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.
Any investment can double in 5 years if it grows at a CAGR of 14.87% or more,” informs Certified Financial Planner, Lt. Col. (Retd.) Rochak Bakshi, Founder and CEO of True North Financial Services.
You plan to invest $100 per month for five years and expect a 6% return. In this case, you would contribute $6,000 over your investment timeline. At the end of the term, your portfolio would be worth $6,949. With that, your portfolio would earn around $950 in returns during your five years of contributions.
Here's the formula:
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.
If your employer offers a 401(k) with matching contributions, it's entirely possible to double your $1,000 investment. How much money your company matches will vary, but many offer to match half or even all of your contributions. If they offer 100% matching, you can double your money in no time.
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.
In fact, at the end of the five years, if you invest $1,000 per month you would have $83,156.62 in your investment account, according to the SIP calculator (assuming a yearly rate of return of 11.97% and quarterly compounding).
The table below shows the present value (PV) of $10,000 in 20 years for interest rates from 2% to 30%. As you will see, the future value of $10,000 over 20 years can range from $14,859.47 to $1,900,496.38.
Making $4,000 a month based on your investments alone is not a small feat. For example, if you have an investment or combination of investments with a 9.5% yield, you would have to invest $500,000 or more potentially. This is a high amount, but could almost guarantee you a $4,000 monthly dividend income.
Buy $4000 worth of goods at wholesale, resell them with a 150% markup. Pay your taxes. Done. Invest some of the money in tools and supplies and provide a service.
If you start with 1 dollar and double it every day for 30 days, you would have approximately $1,073,741,824. This shows the concept of exponential growth. Like the penny example, this is not typically possible in real-world investing scenarios.
To answer the question of how to double my money quickly, simply invest in a portfolio of investment options like ULIPs, mutual funds, stocks, real estate, corporate bonds, Gold ETFs, National Savings Certificate, and tax-free bonds, to name a few.
Here are the best low-risk investments in 2025:
High-yield savings accounts. Money market funds. Short-term certificates of deposit. Cash management accounts.
$3,000 X 12 months = $36,000 per year. $36,000 / 6% dividend yield = $600,000. On the other hand, if you're more risk-averse and prefer a portfolio yielding 2%, you'd need to invest $1.8 million to reach the $3,000 per month target: $3,000 X 12 months = $36,000 per year.
Yes, it's possible to retire on $1 million today. In fact, with careful planning and a solid investment strategy, you could possibly live off the returns from a $1 million nest egg.
You can retire comfortably on $3,000 a month in retirement income by choosing to retire in a place with a cost of living that matches your financial resources. Housing cost is the key factor since it's both the largest component of retiree budgets and the household cost that varies most according to geography.
If you put aside $5 per day, that's approximately $150 per month. And over the course of 30 years, you will have saved around $55,000 total. While that's a good chunk of change, it isn't $1 million or anywhere near it. The key is to invest those savings in a growth-focused ETF like the Invesco QQQ Trust.
If you have 10 or 20 years, you can turn that $500 per month into hundreds of thousands of dollars. For example, if you were to invest $500 into an S&P 500 index fund for 10 years, you could have more than $101,000 by the end of the 10th year.
According to the $1,000 per month rule, retirees can receive $1,000 per month if they withdraw 5% annually for every $240,000 they have set aside. For example, if you aim to take out $2,000 per month, you'll need to set aside $480,000.
Can you have more than one 401(k) account? Yes, you can, but having multiple 401(k) plans floating around isn't a good idea and should be avoided.
If your plan sponsor allows it, you can keep your retirement savings in their plan after you leave. While your earnings will still grow tax-deferred, you won't be able to contribute additional money to the account, though you can continue to manage your investments.
