Save your loose change. Putting aside fifty cents a day over the course of a year will allow you to save nearly 40% of a $500 emergency fund.
Keep track of your spending. At least once a month, use credit card, checking, and other records to review what you've purchased. Then, ask yourself if it makes sense to reallocate some of this spending to an emergency savings account.
Never purchase expensive items on impulse. Think over each expensive purchase for at least 24 hours. Acting on this principle will mean you have far fewer regrets about impulse purchases, and far more money for emergency savings.
Pay with a debit card rather than a credit card. You cannot use a debit card (unless it has an overdraft feature) to spend money you do not have. Using a debit card may also prevent you from annually incurring hundreds of dollars in credit card interest charges. Both would mean more money available for emergency savings.
