Q.Raj and Neeraj are partners in a firm. Their capitals as on April 01, 20 19 were Rs. 2,50,000 and Rs. 1,50,000, respectively. They share profits equally. On July 01, 20 19, they decided that their capitals should be Rs. 1,00,000 each. The necessary adjustment in the capitals were made by introducing or withdrawing cash by the partners'. Interest on capital is allowed @ 8% p.a. Compute interest on capital for both the partners for the year ending on March 31, 2020.

Raj's interest on capital is ₹11,000 and Neeraj's interest on capital is ₹9,000 for the year ending March 31, 2020, calculated on their fluctuating capitals after the July 1 adjustment.

The key concept here is that interest on capital is calculated on the capital that actually remained in the business for the specific period it was available. When partners change their capital amounts during the year, you cannot simply take the opening balance and apply the full year's rate. You must split the year into periods before and after the change, compute interest for each period separately, and then add them up.

Raj and Neeraj share profits equally, but that ratio is irrelevant for interest on capital — interest is always computed on each partner's individual capital balance, not on the profit-sharing ratio.

The treatment follows the Partnership Deed (or the default rule under the Indian Partnership Act, 1932, if the deed is silent). Since the problem explicitly states "Interest on capital is allowed @ 8% p.a.", it is a charge against profits (an appropriation), meaning it is calculated regardless of whether the firm earns a profit or loss. The capitals here are fluctuating (not fixed), because the partners introduced or withdrew cash to adjust their capitals to ₹1,00,000 each on July 1, 2019.

Let us break down the periods:

Period 1: April 1, 2019 to June 30, 2019 (3 months) — capitals are at their original amounts.

Period 2: July 1, 2019 to March 31, 2020 (9 months) — capitals are at the adjusted amount of ₹1,00,000 each.

Now, we compute interest for each partner separately.

Working Notes

Working Note 1: Interest on Raj's Capital

  • Period 1 (3 months): Capital = ₹2,50,000. Interest = 2,50,000 × 8/100 × 3/12 = 2,50,000 × 0.08 × 0.25 = ₹5,000.
  • Period 2 (9 months): Capital = ₹1,00,000. Interest = 1,00,000 × 8/100 × 9/12 = 1,00,000 × 0.08 × 0.75 = ₹6,000.
  • Total Interest for Raj: ₹5,000 + ₹6,000 = ₹11,000.

Working Note 2: Interest on Neeraj's Capital

  • Period 1 (3 months): Capital = ₹1,50,000. Interest = 1,50,000 × 8/100 × 3/12 = 1,50,000 × 0.08 × 0.25 = ₹3,000.
  • Period 2 (9 months): Capital = ₹1,00,000. Interest = 1,00,000 × 8/100 × 9/12 = 1,00,000 × 0.08 × 0.75 = ₹6,000.
  • Total Interest for Neeraj: ₹3,000 + ₹6,000 = ₹9,000.
Watch out

A common mistake is to calculate interest on the opening capital for the full year (e.g., Raj: 2,50,000 × 8% = ₹20,000) and then adjust for the withdrawal. That is incorrect because the capital changed mid-year. You must treat each period's capital as a separate principal amount.

Tip

A shortcut: For each partner, compute interest as: (Old Capital × Rate × Old Period) + (New Capital × Rate × New Period). Always express the period as a fraction of the year.

Solution: Journal Entry for Interest on Capital

The journal entry to record interest on capital is:

DateParticularsL.F.Debit (₹)Credit (₹)
March 31, 2020Interest on Capital A/c Dr.20,000
To Raj's Capital A/c11,000
To Neeraj's Capital A/c9,000
(Interest on capital allowed @ 8% p.a. for the year)

Explanation: Interest on Capital is an expense (appropriation) for the firm, so it is debited. It is a gain for each partner, so their capital accounts are credited. …
