How to make accounting entries for carrying forward costs
When you check out at the end of each month, are you also worried about the "Inventory Goods" and "Main Business Costs" items on your computer screen? Obviously I have sold the goods and collected the money, but I still feel uncertain about how to carry forward the costs – I am afraid that the profit will be inflated if the calculation is under-calculated, I am afraid that the boss will question me if I am over-calculating, and I am even more afraid that a lot of problems will be found during the tax inspection next month. In fact, carrying forward costs is not that mysterious. It is like doing a "cost settlement" for this month's "operating ledger" and moving the costs corresponding to the products/services sold from the "warehouse" to the "income statement" so that revenue and costs can truly be "matched." Today we will break it down and talk about it, from "what it is" to "how to do it" and then to "how to avoid pitfalls". I guarantee that you will be able to get started after reading this and you will not panic when you check out next time.
1. First understand: What are carry-over costs? Why do you have to do this step?
Carrying forward costs, to put it bluntly, means “calculating how much direct costs you have spent on making money this month.” For example, if you open a clothing store and charge 1,000 yuan to sell a piece of clothing, this 1,000 yuan is the income; but you spent 400 yuan to purchase the clothing, and this 400 yuan is the "cost". When checking out at the end of the month, you have to deduct the 400 yuan from "inventory" and record it in "cost", so that you can calculate "600 yuan (1000-400) earned from selling this dress."
Why do you have to do this step? There are three unavoidable reasons:
The boss wants to see the real profit: if he only looks at the income without looking at the cost, the boss will think that he has made a huge profit, but when he calculates the cost and finds that he has lost money, the account will be in vain;
Check the matching degree for taxes: income and costs must correspond. You said you sold 100 items, but the cost was only carried forward for 50 items. The tax system can see the problem at a glance;
I know in my mind: Which product makes money and which product loses money depends entirely on the cost carry-forward data. Otherwise, how can we optimize our operations?
To put it bluntly, carrying forward costs is the "basic skill" of accounting. If you don't do it correctly, the subsequent profits and reports will be wrong.
2. Cost carryover in different industries, entry template + case analysis (apply directly after reading)
The core logic of carrying forward costs is "whatever is sold, the cost will be carried forward." However, the "costs" of different industries are different: the manufacturing industry refers to the "produced products", the commerce industry refers to the "incoming goods", and the service industry refers to the "labor and expenses of providing services". We divide it into industries. Each industry will provide entries and cases, and you will be able to take your seat directly.
(1) Manufacturing industry: the entire process carryover from "raw materials" to "finished products" (the most complex but most typical)
The cost carryover in manufacturing is "one-stop": raw materials are purchased first, then processed into semi-finished products, then finished products, and finally sold. Therefore, the cost carryover must be carried out in four steps, and no step can be missed.
Step one: Receive raw materials (use materials from the warehouse for production)
Entry template:
Borrow: Production costs – direct materials
Credit: raw materials
Case: Company A produces product A and consumes 10 tons of steel this month at a cost of 5,000 yuan per ton, totaling 50,000 yuan.
Entries:
Borrow: Production cost – direct materials 50,000
Credit: Raw materials – steel 50,000
Step 2: Collect production costs (labor, water and electricity bills, etc. are all considered costs)
Producing products not only requires materials, but also requires workers to do the work (direct labor) and power to operate the machines (manufacturing expenses). These are all added to the "production costs".
Direct manual entry:
Borrow: Production costs – direct labor
Loan: Employee compensation payable
Manufacturing overhead entries (collected first, then allocated):
Borrow: manufacturing expenses (such as water and electricity bills, machine depreciation)
Credit: bank deposit/accumulated depreciation
When amortizing at the end of the month:
Borrow: production cost – manufacturing overhead
Credit: manufacturing overhead
Case: Company A produces product A. This month’s workers’ wages are 30,000 yuan, workshop water and electricity bills are 5,000 yuan, and machine depreciation is 10,000 yuan.
