Question

The interest factor (IF) for the future value of an ordinary annuity is 4.641 at 10% for four years. If we wish to accumulate $8,000 by the end of four years, how much should the annual payments be?

Answer 1

$ 1,723.76

Step-by-step explanation:

Given:

Interest factor = 4.641

Rate of interest, r = 10%

Future value of the annuity = $ 8,000

Now,

The future value of annuity is calculated as

=
`P*(((1+r)^n-1)/(r))`

Where,

P = Principal payable

r = interest rate

n = number of payments

thus, on substituting the values, we get

$8,000 = P × Interest factor

or

$ 8,000 = P × 4.641

or

Annual payment, P = $ 1,723.76
