Compounding can have a dramatic effect on your wealth over time. The longer your time horizon, the larger the impact. <\/p>\n\n\n\n
This is best illustrated with a quick example. Let\u2019s say you\u2019re saving for retirement and save $500 each month. The table below shows how much your savings would grow over time, taking into account the impact of a 5% annual return and monthly compounding.<\/p>\n\n\n\n As you can see, the earlier you start taking advantage of compounding, the more you benefit.\u00a0 If you save $500 a month for 30 years, you\u2019ll have $416,129.32 by retirement, $236,129.32 of which is earnings. Starting earlier is even better: if you save $500 each month for 40 years, by the time you retire you\u2019ll have a staggering $763,010.08, over half a million of which ($523,010.08) is earnings. As this example demonstrates, compounding is a powerful way of growing your savings faster over time.<\/p>\n\n\n\n Compound interest is the interest you earn on your original investment plus the interest you earn on your interest. You can earn compound interest in an interest-bearing account like the Wealthfront Cash Account<\/a> or on a bond.<\/p>\n\n\n\n Interest can compound (or get added to your original deposit and start earning interest itself) on different schedules\u2014daily, monthly, etc. The more frequently your interest compounds, the more interest you\u2019ll earn.<\/p>\n\n\n\n Most interest-bearing accounts pay compound interest, but there\u2019s a second kind of interest you should understand: simple interest. When you earn simple interest, your interest doesn\u2019t earn interest. The easiest way to see the difference between simple and compound interest is with an example. <\/p>\n\n\n\n Let\u2019s say you put $1,000 into an account with 5% simple interest. After 50 years, your $1,000 earning 5% interest would be worth $3,500. But if you earned compound interest (assuming monthly compounding), it would be worth $12,119.38 after 50 years\u2014over three times as much.\u00a0<\/p>\n\n\n\n Value of $1,000 over 50 years with 5% interest<\/strong><\/p>\n\n\n\n The table below shows you how to calculate compound interest, assuming you don\u2019t make any add-on deposits or withdrawals. Just plug in the principal (that\u2019s your starting amount, designated with a \u201cp\u201d), annual interest rate (\u201ci\u201d), and time horizon (\u201cn\u201d is number of years).\u00a0<\/p>\n\n\n\n There are also many online calculators you can use to do the math, like this one from Investor.gov<\/a>.<\/p>\n\n\n\n The obvious benefit of compound interest is that it helps your savings grow faster. But when you owe someone money and you\u2019re paying compound interest on the loan, compounding works against you. Credit card debt, for example, often compounds daily. The good news is that two common kinds of debt, mortgages and student loans, generally have simple interest.\u00a0<\/p>\n\n\n\n If you invest using a taxable investment account like a Wealthfront Investment Account<\/a> or a retirement account like a Wealthfront IRA<\/a>, you can earn compound returns. You probably already know that when you buy an investment (like a stock, bond, or index fund) and the value of that investment increases, you earn returns. You may not know that these returns compound over time in much the same way that compound interest does, as long as you leave your earnings invested. However, unlike interest that compounds on a set schedule, investment returns generally compound continuously. You can calculate the impact of continuous compounding using the formula below:<\/p>\n\n\n\n The \u201crule of 72\u201d is a rule of thumb that helps you calculate how long it will take your investment to double in value, taking into account the impact of compounding and assuming you don\u2019t add to your investment. Just take the number 72 and divide it by your annual return (expressed as a percentage). The resulting number tells you roughly how many years it will take your investment to be worth twice as much.<\/p>\n\n\n\n For example, let\u2019s say you expect your investment to have a 8% rate of return each year. 72 divided by 8 is 9. Your investment will take about 9 years to double in value.\u00a0<\/p>\n\n\n\n Intuitively, you probably know it\u2019s better for someone to give you\u00a0$100 today than $100 in five years (even ignoring the impact of inflation<\/a>). That\u2019s because if someone gives you $100 today, you can invest it so it\u2019s worth more in the future. This concept is known as the time value of money. But what if someone offers you $100 now or $120 in five years?\u00a0<\/p>\n\n\n\n You can use the formula below to calculate what a sum of money today will be worth in the future if you invest it, taking into account the impact of continuous compounding.\u00a0<\/p>\n\n\n\n In the case of the example above, if you could earn an 8% annual rate of return for those five years, you\u2019d much rather have $100 today because its future value is $149.18.\u00a0<\/p>\n\n\n\n If you\u2019re building wealth, compounding works to your advantage. Just start saving (or investing) as early as possible so you can give your money the maximum amount of time to grow.<\/strong> You can earn compound interest in a Wealthfront Cash Account<\/a>, or let your investment returns compound in a Wealthfront Investment Account<\/a> (or Wealthfront IRA<\/a>, if you\u2019re saving for retirement). When you invest with Wealthfront, we automatically reinvest your dividends so those earnings will compound without any extra effort.\u00a0<\/p>\n","protected":false},"excerpt":{"rendered":" When you\u2019re building long-term wealth, compounding can help you get there faster by increasing the rate at which your money grows.
