At what effective rate does money double in 9 years?

Answer. It take about 14 years for four folding in which doubling the sum of money takes place in 7 years.

A sum of money at simple interest double itself in 4 years. in how many years will it triple itself... At what rate percent per annum simple interest, will a sum of money triple itself in 25 years?

For example, if the interest rate earned is 6%, it will take 12 years (72 divided by 6) for your money to double.

The Rule of 72 indicates than an investment earning 9% per year compounded annually will double in 8 years. The rule also means if you want your money to double in 4 years, you need to find an investment that earns 18% per year compounded annually.

(72/9 = 8) If you invest at an 8% return, you will double your money every 9 years. (72/8 = 9) If you invest at a 7% return, you will double your money every 10.2 years.

If an investment scheme promises an 8% annual compounded rate of return, it will take approximately (72 / 8) = 9 years to double the invested money.

The rule states that the amount of time required to double your money can be estimated by dividing 72 by your rate of return. 1 For example: If you invest money at a 10% return, you will double your money every 7.2 years.

If you invest at a 7% return, you will double your money every 10.2 years..

approximately nine yearsFor 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.

The rule can tell you how fast you can double your money. Divide 72 by the interest rate at which you are compounding your money, and you will arrive at the number of years it will take to double in value. For instance, you money will double in 3 years if you are compounding at 24 per cent (ie 72/24 = 3 years).

 At 10%, you could double your initial investment every seven years (72 divided by 10). In a less-risky investment such as bonds, which have averaged a return of about 5% to 6% over the same time period, you could expect to double your money in about 12 years (72 divided by 6).

14.4%For example if you wanted to double an investment in 5 years, divide 72 by 5 to learn that you'll need to earn 14.4% interest annually on your investment for 5 years: 14.4 × 5 = 72. The Rule of 72 is a simplified version of the more involved compound interest calculation.

Here's how the Rule of 72 works: At 10%, money doubles every 7.2 years and when you divide 7.2 by 10%, you get 72. This rule of thumb helps you compute when your money (or any unit of numbers) will double at a given interest (growth) rate.

9% per yearThe Rule of 72 indicates than an investment earning 9% per year compounded annually will double in 8 years.

Question: At What Nominal Rate Compounded Continuously Must Money Be Invested To Triple In 4 Years? A Rate Of % Is Required For Money To Triple In 4 Years.

Answer. ☆☆☆Let the rate percent per annum be R. Thus, the required rate is 25.99% per annum.

Hence, if we have 2x after 7 years, we'll get its double after the same amount of time (4x at t = 14).

Hope it's clear..

In how many years will a sum of money double itself with the rate of 10% per annum simple interest? Here, we have R = 10% and have to calculate t for the sum of the money (that is P) to double. Hence, it will take 10 years for the sum of money to double itself with the rate of 10% per annum simple interest.

14.4% per yearSimilarly, 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.

Answer Expert Verified At 5% simple interest, a sum of money doubles itself in 20 years..

Answer. R =? At 5% simple interest, a sum of money doubles itself in 20 years.

Answer Expert Verified At 5% simple interest, a sum of money doubles itself in 20 years.

If the sum doubles (x2) in 15 years, then it to become 2*2*2 = 8 times as large it should double three times, so three 15 years time period are needed, which is 3*15 = 45 years.

10% per annumAnswer. it means at the rate of 10% per annum sum will double itself in 10 years .

Here, we have R = 10% and have to calculate t for the sum of the money (that is P) to double. Hence, it will take 10 years for the sum of money to double itself with the rate of 10% per annum simple interest.

10% per annumAnswer. it means at the rate of 10% per annum sum will double itself in 10 years .

12.5% per annumWhere P is principal amount, R is rate of interest and T will be time period. Hence, the rate of interest to double a money in 8 years will be 12.5% per annum.

= P and T = 16 yrs. Rate = (100 x P)/(P*16)% = 6 ¼ % p.a.

12.5% per annumHence, the rate of interest to double a money in 8 years will be 12.5% per annum.

Here, A is the total amount. So, rate of interest is 200%.

In your case, a rate of ~4.8% would double a sum in ~15 years. R=100*I/P*N=100*P/P*15=100/15=20/3=6.666… =6.67%.

So rate of interest should be 3 (1/3) to get some of money double itself..

=PRT100. Where P is principal amount, R is rate of interest and T will be time period. Hence, the rate of interest to double a money in 8 years will be 12.5% per annum.

So rate of interest should be 3 (1/3) to get some of money double itself.

Let principal = P.

Then, S.I.

= P and T = 16 yrs.

Rate = (100 x P)/(P*16)% = 6 ¼ % p.a..

Answer. R =? At 5% simple interest, a sum of money doubles itself in 20 years.

12.5%At what rate percent per annum will a sum of money double in 8 years. Rate = [(100 x P)/ (P x 8)]% = 12.5% per annum.

Here, we have R = 10% and have to calculate t for the sum of the money (that is P) to double.

Hence, it will take 10 years for the sum of money to double itself with the rate of 10% per annum simple interest..

Alternatively you can calculate what interest rate you need to double your investment within a certain time period.

For example if you wanted to double an investment in 5 years, divide 72 by 5 to learn that you'll need to earn 14.4% interest annually on your investment for 5 years: 14.4 × 5 = 72..

To use the Rule of 72 in order to determine the approximate length of time it will take for your money to double, simply divide 72 by the annual interest rate. For example, if the interest rate earned is 6%, it will take 12 years (72 divided by 6) for your money to double.

For example if you wanted to double an investment in 5 years, divide 72 by 5 to learn that you'll need to earn 14.4% interest annually on your investment for 5 years: 14.4 × 5 = 72.

The Rule of 72 is a simplified version of the more involved compound interest calculation..

This is the number of years it will take for your money to double. For example, if your money is earning an 8 percent interest rate, you'll double your money in 9 years (72 divided by 8 equals 9). Or, if your money is earning a 5 percent interest rate, you'll double it in 14.4 years (72 divided by 5 equals 14.4).

An investment that grows at 8% each year takes 9 years to double, while one that grows at 7% a year, doubles in 10.3 years. Just 1% more means… One-and-a-half year more of your money working for you, rather than you working for money!

10.2 yearsIf you invest at a 7% return, you will double your money every 10.2 years. (72/7 = 10.2)

The Rule of 72 states that the amount of time required to double your money equals 72 divided by your rate of return. For example: If you invest money at a 10 percent return, you will double your money every 7.2 years. If you invest at a 7 percent return, you will double your money every 10.2 years.
