Welcome to the World of Incomplete Records!

Hello future accountants! This chapter tackles a very common, real-world scenario: figuring out how much profit a business made when their records aren't perfectly kept. Maybe they lost some receipts, or they only track cash and bank transactions, ignoring debtors and creditors properly. We call this working with Insufficient Records (or sometimes, the 'Single Entry System').

The Goal: To calculate the final profit (or loss) without being able to prepare a traditional Income Statement.

Why this is important: Small businesses often start this way. Knowing this method ensures you can still measure their success!

The Challenge: Why Can't We Use the Normal Method?

Normally, profit is calculated using the Income Statement:

Sales - Cost of Goods Sold - Expenses = Profit

When records are incomplete, we are often missing the totals for:

  • Total Sales for the year
  • Total Purchases for the year
  • Accurate records of all expenses

Because we can't trust the figures needed for the Income Statement, we must use a different approach based on measuring the change in the owner's wealth in the business.

The Solution: The Comparison of Capital Method (Statement of Affairs)

Instead of looking at the transactions (Sales and Expenses), we look at the business’s overall Net Worth (its Capital) at the beginning and end of the year.

Analogy: Imagine your personal bank account. If your savings increased by \$1,000 this year, but you also withdrew \$200 for personal shopping (Drawings), your *real* earnings must have been \$1,200. We are using the same logic for the business.

The core concept is simple:

If the owner's investment (Capital) has increased during the year, that increase—after adjusting for any money added or taken out by the owner—must be the profit.

Key Term: The Statement of Affairs (SOA)

When records are incomplete, we cannot prepare a formal Balance Sheet, so we prepare a document called the Statement of Affairs (SOA).

A Statement of Affairs is essentially the same as a Balance Sheet: it lists all Assets and Liabilities on a specific date.

It is used to find the missing figure: Capital.

The fundamental accounting equation still applies:

$$ \text{Assets} - \text{Liabilities} = \text{Capital} $$

Did you know? This method works because even if the business isn't keeping a full set of double entry books, it usually still knows what it owns (assets) and what it owes (liabilities) at the end of the year.

Step-by-Step 1: Calculating Capital

You must calculate the Capital for two specific dates:

  1. Opening Capital: Use the list of Assets and Liabilities available at the beginning of the financial year (e.g., 1 January 2024).
  2. Closing Capital: Use the list of Assets and Liabilities available at the end of the financial year (e.g., 31 December 2024).

Note: You need to be careful to include adjustments like depreciation, accrued expenses, and prepaid expenses when calculating the final list of assets and liabilities for the Closing SOA, just like you would for a standard Balance Sheet.

| Assets (e.g., Fixtures, Inventory, Receivables, Bank) | XXX | | Liabilities (e.g., Payables, Loans, Accruals) | (XX) | | Capital (The Missing Figure) | XXX |

Step-by-Step 2: The Profit Calculation Formula

Once you have the Opening Capital and the Closing Capital figures, you can rearrange them to find the profit. We need to adjust the difference for two key items:

  1. Drawings: Money or goods taken out by the owner. If the owner took money out, the Capital would be lower, so we must ADD Drawings back to find the true profit.
  2. Additional Capital: Money invested by the owner during the year. If the owner added money, the Capital would be higher, so we must SUBTRACT this addition because it wasn't profit earned.

Don't worry if this seems tricky at first! Remember that Drawings reduce Capital, but they don't reduce the *profit* the business actually earned. Additional Capital increases Capital, but it isn't *profit*.

The standard format for calculating profit using the Comparison of Capital method is:


Calculation of Profit (or Loss)

Closing Capital at End of Year (31 Dec)
ADD: Drawings made during the year
Total Adjusted Closing Capital
LESS: Opening Capital at Start of Year (1 Jan)
LESS: Additional Capital introduced during the year
Net Profit (or Loss) for the Year


The Formula (The only one you truly need to memorise!):

$$ \text{Profit} = \left( \text{Closing Capital} + \text{Drawings} \right) - \left( \text{Opening Capital} + \text{Additional Capital} \right) $$

If the final result is a positive number, it is a Net Profit. If the final result is a negative number, it is a Net Loss.

Putting It Into Practice: A Worked Example

Let's look at a simple scenario for Bala's Bikes:

Date Assets Liabilities Capital (A - L)
1 January 2024 (Start) \$55,000 \$15,000 \$40,000 (Opening Capital)
31 December 2024 (End) \$72,000 \$12,000 \$60,000 (Closing Capital)

Additional Information:

  • Bala took Drawings during the year: \$8,000
  • Bala introduced Additional Capital during the year: \$3,000

The Profit Calculation:

Closing Capital (\(31^{st}\) Dec)

\$60,000

ADD: Drawings

+\$8,000

Total Adjusted Closing Capital

\$68,000


LESS: Opening Capital (\(1^{st}\) Jan)

-\$40,000

LESS: Additional Capital Introduced

-\$3,000

Net Profit for the Year

\$25,000

The business increased its net worth by \$25,000 after accounting for all of Bala's personal investments and withdrawals.

Common Mistakes to Avoid

1. Mixing Up Drawings and Additional Capital:

  • Mistake: Students often subtract Drawings and add Additional Capital.
  • Remember: Drawings reduce the final Capital figure, so you ADD them back to reverse the effect. Additional Capital increases the figure, so you SUBTRACT it because it wasn't earned profit.

2. Forgetting to Use the SOA:

  • If the question gives you a list of assets and liabilities, you must first calculate Opening and Closing Capital using Assets minus Liabilities before you can start the profit calculation.

3. Ignoring Depreciation/Bad Debts:

  • Just because the records are incomplete doesn't mean you ignore standard adjustments! Make sure assets like non-current assets (e.g., machinery) are valued at their net book value (cost minus accumulated depreciation) in the closing Statement of Affairs.

Key Takeaway and Summary

When records are insufficient, we cannot use the standard Income Statement. Instead, we use the Comparison of Capital Method.

Quick Review Box

The Process:

  1. Prepare the Opening Statement of Affairs (SOA) to find Opening Capital.
  2. Prepare the Closing Statement of Affairs (SOA) to find Closing Capital.
  3. Use the profit formula:
    Closing Capital + Drawings - Opening Capital - Additional Capital = Profit

Mastering this method is a crucial skill. It demonstrates that you understand the fundamental link between a business's assets, liabilities, and its ultimate success (profit)! Keep practicing those SOA calculations!
