Yup,
that's the calculator I use too.
Don't forget that you can tin the trace and make it thicker or lay a
copper wire on it and tin that and make a fat trace. Also, some
people use both the top and bottom of the board for beefing up power
traces.
I did a stepper motor driver and used a second board, kinda like a
home-brew 4 sided board and ran huge pins to connect the two boards.
