An adjustment trail is a table that starts from a draft figure and applies each adjustment on its own line, with a running total. It appears whenever a question gives you a draft profit and a list of year-end corrections, and it keeps five or six changes from turning into a pile of loose numbers.
This skill belongs to accounting working and revision, and it relies on the year-end ideas in accruals and prepayments and depreciation and asset disposal.
Why lay the working out as a trail?
Most lost marks in adjustment questions come from a missed item or a sign error, not from not knowing the rule. A trail makes both visible. Each line has one item, one sign and one running total.
The trail also shows the marker your method. If one figure is wrong, the other lines can still earn credit.
How to build the trail, step by step
- Write the starting figure first, labelled “Draft net profit” (or whichever figure the question gives).
- Create one line per adjustment, in the order the question lists them.
- For each line, decide the effect on profit. An expense not yet recorded lowers profit. An expense recorded but not yet used up, such as a prepayment, raises it. Income recorded early lowers it.
- Write the working beside the line, then the signed amount.
- Update the running total after every line, and finish with the adjusted figure at the bottom.
- Check the arithmetic a second time by adding all the plus items and all the minus items separately.
Worked example
Kedai Runcit Maju has a draft net profit of RM24,000 for the year ended 31 December. The owner then lists four adjustments.
- Rent of RM800 was paid in advance for next year and charged in full this year.
- Electricity of RM350 for December has not been recorded.
- Equipment costing RM12,000 is depreciated at 10% a year on cost. No depreciation has been recorded.
- Trade receivables are RM9,000. The allowance for doubtful debts should be 5% of receivables. The existing allowance is RM200.
| Item | Working | Effect | Running total (RM) |
|---|---|---|---|
| Draft net profit | given | 24,000 | |
| Rent prepaid | already charged, so remove it | + 800 | 24,800 |
| Electricity accrued | expense not yet recorded | − 350 | 24,450 |
| Depreciation | 10% × 12,000 = 1,200 | − 1,200 | 23,250 |
| Allowance increase | 5% × 9,000 = 450, less existing 200 = 250 | − 250 | 23,000 |
Adjusted net profit: RM23,000.
Check: plus items total 800. Minus items total 350 + 1,200 + 250 = 1,800. So 24,000 + 800 − 1,800 = 23,000. Both methods agree.
The mistake to watch for
The usual slip is to charge the whole allowance, not just the increase.
Mistaken line: Allowance for doubtful debts, 5% × 9,000 = 450, so − 450. Final profit 22,800.
The existing allowance of RM200 has already reduced earlier profit. Only the extra RM250 belongs to this year’s profit.
The correction is to ask “what is the new allowance, what is the old one, and what is the difference?” before you write the line. If the new allowance is lower than the old one, the difference is added to profit instead.
Check yourself
1. A draft net profit is RM15,000. Wages of RM600 are owed at year end and unrecorded. Insurance of RM400 was paid in advance and charged in full. Depreciation of RM900 has not been recorded. Find the adjusted profit.
Show answer
15,000 − 600 (accrued wages) + 400 (prepaid insurance) − 900 (depreciation) = RM13,900.
Check: plus 400, minus 600 + 900 = 1,500, and 15,000 + 400 − 1,500 = 13,900.
2. Receivables are RM6,000 and the allowance should be 4%. The existing allowance is RM300. What is the effect on profit?
Show answer
New allowance = 4% × 6,000 = RM240. It is lower than the old RM300, so the allowance falls by RM60. Profit rises by RM60.
3. A draft profit of RM30,000 needs three adjustments: + 500, − 1,200 and − 300. Show the running totals.
Show answer
30,000 + 500 = 30,500. 30,500 − 1,200 = 29,300. 29,300 − 300 = 29,000.
Check: 500 − 1,200 − 300 = −1,000, and 30,000 − 1,000 = 29,000.
Where this leads next
Once the trail feels natural, learn to reconcile two answers that start from different figures, then try the mixed practice set. The percentage-base explorer shows what each percentage is applied to, and the double-entry and ledger trainer lets you check the entries behind each adjustment.
Some students know every adjustment rule but lose track of signs once a question grows long. Our teachers can look at exactly that pattern in online one-to-one Accounting tuition.
