Financial Literacy: Simple Vs Compound Interest in Crypto (And Other Essential Terms)

Financial Literacy: Simple Vs Compound Interest in Crypto (And Other Essential Terms)

As the cryptocurrency world continues to grow and evolve, it is becoming increasingly important for investors to have a solid understanding of financial literacy, and understanding the difference between simple and compound interests is one of them.

Key Terms And Mechanics to Know

Interest is the expense incurred when borrowing money, where the borrower compensates the lender for the use of their funds. Interest is typically represented as a percentage and can be categorized as either simple or compound.

Simple interest is calculated solely on the initial amount borrowed or deposited, while compound interest takes into account both the principal and the interest earned during each period. Due to its reliance on the principal amount alone, calculating simple interest is simpler compared to compound interest.

Simple Interest

Simple interest is tied to the initial investment amount and does not affect interest earned over time. This is a fixed rate that does not change when additional interest is added.

Simple interest is the simplest form of interest and is calculated based on the initial amount of investment. For example, if you invest $1,000 in a cryptocurrency with a simple interest rate of 5%, you'll earn $50 in interest after one year. This interest is calculated based on the initial investment amount and does not consider any additional interest earned over time.

Compound Interest

The compound interest rates are more dynamic. It takes into account both the original amount invested and the interest earned. Each time you add interest to your investment (rather than withdrawing it immediately after it is earned), the next calculation is based on a new higher amount. Because of this complex effect, your investments grow faster than those with simple interest accruals.

It is a more complex form of interest that considers both the initial amount invested and the interest earned over time. This means that as your investment grows, so does your amount of interest. For example, if you invest $1,000 in a cryptocurrency with a compound interest rate of 5%, you'll earn $50 in interest after one year. 

However, if you reinvest that interest back into the investment, your total investment will grow to $1,050, and you will earn interest in that new amount the following year. This compounding effect can result in significant growth over time.

Understanding Simple and Compound Interest Formulas

When it comes to borrowing or investing money, understanding the concepts of simple and compound interests is crucial. These formulas help determine the amount of interest payable or earned over a specific period. In this article, we discuss simple and compound interest formulas and how they work.

Simple Interest Formula

The simple interest formula is used to calculate the interest payable on a loan or investment that is not compounded over time. The formula used is as follows:

Simple Interest = Principal x Rate x Time

Where:

  • Principal is the initial amount borrowed or invested;
  • Rate is the interest rate charged or earned;
  • Time is the duration of the loan or investment in years.

For example, if we borrow $10,000 at a simple interest rate of 5% for three years, the total amount of interest payable can be calculated as follows:

Simple Interest = $10,000 x 0.05 x 3 = $1,500

This means that the borrower would have to pay $500 in interest annually or $1,500 over the three-year loan term.

Compound Interest Formula

The compound interest formula is used to calculate the interest payable or earned on a loan or investment that compounds over time: Compound interest is the interest earned on the initial principal as well as the accumulated interest from previous periods. 

A = P(1 + r/n)^nt

Where:

  • A is the final amount or future value;
  • P is the principal amount;
  • r is the interest rate;
  • n is the number of times interest is applied per time period;
  • t is the time elapsed.

For example, if you invest $10,000 at a compound interest rate of 5% for three years, the future value of your investment can be calculated as follows:

A = $10,000 x (1 + 0.05)^3 = $11,576.25

This means that the total interest earned would be $1,576.25 over the three-year investment period.

Other Terms to Know

Other important terms to understand when it comes to interest in crypto include the annual percentage rate (APR), annual percentage yield (APY), and frequency of interest payments (daily, weekly, monthly, etc.). If APY and APR are different when you think about investing, it is useful to consider both APY and APR.

APR helps you determine the percentage you will pay for interest and commissions over the year, but it does not consider compounding. The APY is very important because it considers compounding, but usually does not consider commissions. To obtain a true return on investment, we need to subtract these fees.

Therefore, even if APY and APR are somewhat different when you think about investing, it is useful to consider both APY and APR. APR helps to determine the percentage you pay for interest and commissions during the year, but it does not take into account compound interest.

APY is very important because it takes into account compound interest, but usually does not take into account commissions. To get a real return on investment, you need to deduct these fees. Thus, the combination of APR and APY gives you a more accurate idea of how valuable your investment is.

Conclusion

In the cryptocurrency market compound interest is often a factor in business transactions, investments, and financial products that span multiple periods or years. Simple interest rates are mainly used for simple calculations: they are usually for one period or less than a year, although they also apply to open-ended situations such as credit card balances.

Navigating the cryptocurrency market requires an understanding of terms rooted in traditional finance. Having studied the complexities of API and APR, you have gained the knowledge necessary to make informed decisions in the cryptocurrency space.

Now, whether you want to stack on platforms like Binance or immerse yourself in decentralized finance, understanding these financial concepts will allow you to optimize your returns and minimize your risks. Decisions are always made based on a clear understanding of these basic financial principles.
