如何计算Modified I R R
learn.whatIsHeading
Modified IRR (MIRR) fixes IRR's reinvestment rate assumption by using explicit finance/reinvestment rates; often more realistic.
分步指南
- 1Input cash flows, finance rate (for negative CF), reinvestment rate (for positive CF)
- 2Calculate MIRR
- 3Compare to regular IRR
例题解析
输入
Standard IRR 25%, but reinvestment at 10%
结果
MIRR ≈ 18% (more realistic)
Avoids unrealistic assumptions
常见错误注意事项
- ✕Using same rate for finance and reinvestment
- ✕Not reflecting realistic opportunity costs
常见问题
Should I always use MIRR?
Yes if assumptions reasonable; more realistic than IRR for most projects.
