IGCSE Accounting — Incomplete Records: Notes, Practice Questions & Worked Solutions

IGCSE Accounting 0452 · Section 5.6: Incomplete Records

Incomplete Records

Many small sole traders don’t keep full double-entry records. This topic is about reconstructing missing figures — profit, sales, purchases — using whatever information is available. (Restricted to sole traders only.)

1. The Statement of Affairs

A statement of affairs is like a statement of financial position, used to calculate capital at a point in time when full records don’t exist: Capital = Assets − Liabilities.

Profit = Closing capital − Opening capital + Drawings − Additional capital introduced

Worked example — finding profit from capital changes Opening capital $10,000, closing capital $14,000, drawings during the year $3,000, additional capital introduced $1,000. Calculate the profit for the year.
Profit = 14,000 − 10,000 + 3,000 − 1,000 = $6,000

2. Mark-up and Margin

Term	Formula
Mark-up	Gross profit as a % of cost of sales
Margin	Gross profit as a % of revenue (sales)

Worked example — using mark-up to find missing figures Cost of sales is $8,000, and the business uses a mark-up of 25%. Calculate the gross profit and the sales revenue.
Gross profit = 8,000 × 25% = $2,000. Sales = 8,000 + 2,000 = $10,000.
(Check: margin = 2,000/10,000 = 20% — mark-up and margin describe the same profit, just as a percentage of different bases.)

Common mistakes to watch for

Applying a mark-up percentage to sales instead of cost of sales — mark-up is always based on cost of sales.
Applying a margin percentage to cost of sales instead of sales — margin is always based on sales.
Forgetting to adjust for drawings and additional capital introduced when calculating profit from the change in capital.

Explain what a statement of affairs is used for.

A sole trader’s assets total $18,000 and liabilities total $5,000 at the start of the year. Calculate the opening capital.

Opening capital $10,000, closing capital $14,000, drawings $3,000, additional capital introduced $1,000. Calculate the profit for the year.

Opening capital $25,000, closing capital $22,000, drawings $6,000, no additional capital introduced. Calculate the profit or loss for the year.

Define mark-up.

Define margin.

Cost of sales is $8,000, and the business uses a mark-up of 25%. Calculate the gross profit and the sales revenue.

Sales revenue is $20,000, and the business uses a margin of 30%. Calculate the gross profit and the cost of sales.

Incomplete Records — Practice: Solutions

Purpose of a statement of affairs.

✓A statement of affairs is used to calculate a sole trader’s capital at a point in time (Capital = Assets − Liabilities), when full double-entry records are not available.

Assets $18,000, liabilities $5,000. Find opening capital.

Capital = Assets − Liabilities

18,000−5,000

✓$13,000

Opening $10,000, closing $14,000, drawings $3,000, capital introduced $1,000.

Profit = Closing − Opening + Drawings − Capital introduced

14,000−10,000+3,000−1,000

✓$6,000

Opening $25,000, closing $22,000, drawings $6,000, no capital introduced.

Profit = Closing − Opening + Drawings

22,000−25,000+6,000

✓$3,000 profit

Define mark-up.

✓Mark-up is gross profit expressed as a percentage of cost of sales.

Define margin.

✓Margin is gross profit expressed as a percentage of revenue (sales).

COS $8,000, mark-up 25%.

Gross profit = COS × mark-up

8,000×0.25=2,000

✓Gross profit = $2,000; Sales = 8,000+2,000 = $10,000

Sales $20,000, margin 30%.

Gross profit = Sales × margin

20,000×0.30=6,000

✓Gross profit = $6,000; Cost of sales = 20,000−6,000 = $14,000

Why is this topic restricted to sole traders?

✓Reconstructing missing records is more complex for a service or manufacturing business (with additional cost structures like factory overheads or no cost of sales at all), so the syllabus limits incomplete records questions to the simpler, more common case of a sole trader with a straightforward trading business.

Q10

How can mark-up estimate fire-damaged inventory?

✓Using known sales revenue for the period and the business’s usual mark-up percentage, the expected cost of sales can be calculated. Comparing this to the inventory actually available (opening inventory + purchases − known remaining inventory) reveals the value of inventory that must have been lost, since it’s now “missing” from the expected total.
