XIRR Estimate (Two Cash Flows) formula
This version annualizes one starting investment and one later value using the exact elapsed days. A full XIRR calculation supports multiple irregular positive and negative cash flows.
How to interpret the result
Use this result only for a two-cash-flow scenario. Do not compare it with portfolio XIRR where there are multiple investments or withdrawals.
Worked example
An investment growing from 10,000 to 13,000 over exactly two years has an annualized return of about 14.02%. This is a two-cash-flow estimate, not a full multi-cash-flow XIRR.
How to use this calculator
- Enter values from the same transaction or scenario.
- Confirm that quantities, dates, rates and currency match the labels.
- Review the result and change one assumption at a time when comparing scenarios.
Common mistakes
- Calling a two-value annualized return a full portfolio XIRR.
- Entering an end date before the start date.
- Ignoring intermediate cash flows.
Limitations
The current tool is not a multi-cash-flow XIRR solver. It is retained at the existing URL but clearly labelled as a two-cash-flow estimate until expanded.
