Calcium and Dairy. Foods classified by the USDA as dairy products supply calcium to the diet. Calcium is stored in your bones, which makes them dense. Too little calcium in your diet can increase your risk of developing low bone density and fractures.
For example, say that your traditional IRA has a cost basis of $30,000 and is worth $100,000 when you take a $10,000 withdrawal. That means 30 percent of the withdrawal comes out of your cost basis and is tax-free; 70 percent comes from the remainder of the account and is taxable.
Divide the IRA basis by the balance in your traditional IRA account to find the percentage of the balance that is your IRA basis. For example, if you have a balance of $75,000 and an IRA basis of $15,000, divide $15,000 by $75,000, which works out to 20 percent.tep 4. Multiply the amount of the traditional IRA distribution by the percentage of IRA basis. If the basis percentage is 20 percent and you take out $10,000, you would multiply $10,000 by 20 percent, which equals $2,000.
