IRR Calculator (Newton method)
Internal rate of return solver using Newton-Raphson iteration. Identifies multiple IRRs where applicable (non-conventional cash flows). Returns base IRR + MIRR option.
Inputs
- initial investment
- cash flows year 1-20
- reinvestment rate (for MIRR)
Outputs
- IRR %
- MIRR %
- multiple-IRR warning if applicable
Methodology
Newton-Raphson: r_{n+1} = r_n - f(r_n)/f'(r_n) where f(r) = NPV. MIRR uses reinvestment-rate adjustment.
Formula:
0 = Σ CF_t / (1+IRR)^t - I_0Need this applied to your trade?
