In most cases, your Social Security income is predictable.
Using a formula that takes into account your entire working career and the age at which you file for benefits, the Social Security Administration calculates what your exact payout will be. You can access this information at any time on the Social Security website at www.ssa.gov.

However, in some cases, you may not receive the full payout that you're expecting. Here are some factors that can cause your Social Security check to be lower than expected.
Medicare Premiums
One of the benefits of retiring is that you may be eligible for Medicare benefits, and a portion of those may be free. As long as you've paid enough qualifying Medicare taxes while you were working, hospital care, which is covered under Medicare Part A, is typically free. However, if you're looking for additional coverage for outpatient and diagnostic services, you'll need to enroll in Medicare Part B. This costs a premium, and it is taken from your Social Security check.

The amount of the Part B premium depends on your income. For singles earning $91,000 or less, or joint filers with income of $182,000 or less, the monthly premium is $170.10. As your income increases, the premium can jump to $238.10, $340.20, $442.30, $544.30, or $578.30 for those earning $500,000 or above ($750,000 for joint filers). In other words, depending on our income, Medicare premiums can put a serious dent in your Social Security check.
Creditor Attachment
If you owe certain unpaid debts, creditors may legally attach your assets. For example, if you can't make your car payments any more, the bank holding your loan might repossess your car.
In other cases, creditors may be able to garnish your wages. While Social Security payments for the most part are protected, certain high-ranking creditors may be able to lay claim to them. Chief among those are the IRS, which can take some of your Social Security check to pay back taxes.
Defaulted student loans, unpaid alimony or child support may also result in reduced Social Security checks. Regardless of the creditor, however, your first $750 of monthly Social Security checks are protected by law.
Early Filing
One of the sure-fire ways to reduce your Social Security check is to claim benefits early.
For those born in 1960 or later, the Social Security Administration defines full retirement age as 67. Although you can claim benefits as early as age 62, they will be permanently reduced, by 30%.
