Preparing the Reconciliation Statement of Cost and Financial Profit

Updated 10 October 2026 · Fact-checked

A reconciliation statement starts with profit as per cost accounts (or financial accounts) and adds or deducts each item that is treated differently in the two sets of books, until it reaches the profit of the other set. Sort every item by direction: does it raise or lower the target profit?

Understand Preparing the Reconciliation Statement

Cost accounts and financial accounts record the same business, but they do not always show the same profit. Financial accounts follow law and accounting standards. Cost accounts serve management and may leave out some items or include others.

A reconciliation statement explains the gap. You start from one profit figure and move item by item to the other. Every item that appears in one set of books but not the other, or is valued differently, becomes an addition or a deduction.

The differences fall into three groups. First, items only in financial accounts, such as interest received, dividend, loss on sale of assets or preliminary expenses written off. Second, items only in cost accounts, such as notional rent or notional interest on capital. Third, items in both sets but at different values, such as stock valuation, depreciation and overhead absorption.

The skill is deciding the direction for each item. Ask one question: if I move from the starting profit to the target profit, does this item make the target profit higher or lower? Higher means add. Lower means deduct.

A statement that starts from cost profit and ends at financial profit is the usual exam format. You can also be asked to work backwards from financial profit to cost profit. The method is the same, but every direction reverses.

Key rules to remember

Cost profit to financial profit: Financial profit = Cost profit + items that raise financial profit − items that lower financial profit; Use this layout when the question gives cost profit and asks for financial profit.
Items only in financial accounts (income): Add: interest received, dividend received, rent received, profit on sale of assets; These are not in cost accounts, so they increase financial profit.
Items only in financial accounts (expense/loss): Deduct: interest paid, loss on sale of assets, preliminary expenses written off, donations, discount allowed, income tax; These are not charged in cost accounts, so they reduce financial profit.
Notional charges: Add: notional rent, notional interest on capital charged in cost accounts only; Cost accounts charged them but financial accounts did not, so financial profit is higher.
Overhead absorption: Cost to financial: Add over-absorption, Deduct under-absorption. Financial to cost: Deduct over-absorption, Add under-absorption; Financial accounts carry actual overheads. Over-absorption means cost accounts charged more overhead to cost than the actual overhead, so cost profit is understated and is added to reach financial profit. Under-absorption means cost accounts charged less than actual, so cost profit is overstated and is deducted. Going from financial to cost, reverse this.
Stock valuation: Closing stock: financial higher than cost = Add; financial lower = Deduct. Opening stock: financial higher than cost = Deduct; financial lower = Add; Opening and closing stock work in opposite directions. These directions are for cost to financial.
Depreciation difference: Depreciation charged in cost accounts higher than in financial = Add the difference; lower = Deduct the difference; Compare the two depreciation figures and take only the difference. This direction is for cost to financial.

How to solve Preparing the Reconciliation Statement questions

Use this method for any reconciliation question. Do the sorting first and the arithmetic last.

1Read the question and note the starting profit and the target profit. Cost to financial is the usual direction.
2List every item given. Tick which ones affect only one set of books and which are valued differently in both.
3Ignore items that appear identically in both sets, such as sales or purchases that agree. They do not belong in the statement.
4For each item, ask: does it make the target profit higher or lower? Mark it Add or Deduct.
5For stock, depreciation and overheads, work out only the difference between the two figures, then decide the direction.
6Write the statement in a proper format: starting profit, an Add section, a Deduct section, and the target profit as the final line.
7Total the additions and deductions separately, then compute the final profit. Check by reversing the statement if time permits.

Quickest way: Direction check with an arrow table

When to use it: Use when the question has many items and you are short of time.

Write each item in rough work with a plus or minus sign next to it, based on the effect on the target profit.
For stock, write the financial figure and the cost figure side by side. Higher closing stock in the target set means plus. Higher opening stock in the target set means minus.
Group all plus items and all minus items, total them, and then write the neat statement.
Cross-check: the net of the plus and minus totals must equal the difference between the two profits if the question gives both.

Common mistakes in Preparing the Reconciliation Statement

Reversing the direction of opening stock.
Students remember the closing stock rule and apply it to opening stock.
Fix: Opening stock is an expense. A higher opening stock value in the target books lowers profit there, so deduct it. Closing stock is the opposite.
Adding or deducting the full depreciation or stock figure instead of the difference.
Students treat the item as an item that appears in only one set of books.
Fix: When both sets show a value, take only the difference between the two figures.
Including notional rent or notional interest as a deduction.
Students think any cost item is a charge against profit.
Fix: These are in cost accounts only. Moving to financial profit, they are added back.
Getting under- and over-absorption the wrong way round.
The words sound alike and students do not compare absorbed with actual.
Fix: Cost to financial: add over-absorbed overheads and deduct under-absorbed overheads. Over-absorption means cost accounts charged more than actual, so cost profit is understated and must go up. Check by asking whether cost accounts charged more or less than actual.
Including items that are the same in both sets, or purely balance sheet items.
Questions list many figures, and students try to use every one.
Fix: Include an item only if it changes profit differently in the two sets. Drawings, capital and share issues are not profit items.
Leaving out the heading or the final profit line.
Students rush to the arithmetic.
Fix: Always start with 'Profit as per cost accounts' and end with 'Profit as per financial accounts' so you earn format marks.

