Calculate Discounted Cash Flow
Calculate Discounted Cash Flow: Discounted Cash Flow (DCF) is a financial valuation method used to estimate an investment's value based on its future cash flows. By calculating the present value of expected future cash flows using a discount rate, investors can determine if an investment is undervalued or overvalued. It helps in making informed decisions about business investments, stock purchases, or project feasibility by considering the time value of money and risk factors.

DCF Formula
NPV = Σ [Cash Flow / (1 + r)^t] - Initial Investment
Where: r = discount rate, t = time period
How to Use
Enter initial investment amount, annual cash flow, discount rate (usually WACC), and investment duration. Click calculate to get Net Present Value (NPV). Positive NPV indicates profitable investment.

Consider inflation and risk factors when choosing discount rate.
Derivation Process
The DCF method originated from the concept of time value of money, formalized by Irving Fisher in 1930. It combines present value calculations for multiple periods. Financial analysts developed it to compare investments with different cash flow patterns. The formula weights future cash flows by risk and opportunity cost. Modern finance theory expanded its use through CAPM and WACC calculations. Continuous refinement improved accuracy in corporate finance and equity valuation.
FAQs
What is the purpose of calculate discounted cash flow?
DCF analysis helps determine an investment's current value based on projected future cash flows. It accounts for the time value of money, recognizing that money today is worth more than the same amount in the future. Investors use it to assess business valuations, stock prices, and capital projects. By discounting future cash flows at an appropriate rate, it provides a framework for comparing different investment opportunities objectively.
How accurate is DCF calculation?
DCF accuracy depends on input quality. Cash flow projections and discount rate selection significantly impact results. While mathematically precise, it's sensitive to assumptions. Best used for stable businesses with predictable cash flows. Regular updates with actual performance data improve accuracy. Should be combined with other valuation methods for comprehensive analysis.
What discount rate should I use?
Typically use Weighted Average Cost of Capital (WACC) for companies. For personal investments, use expected return rate. Riskier investments require higher rates. Public companies often use 8-12%. Adjust based on market conditions and specific project risk. Consult financial data for industry averages.
Can DCF be negative?
Yes, negative NPV indicates the investment would lose money. It means present value of cash outflows exceeds inflows. Investors should reject negative NPV projects unless strategic considerations outweigh financial metrics. Always compare with hurdle rate and alternative investments.
What's the difference between DCF and NPV?
DCF refers to the valuation method, while NPV is the numerical result. NPV specifically calculates the difference between present value of cash inflows and outflows. DCF analysis uses NPV to determine viability. Both consider time value of money, but DCF encompasses the entire valuation process.
How many years should DCF cover?
Typically 5-10 years. Use explicit projections for 5 years, then terminal value. Shorter for volatile industries, longer for stable businesses. Match projection period to investment horizon. Beyond 10 years, forecasts become unreliable. Balance detail with predictability.
What are DCF limitations?
Relies on uncertain forecasts. Sensitive to input changes. Doesn't account for flexibility. Ignores market conditions. Complex calculations. Best for cash-generating assets. Less effective for startups. Requires financial expertise. Combine with scenario analysis for better insights.
Can DCF value startups?
Challenging due to uncertain cash flows. Use with caution. Focus on market potential rather than historical data. Apply higher discount rates. Include scenario analysis. Often supplemented with other methods like multiples or scorecard valuation. Best for mature startups with clear monetization paths.
