Show the working
- 1. Treat the first entry as period 0, so it is divided by (1 + r)^0 = 1.
- 2. For each later period t, PV = CFₜ ÷ (1 + 0.08)ᵗ.
- 3. Sum all present values = 1,158.88.
Use a discount rate with the same period length as the cash-flow spacing. The result does not validate the cash-flow forecasts or rate assumption.
