IRR Analysis

Internal Rate of Return
12.83%
Annualized return rate

Initial Investment: $10,000.00

Cash Flows: 4 periods

NPV at IRR
$0.00
Should be close to 0 (IRR definition)
Interpretation
Positive IRR indicates a potentially profitable investment. Compare this rate with your required rate of return to assess attractiveness.

How to use

  1. Set the Initial Investment and enter expected Cash Flows for each period.
  2. IRR is the discount rate that makes NPV = 0 — treat as an estimated annualized return.
  3. Compare IRR to your required rate of return to decide if the investment is attractive.

What is IRR?

The Internal Rate of Return (IRR) is the discount rate where the present value of cash inflows equals cash outflows (NPV = 0). It is useful for comparing project returns but can be misleading with non-conventional cash flows.

Use cases: project comparison, ranking investments, quick return estimates.

Example & Presets

Example: Initial investment $10,000 with cash flows $2,000, $3,000, $4,000 and $5,000.

Tips & Limitations

  • Non-conventional cash flows can produce multiple IRRs — interpret cautiously.
  • IRR ignores scale; compare with NPV and absolute returns.
  • Use as a guide, not a sole decision metric.
