Compounding can be a powerful engine for account growth

When you deposit money in a bank account, the bank promises to periodically pay you a certain percentage of that money in exchange for letting it use the money you deposited. The money the bank pays you is called “interest.” Compound interest is the interest you earn on interest you’ve already been paid.

Consider this illustration: If you deposit $1,000 in a bank account paying 5% interest each year, you’ll have $1,050 at the end of the first year. Assuming you keep your money and the interest you earned in your account, you’ll have $1,102.50 at the end of the second year. At the end of the third year, you’ll have $1,157.62. And so on.

Compounding adds up 

In this example, an investor invests $1,000 today earning 8% interest annually. With simple interest, an investor would have $3,400 at the end of 30 years. With compounding, an investor would have over $10,000.

How it works in your retirement account

When you contribute to your retirement account, you allocate that money to be invested in various options available through the plan. Those options may include mutual funds, stable value funds and fixed interest accounts.

For this example, let’s assume you’ve allocated your assets to a mutual fund, an investment vehicle that pools money from many investors and invests it in securities such as stocks and bonds.

  • Stocks are shares of ownership in a corporation that entitles the owner to a proportion of its assets and profits. Those earnings are typically paid as dividends.
  • Bonds are essentially loans issued by governments and corporations, which agree to regularly pay interest.

The dividends and interest that the mutual fund receives from the stocks and bonds it holds are used to pay returns to investors. These returns are reinvested in the fund for as long as the investor holds it, allowing the returns to compound each time earnings are paid.

This process of compounded earnings, repeated with each asset you invest in, could help you significantly grow your retirement account over the long term. Bear in mind, however, that all investing is subject to risk. No investment strategy, including compounding, can ensure a profit or protect against a loss, especially in a down market.
