It fully depends what are you going to do and how much are you spending. To get a baseline of what you need, calculate your living expensed plus do the worst-case calculations for a year. Expect that your currently fully-working laptop and mobile phone are both going to break and you have to buy new ones. (sudden hw costs can be easily a couple of grands). Ditto for cars etc. If you have a spouse, don't expect that working from home for a year is such a great idea, thus plan some money for renting a space.
