How is the Internal Rate of Return (IRR) computed?

The Internal Rate of Return (IRR) takes into account the effect of compounded earnings (e.g. assumes income on the investment is reinvested at a constant rate). In the case of an initial investment of $100,000 which is worth $120,000 after one year, the IRR would be approximately 18.25% while the simple return would be 20%.
