This tool calculates the internal rate of return for a series of cash flows to help you evaluate the profitability of your investments.

## How to Use the XIRR Calculator

Enter your cash flows and their corresponding dates into the fields. Cash flows should be specified as comma-separated values. Use negative values for outflows and positive values for inflows. The dates must follow the format YYYY-MM-DD and be comma-separated as well.

## Explanation of the Calculation

The XIRR (Extended Internal Rate of Return) is a financial metric used to calculate your return on investment when cash flows are irregular. It is particularly useful for investments that have multiple deposits and withdrawals over time.

## How It Calculates the Results

The script uses the Newton-Raphson method to approximate the XIRR. It iterates until it finds a rate that satisfies the XIRR equation within an acceptable level of accuracy.

## Limitations

This calculator does not handle cases where the XIRR method fails to converge. Ensure your date periods are appropriately spaced and your cash flows are correctly entered to maximize the accuracy of the results.
