1. Turn on the HP12C calculator.
2. Enter the present value (PV) as -10,000 (negative value indicates a loan).
3. Press the “FV” key and enter 0, as there is no future value in this scenario.
4. Press the “N” key and enter 5, representing the 5-year period.
5. Press the “CPT” key, then press the “I/Y” key.
6. The HP12C calculator will display the monthly interest rate as 0.4167% (0.004167 in decimal form).
