## Understanding Finance Formulas – Your Step-by-Step Guide

1. Compound Interest Formula:

Compound interest lies at the heart of financial growth. It’s the concept of earning interest not only on the initial investment but also on the accumulated interest. The formula for compound interest is:

�=�×(1+��)��A=P×(1+nr​)nt

Where:

• A = Final amount
• P = Principal amount
• r = Annual interest rate (decimal)
• n = Number of times interest is compounded per year
• t = Time in years

To grasp the potential impact of compound interest, consider the article on The Magic of Compound Interest, which showcases real-life examples of how this formula can amplify your wealth over time.

## 2. Capital Asset Pricing Model (CAPM):

When assessing the risk and return of an investment, the CAPM formula proves invaluable. It helps you determine an asset’s expected return based on its risk and the risk-free rate. The formula is:

�(��)=��+��×(�(��)−��)E(Ri​)=Rf​+βi​×(E(Rm​)−Rf​)

Where:

• �(��)E(Ri​) = Expected return of the asset
• ��Rf​ = Risk-free rate
• ��βi​ = Beta of the asset
• �(��)E(Rm​) = Expected market return

4. Net Present Value (NPV) Formula: When evaluating the profitability of an investment, NPV considers the time value of money. It helps you decide whether an investment is financially viable by analyzing its projected cash flows. The formula is:

���=∑���(1+�)�−�0NPV=∑(1+r)tCFt​​−C0​

Where:

• ���CFt​ = Cash flow at time �t
• r = Discount rate
• t = Time period
• �0C0​ = Initial
