• Understanding Time Value of Money

    • Future cash flows need to be discounted to present value for accurate comparisons.
    • Net Present Value (NPV) helps evaluate different cash flow options by considering the time value of money.

  • Lottery Examples and Options

    • Lottery winnings may be presented as either lump sum or an annuity payment over years (e.g. $1 million over 30 years).
    • Options for payout:
    • Option 1: Lump sum today, e.g., $300,000.
    • Option 2: $20,000 annually for 30 years.
    • Option 3: $30,000 annually for 15 years.
    • Option 4: $100,000 today plus $15,000 annually for 30 years.
    • Option 5: $1 million after 30 years.

  • Choosing Between Lump Sum and Annuity

    • Factors influencing choice:
    • Immediate cash versus future cash.
    • Consider inflation rates and investment opportunities.
    • Immediate needs vs. long-term investment strategy.

  • Using Excel for Financial Models

    • Create spreadsheets to evaluate cash flows over time; important for analysis and decision-making.
    • Essential to format cash flow data correctly (currency, decimals).

  • Calculating Present Value and NPV

    • NPV = Present value of future cash flows - Initial investment.
    • Discount Rate: Must be established before calculating NPV; reflects opportunity cost and risk associated with cash flows.
    • Example: A 5% discount rate based on expected returns from a low-risk investment.

  • Setting Up NPV Calculation in Excel

    • Use the NPV function:
    • Syntax: =NPV(discount_rate, value1, [value2], ...)
    • Remember to include initial cash outlays separately, as NPV only considers future cash flows from the formula.

  • Comparison of Options

    • Calculate NPVs for each option under varying discount rates to value options correctly.
    • Higher rates decrease present value of future cash flows, affecting which option may seem most valuable today.

  • Importance of Financial Models

    • Helps visualize effects of choices on future cash returns.
    • Allows for adjustment based on new information (e.g., changes in discount rate).

  • Additional Considerations

    • Possible tax implications of lump sum vs. annuity payments (how much will be lost to taxation).
    • Consult a financial advisor for detailed analysis tailored to personal situation.

  • Practical Skills in Excel

    • Ability to build models to forecast and analyze financial outcomes.
    • Understanding database functions and data validation to maintain data integrity in analyses.
