IRR Equation with Salvage Value:

\[ -Initial + \sum_{t=1}^{n}\frac{CF_t}{(1 + r)^t} + \frac{Salvage}{(1 + r)^n} = 0 \]

1. What is IRR with Salvage Value?

The Internal Rate of Return (IRR) including salvage value is the discount rate that makes the net present value (NPV) of all cash flows (including the salvage value at the end) equal to zero. It's a key metric in capital budgeting to evaluate the profitability of potential investments.

2. How Does the Calculator Work?

The calculator uses the IRR equation with salvage value:

\[ -Initial + \sum_{t=1}^{n}\frac{CF_t}{(1 + r)^t} + \frac{Salvage}{(1 + r)^n} = 0 \]

Where:

\( Initial \) — Initial investment amount
\( CF_t \) — Cash flow at time period t
\( Salvage \) — Salvage value at end of project
\( n \) — Number of periods
\( r \) — IRR (the solution to the equation)

Explanation: The equation is solved iteratively (using Newton-Raphson method) to find the rate (r) where the sum of discounted cash flows equals the initial investment.

3. Importance of IRR Calculation

Details: IRR helps compare profitability of investments. A project is generally considered good if its IRR exceeds the required rate of return. Including salvage value provides a more complete picture by accounting for residual asset value.

4. Using the Calculator

Tips: Enter initial investment (positive value), comma-separated cash flows (positive for inflows, negative for outflows), and salvage value (typically positive). All values must be valid numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's a good IRR value?
A: Generally, IRR should exceed the company's cost of capital. The higher the IRR, the more desirable the project.

Q2: How does salvage value affect IRR?
A: Salvage value increases the final cash flow, typically resulting in a higher IRR compared to calculations without it.

Q3: What are limitations of IRR?
A: IRR assumes reinvestment at the calculated rate and can give misleading results with unconventional cash flow patterns.

Q4: How accurate is this calculator?
A: It provides a close approximation using numerical methods. For complex scenarios, professional financial software may be needed.

Q5: Can IRR be negative?
A: Yes, a negative IRR indicates the project loses money at any discount rate.
