Valuation expert specializing in Discounted Cash Flow (DCF) models and complex capital budgeting techniques.
The **Discounted Cash Flow (DCF) Calculator** estimates the value of an investment based on its expected future cash flows. By discounting these future flows back to their present value, you can determine the investment’s intrinsic worth today. This version uses a simplified **constant annual cash flow (annuity)** model for calculation. Enter values for any three of the four core parameters (Annual Cash Flow, Discount Rate, Number of Years, or Total DCF Value) to solve for the missing one.

DCF Parameters (Annuity Model)
DCF Formula (Annuity)
When cash flows ($CF$) are constant, the DCF is the Present Value of an Ordinary Annuity:
Total DCF Value ($PV_{total}$):
$$PV_{total} = CF \times \frac{1 – (1 + R)^{-N}}{R}$$ Formula Source: Investopedia (DCF)Variables Explained (P, F, V, Q – Parameters)
- $CF$ (Annual Cash Flow, $P$): The constant, expected net cash flow received each year.
- $R$ (Discount Rate, $F$): The rate used to determine the present value of future cash flows (Cost of Capital).
- $N$ (Number of Years, $V$): The duration over which the cash flows are projected.
- $PV_{total}$ (Total DCF Value, $Q$): The present value of all future cash flows. (Calculated Value)

What is Discounted Cash Flow (DCF)?
The **Discounted Cash Flow (DCF)** method is a valuation technique used to estimate the attractiveness of an investment opportunity. It relies on the principle that the value of an asset is equal to the present value of all the future cash flows that asset is expected to generate. By “discounting” future cash flows, the model accurately reflects the time value of money—the fact that a dollar received in the future is worth less than a dollar received today.
DCF is widely considered the most theoretically sound method for stock, business, and project valuation. The key challenge lies in accurately projecting future cash flows and selecting an appropriate discount rate (often the Weighted Average Cost of Capital, WACC). If the calculated DCF value is higher than the investment’s current cost, the investment is generally considered worthwhile.
How to Calculate DCF (Example)
Assume a project that generates \$10,000 in Annual Cash Flow ($CF$) for 5 years ($N$), with a required Discount Rate ($R$) of 8%. We solve for the Total DCF Value ($PV_{total}$):
- Step 1: Convert Rate to Decimal
$R = 8\% / 100 = 0.08$.
- Step 2: Calculate the Annuity Discount Factor
$$Factor = \frac{1 – (1 + 0.08)^{-5}}{0.08} \approx 3.9927$$
- Step 3: Calculate the Total DCF Value
$PV_{total} = CF \times Factor = \$10,000 \times 3.9927 \approx \mathbf{\$39,927.10}$.
The **Total DCF Value** (Intrinsic Value) is $\mathbf{\$39,927.10}$.
Frequently Asked Questions (FAQ)
NPV (Net Present Value) calculates the DCF and then subtracts the Initial Investment. DCF calculates only the present value of the cash flows. If DCF > Initial Investment, then NPV > 0.
For company valuation, $R$ is typically the WACC (Weighted Average Cost of Capital). For personal investments, it could be your minimum required rate of return or the return you could get on a similar-risk investment (opportunity cost).
It is best because it explicitly incorporates the time value of money, the expected timing of cash flows, and a risk factor (the discount rate), making it more holistic and less prone to market volatility than simple ratio models.
This simplified calculator assumes constant annual cash flows (an annuity). For variable cash flows, you must calculate the present value of each individual year’s cash flow and sum them up (the traditional, more complex DCF method).
