Discounted cash flow calculator for annual cash flows

Discounted cash flow formula

Each cash flow is discounted using Present value = Cash flow / (1 + r)t, where r is the discount rate and t is the year.

Why discounted cash flow matters

Two projects can have the same nominal total cash flow but different value if one receives cash earlier and another receives cash later. Discounted cash flow analysis makes that difference explicit.

Choosing an appropriate discount rate

The discount rate should reflect the investment’s risk profile and the cost of capital required to fund it. In practical investment banking work, the rate is a disciplined way of asking whether an engineering or infrastructure project earns enough return for the capital, execution risk, operating risk, market exposure, and time delay involved.

Higher-risk investments should generally be tested with higher discount rates because their forecast cash flows are less certain. Where capital is limited, the discount rate can also operate as a hurdle rate: projects that cannot clear that risk-adjusted return threshold are screened out so scarce capital can be directed to opportunities with stronger expected pay-off.
