XIRR Calculator

The XIRR Calculator computes the Extended Internal Rate of Return for a series of irregular cash flows and dates. Supports SIP investments, partial withdrawals, and lump sum redemptions with actual dates. It applies the standard formula: XIRR: Find rate r such that Σ [CF_i / (1+r)^((d_i − d_0)/365)] = 0.

Whether you are facing an important financial decision or simply need a fast, reliable answer, this calculator eliminates manual mathematical errors and delivers instant, accurate results. It is designed around verified industry standards and mathematical best practices, making it suitable for students, professionals, and everyday users alike.

Use the inputs above to enter your values — results update in real time. Below the result, you will find a step-by-step formula breakdown, a worked numerical example, and common mistakes to avoid. Note: XIRR requires at least one positive and one negative cash flow. Non-convergent cash flows will report an error instead of NaN.
