Annual Cash-Flow IRR Calculator

Calculate annual IRR for one initial investment followed by up to five annual receipts.

01 / UNDERSTAND THE CONCEPT

When the money returns changes the return.

IRR is the annual discount rate that sets the net present value of a cash-flow sequence to zero. Earlier distributions can increase IRR even if the total investment multiple is unchanged.

This calculator deliberately supports one initial outflow followed by nonnegative annual receipts. That conventional pattern has one finite root whenever at least one receipt is positive. Further capital calls, irregular dates and alternating signs require a different cash-flow model and can introduce multiple or missing roots.

02 / THE MATHEMATICS

The formula, made clear.

0 = −initial investment + Σ annual receiptₜ / (1 + IRR)ᵗ, for t = 1…5
Annual spacing
Every receipt occurs at an exact year-end measured from the initial investment.
Residual value
If included in the final receipt, the result is an interim marked return, not fully realized performance.
Total loss
All receipts zero is displayed as a −100% loss convention; no finite NPV root exists.
03 / A WORKED EXAMPLE

Put the numbers in context.

An initial $1,000,000.00 outflow followed by $200,000.00, $300,000.00, $300,000.00 and $1,500,000.00 at years two through five returns 2.3× in total. The solver discounts each receipt from its own year, rather than treating all proceeds as a year-five exit.

MODEL BOUNDARIES

What this calculation assumes

Exactly annual spacing, one initial outflow, nonnegative subsequent receipts and no later capital calls. Uses monotone bisection in log(1+r) space. This is periodic IRR, not actual-date XIRR. Zero receipts use an explicit total-loss convention.

FROM UNDERSTANDING TO ACTION

What to consider next.

Use the two-cash-flow annualized return only when all value arrives at one exit. For actual fund reporting, calculate from the full dated contributions and distributions.
