Toggles switch a month on or off in place. Financing redistributes the full annual obligation
across whatever months stay on. Felix 20% and Bill & JP 10% are shown merged as a 30% profit allocation —
it reduces trading capital but carries no withdrawal fee (the annual summary splits the two out).
Only financing, expenses and the balloon are real withdrawals grossed up at 1.5%. Month 12's
all fees also carries the extra 1.5% fee on the whole closing balance. Click an expense name to rename it,
