Interactive Concept: Internal Rate of Return (IRR)

The IRR is the discount rate at which your investment breaks even in present value terms: where NPV equals zero. Set your cash flows, then compare the IRR to your WACC (discount rate) to make an accept or reject decision. Click or drag anywhere on the graph to explore different WACC scenarios.

CASH FLOW TIMELINE & PV DIAGRAM
Each arrow shows a future cash flow discounted back at the IRR rate. At this rate, the present values in the yellow column sum exactly to your initial investment, confirming NPV = $0.
Initial Investment (CF₀)
The upfront outflow at time zero. Enter as a negative number.

NPV vs. Discount Rate (WACC)

The purple line marks the IRR, where the NPV curve crosses zero. Click or drag the graph to move your WACC marker, or use the slider below.

Discount Rate (WACC)

The same discount rate from the NPV concept: your cost of capital. When the IRR exceeds your WACC, the investment returns more than it costs (accept). When it falls below, reject.

Discounting Breakdown at IRR

Each row shows how the IRR rate discounts a future cash flow to its present value. The total present value in the last row should match the initial investment, confirming NPV = $0 at the IRR.
