Interest calculation and investment strategies

Interest rates and investment strategies are two key factors that are critical to achieving financial success. Accurate interest calculations and effective investment strategies help investors increase their income and achieve their long-term financial goals. In addition, using interest rates effectively and correctly is a very effective method for people to earn a stable monthly income.

How are interest rates calculated?

Interest rates It is the additional fee that the lender demands in return for the money given to the borrower or institution. This rate is calculated on the principal amount of the debt for a certain period of time. There are several basic formulas for calculating interest rates.

1. Simple interest

Simple interest is interest calculated only once on the principal. In simple interest calculation, the interest amount is determined only on the principal and remains constant throughout the period. Its formula is as follows:

• Interest = Principal x Interest Rate x Time

For example, if you invest 1000 TL with a 5% interest rate for 1 year, the interest you will earn is:

• Interest = 1000 x 0.5 x 1 = 50 TL

In this case, the total amount (principal + interest) will be 1050 TL.

2. Compound interest

Compound interest is calculated on the sum of the principal and interest of previous periods. This method means that interest income is added to the principal at the end of each period and reinvested. The formula used to calculate compound interest is as follows:

Here,

• A: Future value (principal + interest)
• P: Initial principal
• r: Annual interest rate
• n: per year interest calculation frequency
• t: Number of years

can be expressed as .

For example, if you invest $1,000 for 2 years at a 5% annual interest rate and the interest is compounded annually, the future value is:

• A = 1000 (1 + 0.05/1)^1×2 = 1102.50 TL.

3. Nominal and real interest rates

Interest rates are divided into nominal and real. Nominal interest rate is the interest rate calculated without taking into account the inflation rate. The real interest rate is the remaining real interest rate after subtracting the inflation rate. The real interest rate shows the investor’s real return. The real interest rate helps investors understand their true earnings and shows how inflation affects investment returns.

Real Interest Rate = Nominal Interest Rate – Inflation Rate

For example, if the annual nominal interest rate is 6% and the annual inflation rate is 2%, the real interest rate is:

• Real Interest Rate = 6 – 2 = 4, so the real interest rate will be 4%.

Investors should adjust these balances according to their risk appetite and financial goals.

A diversified portfolio is more resilient to market fluctuations and provides stable returns over the long term.
