one small wrong assumption.

The calculation may be simple. The journal entries may also look repetitive. But the chapter tests whether you understand what a debenture really is.

A debenture is a loan taken by the company. The people who hold debentures are creditors, not owners. So the interest paid to them is not a share of profit. It is the cost of borrowing money.

That one idea controls the whole topic.

Once you keep this in mind, the entries become much easier. You only need to answer four questions:

• On what amount should interest be calculated?
• For how many months is interest due?
• Is tax deducted at source given in the question?
• Has the interest only become due, or has it also been paid?

This blog will build the full logic step by step.

What Interest on Debentures Means

When a company issues debentures, it borrows money from debentureholders. In return, it promises to pay interest at a fixed rate.

If the question says “10% Debentures”, it usually means the company must pay interest at 10% per year on the nominal value of the debentures outstanding.

The word “outstanding” is important. Interest is calculated only on the debentures that are actually in existence for that period.

For example, if a company has Rs. 5,00,000 of 10% debentures outstanding for the full year, the annual interest is:

Particular	Amount
Nominal value of debentures	Rs. 5,00,000
Rate of interest	10% per annum
Interest for one full year	Rs. 50,000

If interest is paid half-yearly, the annual interest is divided into two half-year amounts:

Period	Interest
First six months	Rs. 25,000
Next six months	Rs. 25,000
Total annual interest	Rs. 50,000

The Formula You Should Use

Use this formula for almost every school-level interest calculation:

Step	Formula
Interest on debentures	Nominal value of debentures outstanding x Rate x Time

If time is in months, write it like this:

Step	Formula
Interest	Nominal value x Rate x Number of months / 12

For example, interest on Rs. 3,00,000 of 12% debentures for 6 months is:

Particular	Amount
Nominal value	Rs. 3,00,000
Annual rate	12%
Time	6/12
Interest	Rs. 18,000

The calculation is:

Rs. 3,00,000 x 12/100 x 6/12 = Rs. 18,000

Interest Is Calculated on Nominal Value

This is one of the most important rules.

Interest on debentures is calculated on the nominal value, also called face value, of the debentures. It is not calculated on issue price, redemption price, discount, premium, or bank amount received.

Suppose a company issues 5,000 debentures of Rs. 100 each at Rs. 95.

The company receives Rs. 4,75,000, but the nominal value is Rs. 5,00,000.

If the debentures are 10% debentures, annual interest is calculated on Rs. 5,00,000, not Rs. 4,75,000.

Particular	Amount
Number of debentures	5,000
Face value per debenture	Rs. 100
Nominal value	Rs. 5,00,000
Issue price per debenture	Rs. 95
Bank amount received	Rs. 4,75,000
Interest base	Rs. 5,00,000
Annual interest at 10%	Rs. 50,000

The same rule applies if debentures are issued at premium. If Rs. 100 debentures are issued at Rs. 110, interest is still calculated on Rs. 100 per debenture.

The Basic Entry When Interest Becomes Due

The first entry records the fact that interest has become due.

If no tax deduction is mentioned, the entry is:

Particulars	Debit	Credit
Debenture Interest A/c Dr.	Amount of interest
To Debentureholders A/c		Amount of interest

This entry does two things:

• It records interest expense by debiting Debenture Interest A/c.
• It creates a liability payable to debentureholders.

The company has not necessarily paid the money yet. It has only accepted that the interest is now due.

The Entry When Interest Is Paid

After interest becomes due, the company pays debentureholders.

The payment entry is:

Particulars	Debit	Credit
Debentureholders A/c Dr.	Amount paid
To Bank A/c		Amount paid

This clears the liability created in the due entry.

The important point is that the payment entry does not debit Debenture Interest A/c again. The expense was already recorded when interest became due.

Full Example Without TDS

Suppose ABC Ltd. has Rs. 4,00,000 of 10% debentures. Interest is payable half-yearly on 30 September and 31 March. Ignore tax deduction.

Annual interest is:

Rs. 4,00,000 x 10/100 = Rs. 40,000

Half-yearly interest is:

Rs. 40,000 x 6/12 = Rs. 20,000

Interest Due on 30 September

Particulars	Debit	Credit
Debenture Interest A/c Dr.	Rs. 20,000
To Debentureholders A/c		Rs. 20,000

Interest Paid on 30 September

Particulars	Debit	Credit
Debentureholders A/c Dr.	Rs. 20,000
To Bank A/c		Rs. 20,000

Interest Due on 31 March

Particulars	Debit	Credit
Debenture Interest A/c Dr.	Rs. 20,000
To Debentureholders A/c		Rs. 20,000

Interest Paid on 31 March

Particulars	Debit	Credit
Debentureholders A/c Dr.	Rs. 20,000
To Bank A/c		Rs. 20,000

At the end of the year, total debenture interest is transferred to the Statement of Profit and Loss.

