(ii) Middle of each month = ₹1,200;
(iii) End of each month = ₹1,100.
The core concept here is Interest on Drawings — a charge levied by the firm on partners for withdrawing money from the business before the year-end. It compensates the firm for the temporary loss of capital. The accounting rule is simple: Interest on Drawings is a gain for the firm (credited to the Profit and Loss Appropriation Account) and a loss for the partner (debited to the Partner’s Capital Account). The journal entry is:
- Debit: Partner’s Capital Account (Menon)
- Credit: Interest on Drawings Account (which is then transferred to the Profit and Loss Appropriation Account)
The tricky part is the time period for which interest is charged. Since drawings are made monthly, the average period for which the money is used by the partner depends on when in the month the withdrawal occurs. The formula for total interest on monthly drawings of equal amount is:
Total Interest = Total Drawings × Rate × (Average Period / 12)
Where the Average Period (in months) is:
- Beginning of each month: 6.5 months (because the first withdrawal is used for 12 months, the last for 1 month; average = (12+1)/2 = 6.5)
- Middle of each month: 6 months (average = (11.5+0.5)/2 = 6)
- End of each month: 5.5 months (average = (11+0)/2 = 5.5)
Let’s apply this to Menon’s case. His monthly drawing is ₹2,000, so total drawings for the year = ₹2,000 × 12 = ₹24,000. Rate = 10% p.a.
Working Notes
Case (i): Beginning of every month
Average period = 6.5 months
Interest = 24,000 × 10/100 × 6.5/12
= 24,000 × 0.10 × 0.54167
= 24,000 × 0.054167
= ₹1,300
Case (ii): Middle of every month
Average period = 6 months
Interest = 24,000 × 10/100 × 6/12
= 24,000 × 0.10 × 0.5
= ₹1,200
Case (iii): End of every month
Average period = 5.5 months
Interest = 24,000 × 10/100 × 5.5/12
= 24,000 × 0.10 × 0.45833
= ₹1,100
A common mistake is to use the wrong average period. For beginning of month, students often mistakenly use 6 months (as if it were middle). Remember: beginning-of-month drawings are used for a longer average time, so interest is higher. End-of-month drawings are used for the shortest average time, so interest is lowest.
You can also calculate interest on each month’s drawing individually and sum them — it’s longer but foolproof. For example, for beginning-of-month: Jan drawing used for 12 months → interest = 2,000 × 10% × 12/12 = ₹200; Feb drawing used for 11 months → 2,000 × 10% × 11/12 = ₹183.33; … Dec drawing used for 1 month → ₹16.67. Sum = ₹1,300. The average-period formula is a shortcut that works only when all monthly drawings are equal.
