What is Present Worth?

Present Worth (PW), also known as Present Value, is a fundamental concept in finance and economics, vital for both individuals and businesses. This critical financial metric helps in evaluating the current value of a future sum of money or series of cash flows, considering a specific time frame and interest rate.

Why Present Worth Matters

In a world where the value of money changes over time due to factors like inflation and interest rates, understanding Present Worth is essential. It equips investors, financial planners, and business owners with the insight to make informed decisions about investments, loans, and other financial matters.

The Principle Behind Present Worth

The core principle of Present Worth revolves around the time value of money, which states that a dollar today is worth more than a dollar tomorrow. This principle is crucial in areas such as:

  • Investment Decisions: Determining whether an investment’s future returns justify the initial outlay.
  • Loan Analysis: Understanding the true cost of borrowing and comparing different loan options.
  • Retirement Planning: Estimating the amount needed to invest today to achieve a desired financial goal in the future.
Present Worth Formula
\( PW = \frac{F}{(1 + i)^n} \)
  • PW – Present Worth or Present Value
  • F – Future sum of money or future value
  • i – Interest rate or discount rate per period
  • n – Number of periods (years, months, etc.)

Present Worth Example Problem

Present Worth Example Problem

Problem Statement

Calculate the present worth of a future sum of $5000 to be received in 3 years, assuming an annual discount rate of 5%.

  • Future Value (F) – $5000
  • Interest Rate (i) – 5% per year
  • Number of Periods (n) – 3 years
Solution Steps

Step 1: Identify the values

F = $5000, i = 5%, n = 3 years

Step 2: Convert interest rate to decimal

i = 5% = 0.05

Step 3: Substitute values into the Present Worth formula

\[ PW = \frac{F}{(1 + i)^n} \]

\[ PW = \frac{5000}{(1 + 0.05)^3} \]

Step 4: Calculate the Present Worth

\[ PW = \frac{5000}{1.157625} \]

\[ PW \approx \$4319.66 \]


What is Present Worth?

Present Worth, also known as Present Value, is a financial concept used to determine the current value of a future sum of money or stream of cash flows given a specified rate of return. It reflects the idea that money available at the present time is worth more than the same amount in the future due to its potential earning capacity.

Why is Present Worth important in finance?

Present Worth is crucial in finance for evaluating investment opportunities, comparing financial products, and making decisions about loans. It helps in understanding the value of future money in today’s terms, making it easier to plan and invest wisely.
