What is the main difference between straight-line and reducing balance?

The main difference is the base for the calculation: straight-line applies a percentage to the original cost (less residual value), while reducing balance applies a percentage to the net book value.

How do I know which depreciation method to use in the exam?

The exam question will always specify which method to use for a given class of asset, for example, "The company depreciates its vehicles at 25% per annum using the reducing balance method."

What if I make a calculation error? Will I lose all the marks?

No, you will not lose all the marks. ACCA uses "own figure rule" marking, so if you show your workings, you can still earn method marks even if the initial calculation was wrong.

Why would a company choose the reducing balance method?

A company chooses this method when an asset is expected to be more productive and generate more revenue in its earlier years, so matching a higher depreciation expense against it is more appropriate.

Do I need to account for residual value with this method?

Generally, for the ACCA FA exam, you apply the percentage to the NBV without deducting residual value, as the declining charge means the NBV may never reach zero anyway.

How many hours should I spend practicing this topic?

If you are short on time, aim for focused practice. One hour of actively working through 3-4 varied examples is more effective than three hours of passively reading notes.

What happens if an asset's NBV falls below its residual value?

Depreciation should cease once the net book value of the asset reaches its estimated residual value. No further depreciation should be charged.

Am I ready for the exam if I understand this method?

Mastering this method is a great step, but readiness comes from being able to handle a range of topics under time pressure. Use this as a confidence boost and move on to practice questions covering other syllabus areas.
