Reconstructed figures are estimates built from partial evidence, not records. A good answer calculates them correctly and then says plainly what they cannot prove.
This lesson closes incomplete records and links to the judgement skills in accounting concepts and changing practice.
What can go wrong with a reconstruction?
Each method rests on something that may not hold.
The receivables and payables accounts assume that the opening and closing balances are right and that no transaction was left out. A margin assumes that the usual pricing applied all year. The net-asset method assumes every asset and liability was found and valued sensibly.
Three problems recur.
Inputs may be estimated, such as closing inventory counted by hand. Items may be missing, such as cash taken from the till and never noted. The assumptions may have changed, such as a sale price cut in the final month.
How do you cross-check a figure?
Find the same figure by a second route and compare. A gap does not prove fraud or error, but it tells you where to look. A close match raises confidence without giving certainty.
Worked example
Dapur Nenek Café has no sales records. The owner supplies the following for the year.
- Cash banked from the till: RM61,000
- Expenses paid from the till before banking: RM3,000
- Cash the owner took from the till: RM4,200
- Opening inventory RM5,000; purchases RM48,000; closing inventory RM4,000
- The café usually earns a gross margin of 25% on sales
Route 1, cash: sales = 61,000 + 3,000 + 4,200 = RM68,200.
Route 2, margin: cost of sales = 5,000 + 48,000 − 4,000 = 49,000. Cost is 75% of sales, so sales = 49,000 / 0.75 = RM65,333 (to the nearest ringgit).
Gap: 68,200 − 65,333 = about RM2,867.
Reading the gap: sales from the cash route are higher than the margin route implies. Possible reasons: the margin was lower than 25% in some months because of discounts, food was wasted or given to staff and not recorded, or goods taken by the owner raised cost without matching sales. None can be confirmed from the figures given.
The mistake to watch for
A student treats the answer as fact.
Mistaken statement: “Sales were RM68,200, so the accounts are accurate.”
The student presented one calculation as proof. The second route disagrees by RM2,867, and the first route depends on the owner’s estimate of cash taken.
The correction is to say what the figure rests on: “Sales are estimated at RM68,200 from cash banked, but a margin check implies about RM65,333, so the figures should be treated with caution until the gap is explained.”
Check yourself
1. Cost of sales is RM21,000 and the usual margin is 30% on sales. Expected sales are RM30,000 but the reconstructed figure is RM27,500. Find the gap.
Show answer
Expected sales = 21,000 / 0.70 = 30,000. Gap = 30,000 − 27,500 = RM2,500. The business may have sold at lower prices, lost stock or missed recording income.
2. Give one reason why a reconstructed profit may be overstated and one reason it may be understated.
Show answer
Overstated: closing inventory was counted too high, which lowers cost of sales. Understated: an expense was paid in cash by the owner and never recorded, or a sale was missed. Any pair that names the item and the effect is acceptable.
3. Write one sentence evaluating a profit figure found from a net-asset calculation.
Show answer
“The profit depends on the owner’s valuation of inventory and premises at both dates, so a change of valuation would change the profit directly.”

Evaluation answers improve fastest when someone reads your sentences and asks “so what?” That is a normal part of online one-to-one Accounting tuition.
