How long does it take to double your money? ›

Years to double your money = 72 ÷ assumed rate of return. Consider: You've got $10,000 to invest and you hope to earn 8% over time. Just divide 72 by 8—which equals 9. Now you know it'll take approximately 9 years to grow your $10,000 to $20,000.

The rule of 72 is a shortcut investors can use to determine how long it will take their investment to double based on a fixed annual rate of return. All you do is divide 72 by the fixed rate of return to get the number of years it will take for your initial 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).

The rule of 72 is only an approximation that is accurate for a range of interest rate (from 6% to 10%). Outside that range the error will vary from 2.4% to 14.0%. It turns out that for every three percentage points away from 8% the value 72 could be adjusted by 1.

There are two approaches you could take. The first is increasing the amount you invest monthly. Bumping up your monthly contributions to $200 would put you over the $1 million mark. The other option would be to try to exceed a 7% annual return with your investments.

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.

If you earned around $50,000 per year before retirement, the odds are good that a $300,000 retirement account and Social Security benefits will allow you to continue enjoying your same lifestyle. By age 55 the median American household has about $120,000 saved for retirement, and about $212,500 in net worth.

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.

The rule of 8-4-3 when it comes to compounding indicates a style of investment that accelerates growth with time. Initially, a corpus doubles within 8 years through an average annual return of 12% subsequently another doubling happens for the same period after another 4 years following its initial setting up.

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.

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.

Imagine you wish to amass $3000 monthly from your investments, amounting to $36,000 annually. If you park your funds in a savings account offering a 2% annual interest rate, you'd need to inject roughly $1.8 million into the account. This substantial amount is due to savings accounts' relatively low return rate.
