The difference can be as follows :
equal annual installments are the amounts of money payable or paid every year ...... It is arrived by dividing the amount of the loan along with the interest with the period of loan .......
E.g.loan amount = 10,000 and interest as rs.2000....the total amount of rs. 12000 is divided by the period say 4 years ....so equal annual installment would be 3,000...........
Equated annual installments are also amounts of money payable or paid every year ..however equated annual installments are arrived after dividing the loan amount along with the interest with the interest rate present value annuity factor ....
E.g loan Amount =10,000 and interest amount =2,000.....
Total amount = 12,000... And interest rate is 10 % n period as 4 years
The amount of rs.12000 shall be divided by present value annuity factor to arrive at equated annual installment....
.i.e 12,000/ 3.169= rs 3787
Ok..........
