Final answer:

To find the monthly payment for a $1.2 million mortgage at a 1.95% annual interest rate over 20 years, the formula P = [rPv] / [1 - (1 + r)^(-n)] is used. The resulting monthly payments are approximately $6347.40.

Step-by-step explanation:

To calculate the monthly repayments for a $1.2 million mortgage with a yearly interest rate of 1.95% over 20 years, we can use the formula for an amortizing loan monthly payment:


P = [rPv] / [1 - (1 + r)^(-n)]

Where:
P is the monthly payment
r is the monthly interest rate
Pv is the loan principal (initial amount borrowed)
n is the total number of payments (months)

First, we convert the annual interest rate to a monthly rate by dividing by 12 months:

Monthly interest rate = 1.95% / 12
Monthly interest rate = 0.1625%

Now, to convert the percentage to a decimal we divide by 100:

Monthly interest rate (decimal) = 0.001625

Next, we calculate n, the total number of payments:

n = 20 years * 12 months/year
n = 240 months

Now we can use the formula:

P = [0.001625 * 1200000] / [1 - (1 + 0.001625)^(-240)]
P = 6347.4049

Round off to nearest cent:

Monthly payment = $6347.40

Mortgages are calculated using simple interest, so:


A=P(1+rt)

P= principal amount

r= interest rate

t= time

For P=1.2mill

r=1.95%

t=20years

The simple interest will be:


A=1200000(1+0.0195\cdot20)=1668000

Now divide the calculated amount by 20 to get the yearly fee:


(1668000)/(20)=83400

And finally divide it by 12 to get the monthly fee:


(83400)/(12)=6950

The exercutive will pay 6950 monthly
