In this case, the number of periods when compounding occurs is infinite, as compounding would happen in every possible moment. To see its mathematical background, read the section on Natural logarithm in our log calculator. For example, $100 with a fixed rate of return of 8% will take approximately nine (72 / 8) years to grow to $200. Bear in mind that “8” denotes 8%, and users should avoid converting it to decimal form. Also, remember that the Rule of 72 is not an accurate calculation.
While compound interest is applicable whenever the interest is up for payment it will be added back to the principal amount. In simple interest, you only earn interest on the principal investment amount. Note that if you wish to calculate future projections without compound interest, we have a

Compound Interest Formula & Steps to Calculate Compound Interest
Compound interest is a potent financial concept that enables investors to earn interest not only on their initial investment but also on interest earned over time. Daily interest calculation is a variation of compound interest known as compound daily interest. This article will examine daily compound interest and its calculation. Compounding is the ability of money to grow exponentially due to the repeated addition of earnings to the initial investment over time. This is the reason experts advise people to invest as early as they can.
They are included in many older financial textbooks as an appendix. It is also worth knowing that exactly the same calculations may be used to compute when the investment would triple (or multiply by any number, in fact). All you need to do is just use a different multiple of P in the second step of the above example. Note that the greater the compounding frequency is, the greater the final balance.
How do you calculate interest compounded continuously?
The rule of 72 helps you estimate the number of years it will take to double your money. The method is
simple – just divide the number 72 by your annual interest rate. The effective annual rate (also known as the annual percentage yield) is the rate of interest that you actually receive on your savings or investment after compounding has been factored in.
It did not matter whether one measured the intervals in years, months, or any other unit of measurement. Each additional period generated higher returns for the lender. Bernoulli also discerned that this sequence eventually approached a limit, e, which describes the relationship between the plateau and the interest rate when compounding. After 10 years of compounding, you would have earned a total of $4,918 in interest.

5% interest per year, with annual compounding.
The continuous compound interest formula
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. When it comes to choosing between simple and compound interest, compound interest will always win. But, there’s a way that you can make compound interest work harder for you. When you’re choosing an investment avenue that offers compound interest, you can also look at how often the interest is compounded. You can choose plans where the interest is accrued daily, monthly, six-monthly or annually.
To see how compound interest differs from simple interest, use our simple interest vs compound interest calculator. Just enter your beginning balance, the regular deposit amount at any specified interval, the interest rate, compounding interval, and the number of years you expect to allow your investment to grow. Looking back at our example, with simple interest (no compounding), your investment balance
at the end of the term would be $13,000, with $3,000 interest. With regular interest compounding, however, you would stand to gain an additional $493.54 on top.
