**Doubling Time (Continuous Compounding)**

Successfully Doubling Time Continuous Compounding

** Using the doubling time formula with continuous compounding is one of the best ways to calculate the length of time needed in order to double funds in an investment or account.** This formula is used to find the time it takes in order to double funds. A prime example of this would be monthly rates. If a monthly rate is utilized, the answer will reflect in the number of months needed for doubling funds. If an annual rate is utilized, the answer will reflect in the number of years needed for doubling funds.

This is a formula where we can find the doubling time of an investment earning :

**Doubling Time = ln(2)/r** where r is rate

You can change the rate in percent. **In this example if annually I have 6% growth than in 11.5 years I will double my account.If I have 7% annulary growth than in all most 7 years I will double my account.**

There are many practical uses for this formula. One of the main uses is to discover how long a certain increase in funds will take. The type of increase is a full double. This means that the individual is looking to double the number of funds in their account. The formula will be based upon the amount of time used in the rate. If an individual wants to find how long it will take to double funds with a 6% annual continuous compound, they would take a few steps to find the answer. The first step for solving this equation would be to calculate the number of years needed to double the investment. The annual rate must be used in order to solve this step in the equation. The answer to this specific equation is 11.5 years. This is one example of how the doubling time formula can be successfully solved with the feature of continuous compounding.

It is important to note how the doubling time formula was derived. The first step to understanding this formula is to look at the basic continuous compounding formula. FV represents future value and PV represents the present value. In order to successfully double funds, the future value must equal twice the value of the PV. Once this is accomplished, the funds have been doubled. In order to understand this equation, one can substitute 2 for FV and 1 for the variable of PV. The formula can also be adjusted as well. The formula can also be rewritten in order to solve for “T.”

It is also important to note that the denominator of the formula also becomes “R.” The doubling time formula has been used for a wide variety of scenarios. It is a common task to solve this equation when looking to double funds. As stated previously, a monthly rate or annual rate may be used in order to fully solve this formula. There are two main ways to solve this equation. One of the methods involves calculating the number of months, while the other method involved calculating the number of years. Either method can be used depending upon the specifics. The formula is used with the rate of return. The rate of return plays a role in solving this equation. Investments and accounts are both involved with this specific formula and can help solve the equation for doubling time with the feature of continuous compounding.
