Default wheel and offset question

I'm trying to calculate some measurements whan changing wheels and offsets. If i have 20x10 wheels with a 45 offset and switching to a 20x11 with 15 offset, would i be correct to say it will push out the wheel away from the car by this amount:

From 10" to 11" is a difference of 1" so it would be 1/2 to the inside of the car and 1/2 to the outside

from a 45 offset to 15 offset is a difference of 30mm which is roughly 1.2" to the ouside

so adding these together it should push the wheel 1.45" out more away from the car compared to the 10"/45 offset. Trying to find out if a 15 offset on a 11" wide wheel would require pulling fenders or just shaving the lip.

Thanks in advance and post pictures if you have any wheel setup close to what i'm trying to fit (20x11 with 15 offset). By the way it will be going on a gs 450h

1.7 inch difference, the idea is right, math is wrong.

Gotta pull. My buddy did 10.5 +18 and cut alone didn't do.

avoid cutting fenders (unless you plan to pull them) they will only cause problems later down the road.

And you will most likely need to roll your fenders. Stretch+Camber+Roll is what allows for maximum clearance to avoid rubbing. Basically any car thats flush utilizes those three things.
