Split each loan instalment using the lender’s supported allocation between principal, interest and any additional charges. Debit the loan liability for principal, debit interest expense or the appropriate interest account for the borrowing cost, and credit bank for the total paid. An instalment is not normally one undifferentiated operating expense.
Begin with the repayment schedule
A fixed monthly payment does not mean principal and interest remain fixed each month. For a reducing-balance arrangement, the allocation generally changes as the outstanding amount changes. Use the actual agreement, amortisation schedule and lender statement rather than repeating last month’s split indefinitely.
Check whether the schedule is current after rate changes, prepayments, moratoria or delayed payments. A calculation prepared when the loan was first drawn may no longer explain the bank’s latest deduction.
Identify the loan account number and period covered. Businesses with several facilities can pay similar amounts on nearby dates, so the bank debit alone is not a reliable allocation instruction.
Illustrative regular instalment
A Ludhiana workshop pays an instalment of ₹28,000. The lender’s statement allocates ₹22,000 to principal and ₹6,000 to current-period interest. Assume no interest accrual or additional fee has already been recorded.
| Account | Debit ₹ | Credit ₹ |
|---|---|---|
| Term loan payable | 22,000 | — |
| Interest expense | 6,000 | — |
| Business bank | — | 28,000 |
| Total | 28,000 | 28,000 |
If opening principal was ₹5,00,000 and no other principal movement occurred, closing principal becomes ₹4,78,000. The full ₹28,000 reduces bank, but only ₹6,000 affects expense under the stated assumptions.
Debiting the entire instalment to interest would overstate the cost and leave the borrowing liability unchanged. Debiting it entirely to the loan would understate interest and reduce principal too far.
Clear interest already accrued
Suppose the ₹6,000 interest was recognised at the previous month end by debiting Interest expense and crediting Interest payable. On payment, debit Interest payable ₹6,000 rather than expense again.
The complete payment would then debit Loan payable ₹22,000 and Interest payable ₹6,000, and credit Bank ₹28,000. The principal reduction is unchanged; only the route used for the interest component differs because it was previously accrued.
Where the lender’s interest differs from the accrual, investigate the dates, outstanding balance and rate. Record a supported adjustment to the estimate. Avoid sending a material difference to round-off merely because that clears the payable.
Additional fees need separate classification
A bank deduction may include an instalment plus a late fee, returned-payment charge, insurance premium or tax on a service charge. Obtain the breakup and assign each component to its supported account.
For example, an illustrative ₹28,590 bank debit might contain the ₹28,000 instalment and a separately invoiced ₹590 service charge. The extra amount should not automatically be added to principal or interest. Its expense and tax treatment require the underlying advice.
This also improves management reporting. Repeated late charges reveal a different problem from ordinary interest arising under an agreed financing arrangement.
Prepayments change the next reconciliation
An extra payment may reduce principal immediately, sit temporarily in a loan suspense account or be applied according to the agreement. Confirm the lender’s treatment before assuming the entire transfer has reduced borrowing.
If a supported ₹1,00,000 prepayment is fully applied to principal, debit Loan payable ₹1,00,000 and credit Bank ₹1,00,000. Record any separate prepayment charge according to its own documentation and accounting treatment.
Obtain the revised repayment schedule. Future instalment amounts, tenure or principal-interest allocations may change. Continuing the old split after a prepayment can create a growing difference between the ledger and the lender statement.
Failed collections and duplicate debits
A scheduled auto-debit can fail and be retried. Match actual bank transactions with the lender’s receipts. Do not record both the scheduled instruction and the successful debit as payments if only one transfer completed.
Where a bank debit is reversed, reverse the payment through the same principal and interest accounts as appropriate. A reversal restores the unpaid balance; it does not create new borrowing income.
Keep bounced-payment fees distinct from the reversed instalment. Their validity and tax treatment depend on the supporting documents, even when they appear on the same statement date.
Reconcile a full loan roll-forward
Start with opening principal, add new drawdowns and supported capitalised or other principal movements, and subtract principal repayments. Compare the resulting closing amount with the lender’s principal balance, not with a statement total that also includes accrued interest or fees.
Maintain interest incurred, interest paid and interest outstanding separately. AS 1’s accrual principle explains why the expense can differ from cash paid during the month. Some borrowing costs may require different treatment under the applicable accounting framework, so the debit is not universally an immediate expense.
Make the voucher explain the split
A useful narration identifies the loan, instalment period, principal, interest and lender statement reference. Attach the calculation or advice rather than crowding the narration with the entire repayment table.
Use a calculation as a cross-check
For a simple illustrative monthly calculation, opening principal of ₹4,80,000 at an assumed one percent monthly interest rate gives ₹4,800 interest. A ₹28,000 instalment would then contain ₹23,200 principal, if the agreement uses that exact basis and no other component exists.
This calculation is a reasonableness check, not a replacement for the contract. Daily interest, changed rates and payment dates can produce a different amount. Keep any independent calculation alongside the lender allocation and resolve differences before repeating the split in future months.
The instalment entry is complete when the bank deduction, principal reduction and interest recognition reconcile independently. That separation makes both the remaining debt and the actual financing cost credible.
