Emergency fund first: how much cash is enough?

Three to six months of essential expenses is a common rule, but your job security and dependants may argue for more.

Before investing for the long term, most planners suggest holding a cash buffer so that a car repair or a layoff does not force you to sell at a bad time.

None of this is a forecast, and past performance does not predict future results. Fees, taxes and time horizon matter at least as much as the product itself, and a plan you can stick with through a bad year usually beats a clever one you abandon.
