Shifted Uniform Series Example 1 When we have shifted uniform series, then P can be determined by any of the following methods: [1] Use the P/F factor to find the present worth of each disbursement at year 0 and add them up [2] Use the F/P factor to find the future worth of each disbursement in year 13, add them, and then find the present worth of the total P=F(P/F,1,13) [3] Use the F/A factor to find the future amount F=A(F/A,1,10) and then compute the present worth using P=F(P/F,1,13) [4] Use the P/A factor to compute the present worth (located in year 3 not 0) and then find the present worth in year 0 by using the (P/F,1,3) factor | Year
