help me budget a trip to Lisbon
Let me pull your cash + monthly income to size the trip against your savings rate.
how many days can I afford?
A 5–7 day trip fits — budget $1,200–$1,500 total (flights + stay + activities). Pulls from cash, not your emergency fund. Won't move your savings rate more than 0.3 months.
