The Helm's need to increase their liquid assets until they have reached the minimum of three full months of their total income. This information indicates that the Helm's need to save an additional seven thousand dollars before their safety cushion is adequate. The first thing that the Helm's need to do is to create a working budget in order that they can determine an appropriate amount of their money that can be safely withheld each month to increase their liquid funds.
It would be a wise investment for the Helm's to transfer their 600 dollars into a wonderful NOW account. The now account pays 3 percent interest if more than the minimum balance of 2500 dollars is maintained. If their balance drops below this, they will only earn 2 percent interest on their money. Regardless, they would still be earning a small amount of interest. To make it ideal they should only deposit enough into this account to pay their monthly, personal bills and enough money for miscellaneous items such as groceries, etc.
The Helm's should keep 1,000 in their regular savings to accomodate emergencies, such as new tires, for their vehicle, family emergencies, etc. This will keep cash on hand while paying them 3.5% interest on the money in the account.
The Helm's should take 5,000 of their savings and purchase several CD's with this. Though they could purchase one large CD it is in their best interest to purchase about three in different denominations and at different maturity points for the rollover. This way their money would be gaining 6% interest and though it would be frozen so to speak, it would be available at different times also.
The Helm's should place their remaining remaining 1400 dollars into stocks. Of importance is that their portfolio is diversified. They should divide it among utilities, oil and electricity to begin with as these are demand and needed items. As their monies grow they can diversify more. When they have purchased a stock that is lagging the loss will be minimal as the gain and dividends in the demanded commodities will offset the loss of these.
