Why declining balance method matters to a first-time founder
This method can match accounting expense more closely to assets that lose usefulness quickly or generate more benefit when new. It lowers reported profit more in early years and less later. The choice affects accounts and tax timing, but permitted methods vary by reporting framework and jurisdiction.
Examples of declining balance method
A machine costs ₹10 million and uses a 30% declining rate. Depreciation is ₹3 million in year one, leaving a ₹7 million book value. Year-two depreciation is ₹2.1 million, which is 30% of ₹7 million, leaving ₹4.9 million before considering the residual value limit.
Common misunderstanding
The percentage is applied to the remaining written-down value, the book value left after depreciation, not repeatedly to original cost. This differs from straight-line depreciation, which normally spreads the depreciable amount evenly. A faster accounting charge also does not prove the asset’s market price falls at the same rate.
When to use it
Consider it when an asset’s benefits or obsolescence are concentrated in earlier years and the applicable accounting rules allow it. Document the useful life, rate and residual value, then review estimates when circumstances change. Get tax advice before assuming the accounting method determines tax deductions.
