How many years will it take to double $100 at an interest rate of 10?
In summary, at an annual interest rate of 10 percent, it will take approximately 7.2 years for $100 to double in value. However, it is important to remember that this is only an estimate and may not be entirely accurate due to various factors that can impact investment growth.
How the Rule of 72 Works. For example, the Rule of 72 states that $1 invested at an annual fixed interest rate of 10% would take 7.2 years ((72/10) = 7.2) to grow to $2. In reality, a 10% investment will take 7.3 years to double (1.107.3 = 2).
If you were to gain 10% annual interest on $100, for example, the total amount earned per year would be $10. At the end of the year, you'd have $110: the initial $100, plus $10 of interest.
If you earn 7%, your money will double in a little over 10 years. You can also use the Rule of 72 to plug in interest rates from credit card debt, a car loan, home mortgage, or student loan to figure out how many years it'll take your money to double for someone else.
Rule of 72
Simply divide the number 72 by the annual rate of return to determine how many years it will take to double. For example, $100 with a fixed rate of return of 8% will take approximately nine (72 / 8) years to grow to $200.
∴t=10 years.
The Rule of 72 is a calculation that estimates the number of years it takes to double your money at a specified rate of return. If, for example, your account earns 4 percent, divide 72 by 4 to get the number of years it will take for your money to double. In this case, 18 years.
Investing $100 per month, with an average return rate of 10%, will yield $200,000 after 30 years. Due to compound interest, your investment will yield $535,000 after 40 years. These numbers can grow exponentially with an extra $100. If you make a monthly investment of $200, your 30-year yield will be close to $400,000.

It's used to calculate the doubling time or growth rate of investment or business metrics. This helps accountants to predict how long it will take for a value to double. The rule of 69 is simple: divide 69 by the growth rate percentage. It will then tell you how many periods it'll take for the value to double.
So, if the interest rate is 6%, you would divide 72 by 6 to get 12. This means that the investment will take about 12 years to double with a 6% fixed annual interest rate. This calculator flips the 72 rule and shows what interest rate you would need to double your investment in a set number of years.
Here's a little secret: compound interest is a millionaire's best friend. It's really free money.
Interest on investment rate: 6% p.a. It would take 12 yearsto double an investment of $2,000.
The future value of $10,000 with 6 % interest after 5 years at simple interest will be $ 13,000.
Using the Rule of 72: 72÷12=6. Your money will double every six years. Because 36÷6=6, it will double six times. So, $5,000 becomes $10,000, then $20,000, then $40,000, then $80,000, then $160,000, and finally $320,000.
after 20 years $ 600 will yield an interest of double itself.
It's an easy way to calculate just how long it's going to take for your money to double. Just take the number 72 and divide it by the interest rate you hope to earn. That number gives you the approximate number of years it will take for your investment to double.
