Is the Interest on the Capital GL Account debit or credit to the journal entry?
Interest on Capital, being an expense GL, is a Nominal Account. Per Nominal A/c Golden rules of accounting, “Debit all Expenses and Loss, and Credit all Incomes and Gains”. Therefore, we must debit the Interest on Capital in the journal entry.
What does Capital mean?
Capital is the initial sum that owners bring into the business. Capital is a liability to the company because its general practice is to consider the business separate from its owner.
Partners bring in Capital either through Cash/Bank or in the form of assets.
For example, partners may introduce a personal car or bring cash into the business. These are nothing but capital contributions.
If the Partner brings Capital in the form of assets, then the equivalent value of such assets will be the Capital investment recorded in the books of accounts.
What’s the reason for charging interest on Capital investment?
The owner invests his/her hard-earned money in a business with the expectation of earning some profits or receiving an inflow of cashback. Therefore, partners hope to get some return on the investments.

Therefore, Interest is introduced. It’s a mandatory charge against the current year’s income.
Summary of the reasoning:
Profits are the residual amounts remaining after deducting expenses. However, interest is charged against income. Therefore, interest expense is always a priority payment to the owner compared to profits.
