How many years it will take you to double your money if you invest $500 at an interest rate of 8% per year?
For example, if an investment scheme promises an 8% annual compounded rate of return, it will take approximately nine years (72 / 8 = 9) to double the invested money.
Answer and Explanation:
The answer is 14.21 years. This is a future value (FV) problem that asks for the time necessary to double the PV of an initial investment of $500, given a simple annual interest rate of 5%. Using the variables provided, the problem is stated and solved algebraically, as illustrated below.
To get the answer, divide 72 by 4, so it would take 18 years to double your money. If you have $500 and wanted to double your money in 10 years, how much interest would have to earn? The answer that, divide 72 by 10. The result, 7.2, tells you need a 7.2% APY to double your money in 10 years.
The Basics
Let's say your interest rate is 8%. 72 ∕ 8 = 9, so it will take about 9 years to double your money. A 10% interest rate will double your investment in about 7 years (72 ∕ 10 = 7.2); an amount invested at a 12% interest rate will double in about 6 years (72 ∕ 12 = 6).
Answer and Explanation:
Since interest is compounded quarterly we first estimate the number of quarters then convert to years. The investment will be doubled in 8 years and 274 days.
We will use the Rule of 72 to find the approximate number of years to double this investment: Years = 72 / Percent interest rate. Years = 72 / 4. Years = 18.
For example, if an investment scheme promises an 8% annual compounded rate of return, it will take approximately nine years (72 / 8 = 9) to double the invested money. Note that a compound annual return of 8% is plugged into this equation as 8, and not 0.08, giving a result of nine years (and not 900).
| Rate of return | 10 years | 30 years |
|---|---|---|
| 4% | $72,000 | $336,500 |
| 6% | $79,000 | $474,300 |
| 8% | $86,900 | $679,700 |
| 10% | $95,600 | $987,000 |
at 8% simple interest it will take 12.5 months to get doubled. at 5% simple interest it will take 20 months to get doubled. that is the difference of 7.5 months. Therefore, A $600 investment double at an 8% interest rate 7.5 months quicker as compared to a 5% interest rate.

Will my money double in 10 years?
Similarly, if you want to double your money in five years, your investments will need to grow at around 14.4% per year (72/5). If your goal is to double your invested sum in 10 years, you should invest in a manner to earn around 7% every year. Rule of 72 provides an approximate idea and assumes one time investment.
Money experts say that if one remains invested in a disciplined way, in the long run, mutual funds can give around 12-15% returns.So, an investment of ₹1 lakh in MFs will double ( ₹2 lakh) in six years assuming a 12% interest rate.
A well-constructed dividend portfolio could potentially yield anywhere from 2% to 8% per year. This means, to earn $3,000 monthly from dividend stocks, the required initial investment could range from $450,000 to $1.8 million, depending on the yield. Furthermore, potential capital gains can add to your total returns.
The truth is that most investors won't have the money to generate $1,000 per month in dividends; not at first, anyway. Even if you find a market-beating series of investments that average 3% annual yield, you would still need $400,000 in up-front capital to hit your targets. And that's okay.
Now, let's consider how our calculations change if the time horizon is 10 years. If you are starting from scratch, you will need to invest about $4,757 at the end of every month for 10 years. Suppose you already have $100,000. Then you will only need $3,390 at the end of every month to become a millionaire in 10 years.
