Nine questions on the cost principle, the matching principle and depreciation,
then two entries for a box of supplies and five years of GPUs to depreciate.
Fall 2026
Cost principle
A company pays cash for equipment it will use for the next several years. Under the cost principle, which statement is correct?
A. Paying for equipment is not an expense: the company has traded cash for a resource it will use for years, so it is an asset, and the cost principle records it at acquisition cost. Market value (B, D) and residual value (E) play no part in the initial record. The expense comes later, one year at a time, as depreciation.
Matching principle
Under the matching principle, which question decides the period in which an expense is recognized?
B. Every expenditure raises two separate questions: when is the cash paid, and when is the resource used up? Only the second one fixes the expense. Cash can leave before, after or in the same period, and it changes nothing (A). Delivery (E) is when an asset is recognized, not an expense.
Depreciation
What is depreciation?
B. Depreciation allocates cost; it does not measure value. The cost paid at purchase is spread over the years the asset is used, so each year carries its share. No cash is set aside (C), and recording an expenditure as an asset (E) is capitalization, the step that comes before depreciation.
Carrying value
The carrying value (book value) of equipment reported on the balance sheet equals which of the following?
B. Carrying value is the value of the asset reported on the balance sheet. The asset itself stays at acquisition cost, and everything depreciated so far, accumulated depreciation, is subtracted from it. Subtracting only this year’s expense (C) forgets the earlier years.
Depreciation expense
Which statement about Depreciation Expense is correct?
A. Depreciation Expense is this period’s share of the asset’s cost, and like every expense it is reported on the income statement. B and C describe Accumulated Depreciation. No cash moves when depreciation is recorded (D), and the expense repeats in every year of the useful life (E).
Accumulated depreciation
A machine is in its third year of use. At the end of Year 3, the balance of Accumulated Depreciation equals which of the following?
B. Accumulated Depreciation is the total depreciation expense recorded against the asset since it was acquired, so it grows by one year’s expense every year and is never reset (E). What is left after subtracting it from cost is the carrying value (C), a different number.
Contra asset account
Accumulated Depreciation is a contra asset account (xA). Which statement about it is correct?
A. A contra asset is used to reduce the value of an asset, so it sits in the asset section of the balance sheet but works in the opposite direction: it is credited to increase. That is why the depreciation entry credits Accumulated Depreciation (+xA, −A). Each year’s entry makes it bigger, not smaller (E).
Cost principle · acquisition cost
Cedar Mill Bakery bought a commercial oven. It paid $24,000 for the oven, $1,500 to have it delivered, and $2,500 to have it installed and tested. During the oven’s first month it also paid $600 for the electricity to run it. At what amount is the oven recorded as an asset?
D. Acquisition cost includes every cost needed to acquire the oven and prepare it for its intended use: $24,000 + $1,500 + $2,500 = $28,000. The $600 of electricity was used up running the oven that month, so it is an expense of that month, not part of the asset.
OPEX vs CAPEX
Cedar Mill Bakery made the five expenditures below. Which one is an operating expenditure (OPEX), expensed immediately rather than capitalized?
D. This month’s wages were used up generating this month’s revenue, so they are expensed immediately. The other four buy something that will generate revenue in future periods, a van, a building, two years of insurance coverage, display cases, so each is capitalized as an asset and expensed over the periods it serves.
Q10 · January — Supplies bought
Birch Lane Dental paid $3,000 cash for dental supplies on January 10 and used all of them during February. Record the January 10 purchase.
Account choices
| Account | Debit | Credit |
|---|---|---|
| 8. Supplies (+A) | 3,000 | |
| 3. Cash (−A) | 3,000 |
8, then 3. In January the supplies are still on the shelf, so nothing has been used up and there is no expense yet. The company traded one asset for another: Supplies goes up and Cash goes down. The cost principle puts the supplies on the books at what was paid, $3,000.
Q11 · February — Supplies used up
Birch Lane Dental paid $3,000 cash for dental supplies on January 10 and used all of them during February. Record the entry required at the end of February.
Account choices
| Account | Debit | Credit |
|---|---|---|
| 9. Supplies Expense (+E, −SHE) | 3,000 | |
| 8. Supplies (−A) | 3,000 |
9, then 8. February is when the supplies were used up, so February carries the $3,000 expense. Supplies Expense is debited and the asset Supplies is credited down to zero. No cash moves in February; it left in January, and that is not what the expense follows.
Q12–Q18 · Quartz Analytics buys GPUs
On January 1, Year 1, Quartz Analytics, Inc. paid NVIDIA $10,000,000 cash for GPUs it will use for five years, with no residual value. Depreciation is distributed equally over the five years, and financial statements are prepared each December 31. Fill in each amount as a whole number of millions.
10, 2, 2, 2, 4, 8, 6. The GPUs go on the books at the $10M paid. Each year takes an equal $2M slice as Depreciation Expense; Accumulated Depreciation adds the slices up ($2M, then $4M); carrying value is what is left ($10M − $2M = $8M, then $10M − $4M = $6M).
Q19 · December 31, Year 1 — Depreciation
Quartz Analytics bought the GPUs for $10,000,000 on January 1, Year 1; they have a five-year life, no residual value, and depreciation is distributed equally. Record the depreciation for Year 1 on December 31, Year 1.
Account choices
| Account | Debit | Credit |
|---|---|---|
| 4. Depreciation Expense (+E, −SHE) | 2,000,000 | |
| 2. Accumulated Depreciation (+xA, −A) | 2,000,000 |
4, then 2. One year of the GPUs has been used up, so Year 1 carries $2M of Depreciation Expense. The credit goes to Accumulated Depreciation, not to Equipment: the GPUs stay on the books at their $10M cost, and the contra asset beside them records how much of it has been used. No cash moves; it all left on January 1.
Q20 · December 31, Year 2 — Depreciation
Quartz Analytics bought the GPUs for $10,000,000 on January 1, Year 1; they have a five-year life, no residual value, and depreciation is distributed equally. Record the depreciation for Year 2 on December 31, Year 2.
Account choices
| Account | Debit | Credit |
|---|---|---|
| 4. Depreciation Expense (+E, −SHE) | 2,000,000 | |
| 2. Accumulated Depreciation (+xA, −A) | 2,000,000 |
4, then 2. The same entry as Year 1, for the same $2M: the slice is equal every year. What changes is the balance it lands in. Accumulated Depreciation now holds $4M, so the carrying value is $10M − $4M = $6M, while Equipment itself has not moved.
An asset is recorded at its acquisition cost: everything paid to acquire it and prepare it for its intended use.
An expense is recognized in the period the resource is used up, whatever the cash does.
Depreciation Expense is one year’s share of the cost; Accumulated Depreciation is every year’s share so far; carrying value is cost less accumulated depreciation.
