Assumed Lift height

Ok i know someone will direct me where to look... but i am looking to get a 6" lift with 33" tires on my new 2013 Tacoma prerunner. my question is, what is the total height in inches that this will increase the truck? I need to be sure i can still get the truck into the garage.
Can i safely assume that if take the current height + lift + increase in tire size, this will give me rough height +/- ?

in theory:
Current height of - 70"
+6" lift = 76"
+2" tire increase = 78"

Is 78" a safe assumption or is the lift and tire sizes subjective?

Tire size increase is only 1/2 the difference. 30.5" to 33" = 1.25" in lift.
