The Black-Scholes formula also called Black-Scholes-Merton was the first widely used model for option pricing.
It's used to calculate the theoretical value of European-style options using current stock prices, expected dividends, the option's strike price, expected interest rates, time to expiration and expected volatility. The formula, developed by three economists — Fischer Black, Myron Scholes and Robert Merton — is perhaps the world's most well-known options pricing model, and was introduced in their paper, "The Pricing of Options and Corporate Liabilities" published in the Journal of Political Economy.
Black passed away two years before Scholes and Merton were awarded the Nobel Prize in Economics for their work in finding a new method to determine the value of derivatives the Nobel Prize is not given posthumously; however, the Nobel committee acknowledged Black's role in the Black-Scholes model.
While the original Black-Scholes model didn't consider the effects of dividends paid during the life of the option, the model is frequently adapted to account for dividends by determining the ex-dividend date value of the underlying stock.

The value of the option is calculated by taking the difference between the two parts, as shown in the equation. The mathematics involved in the formula is complicated and can be intimidating.
