Own rate of interest

3 key takeaways:

• The own rate of interest reflects the return on an asset, accounting for its income generation and holding costs.
• It is used to compare the attractiveness of different assets, guiding investment decisions.
• This rate incorporates factors such as dividends, rental income, storage costs, and depreciation.

What is the own rate of interest?

The own rate of interest, also known as the rate of return, is a measure of the profitability of holding a particular asset. It takes into account the income generated by the asset, such as dividends or rental income, as well as any costs associated with owning the asset, like storage or maintenance costs. This concept helps investors assess the relative attractiveness of various assets by comparing their respective own rates of interest.

For example, an investor might compare the own rate of interest of a rental property (considering rental income and maintenance costs) with that of a stock (considering dividends and price appreciation) to decide where to allocate funds.

Components of the own rate of interest

• Income generation: Includes dividends, interest payments, rental income, or any other returns produced by the asset.
• Holding costs: Expenses related to maintaining the asset, such as storage costs, insurance, maintenance, and depreciation.
• Capital appreciation or depreciation: The increase or decrease in the asset’s value over time.

For instance, a bond’s own rate of interest would include the coupon payments (income generation) and account for any costs related to purchasing or holding the bond.

Importance of the own rate of interest

• Investment comparison: It allows investors to compare the profitability of different assets, helping them make informed investment decisions.
• Resource allocation: By understanding the own rate of interest, investors can allocate resources to assets that offer the best return relative to their costs.
• Risk assessment: Evaluating the own rate of interest helps in assessing the risk-return profile of an asset, guiding risk management strategies.

For example, an investor might find that the own rate of interest for a high-dividend stock is more attractive than that for a government bond, influencing their investment choice.

Calculation of the own rate of interest

To calculate the own rate of interest, consider the following formula:

[ \text{Own Rate of Interest} = \frac{\text{Income Generation} – \text{Holding Costs}}{\text{Asset Value}} ]

For example, if a rental property generates $10,000 in rental income annually, has $2,000 in maintenance costs, and is valued at $200,000, the own rate of interest would be:

[ \text{Own Rate of Interest} = \frac{10,000 – 2,000}{200,000} = \frac{8,000}{200,000} = 0.04 \text{ or } 4\% ]

Examples of own rate of interest in different assets

• Real estate: Rental income minus maintenance and property management costs, divided by the property value.
• Stocks: Dividends received, adjusted for any trading costs or taxes, divided by the stock price.
• Bonds: Coupon payments minus any costs of holding the bond, divided by the bond’s market value.
• Commodities: Potential income from leasing the commodity (if applicable) minus storage costs, divided by the commodity’s value.

For example, the own rate of interest for a stock might be calculated based on the annual dividends it pays, adjusted for any transaction fees or taxes, relative to its current market price.
