Voltage drop for aluminum wire to detached garage
Going only 130 feet, you do not need to up-size wire for voltage drop. The usual #1 Al will suffice for 100A breaker.  

Any plan requires a 125% derating of the expected load.  For instance, if you actually intended to pull 100A as a regular, frequent load, you would need  125A to be provisioned, i.e. A 125A breaker and wire.  By extension, the 100A breaker is sized to support 80A of frequent load.  

Now there are a couple ways those voltage drop calc's get you. #1 is they prod you for the breaker value, not the practical load - 100A not 80A.  You should enter 80A.    #2 is that they are rather obsessed with 3% as a "very hard maximum" possible voltage drop.  That's not supported by Code; Code wants to see 8% among all voltage drops.   Definitely use a number larger than 3%, like 5-6%, and see what the result is.  Very often, you find the actual number works out to 3.34% or something, and it's just not worth paying a lot more over 0.34%. 

By my math, 4/0 aluminum would support a 200A feed breaker.  However, it will not fit on a 100A feed breaker.