Particulars	Debit	Credit
Statement of Profit and Loss A/c Dr.	Rs. 40,000
To Debenture Interest A/c		Rs. 40,000

This closes Debenture Interest A/c because it is an expense account.

What Changes When TDS Is Given?

TDS means tax deducted at source.

In simple words, the company does not pay the full interest amount to debentureholders. It deducts tax from the interest and later deposits that tax with the government.

For school-level journal entries, the most important point is this:

The debenture interest expense is still the gross interest amount.

The company splits the gross interest into two parts:

• Net amount payable to debentureholders.
• Tax deducted, payable to the government.

If TDS is given in the question, the interest due entry becomes:

Particulars	Debit	Credit
Debenture Interest A/c Dr.	Gross interest
To Debentureholders A/c		Net interest
To Income Tax Payable A/c		TDS amount

Later, when the company pays debentureholders:

Particulars	Debit	Credit
Debentureholders A/c Dr.	Net interest
To Bank A/c		Net interest

And when the tax deducted is deposited:

Particulars	Debit	Credit
Income Tax Payable A/c Dr.	TDS amount
To Bank A/c		TDS amount

Full Example With TDS

Suppose XYZ Ltd. has Rs. 6,00,000 of 12% debentures. Interest is payable half-yearly. Tax is deducted at source at 10%.

Annual interest is:

Rs. 6,00,000 x 12/100 = Rs. 72,000

Half-yearly interest is:

Rs. 72,000 x 6/12 = Rs. 36,000

TDS on half-yearly interest is:

Rs. 36,000 x 10/100 = Rs. 3,600

Net amount payable to debentureholders is:

Rs. 36,000 - Rs. 3,600 = Rs. 32,400

Interest Due

Particulars	Debit	Credit
Debenture Interest A/c Dr.	Rs. 36,000
To Debentureholders A/c		Rs. 32,400
To Income Tax Payable A/c		Rs. 3,600

Net Interest Paid to Debentureholders

Particulars	Debit	Credit
Debentureholders A/c Dr.	Rs. 32,400
To Bank A/c		Rs. 32,400

TDS Deposited

Particulars	Debit	Credit
Income Tax Payable A/c Dr.	Rs. 3,600
To Bank A/c		Rs. 3,600

At year-end, Debenture Interest A/c is transferred to the Statement of Profit and Loss for the full interest amount.

If there are two half-yearly interest periods, the total annual debenture interest is Rs. 72,000.

Particulars	Debit	Credit
Statement of Profit and Loss A/c Dr.	Rs. 72,000
To Debenture Interest A/c		Rs. 72,000

If Interest Is Due But Not Paid

Sometimes interest becomes due, but the company has not paid it by the balance sheet date.

In that case, you still record the due entry because the expense belongs to the year.

If there is no TDS:

Particulars	Debit	Credit
Debenture Interest A/c Dr.	Interest due
To Debentureholders A/c		Interest due

If payment is not made, Debentureholders A/c remains as a liability.

If TDS is involved, Income Tax Payable A/c also remains as a liability until the tax is deposited.

The year-end transfer of Debenture Interest A/c is still made because the interest expense belongs to the current year.

If Interest Has Accrued But Is Not Yet Due

This is slightly different.

Interest due means the payment date has arrived.

Interest accrued but not due means interest has built up with time, but the payment date has not arrived yet.

Suppose interest is payable on 30 June and 31 December, but accounts are prepared on 31 March. Interest for January, February, and March belongs to the current year, but it is not due for payment until 30 June.

In that case, the adjustment entry may be:

Particulars	Debit	Credit
Debenture Interest A/c Dr.	Accrued interest
To Interest Accrued but Not Due A/c		Accrued interest

This is used only when the question requires year-end adjustment for interest accrued but not yet due.

If Debentures Are Issued or Redeemed During the Year

Interest is calculated only for the time the debentures are outstanding.

Suppose a company issues Rs. 2,00,000 of 9% debentures on 1 October. The year ends on 31 March.

The debentures were outstanding for 6 months.

Interest is:

Rs. 2,00,000 x 9/100 x 6/12 = Rs. 9,000

Now suppose the company had Rs. 5,00,000 of debentures outstanding at the start of the year and redeemed Rs. 1,00,000 on 1 January.

For April to December, interest is calculated on Rs. 5,00,000.

For January to March, interest is calculated on Rs. 4,00,000.

Period	Debentures outstanding	Time
April to December	Rs. 5,00,000	9 months
January to March	Rs. 4,00,000	3 months

This is why the timeline matters.

Common Mistakes in Interest on Debentures

Here are the mistakes that appear again and again in notebooks and tests.

Mistake 1: Calculating Interest on Issue Price

If Rs. 100 debentures are issued at Rs. 95, students sometimes calculate interest on Rs. 95 per debenture.

