Unit 8 • Lesson 20.8h

When Does a Cost Become an Asset? — Capitalization, Useful Life, and Salvage Value

Lesson 02 teaches the rules for deciding when a cost becomes a long-term asset (capitalization) versus an immediate expense. Students learn to estimate useful life and salvage value, calculate the depreciable base, and understand how accumulated depreciation builds. This is the foundation for all depreciation methods covered in Lessons 03 and 04.

What You'll Learn
  • Decide whether a purchase should be capitalized as an asset or expensed immediately
  • Estimate useful life and salvage value for common business assets
  • Calculate the depreciable base (Cost - Salvage Value) for an asset
  • Explain how accumulated depreciation builds over time
Key Concepts
Capitalization vs. expense — the matching principle in action
Useful life: how long an asset provides value
Salvage value: what the asset is worth at the end

Lesson Phases

This lesson follows a structured 6-phase learning model designed for authentic project-based learning.

Hook

Reconnect to Lesson 01's equipment purchase. Sarah needs to classify three new purchases — which are assets and which are expenses?

Start Phase

Introduction

Explicit instruction: capitalization rules, useful life, salvage value, and depreciable base with worked examples.

Start Phase

Guided Practice

Mixed purchase scenarios with reduced scaffolding. Students classify and explain choices, not just compute.

Start Phase

Independent Practice

Algorithmic deliberate practice: classify purchases as capitalize or expense with streak tracking and reteach guidance.

Start Phase

Assessment

Short MCQ exit ticket on capitalization vocabulary, useful life, salvage value, and reasoning.

Start Phase

Closing

Reflect on confidence and understanding. Connect to the business problem. Preview straight-line depreciation.
