This tool enables you to check how much time you need to double your investment even quicker than the compound interest rate calculator. As you can see this time, the formula is not very simple and requires a lot of calculations.

The Best Places to Save Money and Earn Interest
Let’s go back to the savings account example above and use the daily compound interest calculator to see the impact of regular contributions. We started with $10,000 and ended up with $4,918 in interest after 10 years in an account with a 4% annual yield. But by depositing an additional $100 each month into your savings account, you’d end up with $29,648 after 10 years, when compounded daily.

The Rule of 72 is a shortcut to determine how long it will take for a specific amount of money to double given a fixed return rate that compounds annually. One can use it for any investment as long as it involves a fixed rate with compound interest in a reasonable range. Simply divide the number 72 by the annual rate of return to determine how many years it will take to double. If your initial investment is $5,000 with a 0.5% daily interest rate, your interest after the first day will be $25. If you choose an 80% daily reinvestment rate, $20 will be added to your investment balance,
giving you a total of $5020 at the end of day one.
