Start by entering your initial deposit or investment, or your current balance if you already have a deposit.

This variation of the formula works for calculating time (t), by using natural logarithms.
At year five the gap in return is more than $2,500 while at year ten it is over $15,000 on that same $10,000 initial investment. For a deeper exploration of the topic, consider reading our article on how compounding works with investments. 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.

Interest can be compounded on any given frequency schedule, from continuous to daily, monthly, quarterly to annually. When calculating compound interest, the number of compounding periods makes a significant difference https://www.online-accounting.net/ for future earnings. Compound interest is a type of interest in which the interest amount is periodically added to the principal amount and new interest is subsequently accrued over interest from past periods.
- More frequent compounding results in higher future values, as interest is added to the principal more often.
- When interest compounding takes place, the effective annual rate becomes higher than the nominal annual interest rate.
- In their application, 20% of the principal amount was accumulated until the interest equaled the principal, and they would then add it to the principal.
- In this example you earned $1,000 out of the initial investment of $2,000 within the six years, meaning that your annual rate was equal to 6.9913%.
Now, let’s try a different type of question that can be answered using the compound interest formula. In this example, we will consider a situation in which we know the initial balance, final balance, number of years, and compounding frequency, but we are asked to calculate the interest rate. This type of calculation may be applied in a situation where you want to determine the rate earned when buying and selling an asset (e.g., property) that you are using as an investment.

To make it more pronounced, let us examine a hypothetical investment with a 15% annual rate of return over ten years.
In this example you earned $1,000 out of the initial investment of $2,000 within the six years, meaning that your annual rate was equal to 6.9913%. You can use the compound interest equation to find the value of an investment after a specified period or estimate the rate you have earned when buying and selling some investments. It also allows you to answer some other questions, such as how long it will take to double your investment. The concept of the time value of money states that a dollar today is worth more than a dollar in the future due to its potential earning capacity.

It can be used for any investment, as long as there is a fixed rate that involves compound interest. Simply divide the number 72 by the annual rate of return and the result of this is how many years it’ll take.

Example 3 – Calculating the interest rate of an investment using the compound interest formula
The final value after 5 years is $11,041 whereas with simple interest it would have been just $11,000.

The compound interest formula is an equation that lets you estimate how much you will earn with your savings account. It’s quite complex because it takes into consideration not only the annual interest rate and the number of years but also the number of times the interest is compounded per year. These example calculations assume a fixed percentage yearly interest rate. If you are investing your money, rather than saving it in fixed rate accounts,the reality is that returns on investments will vary year on year due to fluctuations caused by economic factors. Investment accounts can be classified as tax-deferred (e.g., 401(k), IRA) or taxable (e.g., regular brokerage accounts).
Using the definition above, the compound interest rate is the annual rate where the compounding frequency is taken into account. In other words, compounding interest means reinvesting the interest rather than paying it out, so that in the following period you earn interest on the principal sum plus the previously accumulated interest. Therefore, the more often the interest is added to (capitalized on) the principal amount, the faster your balance grows.
