Sarah's interview: TechStart is expanding and needs new equipment. Why can't she just expense it?
Sarah Needs New Equipment — But How Should She Track It?
TechStart Solutions is growing. Sarah wants to buy a $15,000 commercial 3D printer. It seems simple — buy the printer, record the cost, done. But an investor is watching, and how Sarah handles this purchase will signal whether she understands professional financial management. The question is not just "Can we afford it?" — it is "How do we track this cost over time?"
When a business buys something small — like printer paper or coffee for the office — it records the cost as an expense right away. The item is used up quickly. But when a business buys something big that lasts for years — like equipment, vehicles, or buildings — the rules change. The cost cannot be expensed all at once. It must be tracked as an assetand its cost spread across the years it provides value. This process is called depreciation.
The enduring formula for this unit: Book Value = Cost - Accumulated Depreciation
Every lesson in this unit connects back to this formula. By the end, you will understand what each term means, how to calculate it, and why investors care.
TechStart Solutions is growing. Sarah needs to buy a $15,000 commercial 3D printer for her product line. But how should she track this cost? Can she expense it all at once, or does it need to be tracked differently? An investor is watching how she handles this decision.
Duration: 4:30
Throughout this unit, you will track three numbers for every long-term asset:
Cost
What you paid for the asset, including delivery and installation. For Sarah's printer: $15,000.
Accumulated Depreciation
The total amount of the asset's cost that has been "used up" so far. This grows each year.
Book Value
What the asset is still worth on the company's books. Book Value = Cost - Accumulated Depreciation.
1. Why can't Sarah just expense the entire $15,000 printer purchase in the month she buys it?
2. What is the core formula for tracking an asset's value over time?
3. Why would an investor care about how Sarah tracks her equipment purchase?
Discussion Prompt (3 minutes):
Imagine you bought a $1,200 laptop for your business. It will last 4 years.
- Would it be fair to record the entire $1,200 as an expense in month 1?
- What would your profit look like in month 1 vs. month 12 if you did?
- How much of the laptop's cost should "count" against each year's profit?
Now that you understand the problem — long-term assets cannot be expensed all at once — the next lesson will teach you the rules for deciding when a cost becomes an asset (capitalization) and how to estimate how long it will last (useful life) and what it will be worth at the end (salvage value). You will also learn how accumulated depreciation builds up over time and why it matters for both the income statement and the balance sheet.
