Basic Math You Should Know Before Investing in Stocks Market

Since stock market investing includes mathematical formulas, many consider it highly complicated. They struggle with making trading and investing strategies and conducting fundamental and technical analyses. However, stock market math does not require advanced mathematics. It can easily be comprehended with the concepts of basic mathematics. This article will examine basic stock market mathematics essential to making sound decisions before investing in stocks. 

Return on Equity (ROE)

Return on Equity (ROE) is an important formula to calculate the efficiency and profitability of a company in the market. Mathematically, it is the ratio of net income to shareholders' equity. The greater the value of this ratio, the higher the efficiency and profitability. The shareholders' equity is expressed as the company's assets, subtracting its debt. A company's net income is its total earnings minus expenses and taxes.

Due to its higher expense deduction than other profitability measures like gross income or operating income, it is the most secure measure that a company can evaluate. Investors should understand and use the ROE formula to evaluate its implications. A consistent and high return on equity shows a company's capacity to make money from its equity.

Risk Management in Stock Market through Math Formula

Risk management is one of the most important steps to investing in the stock market. Investors evaluate and analyse stock market risk before deciding whether to invest. Assessment and management of risks are key parts of the basic math involved in the stock market. Their formulas include standard deviation (SD), value at risk (VaR), R-squared, Sharpe ratio, and conditional value at risk (CVaR). 

Before investing, investors should also calculate the risk-to-return ratio. This involves dividing the potential loss if the investment doesn’t meet expectations by the potential gain if it performs as anticipated. 

 Compute Future Value for Well-Informed Investing

The potential worth of their investments worries investors a lot. Potential worth implies projecting an investment's future value while accounting for compound interest. Investors can calculate their potential growth over time using the future value formula, allowing them to make well-informed judgments based on the projected future value of their portfolios. It's a potent instrument, especially for long-term investors hoping to capitalize on compounding. A simulation is used in the future value calculator to determine an investment's future value. It displays the future value of your money. A future value calculator is an analytical tool that can be used to determine the value of any investment at a specific future date.

The mathematical formula used is as follows:

A = PMT ((1+r/n)^nt – 1) / (r/n))

According to the formula, deposits are expected to be made after each month or year.

A = Investment's Future Value

PMT = Total Amount Paid Every Period

n = The quantity of compounds in one investment period

t = Total number of investment periods. 

Earnings Per Share (EPS)

Earnings per share (EPS) is a corporation's net profit over a specific period. The formula can compute it.

EPS = Average Outstanding Shares / (Net Income – Dividends on Preferred Stock).

Investors must pay attention to shares not included in the EPS calculation, either annually or quarterly. Earnings per share (EPS) is calculated as a company's profit divided by the current shares of its common stock. The value that came out as a solution to the above formula shows a company's profitability. A greater value indicates higher profitability. Companies frequently report EPS adjusted for unusual expenses and possible share dilution.

Price-to-earnings (P/E) ratio

According to the price-to-earnings ratio, a company is determined to be overvalued or undervalued. A low P/E ratio means a stock or company is undervalued compared to its peers within the same sector. The formula to calculate the P/E ratio is the market price per share/earnings per share for the preceding 12 months.


Understanding essential mathematical formulas and concepts is crucial in the stock market. Use these essential math concepts to improve your understanding of finance while you explore the world of stocks.
