CALCULATION DESK
Find a rate that makes the net present value of a comma-separated sequence of periodic cash flows approximately zero.

BATCH / ONE VALUE PER LINE
Up to 200 lines, one at a time, in this browser. Each line takes the place of cashflows and everything else stays as you set it. Nothing is uploaded, and the row limit is not exceeded silently.
METHOD / LOCAL RUN
A bounded bisection search solves for the periodic rate at which Σ cash flow at period t ÷ (1 + rate)^t is approximately zero.
Boundary: Multiple or no IRRs can exist. This utility returns one bounded numerical estimate and is not a valuation, investment recommendation, or cash-flow verification.
The calculation or transformation runs in your browser using the values entered above. No input is sent to UtilityForge for this tool.

FAQ
Multiple or no IRRs can exist. This utility returns one bounded numerical estimate and is not a valuation, investment recommendation, or cash-flow verification.
No. This published tool runs locally in your browser. UtilityForge does not send the values entered in this workbench to a server.
No. The tool provides a calculation or transformation. Review material decisions with an appropriate professional source.
No. This workbench runs in the page: Cash flows, period 0 first are read by the code your browser already downloaded, and UtilityForge receives neither the values nor the result.
Yes, and it is enforced rather than advertised: Cash flows, period 0 first (10,000 characters). The limit is a browser input limit on a tool that runs on this device, so nothing is truncated after being sent anywhere.
