A business can pay an expense before receiving the related service, or receive the service before paying the bill. The bank payment and the expense belonging to the accounting period are therefore not always the same amount.
Accruals and prepayments deal with that difference in timing. An accrued expense belongs to the current period but remains unpaid. A prepaid expense has been paid but relates to a later period.
For O Level Accounting, begin by asking when the service was used. Only then connect the expense to payments, opening balances and closing adjustments. Students building these foundations can explore O Levels Accounting at Abeel Eschool.
Separate payment from the period of benefit
Suppose a business pays for insurance covering twelve months. The payment leaves the bank on one date, but the insurance benefit extends over the whole covered period.
If the accounting year ends before that coverage finishes, some of the payment relates to future months. Charging the entire amount as the current year’s insurance expense would include a future-period benefit.
Now consider electricity used in December but paid in January. If the accounting year ends in December, the cost of that December usage belongs to the ending period even though cash leaves later.
These examples point in opposite directions, but they use the same principle: match the expense to the relevant period rather than treating the payment date as the only evidence.
An accrued expense is an amount still owed
Imagine total electricity relating to the year is PKR 15,000. The business has paid PKR 12,000, and PKR 3,000 remains unpaid at the year-end.
The expense for the year is PKR 15,000. The closing accrual of PKR 3,000 represents an obligation for a service already received.
In a simplified adjustment, debit electricity expense PKR 3,000 and credit accrued expenses PKR 3,000. This increases the recognised expense and records the unpaid liability.
Do not describe the accrual as an extra bank payment. No payment is created merely by recognising the amount owed. The later settlement of that liability is a separate transaction.
A prepaid expense is a future benefit
Suppose a business pays PKR 48,000 on 1 October for twelve months’ rent, covering October through the following September. Assume the accounting year ends on 31 December and the benefit is allocated evenly by month.
Three months relate to the ending year, so the expense is PKR 48,000 × 3/12 = PKR 12,000. The remaining nine months, worth PKR 36,000, are prepaid at the year-end.
If the full payment was initially debited to rent expense, the closing adjustment debits prepaid rent and credits rent expense for PKR 36,000. This removes the future-period portion from the current expense.
The prepaid amount is an asset representing a benefit still available. It is not an unpaid liability, because the payment has already been made.
Use a timeline before a formula
Draw the start and end of the accounting period. Mark the service coverage dates and payment date. Then identify which months fall inside the reporting period.
This is particularly useful when the accounting year differs from the calendar year. A payment made in April may cover months across two accounting periods, depending on the business’s year-end.
Count months consistently. A twelve-month policy beginning on 1 October runs through the following 30 September. If the year ends on 31 December, October, November and December are the three current-period months in the simplified example.
Follow any explicit daily or monthly apportionment policy in the question. Do not impose an evenly divided monthly assumption if the stated arrangement uses another basis.
Opening accruals relate to the previous period
Suppose cash payments for an expense during the year total PKR 24,000. There is an opening accrued expense of PKR 2,000 and a closing accrued expense of PKR 3,000. Assume the payments include settlement of the opening accrual and there are no prepayments.
The current-period expense is PKR 24,000 − PKR 2,000 + PKR 3,000 = PKR 25,000.
The opening accrual is subtracted because it was recognised as an expense of the previous period, although it was paid this year. The closing accrual is added because it belongs to the current period but has not yet been paid.
This explanation is more reliable than memorising a sequence of signs. Ask which part of the cash payments belongs elsewhere and which current-period cost is still missing.
Opening prepayments become part of current-period expense
Assume payments during the year total PKR 36,000, opening prepaid expense is PKR 4,000 and closing prepaid expense is PKR 6,000. Assume the opening benefit is consumed during the current year and there are no accruals.
The current-period expense is PKR 36,000 + PKR 4,000 − PKR 6,000 = PKR 34,000.
The opening prepayment adds a current-year benefit paid for earlier. The closing prepayment removes part of this year’s payments that relates to a future period.
A student who subtracts both opening and closing prepayments treats the two balances as if they have the same role. Their timing is different: one is brought into the year, while the other is carried out of it.
Combine adjustments only after understanding each one
For a simple expense account with all relevant payments and no other complications, the period expense can be expressed as payments plus closing accrual minus opening accrual plus opening prepayment minus closing prepayment.
