A Discounted Cash Flow (DCF) model is a valuation method used to estimate the value of an investment based on its expected future cash flows. The core principle is that money available today is worth more than the same amount in the future due to its potential earning capacity. 

### Steps to Create a DCF Model

1. **Forecast Free Cash Flows (FCF)**:
   - Estimate the cash flows the business will generate over a specified period (typically 5-10 years). FCF can be calculated as:
     \[
     \text{FCF} = \text{Operating Cash Flow} - \text{Capital Expenditures}
     \]

2. **Determine the Discount Rate**:
   - This is usually the Weighted Average Cost of Capital (WACC), reflecting the risk of the investment. It can be calculated using:
     \[
     WACC = \frac{E}{V} \cdot r_e + \frac{D}{V} \cdot r_d \cdot (1 - T)
     \]
   where $E$ = market value of equity, $D$ = market value of debt, $V$ = $E + D$, $r_e$ = cost of equity, $r_d$ = cost of debt, and $T$ = tax rate.

3. **Calculate the Present Value (PV) of Cash Flows**:
   - Discount future cash flows back to the present value using the discount rate:
     \[
     \text{PV} = \frac{\text{FCF}_1}{(1 + r)^1} + \frac{\text{FCF}_2}{(1 + r)^2} + \ldots + \frac{\text{FCF}_n}{(1 + r)^n}
     \]

4. **Estimate the Terminal Value (TV)**:
   - This accounts for cash flows beyond the forecast period, typically using a perpetuity growth model:
     \[
     \text{TV} = \frac{\text{FCF}_n \times (1 + g)}{r - g}
     \]
   where $g$ is the growth rate after the forecast period.

5. **Calculate Total DCF Value**:
   - Sum the present values of the forecasted cash flows and the present value of the terminal value.

### Example

**Assumptions**:
- Year 1 FCF: $100,000
- Year 2 FCF: $120,000
- Year 3 FCF: $150,000
- Year 4 FCF: $180,000
- Year 5 FCF: $200,000
- Terminal growth rate (g): 3%
- Discount rate (WACC): 10%

**Calculations**:

1. **Present Values of Cash Flows**:
   - PV of Year 1: 
     \[
     \frac{100,000}{(1 + 0.10)^1} = 90,909.09
     \]
   - PV of Year 2: 
     \[
     \frac{120,000}{(1 + 0.10)^2} = 99,173.55
     \]
   - PV of Year 3: 
     \[
     \frac{150,000}{(1 + 0.10)^3} = 112,697.04
     \]
   - PV of Year 4: 
     \[
     \frac{180,000}{(1 + 0.10)^4} = 123,129.12
     \]
   - PV of Year 5: 
     \[
     \frac{200,000}{(1 + 0.10)^5} = 124,352.43
     \]

2. **Terminal Value Calculation**:
   - TV = 
     \[
     \frac{200,000 \times (1 + 0.03)}{0.10 - 0.03} = 2,914,285.71
     \]
   - Present Value of TV:
     \[
     \frac{2,914,285.71}{(1 + 0.10)^5} = 1,815,125.45
     \]

3. **Total DCF Value**:
   - Total PV = Sum of all PVs + PV of Terminal Value:
   \[
   90,909.09 + 99,173.55 + 112,697.04 + 123,129.12 + 124,352.43 + 1,815,125.45 = 2,365,386.68
   \]

### Conclusion
The DCF model estimates the present value of a business at approximately $2,365,387 based on the projected cash flows and terminal value.
