Think of it like peeling an onion layer by layer—the value shrinks each year as depreciation is
deducted.
Step 3: Year-by-Year Calculation
Year 2019–20
• Opening balance: ₹20,00,000 (purchased on 1st April 2019)
• Depreciation = 10% of ₹20,00,000 = ₹2,00,000
• Closing balance = ₹18,00,000
Year 2020–21
• Opening balance: ₹18,00,000
• Addition on 1st October 2020: ₹10,00,000 (used for 6 months in this year)
• Depreciation:
o On ₹18,00,000 = ₹1,80,000
o On ₹10,00,000 (6 months) = ₹50,000
• Total depreciation = ₹2,30,000
• Closing balance = ₹25,70,000
Year 2021–22
• Opening balance: ₹25,70,000
• Sale on 31st July 2021: Machinery cost ₹3,75,000
o WDV of this machine needs to be calculated:
▪ Purchased in 2019 → Depreciation for 2019–20 = ₹37,500
▪ Value at 31st March 2020 = ₹3,37,500
▪ Depreciation for 2020–21 = ₹33,750
▪ Value at 31st March 2021 = ₹3,03,750
▪ Depreciation for 4 months (April–July 2021) = ₹10,125
▪ WDV at sale = ₹2,93,625
o Sale proceeds = ₹2,75,000
o Loss on sale = ₹18,625
• Addition on 1st October 2021 = ₹5,00,000
• Depreciation:
o On remaining machinery (after sale) = ₹22,66,375 × 10% = ₹2,26,638
o On addition (6 months) = ₹25,000
o Total depreciation = ₹2,51,638
• Closing balance = ₹25,14,737
Year 2022–23
• Opening balance: ₹25,14,737
• Depreciation = 10% of ₹25,14,737 = ₹2,51,474
• Closing balance = ₹22,63,263
