If you are doing PVA & FVA problems, what difference does it make if the annuities are "annuities due" or "ordinary annuities"?
In FVA or a PVA of annuity due problems, annuity payments earning interest one period sooner than in ordinary annuity problems. Thus, higher FVA and PVA values result along with an annuity due. The first payment occurs sooner in the case of future value of annuity due. In present value of annuity due problems, each of annuity payment take place one period sooner, so the payments are discounted less harshly.
