Initial Investment: $10,000.00
Cash Flows: 4 periods
How to use
- Set the Initial Investment and enter expected Cash Flows for each period.
- IRR is the discount rate that makes NPV = 0 — treat as an estimated annualized return.
- 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.
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.
How to use the IRR calculator
Find the implied return rate from a stream of cash flows. Before calculating, enter accurate inputs: Enter initial outflow and periodic inflows or outflows.
After you get the output, interpret it like this: Compare IRR against your required return hurdle rate. Practical tip: Projects with irregular cash flows may need extra interpretation.This calculator is for planning and scenario analysis, so use it with your broader risk management, position sizing, and market context before taking a real trade or investment decision.
