Key Features of the Sharp EL-738
The Sharp EL-738 distinguishes itself through several advanced features that set it apart from basic calculators:
- Time Value of Money (TVM) Calculations: The cornerstone of financial mathematics, allowing users to calculate present value (PV), future value (FV), interest rate (I%), number of periods (N), and payment amounts (PMT).
- Cash Flow Analysis: Enables the calculation of Net Present Value (NPV) and Internal Rate of Return (IRR) for uneven cash flow streams, which is crucial for capital budgeting decisions.
- Amortization Schedules: Generates complete payment schedules for loans, showing the breakdown between principal and interest for each payment period.
- Depreciation Calculations: Supports multiple depreciation methods including straight-line, declining balance, and sum-of-years digits.
- Bond Valuation: Calculates bond prices and yields, accommodating various compounding periods and day count conventions.
- Statistical Functions: Includes mean, standard deviation, and other statistical measures for data analysis.
- Cost-Sell-Margin Calculations: Useful for business applications to determine pricing strategies and profit margins.
- Memory Functions: Allows storage and recall of values, enhancing efficiency for complex, multi-step calculations.
Understanding Time Value of Money (TVM) on the EL-738
The Time Value of Money principle is fundamental to financial mathematics, asserting that money available today is worth more than the same amount in the future due to its potential earning capacity. The Sharp EL-738 excels in TVM calculations through its dedicated financial keys:
- N (Number of Periods): Represents the total number of compounding periods.
- I% (Interest Rate per Period): The interest rate for each compounding period.
- PV (Present Value): The current worth of a future sum of money.
- PMT (Payment): The payment amount per period in an annuity.
- FV (Future Value): The value of a current asset at a future date based on an assumed growth rate.
To perform a TVM calculation, you typically input four known values and solve for the fifth unknown. The calculator uses the following standard formulas:
Future Value of a Single Sum: FV = PV × (1 + i)n
Present Value of a Single Sum: PV = FV / (1 + i)n
Future Value of an Annuity: FV = PMT × [((1 + i)n – 1) / i]
Present Value of an Annuity: PV = PMT × [1 – (1 + i)-n] / i
Cash Flow Analysis Capabilities
The EL-738’s cash flow functions are particularly valuable for evaluating investment opportunities. The calculator can handle up to 24 uneven cash flows, making it suitable for complex investment scenarios. Key applications include:
- Net Present Value (NPV): Calculates the present value of all future cash flows (both positive and negative) over the entire life of an investment, discounted at a specified rate.
- Internal Rate of Return (IRR): Determines the discount rate that makes the NPV of all cash flows (both positive and negative) equal to zero. IRR is often used to evaluate the attractiveness of a project or investment.
- Modified Internal Rate of Return (MIRR): Addresses some of the problems with IRR by assuming that positive cash flows are reinvested at the firm’s cost of capital, and the initial outlays are financed at the firm’s financing cost.
The cash flow analysis process on the EL-738 involves:
- Clearing previous cash flow data (using the CF key followed by 2nd and CLR)
- Entering each cash flow amount with its corresponding frequency
- Specifying the discount rate (for NPV calculations)
- Executing the calculation to determine NPV, IRR, or MIRR
Loan Amortization Functions
The amortization features of the Sharp EL-738 are extensively used in both personal and corporate finance for:
- Creating payment schedules for mortgages
- Structuring business loan repayments
- Analyzing lease payments
- Evaluating different financing options
The calculator can generate complete amortization tables showing:
- Payment number
- Payment amount
- Principal portion of the payment
- Interest portion of the payment
- Remaining balance
To create an amortization schedule, you would:
- Enter the loan amount (PV)
- Input the annual interest rate (converted to periodic rate)
- Specify the loan term in years (converted to number of periods)
- Calculate the regular payment amount
- Use the AMORT function to generate the schedule
Depreciation Calculations
The EL-738 supports several depreciation methods that are essential for accounting and tax purposes:
| Method | Description | When to Use | EL-738 Function |
|---|---|---|---|
| Straight-Line | Equal depreciation each year over the asset’s useful life | When asset provides equal benefits each year | SL |
| Declining Balance | Higher depreciation in early years, decreasing over time | When asset is more productive in early years | DB |
| Sum-of-Years Digits | Depreciation based on the sum of the asset’s useful life digits | When asset’s productivity declines over time | SYD |
| Units of Production | Depreciation based on actual usage or production | When asset’s wear is tied to usage | Requires manual calculation |
To calculate depreciation using the EL-738:
- Enter the asset’s initial cost
- Input the salvage value
- Specify the useful life in years
- Select the appropriate depreciation method
- Calculate the annual depreciation amount
Bond Valuation Features
The bond valuation functions on the Sharp EL-738 are particularly useful for fixed income investors and portfolio managers. The calculator can determine:
- Bond price given market yield

- Duration and convexity measures
Key bond calculation parameters include:
- Settlement date
- Maturity date
- Coupon rate
- Market yield
- Coupon frequency
- Day count convention
The bond price formula implemented in the EL-738 is:
Price = Σ [C / (1 + y)t] + F / (1 + y)n
Where:
- C = coupon payment
- y = yield per period
- t = time period
- F = face value
- n = total number of periods
