# How Long Will It Take To Double My Money?

Regardless of how much money you start with, the time it takes to double depends on the interest rate; add your numbers to the calculator below to see your results…

This calculator uses the rule of 72.

i.e. an investment that grows at 7% per year will take 10.3 years to double in size (72 / 7 = 10.3)

The same rule applies to debt (unfortunately!), so check out my range of financial spreadsheets if you want to get a step ahead of those ever increasing credit card interest payments…!

## What's The Quickest Way To Double Your Money?

The quickest way to double your money largely depends on your risk tolerance and investment strategy. However, there are a few options that have the potential to double your money in a relatively short period of time.

One option is to invest in stocks. In the US, the average annual return of the S&P 500 index is around 10%. If you invest in a stock that doubles in value, you will have doubled your money.

For example, if you invest £10,000 in a stock that doubles in value, your investment will be worth £20,000. However, investing in stocks can be risky, and there is always the potential for losses.

Another option is to invest in real estate. In the UK, the average annual return on investment in residential property is around 8%. If you invest in a property that doubles in value, you will have doubled your money.

For example, if you invest £100,000 in a property that doubles in value, your investment will be worth £200,000. However, investing in real estate requires a significant amount of capital upfront and can be risky if the property market experiences a downturn.

A third option is to invest in a high-yield savings account or a certificate of deposit (CD). In the US, some high-yield savings accounts offer interest rates of up to 2%.

If you invest £10,000 in a high-yield savings account with a 2% interest rate, it will take approximately 35 years to double your money. However, investing in a CD with a higher interest rate can potentially double your money in a shorter period of time.

One example of a CD with a high interest rate is the Marcus by Goldman Sachs 5-year CD, which currently offers a 0.60% interest rate.

If you invest £10,000 in this CD, it will take approximately 120 years to double your money. However, if you invest £10,000 in a CD with a 6% interest rate, it will take approximately 12 years to double your money.

In conclusion, there are several ways to potentially double your money, but each option comes with its own risks and rewards. Investing in stocks or real estate can offer high returns but also carries a higher risk of loss. Investing in a high-yield savings account or CD offers lower risk but also lower returns. It’s important to do your research and consult with a financial advisor before making any investment decisions.

## What Interest Rate Will Double My Money in 7 Years?

The question of what interest rate is required to double your money in 7 years is a common one in both the UK and US.

The answer to this question depends on a number of factors, including the inflation rate, the type of investment, and the level of risk you are willing to take on. In this article, we will explore some of the key considerations when trying to double your money in 7 years and provide some examples of how this can be achieved.

Firstly, it is important to note that the inflation rate can have a significant impact on the interest rate required to double your money in 7 years.

Inflation is the rate at which prices for goods and services increase over time, and it can erode the purchasing power of your money. As a result, you need to earn a rate of return that is higher than the inflation rate in order to maintain the value of your money. In the UK, the current inflation rate is around 2%, while in the US it is around 1.5%.

This means that in order to double your money in 7 years, you would need to earn a rate of return of at least 10% in the UK and 9.5% in the US.

However, it is important to note that different types of investments offer different rates of return and come with different levels of risk.

For example, a savings account in the UK may offer an interest rate of around 1%, while a government bond may offer a rate of around 2%.

On the other hand, investing in stocks or shares can offer much higher rates of return, but also comes with a higher level of risk. In order to double your money in 7 years, you may need to take on more risk than you would be comfortable with in order to achieve the required rate of return.

## How Often Does My Money Double at 12%?

When it comes to investing, one of the most important factors to consider is how long it will take for your money to double. This is known as the “rule of 72,” which is a quick and easy way to estimate the number of years it will take for your investment to double based on a given interest rate. To use the rule of 72, simply divide 72 by the interest rate (as a percentage) to get the number of years it will take for your investment to double.

For example, if you have £1,000 invested at an interest rate of 12% per year, it will take approximately 6 years for your money to double using the rule of 72. This is calculated by dividing 72 by 12, which equals 6.

In the US, the same calculation would apply. If you have $1,000 invested at an interest rate of 12% per year, it will also take approximately 6 years for your money to double using the rule of 72.

It’s important to note that the rule of 72 is just an estimation, and actual results may vary based on a number of factors such as taxes, fees, and market fluctuations. However, it can be a useful tool for quickly estimating the potential growth of your investments.

To illustrate this point further, let’s look at some real-world examples. Suppose you have £10,000 invested in a savings account with an interest rate of 12% per year. Using the rule of 72, we can estimate that it will take approximately 6 years for your money to double to £20,000.

Now, let’s suppose you have the same amount invested in the stock market, which historically has had an average annual return of around 10%. Using the rule of 72, we can estimate that it will take approximately 7.2 years for your money to double to £20,000.

It’s important to remember that investing in the stock market comes with risks, and past performance is not a guarantee of future results. However, over the long term, stocks have historically provided higher returns than savings accounts or other low-risk investments.

In the US, let’s suppose you have $10,000 invested in a 401(k) retirement account with an average annual return of 12%. Using the rule of 72, we can estimate that it will take approximately 6 years for your money to double to $20,000.

Now, let‘s suppose you have the same amount invested in a low-risk bond with an interest rate of 3%. Using the rule of 72, we can estimate that it will take approximately 24 years for your money to double to $20,000.

As you can see, the length of time it takes for your money to double can vary greatly depending on the type of investment you choose. Higher-risk investments such as stocks have the potential for higher returns but also come with greater risk, while lower-risk investments such as savings accounts and bonds offer lower returns but also come with less risk.

It’s important to consider your own risk tolerance and investment goals when choosing where to invest your money. If you’re willing to take on more risk in exchange for potentially higher returns, then stocks or other higher-risk investments may be a good choice for you. However, if you’re more interested in preserving your capital and don’t want to take on as much risk, then a savings account or low-risk bond may be a better option.

In conclusion, the rule of 72 is a useful tool for estimating how long it will take for your money to double based on a given interest rate. In the UK and US, an interest rate of 12% would take approximately 6 years for your money to double using this rule. However, actual results may vary based on a number of factors, and it’s important to consider your own risk tolerance and investment goals when choosing where to invest your money.
