Explanation : Internal Rate of Return (IRR): The discount
rate on an investment that equates the present
value of the investment’s cash outflows with
the present value of the investment’s cash
inflows. For instance, if you spend $50,000
on a given investment, the IRR per cent would
be the annualized rate of return of the profit.
It’s not just the annual rate of return per year
multiplied by the number of years. If you loan
$50,000 and get no interest the first year, but
you get $20,000 in interest or return in the
second year, you actually got about $10,000
each year, so the IRR is approximately 20 per
cent.
