## Net Present Value (NPV) Terms

**Net Present Value (NPV)** is a financial metric that calculates the present value of future cash flows generated by a project or investment, minus the initial investment. It's used to assess the profitability of an investment.

### NPV Formula

`NPV = ∑ [Cash Flow / (1 + r)^t] - Initial Investment`

## NPV Formula

Symbol Description NPV Net Present Value CF Cash Flow r Discount Rate t Time period

Formula Meaning NPV = Î£ [CF / (1 + r)^t] - Initial Investment Calculates the present value of future cash flows minus the initial investment

Note:

- Î£ represents the summation of all cash flows.
- The formula calculates the present value of each cash flow by dividing it by (1 + r)^t, where r is the discount rate and t is the number of periods.
- The initial investment is subtracted from the sum of the present values of cash flows.

## NPV Calculation Example

Note: This example demonstrates the basic structure of an NPV calculation table. Actual calculations will vary based on specific project data.

Year Cash Flow Discount Rate Discount Factor Present Value 0 -Initial Investment 1 Cash Flow Year 1 Discount Rate 1/(1+Discount Rate)^1 Cash Flow Year 1 * Discount Factor 2 Cash Flow Year 2 Discount Rate 1/(1+Discount Rate)^2 Cash Flow Year 2 * Discount Factor 3 Cash Flow Year 3 Discount Rate 1/(1+Discount Rate)^3 Cash Flow Year 3 * Discount Factor ... ... ... ... ... n Cash Flow Year n Discount Rate 1/(1+Discount Rate)^n Cash Flow Year n * Discount Factor NPV = Sum of Present Values

- Cash Flow: Net cash inflow or outflow for each year.
- Discount Rate: The required rate of return.
- Discount Factor: Used to calculate the present value of future cash flows.
- Present Value: The value today of a future cash flow.
- NPV: The sum of all present values minus the initial investment.

Remember:

- Negative cash flows typically occur at the beginning (initial investment) and might occur in other periods (e.g., reinvestments).
- Positive cash flows represent cash inflows.
- The discount factor decreases as the time period increases, reflecting the time value of money.

Year | Cash Flow | Discount Rate | Discount Factor | Present Value |
---|---|---|---|---|

0 | -Initial Investment | |||

1 | Cash Flow Year 1 | Discount Rate | 1/(1+Discount Rate)^1 | Cash Flow Year 1 * Discount Factor |

2 | Cash Flow Year 2 | Discount Rate | 1/(1+Discount Rate)^2 | Cash Flow Year 2 * Discount Factor |

3 | Cash Flow Year 3 | Discount Rate | 1/(1+Discount Rate)^3 | Cash Flow Year 3 * Discount Factor |

... | ... | ... | ... | ... |

n | Cash Flow Year n | Discount Rate | 1/(1+Discount Rate)^n | Cash Flow Year n * Discount Factor |

NPV = Sum of Present Values |

- Cash Flow: Net cash inflow or outflow for each year.
- Discount Rate: The required rate of return.
- Discount Factor: Used to calculate the present value of future cash flows.
- Present Value: The value today of a future cash flow.
- NPV: The sum of all present values minus the initial investment.

Remember:

- Negative cash flows typically occur at the beginning (initial investment) and might occur in other periods (e.g., reinvestments).
- Positive cash flows represent cash inflows.
- The discount factor decreases as the time period increases, reflecting the time value of money.

## NPV Calculation Example

Assumptions:

- Initial investment: -$100,000 (negative as it's a cash outflow)
- Cash flows for years 1-5: $30,000, $35,000, $40,000, $45,000, $50,000
- Discount rate: 10%

Year Cash Flow Discount Rate Discount Factor Present Value 0 -$100,000 10% 1 -$100,000 1 $30,000 10% 0.9091 $27,273 2 $35,000 10% 0.8264 $28,924 3 $40,000 10% 0.7513 $30,052 4 $45,000 10% 0.6830 $30,735 5 $50,000 10% 0.6209 $31,045 NPV = $48,029

Note:

- The discount factor is calculated as 1 / (1 + discount rate)^year.
- The present value is calculated as cash flow * discount factor.
- The NPV is the sum of all present values.

In this example, the NPV is positive, indicating that the project is expected to generate more value than its initial cost and is therefore considered profitable.

Assumptions:

- Initial investment: -$100,000 (negative as it's a cash outflow)
- Cash flows for years 1-5: $30,000, $35,000, $40,000, $45,000, $50,000
- Discount rate: 10%

Year | Cash Flow | Discount Rate | Discount Factor | Present Value |
---|---|---|---|---|

0 | -$100,000 | 10% | 1 | -$100,000 |

1 | $30,000 | 10% | 0.9091 | $27,273 |

2 | $35,000 | 10% | 0.8264 | $28,924 |

3 | $40,000 | 10% | 0.7513 | $30,052 |

4 | $45,000 | 10% | 0.6830 | $30,735 |

5 | $50,000 | 10% | 0.6209 | $31,045 |

NPV = $48,029 |

Note:

- The discount factor is calculated as 1 / (1 + discount rate)^year.
- The present value is calculated as cash flow * discount factor.
- The NPV is the sum of all present values.

In this example, the NPV is positive, indicating that the project is expected to generate more value than its initial cost and is therefore considered profitable.
