If a business generates cash flow as follows:

End of year 1: Rp. 100,000,000 End of year 2: Rp. 200,000,000 End of year 3: Rp. 250,000,000 End of year 4: Rp. 350,000,000 End of year 5: Rp. 450,000,000 End of the 6th year onwards (forever): the cash flow increased from the 5th year cash flow by 4% per year.

What is the value of the above business today (present value), if the opportunity cost (cost of capital) is 10%? Explain the calculation!