That is wrong.

Interest is calculated on face value, which is Rs. 100 per debenture.

Mistake 2: Forgetting the Time Period

A 12% rate is usually annual. If interest is for 6 months, you must multiply by 6/12.

If the debentures were issued on 1 October, the company does not owe a full year’s interest on 31 March.

Mistake 3: Treating TDS as a Reduction in Expense

If gross interest is Rs. 36,000 and TDS is Rs. 3,600, Debenture Interest A/c is still debited with Rs. 36,000.

The TDS only changes how the payable amount is split.

Mistake 4: Debiting Debenture Interest Again at Payment

The expense is debited when interest becomes due.

At payment, Debentureholders A/c is debited because the liability is being cleared.

Mistake 5: Forgetting the Year-End Transfer

Debenture Interest A/c is an expense account. At year-end, it must be transferred to the Statement of Profit and Loss.

If the question asks for journal entries, this closing entry is often expected.

Mistake 6: Mixing Debentureholders With Debentures

Debentures A/c represents the loan principal.

Debentureholders A/c is used for the interest payable to the holders.

Do not reduce Debentures A/c when paying interest. The principal is not being repaid.

Mistake 7: Inventing TDS When It Is Not Given

If the question does not mention tax deduction, do not assume it.

Use TDS only when the question gives it or clearly asks for it.

A Quick Checklist Before Writing Entries

Before you start journal entries, make this small working note:

Question to ask	What to write
What is the face value outstanding?	Rs. …
What is the annual interest rate?	…%
What is the time period?	… months
Is TDS given?	Yes or No
Has interest become due?	Yes or No
Has interest been paid?	Yes or No
Is a year-end transfer needed?	Yes or No

This takes less than a minute, but it prevents most wrong entries.

The Complete Pattern to Remember

For most questions, the pattern is:

Without TDS

Stage	Entry
Interest due	Debenture Interest A/c Dr. To Debentureholders A/c
Interest paid	Debentureholders A/c Dr. To Bank A/c
Year-end transfer	Statement of Profit and Loss A/c Dr. To Debenture Interest A/c

With TDS

Stage	Entry
Interest due	Debenture Interest A/c Dr. To Debentureholders A/c To Income Tax Payable A/c
Net interest paid	Debentureholders A/c Dr. To Bank A/c
TDS deposited	Income Tax Payable A/c Dr. To Bank A/c
Year-end transfer	Statement of Profit and Loss A/c Dr. To Debenture Interest A/c

Learn this pattern with the logic, not as a blind format.

Debenture Interest A/c records the company’s borrowing cost.

Debentureholders A/c records the amount payable to holders.

Income Tax Payable A/c records the amount deducted and payable to the government.

Bank A/c records the actual cash movement.

Statement of Profit and Loss A/c closes the expense for the year.

Once each account has a job, the entries stop feeling random.

Frequently Asked Questions

Is interest on debentures paid only when the company earns profit?

No. Interest on debentures is payable because the company has borrowed money. It is a charge against profit, so it is recorded even if the company has low profit or no profit.

Is debenture interest calculated on face value or issue price?

It is calculated on face value, also called nominal value. If Rs. 100 debentures are issued at Rs. 95 or Rs. 110, interest is still calculated on Rs. 100 per debenture.

What is the entry for interest due on debentures?

Without TDS, the entry is Debenture Interest A/c Dr. To Debentureholders A/c. This records the expense and creates the liability payable to debentureholders.

What is the entry for payment of debenture interest?

The entry is Debentureholders A/c Dr. To Bank A/c. At this stage, the company is paying the liability that was already created when interest became due.

How is TDS shown in debenture interest entries?

When TDS is given, Debenture Interest A/c is debited with gross interest. Debentureholders A/c is credited with the net amount, and Income Tax Payable A/c is credited with the tax deducted.

Does TDS reduce debenture interest expense?

No. TDS does not reduce the company’s interest expense. It only separates the amount paid to debentureholders from the amount payable to the government.

Why is Debenture Interest A/c transferred to Statement of Profit and Loss?

Debenture Interest A/c is an expense account. At the end of the year, expenses are closed by transferring them to the Statement of Profit and Loss.

What if interest is due but not paid before the year ends?

The due entry is still recorded. Debentureholders A/c remains as a liability until payment is made. Debenture Interest A/c is still transferred to the Statement of Profit and Loss for the year.

Should I use Debentures A/c when paying interest?

No. Debentures A/c represents the loan principal. Interest payment is made through Debentureholders A/c, not by reducing Debentures A/c.

What is the biggest mistake to avoid in this topic?

Do not mix calculation and payment. First calculate the gross interest, then record the due entry, then record the payment entry. If TDS is given, split the gross interest into net payment and tax payable.
