Will you please help a non-mathematician?

Please be gentle, I'm not a mathematician.

Solving the below equation for all variables, except i, works
satisfactorily. Trying to solve for i produces the following result.

in[1] Solve[0==PV+PMT*((1-(1+i)^-n)/i)+FV*(1+i)^-n,i]

Solve::tdep: 
   The equations appear to involve transcendental functions of
    the variables in an essentially non-algebraic way.

out[1] Solve[0 == FV/(1 + i)^n + ((1 - (1 + i)^(-n))*PMT)/i + PV, i]

Can someone tell me how to get Mathematica to solve for i?

Thank you for any help.

	Don
