The minimum annual interest rate needed to create the perpetual cash flow stream of $10,000 with a present value of $200,000 is 5%.
A perpetuity is an annuity that continues for ever. To determine the interest rate, we divide the annuity $10,000 by the present value investment of $200,000 and then multiply by 100.
Present value of investment = $200,000
Annuity (yearly cash stream) - $10,000
Interest rate = 5% ($10,000/$200,000 x 100).
Thus, the interest rate needed to create the perpetual cash flow stream of $10,000 with a present value of $200,000 is 5%.
