Why you need emergency funds
How much do you need?
Where should you keep these funds?
Avoid using costly credit cards when emergencies arise
Reduce your insurance costs
If you have a fund to pay for insurance deductibles you can save on insurance premiums
Peace of mind
Three months worth of expenses if you're in a fairly normal situation
Six months worth of expenses if you're in an unstable situation (seasonal business, possible layoff)
Money market mutual fund or short-term bond fund
Short-term bond fund
Will pay a little more in interest
But realize that the short-term bond fund is subject to slight fluctuations in share price and you'll have a taxable capital gain transaction each time you sell shares
