Step-1:Caluclation of monthly payment | ||||||||||||
Monthly payment | = | Loan amount / Present value of annuity of 1 | ||||||||||
= | $ 2,29,000 | / | 156.0935 | |||||||||
= | $ 1,467.07 | |||||||||||
Working: | ||||||||||||
Present value of annuity of 1 | = | (1-(1+i)^-n)/i | Where, | |||||||||
= | (1-(1+0.005525)^-360)/0.005525 | i | 6.63%/12 | = | 0.005525 | |||||||
= | 156.0935158 | n | 30*12 | = | 360 | |||||||
Step-2:Calculation of loan amount balance after 4 years | ||||||||||||
Loan amount is the present value of monthly payment. | ||||||||||||
Loan amount at the end of 4 years | = | Monthly payment * Present value of annuity of 1 | ||||||||||
= | $ 1,467.07 | * | 148.554686 | |||||||||
= | $ 2,17,940.01 | |||||||||||
Working: | ||||||||||||
Present value of annuity of 1 | = | (1-(1+i)^-n)/i | Where, | |||||||||
= | (1-(1+0.005525)^-312)/0.005525 | i | 6.63%/12 | = | 0.005525 | |||||||
= | 148.5546858 | n | 26*12 | = | 312 | |||||||
Step-3:Calculation of repayment of principal | ||||||||||||
Repayment of principal | = | Loan amount at the beginning | - | Loan amount after 4 years | ||||||||
