$FV = \dfrac{(1+i)^t-1}{i}\cdot C$
What are the algabraic steps I need to rearrange to get i? The i divided by the i is specifically tripping me up.
Many thanks!

In general, given $C$, $\text{FV}$, and $t$, we have $$\dfrac{\text{FV}}{C}i=(1+i)^t-1$$ or $$1=\dfrac{\text{FV}}{C}i+(1+i)^t\text{.}$$ There is no way to write a (simple) formula for $i$ in this case for general $t$. Usually what is done is assuming you have the three variables, you would use a financial calculator, such as a BA-II+, to solve for $i$.
