How long does it take to double your money? ›

Do you know the Rule of 72? 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.

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 (1.10^7.3 = 2).

One of those tools is known as the Rule 72. For example, let's say you have saved $50,000 and your 401(k) holdings historically has a rate of return of 8%. 72 divided by 8 equals 9 years until your investment is estimated to double to $100,000.

As a rate of return, long-term mutual funds can offer rates between 12% and 15% per year. With these mutual funds, it may take between 5 and 6 years to double your money.

Assuming an annual return rate of 7%, investing $50,000 for 20 years can lead to a substantial increase in wealth. If you invest the money in a diversified portfolio of stocks, bonds, and other securities, you could potentially earn a return of $159,411.11 after 20 years.

Let's walk through the scenario. With $300,000 planned for your use as a retiree, a retirement age of 50, and an anticipated life expectancy of 85 years, you need that money to last you 35 years. This should mean that your yearly income is around $8,571, and your monthly payment is around $714.

“By the time you hit 33 years old, you should have $100,000 saved somewhere,” he said, urging viewers that they can accomplish this goal. “Save 20 percent of your paycheck and let the market grow at 5% to 7% per year,” O'Leary said in the video.

You still have roughly 20 years before the conventional retirement age, so make the most of your savings opportunities. Fidelity says by age 40, aim to have a multiple of three times your salary saved up. That means if you're earning $75,000, your retirement account balance should be around $225,000 when you turn 40.

As a very basic example, if you had $5,000 in your 401(k) today, and it grew at an average rate of 5% per year, it would be worth $10,441 in 20 years—more than double. If you withdraw those funds early, however, you're not only facing a stiff tax penalty, you're losing all of that additional growth.

If you keep saving, you can get there even faster. If you invest just $500 per month into the fund on top of the initial $100,000, you'll get there in less than 20 years on average. Adding $1,000 per month will get you to $1 million within 17 years. There are a lot of great S&P 500 index funds.

How can you make $5,000 turn into $10,000? Turning $5,000 into $10,000 involves investing in avenues with the potential for high returns, such as stocks, ETFs or real estate. Another approach is to use the money as seed capital for a profitable small business or side hustle.

If your initial amount was X, it becomes 2*X = 2X after 7 years. Now, if you start with 2X, it would become 2*2X= 4X in 7 more years. Overall it will take 7+7= 14 years to become fourfold!

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.
