Gross Interest

What Is Gross Interest?

Gross interest is the annual rate of interest to be paid on an investment, security, or deposit account before taxes or other charges are deducted. Gross interest is often the headline interest rate attached to a fixed-income security (e.g., a bond or CD), a loan, or a deposit account.

Gross interest is expressed as a percentage and can be contrasted with net interest, which is the rate of interest earned after taxes, fees, and other costs are deducted. As a result, gross interest will always be higher than net interest.

Key Takeaways

  • Gross interest is the headline interest rate earned on a fixed-income investment or paid on a loan before fees or taxes are accounted for.
  • The gross interest rate is what is more often quoted for a loan or investment.
  • Net interest deducts the impact of taxes, fees, and other costs from the gross interest. For instance, a gross 5% interest earned on deposits and taxed at 25% would result in 3.75% net interest.

Understanding Gross Interest

When an individual deposits money in their bank account, the bank pays interest on the funds to the account holder in compensation for the deposit. This is because the deposit is used to lend money to other individual and corporate borrowers, generating income for the bank. The interest paid to the account holder may be deposited in the entity’s account monthly, quarterly, or annually, depending on the financial institution or type of account.

The interest is simply referred to as gross interest because it does not factor in taxes, which also impacts the interest earnings. For example, if you have $3,000 in a savings account that earns 2% interest paid on a yearly basis, the quoted 2% is the gross interest. So the bank would pay you $60 at the end of the year.

However, the gross interest does not take into account other items such as taxes, fees, and other charges that may apply to the investment or account. After these costs are taken into account and deducted from the gross interest earned, the account holder actually walks away with less. Following from our example above, if the annual fee on the savings account is $5 and you were taxed 35%, taxes due would be $21 (calculated by multiplying $60 by 35%) and the net interest earned would be calculated as $60 - $21 - $5 = $34, or 1.13%, which is less than the 2% gross interest.

Gross interest is always higher than net interest.

Gross Interest and Bonds

Gross interest is simply the pure interest amount paid by a debtor to a creditor. For bonds, the quoted interest income bondholders receive from their investment represents gross interest. Assume, for example, that a bond investor purchases a $1,000 par value corporate bond with a coupon rate of 3% payable annually and a maturity date of five years. The bond issuer will periodically pay the bondholder a fixed interest of 3% x $1,000 = $30 for the duration of the bond’s life. The fixed coupon rate is the gross interest. However, at the end of the year, the interest earned on the corporate bond will be taxed by the government. Therefore, the bondholder’s effective net yield will be less than 3%.

The net interest is calculated from the gross interest after other fees and costs are deducted.
