Six Functions of a Dollar

A few people have written to inquire about the Six Functions of a Dollar. Hey - after I looked up what they were talking about I thought I would throw together a few formulas to show how excel can do this.

The basic starting thought is what happens to one dollar under different scenarios.

Typically it is set up at a 5 year period (which would be 60 months - I have in E2) at a certain interest rate - lets say 10% (which in excel would be best described as .10 - I have in E3).

  math excel answer
amount of $1
=(1+E3)^E2 =FV(E3,E2,0,-1)

304.48164

amount of $1 per period
=(((1+E3)^E2)-1)/E3 =FV(E3,E2,-1,0) 3034.8164
sinking fund factor
=E3/(((1+E3)^E2)-1) = PMT(E3,E2,0,-1) 0.0003295
present worth of $1
=(1/((1+E3)^E2)) =PV(E3,E2,0,-1) 0.0032842
present worth of $1 per period
=(1-(1/(1+E3)^E2))/E3 =PV(E3,E2,-1,0) 9.9671573
partial payment
=E3/(1-(1/(1+E3)^E2)) =PMT(E3,E2,-1,0) 0.1003295
