Answer: $2,025
Explanation:
Your monthly payment based on the rate of 6.3% per annum is:
= (6.3% * 1,620,000 ) / 12 months
= 102,060 / 12
= $8,505
Now that the rate has gone up to 7.8% per annum, the payment is:
= (7.8% * 1,620,000 ) / 12 months
= 126,360 / 12
= $10,530
Payment went up by:
= 10,530 - 8,505
= $2,025
