Question

When a company uses financial leveraging, are the investors using their own money?

Answer 1

The Straight answer is NO.

In simple words using financial leverage means using borrowed money to control a greater amount of assets.

With financial leverage there will be an increase in the value of the assets that will result in a larger gain on the owner's cash, when the loan interest rate is less than the rate of increase in the asset's value.

Examples of Financial Leverage
Mary uses $500,000 of her cash to purchase 40 acres of land with a total cost of $500,000. Mary is not using financial leverage.

Sue uses $500,000 of her cash and borrows $1,000,000 to purchase 120 acres of land having a total cost of $1,500,000. Sue is using financial leverage to own/control $1,500,000 of property with only $500,000 of her own money. Let's also assume that the interest on Sue's loan is $50,000 per year and it is paid at the beginning of each year.

Effects of Using Financial Leverage
For our examples let's assume that after one year, the land owned by Mary and the land owned by Sue increased in value by 20% and both Mary and Sue sold their land investments at the market values. As a result:

Mary's land will sell for $600,000 which results in a gain of $100,000 (selling price of $600,000 minus the land's cost of $500,000). The $100,000 gain on Mary's cash of $500,000 results in a gain of 20% on Mary's $100,000
Sue's land will sell for $1,800,000 which results in a gain of $250,000 (selling price of $1,800,000 minus $1,550,000, which is the land's cost of $1,500,000 and interest of $50,000). The $250,000 gain on Sue's $550,000 of cash is a gain of 45% instead of a gain of 20% without the use of leverage
Now let's assume that after one year, the land owned by Mary and and the land owned by Sue decreased in value by 20% and that both Mary and Sue sold their land investments at the market values. As a result:

Mary's land will sell for $400,000 which means a $100,000 loss on the land's cost of $500,000. The $100,000 loss on Mary's cash of $500,000 results in a 20% loss on Mary's money
Sue's land will sell for $1,200,000 which results in a loss of $350,000 (selling price of $1,200,000 minus the land's cost of $1,500,000 and interest of $50,000). The $350,000 loss on Sue's cash of $550,000 results in a 63.6% loss on Sue's money instead of a loss of 20% without the use of leverage.
