IRR Calculator

Calculate Internal Rate of Return for investments and projects

IRR Calculator

Internal Rate of Return (IRR)

The discount rate that makes the Net Present Value (NPV) of cash flows equal to zero. Enter your cash flows to calculate IRR, NPV, and payback period.

Advanced Analysis

Multiple IRR & MIRR

Analyze projects with multiple IRRs and calculate Modified Internal Rate of Return (MIRR) for more reliable results.

IRR Analysis Results

Formulas Used
IRR: Rate where NPV = 0, or Σ[CFt / (1 + IRR)^t] = 0
NPV: Σ[CFt / (1 + r)^t] - Initial Investment
MIRR: ((FV of positive cash flows / PV of negative cash flows)^(1/n)) - 1
Payback Period: Time required to recover initial investment

Key Features:

  1. IRR Calculation—Internal Rate of Return using Newton-Raphson method
  2. Multiple Input Methods—Manual entry and bulk input options
  3. Advanced Analysis—XIRR for irregular cash flows and time-based analysis
  4. Comprehensive Metrics—NPV, MIRR, payback period, profitability index
  5. Sensitivity Analysis—NPV at different discount rates
  6. Cash Flow Tables—Detailed breakdown with present values
  7. Time-Based Analysis—Handle irregular time periods with dates

Calculations Include:

  • IRR: Rate where NPV equals zero
  • XIRR: IRR for irregular time periods
  • MIRR: Modified IRR with different reinvestment assumptions
  • NPV: Net Present Value at specified discount rate
  • Payback Period: Time to recover initial investment
  • Discounted Payback: Payback period considering time value of money
  • Profitability Index: Ratio of PV of future cash flows to initial investment

Analysis Types:

  • Standard IRR: Regular periodic cash flows
  • Advanced XIRR: Irregular cash flows with specific dates
  • Multiple IRR Detection: Identifies projects with multiple IRRs
  • Sensitivity Analysis: Shows NPV sensitivity to discount rate changes

The calculator handles complex scenarios like multiple IRRs irregular cash flows and provides comprehensive investment analysis metrics used by financial professionals.
