About this Tool
Inspect dated inflows and outflows, calculate XIRR and XNPV, and export your schedule in your browser.
How it works
Uses actual elapsed days divided by 365 to discount dated cash flows. A bounded root search reports candidate XIRRs and flags nonconventional cash flows; it does not guarantee a unique return.
A practical way to use it
Compare a synthetic initial investment with later contributions and a final withdrawal.
Use results as a practical aid, and verify important decisions against your own source data and qualified guidance.
