• Second Function: Many keys have a second function, indicated above the key. Press 2e F then the desired key to access its second function.

Financial Functions (TVM)

The calculator is equipped with Time Value of Money (TVM) functions for financial calculations. The primary TVM keys are N (number of periods), I/Y (interest rate per year), PV (present value), PMT (payment), and FV (future value).

3. Calculating Unknown: After inputting at least four of the five TVM variables, press the key for the unknown variable to calculate its value. For example, to find PMT, input N, I/Y, PV, FV, then press PMT.

Amortization Calculation

To calculate amortization schedules, use the AMRT function. This typically follows a TVM calculation where a loan is defined.

Cash Flow Analysis (NPV, IRR)

The calculator supports cash flow analysis using Net Present Value (NPV) and Internal Rate of Return (IRR). Use the CFi (Cash Flow Input) and COMP (Compute) keys in conjunction with the VAN et TRI functions (accessed via 2e F).

• STO: Stores the displayed value into a specific memory register.
• M-CLR: Clears the independent memory (likely 2e F + M-CLR).
