The Present Value of Interest Factor Annuity (PVIFA) is calculated using the formula: PVIFA = (\frac{1 - (1 + i)^{-n}}{i}), where (n) is the number of periods and (i) is the interest rate per period. For (n = 3) and (i = 3%) (or 0.03), the PVIFA can be computed as PVIFA = (\frac{1 - (1 + 0.03)^{-3}}{0.03}). This results in a PVIFA value that can be used to determine the present value of an annuity receiving equal payments over three periods at a 3% interest rate.
