Fixing deficit for To Be Budgeted next month
I am 1 month buffered on YNAB. When looking at August, I see a $500-ish deficit between what I have in Income for next Month in July, and the negative TBB value for August.
What does this mean? Does it simply means what I think it does? If so, what is the best way to fix the deficit, and in which month should I do it?
