George secured an adjustable-rate mortgage (ARM) loan to help finance the purchase of his home 5 years ago. The amount of the loan was $200,000 for a term of 30 years, with interest at the rate of 5%/year compounded monthly. Currently, the interest rate for his ARM is 4.5%/year compounded monthly, and George's monthly payments are due to be reset. What will be the new monthly payment?

To calculate George's new monthly payment after the interest rate adjustment, we follow these steps:

1. **Determine the original loan parameters:**
   - Original loan amount: $ P = 200,000 $
   - Original interest rate: $ r = 5\% \text{ per year} = \frac{5}{12} \% \text{ per month} $
   - Original loan term: 30 years, which is $ 30 \times 12 = 360 $ months.

2. **Calculate the remaining balance after 5 years:**
   - After 5 years, George has made $ 5 \times 12 = 60 $ payments. We need to find the remaining balance on the loan after these 60 payments using the formula for the balance on a loan:
   
   \[
   B = P \times \left( \frac{(1 + r)^N - (1 + r)^n}{(1 + r)^N - 1} \right)
   \]
   Where:
   - $ B $ is the remaining balance.
   - $ N $ is the original number of payments (360 months).
   - $ n $ is the number of payments already made (60 months).
   - $ r $ is the monthly interest rate.

3. **Use the new interest rate to calculate the new monthly payment:**
   Once the remaining balance is determined, we will use the updated interest rate of $ 4.5\% $ compounded monthly to calculate the new payment.

Let me calculate the result for you.The new monthly payment for George, based on the adjusted interest rate of 4.5%, will be approximately **$1,020.83**.
