To calculate your monthly mortgage payment, you would use the PMT function.
Option A) PMT - This option is correct because the PMT function in finance calculates the monthly payment for a loan or mortgage. It takes into account the principal amount, interest rate, and loan duration.
Option B) NPER - This option is incorrect because the NPER function calculates the number of periods required to pay off a loan or investment. It does not calculate the monthly payment amount.
Option C) NV - This option is incorrect because there is no such function as NV in finance. It does not calculate the monthly mortgage payment.
Option D) PV - This option is incorrect because the PV function calculates the present value of a future payment or investment. It does not calculate the monthly mortgage payment amount.
Therefore, the correct answer is option A) PMT.
