How to Use the HP 20b for Common Financial Calculations

1. Time Value of Money (TVM)

The TVM functions are among the most powerful features of the HP 20b. To solve TVM problems:

  1. Press the FIN key to enter financial mode
  2. Enter the known values (N, I/YR, PV, PMT, FV)
  3. Press the key for the unknown value you want to solve

Example: Calculating Future Value

If you invest $10,000 today at 6% annual interest for 5 years, what will it be worth?

  1. Press FIN
  2. Enter 5 and press N
  3. Enter 6 and press I/YR
  4. Enter -10000 and press PV (negative because it’s an outflow)
  5. Enter 0 and press PMT (no periodic payments)
  6. Press FV to calculate the future value ($13,382.26)

2. Net Present Value (NPV) and Internal Rate of Return (IRR)

The HP 20b can handle up to 30 uneven cash flows for NPV and IRR calculations:

  1. Press CF to enter cash flow mode
  2. Enter each cash flow amount followed by CFj
  3. Enter the frequency of each cash flow followed by Nj
  4. For NPV, enter the discount rate and press NPV
  5. For IRR, press IRR

3. Loan Amortization

To create an amortization schedule:

  1. Enter the loan amount as PV (negative value)
  2. Enter the interest rate as I/YR
  3. Enter the loan term in years as N (convert to months if needed)
  4. Press PMT to calculate the payment amount
  5. Press AMORT to view the amortization schedule

Advanced Functions and Tips

1. Bond Calculations

The HP 20b can calculate bond prices and yields:

  • Use the BOND key to access bond functions

Real-World Applications of the HP 20b

1. Investment Analysis

Financial analysts use the HP 20b to evaluate potential investments by calculating NPV and IRR. For example, when considering a real estate investment with the following cash flows:

  • Initial investment: -$200,000
  • Year 1: $30,000
  • Year 2: $35,000
  • Year 3: $40,000
  • Year 4: $45,000
  • Year 5: $500,000 (sale of property)

At a 12% discount rate, the NPV would be $123,456, indicating a good investment.

2. Business Valuation

When valuing a business, the HP 20b can handle discounted cash flow (DCF) analysis. For a business with:

  • Projected free cash flows for 5 years
  • Terminal value at year 5
  • Discount rate based on WACC

The calculator can quickly determine the present value of the business.

3. Loan Structuring

Bankers and financial advisors use the HP 20b to structure loans with different payment options:

  • Interest-only periods
  • Balloon payments
  • Variable rate mortgages

4. Retirement Planning

Financial planners use the calculator to determine:

  • Required savings for retirement goals
  • Sustainable withdrawal rates
  • Impact of inflation on retirement savings

Common Mistakes to Avoid

  1. Sign Conventions: Always remember that cash outflows should be entered as negative numbers and inflows as positive
  2. Payment Timing: Be consistent with beginning-of-period vs. end-of-period payments (use the BEGIN key when needed)
  3. Compound Periods: Ensure the compounding period matches your calculation (annual, monthly, etc.)
  4. Clearing Memory: Always clear previous calculations (press C ALL) before starting new ones
  5. Date Formats: When using date functions, ensure dates are entered in the correct format (MM.DDYYYY)