For example, payments of PKR 50,000, opening accrual of PKR 2,000, closing accrual of PKR 3,000, opening prepayment of PKR 1,000 and closing prepayment of PKR 4,000 produce an expense of PKR 48,000.
The calculation is 50,000 − 2,000 + 3,000 + 1,000 − 4,000. Each adjustment should have a sentence explaining its timing.
Do not use the expression blindly when the question includes refunds, write-offs, incorrect entries or coverage details that change the interpretation. Read what the payments and balances actually contain.
Keep the financial-statement effects separate
An accrued expense usually increases the current-period expense and creates or increases a current liability in these introductory examples. If omitted, expense and liabilities can both be understated.
A closing prepayment usually reduces the current-period expense and records a current asset. If omitted after the full payment was expensed, expense can be overstated and assets understated.
The income statement and statement of financial position use related but different figures. The expense charge is a period amount; the accrual or prepayment is a balance at a date.
Do not copy the annual expense into the statement of financial position merely because it came from the same account. Label the amount requested before transferring it into a statement.
Explain the ledger entries in ordinary language
A closing accrual records an expense that has been incurred but not yet recorded as paid. The debit increases the expense, while the credit recognises the amount owed.
A closing prepayment adjustment, when the full payment was initially expensed, removes the unconsumed future benefit from the expense account. The debit records the asset and the credit reduces the expense.
Opening balances then need to be handled according to the accounting method and ledger format used in the exercise. Some teaching approaches use reversals, while others work directly through the expense account and balances.
Follow your syllabus and teacher’s required presentation. The underlying timing explanation should remain consistent even when the layout differs.
Do not confuse an invoice date with the service period
An invoice issued after the year-end may relate to service used before it. An invoice issued before the year-end may cover future months. The document date is useful evidence but is not the whole analysis.
Read the coverage dates, meter period, rental period or contract terms supplied in the question. Identify which portion belongs to the reporting period.
For example, a bill covering December and January cannot automatically be charged wholly to either year if the question requires allocation between them. Separate the portions using the stated basis.
Equally, do not invent an accrual merely because the invoice arrives later. The relevant issue is whether an expense for the current period has been incurred and remains unrecorded or unpaid under the exercise’s facts.
Check that a payment has not been counted twice
When an opening accrual is paid during the year, that payment settles an amount already recognised previously. Recording it again as a new current-period expense without the opening-balance adjustment can double count the cost across periods.
A similar issue occurs with opening prepayments. The earlier cash payment should not be recorded again, but the benefit used this year needs to enter the current expense charge.
Trace each amount using two questions: when was cash paid, and which period receives the benefit? Recording the answers in separate columns can reveal a duplicated payment or a missing allocation.
If your ledger appears to disagree with your direct calculation, compare the opening balances and closing adjustments before changing the payment total.
Use small practice pairs to improve accuracy
Create two versions of the same problem. In one, a service is used before payment; in the other, payment occurs before service. Explain which creates an accrual and which creates a prepayment.
Next, add opening balances and calculate the expense again. Change one amount at a time so the effect of the adjustment is visible.
Finally, attempt a mixed financial-statement question where the adjustment is one part of a larger task. This tests whether you can recognise the issue when the worksheet heading no longer announces it.
Use Abeel’s Cambridge past-paper guide for independent attempts and correction. The parent progress guide can help families discuss an explained calculation rather than only the number of lessons viewed.
Bring the timing issue to your teacher
A useful question shows the accounting year, coverage dates, payments and opening and closing balances. Explain which amount you think belongs to the year and where you became unsure.
After feedback, attempt a fresh version without viewing the correction. The aim is to allocate the expense independently, not reproduce a memorised formula.

Frequently asked questions
What is an accrued expense?
It is an expense belonging to the current period that remains unpaid at the relevant date in these introductory examples. It normally creates a liability.
What is a prepaid expense?
It is an amount already paid for a benefit relating to a later period. The unused future portion is recorded as an asset.
Why is an opening accrual subtracted from payments?
When payments include settlement of that opening liability, the amount relates to expense recognised previously. Subtracting prevents it being charged again to the current year.
Why is an opening prepayment added to expense?
It can represent a benefit used this year but paid for earlier. The expense is recognised when that benefit belongs to the period.
Is the bank payment always the expense for the year?
No. Adjust for the period of benefit and relevant opening and closing accruals or prepayments, following the question’s facts.