Labor accrual:
Borrow: Production cost – direct labor 30,000
Loan: 30,000 employee compensation payable
Collect manufacturing overhead:
Borrow: Manufacturing expenses 15,000 (5,000+10,000)
Loan: bank deposit (water and electricity bills) 5,000
Credit: Accumulated depreciation (machine) 10,000
Allocate manufacturing overhead (assuming all products are supplied to A):
Borrow: Production cost – manufacturing overhead 15,000
Credit: Manufacturing overhead 15,000
Step 3: Complete and put into warehouse (the product is ready and put into the warehouse)
After all costs are collected, the total cost is calculated, and then the "unit cost" is calculated based on the completed quantity, and then the "production cost" is transferred to "inventory goods" (finished goods in the warehouse).
Entry template:
Borrow: Inventory items
Credit: production costs
Case: Company A has completed product A this month. The total cost = direct materials 50,000 + direct labor 30,000 + manufacturing expenses 15,000 = 95,000 yuan. A total of 100 pieces were produced, and the unit cost was 950 yuan/piece.
Entries:
Borrow: Inventory goods – product A 95000
Credit: Production cost – direct materials 50,000
Credit: Production cost – direct labor 30,000
Credit: Production cost – manufacturing overhead 15,000
Step 4: Sales carry forward (how much was sold, how much cost was carried forward)
Finally, we have reached the most critical step: after selling the goods, transfer "inventory goods" to "main business costs" based on sales quantity × unit cost.
Entry template:
Borrow: Main business costs
Credit: Inventory goods
Case: Company A sold 80 pieces of product A this month, with a unit cost of 950 yuan, and the total cost = 80 × 950 = 76,000 yuan.
Entries:
Borrow: Main business cost 76,000
Credit: Inventory goods – Product A 76,000
Note: The "sales quantity" here must be consistent with the "outbound order" and "sales invoice". Do not transfer more or less, otherwise the inventory and accounts will not be reconciled!
(2) Commercial industry: simple and direct, "how much goods are sold, how much purchase cost is transferred" (most common)
The commercial industry (such as supermarkets, clothing stores, wholesalers) does not have a production process, and the cost is the "purchasing cost". The process is simple: incoming goods, sales and carry forward costs.
Step 1: Procurement and warehousing (purchase goods, recorded as "inventory goods")
Entry template:
Borrow: Inventory items
Taxes payable – VAT payable (input tax) (if it can be deducted)
Credit: bank deposit/accounts payable
Case: Clothing store B purchased 200 T-shirts this month, with a purchase price of 80 yuan per piece, a payment of 16,000 yuan, and a value-added tax of 2,080 yuan, which was paid with bank deposits.
Entries:
Borrow: Inventory merchandise – T-shirt 16,000
Taxes payable – VAT payable (input tax) 2080
Loan: bank deposit 18080
Step 2: Sales carry-over cost (cost calculated based on sales quantity × purchase unit price)
The key to carrying forward costs in the trade industry is to "calculate the unit price accurately." Commonly used methods include "first in, first out method" and "weighted average method" (most companies use weighted average, which is simple and not easy to make mistakes).
Weighted average unit price formula:
Weighted average unit price = (inventory cost at the beginning of the month + purchase cost this month) ÷ (inventory quantity at the beginning of the month + purchase quantity this month)
Cost of sales this month = sales quantity × weighted average unit price
Entry template:
Borrow: Main business costs
Credit: Inventory goods
Case: Clothing store B had 100 T-shirts at the beginning of the month with a cost of 70 yuan per piece (total cost 7,000 yuan). This month it purchased another 200 pieces (cost 16,000 yuan, unit price 80 yuan). A total of 250 pieces were sold this month.
Calculate the weighted average unit price: (7000+16000)÷(100+200)=23000÷300≈76.67 yuan/piece
Sales cost this month=250×76.67≈19167.5 yuan
Entries:
Borrow: Main business cost 19167.5
Credit: Inventory goods – T-shirts 19167.5
Note: Don’t worry about “rounding” fractions. In actual work, just calculate according to the system. The key point is that the method must be fixed. You cannot use weighted average this month and first-in first-out next month. The tax will think you are adjusting profits!
