Reflect on what the comparison workbook added, name what you can now do faster, and preview the project rehearsal
Today you extended your asset register workbook with a Method Comparison sheet that shows straight-line and double-declining balance side by side. You built verification checks so accumulated depreciation and book value stay believable. And you practiced defending a depreciation recommendation with workbook evidence — not opinion.
Key Takeaways
- Both methods depreciate the same total amount — only the timing differs
- DDB front-loads expense — higher Year 1 expense, lower reported profit, lower book value early on
- The salvage value floor is non-negotiable — DDB must never drive book value below salvage
- Linked formulas beat hard-coded numbers — if cost changes, your comparison updates automatically
- A professional recommendation uses evidence — cite workbook numbers, not feelings
What's Next
In Lesson 07, you will rehearse the complete depreciation project with a shared dataset. You will practice the full workflow: asset register → depreciation schedule → method comparison → recommendation. This lesson's comparison workbook is one piece of that larger project structure.
