If your fitting curve depends on time t, evaluate it at the future time instant you have in mind.
But be very,very careful here:
Extrapolation of trend curves is extremely error-prone. Especially polynomial curves of degree greater 1 usually don't reflect the physical or economical background where the data stem from and are therefor only suited to interpolate between the time limits of your data.
