It turns out putting the previous budgeted amounts (e.g. previously saved $400 in my Vacation category in 2018, budgeting an additional $100/month) isn’t rolling over month to month on the yearly view, so I can’t see what i have to available to spend in a given year, in terms of actual money, not just the projected annual budget. For September, I just see I have $100 in the vacation category that was budgeted in Sept. I don’t see that i have $400 left from earlier in the year, plus $100, available to spend anywhere. The yearly view shows $800 available, which assumes I keep budgeting exactly the same amount to that category for the rest of the year.
I thought Tiller was zero sum budgeting with monthly category rollovers, which is what has worked for me for a long time, so I’m not looking to switch to a new system. After looking at it more this weekend, I realized getting the “planned cashflow” to zero gives me my zero sum budget but the lack of category rollovers is a dealbreaker for me and the Foundation template. I’ll have a go at the older Tiller budget sheet, as I think that (hopefully) has category rollovers!
