Simple Interest versus Compound Interest

This is because a higher compounding frequency implies more substantial growth on your balance, which means you need a lower rate to reach the same amount of total interest. Hence, if a two-year savings account containing $1,000 pays a 6% interest rate compounded daily, it will grow to $1,127.49 at the end of two years. This formula takes into consideration the initial balance P, the annual interest rate r, the compounding frequency m, and the number of years t. Inspired by his own need to calculate long-term investment returns and simplify the process for others, Tibor created this tool. It’s designed to help users plan their financial future, whether for retirement, saving for a home, or understanding the potential growth of their investments.

Anyone who wants to estimate compound interest in their head may find the rule of 72 very useful. Not for exact calculations as given by financial calculators, but to get ideas for ballpark figures. It states that in order to find the number of years (n) required to double a certain amount of money with any interest rate, simply divide 72 by that same rate.

Let’s break down the interest compounding by year with a more realistic example scenario. We’ll say you have $10,000 in a savings account earning5% interest per year, with annual compounding. We’ll assume you intend to leave the investment untouched for 20 years. Looking back at our example, with simple interest (no compounding), your investment balanceat 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.

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. In reality, investment returns will vary year to year and even day to day.

Formula methodology

LIBOR is a commercial rate calculated from prevailing interest rates between highly credit-worthy institutions. 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.

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. Because lenders earn interest on interest, earnings compound over time like an exponentially growing snowball. Therefore, compound interest can financially reward lenders generously over time. The longer the interest compounds for any investment, the greater the growth.

The more frequently that interest is calculated and credited, the quicker your account grows. The interest earned from dailycompounding will therefore be higher than monthly, quarterly or yearly compounding because of the extra frequency of compounds. With compound interest, the interest you have earned over a period of time is calculatedand then credited back to your starting account balance. In the next compound period, interest is calculated on the total of the principal plus thepreviously-accumulated interest. Note, that if you leave the initial and final balances unchanged, a higher the compounding frequency will require a lower interest rate.

The more frequently interest is compounded within a time period, the higher the interest will be earned on an original principal. The following is a graph showing just that, a $1,000 investment at various compounding frequencies earning 20% interest. This Compound Interest Calculator can help determine the compound interest accumulation and final balances on both fixed principal amounts and additional periodic contributions. There are also optional factors available for consideration, such as the tax on interest income and inflation.

For a deeper exploration of the topic, consider reading our article on how compounding works with investments. Use this calculator to easily calculate the compound interest and the total future value of a deposit based on an initial principal. Daily compound interest is calculated using a version of the compound interest formula.To begin your calculation, take your daily interest rate and add 1 to it. Then, raise that figure to the power of the number of days you want to compound for.

The easiest way to take advantage of compound interest is to start saving! 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. 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.
