What is DCF?

Discounted Cash Flow (DCF) is a valuation method used to estimate the value of a business, investment, or project.

It works by forecasting future cash flows and adjusting them to today's value using the time value of money principle.

This reflects that money available today is worth more than the same amount in the future.

Why does DCF matter?

• Accounts for the time value of money.
• Supports project and company valuation.
• Enables comparison of investment opportunities.
• Improves financial decision-making.

• Choose a discount rate (usually WACC).
• Discount future cash flows to present value.
• Calculate terminal value.
• Sum all present values.
• Compare with investment cost.
• Perform sensitivity analysis.

Types of DCF

• FCFF: Values entire firm (debt + equity).
