Final answer:
To calculate the monthly payment, total interest, and present value, one would use the PMT and PV functions with appropriate formulas, incorporating the loan's interest rate, term, and amount into the respective calculations.
Step-by-step explanation:
To answer the first question, you would enter the following formula in cell F5 to calculate the monthly payment using the PMT function:
=-PMT(Rate/12, Term*12, Loan_Amount)
For the loan specified, assuming Rate is 6%, Term is 30 years, and Loan_Amount is $300,000, the PMT function will calculate the payment per month.
To answer the second question, in cell F6, the formula to calculate the total interest paid over the loan period without using a function would be:
=12*Term*Monthly_Payment - Loan_Amount
Given the Term is 30 years, Monthly_Payment is the result from F5, and Loan_Amount is $300,000, this formula gives you the total interest paid over the life of the loan.
Finally, to answer the third question, in cell J5 you would enter the following formula using the PV function:
=PV(Rate/12, (Term - Year_H5)*12, -Monthly_Payment)
Here, Rate is still 6%, Term is 30 years, Monthly_Payment would be the same as before but entered as a negative because it's a payment, and Year_H5 refers to the value in cell H5 which indicates the number of years already paid on the loan.
