Step-1:Calculation of monthly payment | |||||||||||||||
Monthly payment | = | Loan amount / present value of annuity of 1 | |||||||||||||
= | $ 3,00,000 | / | 216.6036 | ||||||||||||
= | $ 1,385 | ||||||||||||||
Working: | |||||||||||||||
Present Value of annuity of 1 | = | ((1-(1+i)^-n)/i)*(1+i) | Where, | ||||||||||||
= | ((1-(1+0.003125)^-360)/0.003125)*(1+0.003125) | i | 3.75%/12 | = | 0.003125 | ||||||||||
= | 216.6036 | n | 30*12 | = | 360 | ||||||||||
Step-2:Calculation of total payments made over the life of loan | |||||||||||||||
Total Payments over the life of loan | = | Monthly payment * Total number of months over the life of loan | |||||||||||||
= | $ 1,385 | * | 360 | ||||||||||||
= | $ 4,98,607 | ||||||||||||||
Step-3:Calculation of interest costs over the period of mortgage loan | |||||||||||||||
Total amount repaid over the life of mortage | $ 4,98,607 | ||||||||||||||
Less amount borrowed | $ 3,00,000 | ||||||||||||||
Interest Costs | $ 1,98,607 | ||||||||||||||
Thus, | |||||||||||||||
Total interest paid during the mortgage period | $ 1,98,607 | ||||||||||||||
