From 7 to 12 months, you can bank 100% of your point.
From 4 to 6 months, if you still have points to bank, you can bank up to 50% of your total points.
3 months out, if you still have points to bank, you can bank up to 25% of your points.
2 months or less, you can't bank any more.
Banking percentages are based on the total annual allotment of Vacation Points regardless of the number of Vacation Point banked at any given time for any given Use Year. That means, in Nov, you can bank up to 125 points total. So you could only bank 87 more points, like Donald is #1 said.
You could go ahead and bank all of them. Then if you decide to take a trip towards the end of your UY, you could borrow from the next year.