Worked examples

Example 1

Profit as per cost accounts is ₹4,50,000. The following are found: interest received ₹12,000; dividend received ₹8,000; overheads over-absorbed in cost accounts ₹9,000; overheads under-absorbed in cost accounts ₹15,000; preliminary expenses written off ₹5,000; notional rent charged in cost accounts ₹24,000; donations ₹10,000; profit on sale of machine ₹18,000; opening stock ₹1,80,000 in cost accounts and ₹1,70,000 in financial accounts; closing stock ₹2,40,000 in cost accounts and ₹2,20,000 in financial accounts. Prepare the reconciliation statement to find profit as per financial accounts.

Show the solution

Start with cost profit ₹4,50,000.
Additions: interest received ₹12,000; dividend ₹8,000; overhead over-absorbed ₹9,000 (cost accounts charged more than actual, so cost profit is understated); notional rent ₹24,000 (charged only in cost); profit on sale of machine ₹18,000; opening stock difference ₹10,000 (financial opening stock is lower, so financial cost of sales is lower).
Total additions = 12,000 + 8,000 + 9,000 + 24,000 + 18,000 + 10,000 = ₹81,000.
Deductions: overhead under-absorbed ₹15,000 (cost accounts charged less than actual, so cost profit is overstated); preliminary expenses ₹5,000; donations ₹10,000; closing stock difference ₹20,000 (financial closing stock is lower).
Total deductions = 15,000 + 5,000 + 10,000 + 20,000 = ₹50,000.
Financial profit = 4,50,000 + 81,000 − 50,000 = ₹4,81,000.

Answer: Profit as per financial accounts = ₹4,81,000.

Example 2

Profit as per financial accounts is ₹5,60,000. Details: loss on sale of investments ₹14,000; interest on bank deposit ₹6,000; overheads over-absorbed in cost accounts ₹8,000; closing stock ₹3,10,000 in financial accounts and ₹3,25,000 in cost accounts; opening stock ₹2,40,000 in financial accounts and ₹2,30,000 in cost accounts; notional interest on capital charged in cost accounts ₹20,000; depreciation ₹90,000 in financial accounts and ₹1,10,000 in cost accounts. Find profit as per cost accounts.

Show the solution

Start with financial profit ₹5,60,000 and work towards cost profit, so reverse the directions.
Add loss on sale of investments ₹14,000 (not charged in cost accounts, so cost profit is higher).
Deduct interest on bank deposit ₹6,000 (not in cost accounts).
Deduct over-absorption ₹8,000 (cost accounts charged more overhead than actual, so cost profit is lower).
Add closing stock difference ₹15,000 (cost closing stock is higher, so cost profit is higher).
Add opening stock difference ₹10,000 (cost opening stock is lower, so cost of sales in cost accounts is lower).
Deduct notional interest ₹20,000 (charged only in cost accounts) and depreciation difference ₹20,000 (cost charged more).
Additions = 14,000 + 15,000 + 10,000 = ₹39,000. Deductions = 6,000 + 8,000 + 20,000 + 20,000 = ₹54,000.
Cost profit = 5,60,000 + 39,000 − 54,000 = ₹5,45,000.

Answer: Profit as per cost accounts = ₹5,45,000.

Exam tips

Always write the full statement with a heading, an Add section, a Deduct section and a final profit line. Step marks depend on this layout.
Mention a short reason in brackets for each item, such as 'not recorded in cost accounts'. It shows the examiner you understand the direction.
Check whether the question asks for cost to financial or financial to cost before you begin. A wrong starting point loses the whole answer.
In MCQs, look for the one trap: a stock or overhead item whose direction students often reverse. Work it out on paper rather than guessing.
Leave out items that do not affect profit, such as share capital, and say so if you are unsure. Do not force them into the statement.

Preparing the Reconciliation Statement: frequently asked questions

What is the format of a reconciliation statement of cost and financial profit?

It begins with 'Profit as per cost accounts', then lists additions and deductions, and ends with 'Profit as per financial accounts'. Each item has its amount in a separate column or line. Totals of additions and deductions should be clear.

Do I add or deduct over-absorbed overheads?

When moving from cost profit to financial profit, add over-absorbed overheads and deduct under-absorbed overheads. With over-absorption, cost accounts charged more than the actual overheads, so cost profit is understated and must be increased. Going from financial to cost profit, the directions reverse.

How do I treat stock differences?

Compare the cost and financial values. For closing stock, add if financial is higher and deduct if lower. For opening stock, the direction is the opposite: deduct if financial is higher and add if lower. These directions apply when moving from cost profit to financial profit.

Can the question ask for cost profit from financial profit?

Yes. The method is the same, but you reverse every direction. An item you would add going from cost to financial is deducted going from financial to cost.