(3) Service industry: No “physical goods”? Labor and direct expenses are the cost!
The service industry (such as consulting companies, design companies, training institutions) sells "services" and does not have inventory goods. The costs are mainly "labor directly serving customers" and "direct expenses in the service process" (such as travel expenses for consulting projects and software fees for design).
Entry template:
Borrow: Main business costs
Credit: Employee wages payable (service staff wages)
Loan: bank deposit (direct expenses, such as travel expenses, material expenses)
Case: C Consulting Company took on a project this month. The three employees of the project team received a total salary of 40,000 yuan. They spent 5,000 yuan on travel expenses for the project, which were paid with bank deposits.
Entries:
Borrow: Main business cost 45,000
Loan: 40,000 employee compensation payable
Loan: bank deposit 5,000
Note: "Indirect expenses" such as administrative staff salaries and office water and electricity bills are not considered costs and are recorded as "management expenses"! Don't confuse them, otherwise the costs will be inflated and profits will be low.
3. The three easiest pitfalls in practice, 90% of accountants have fallen into them (with guide to avoid them)
Even if you memorize the entry template by heart, it is still easy to make mistakes in actual operation. When I first started working as an accountant, I was scolded by my master several times because of these pitfalls. Now I will share my experience with you:
Pitfall 1: Cost calculation is inaccurate, and profits follow a "roller coaster"
Common mistakes: Wrong calculation of the weighted average unit price (for example, omission of inventory at the beginning of the month), uneven distribution of production costs (for example, the cost of product A is allocated to product B).
Guide to avoid pitfalls:
Use Excel to make ledgers: inventory at the beginning of the month, purchases this month, sales quantity and amount this month are clearly listed, and the formula automatically calculates the unit price (if you don’t know how to use formulas, just search for "weighted average method Excel template", there are a lot of free ones on the Internet);
Before allocating production expenses, ask the production department to provide a "working hour statistics table". It is most reasonable to allocate according to the proportion of working hours (for example, if product A consumes 60% of the working hours, then 60% of the manufacturing expenses will be allocated).
Pitfall 2: Missing carryover or repeated carryover, inventory and accounts cannot be reconciled
Common mistakes: I was busy and forgot at the end of the month, and only made sales revenue entries without carrying forward the costs; or the system automatically carried forward once, and I did it manually again, causing the cost to double.
Guide to avoid pitfalls:
Make a "checkout checklist": list "carryover costs" as a must-do item, and tick it when done;
Check the "Detailed Inventory Account" and "Actual Warehouse Inventory" at the end of the month: If the inventory in the account is less than the actual inventory, it may be due to omission of carryover; if the inventory is more than the actual amount, it may be excessive carryover.
Pitfall 3: Wrong use of subjects, taking "other business costs" as "main business costs"
Common mistake: A company sells idle raw materials (not its main products) but records the cost as "main business costs".
Distinguishing method:
"Main business cost": the cost corresponding to the company's main income (such as the cost of selling clothes in a clothing store);
"Other business costs": costs corresponding to side business income (such as the cost of renting out excess store space for clothing stores and the cost of selling idle raw materials).
Example of entry: Selling idle raw materials cost 500 yuan
Borrow: Other business costs 500
Credit: Raw materials 500
Finally, I would like to say: It is not difficult to carry forward costs. What is difficult is "carefulness" and "matching"
In fact, you see, whether it is manufacturing, commerce or the service industry, the core of cost carryover is "matching of revenue and costs" – how much revenue is recognized this month, how much cost will be carried forward. The entry template is dead, but the actual business is alive. For example, when encountering "returns" (to offset costs, debit: inventory goods, credit: main business costs), "temporary estimation of warehousing" (estimate costs first, and then adjust after receiving invoices), you will be familiar with these special situations after doing it a few times.
It may be slow or even wrong at first, but don’t be afraid. Write down the steps mentioned today and practice step by step on the case. Within 3 months, you will definitely be able to make carryover cost entries with your eyes closed. Next time you do your billing at the end of the month, stop staring at the computer and follow this guide to make it fast and accurate!
