This is the well known Gordon Growth model used for stock valuation. The future value (after "n" periods) of an annuity (FVA) formula has four variables, each of which can be solved for by numerical methods: To get the FV of an annuity due, multiply the above equation by (1 + i). The future value (after "n" periods) of a growing annuity (FVA) formula has five variables, each of which can be solved for by
