Survivor benefit amounts are the same when it comes to disability cases. However, if you are disabled, you can claim your reduced survivor benefits at age fifty, as opposed to age sixty if you are not disabled. The reduced benefit amount at fifty would be 71.5 percent of your deceased spouse’s full retirement benefits. If you waited until reaching full retirement age, your survivor benefit would be equal to 100 percent of your deceased spouse’s full retirement benefits.
If your existing disability benefits are worth more than your survivor benefits, you would not be eligible for survivor benefits. If your survivor benefits are worth more than your disability benefits, your disability benefits would be increased to include survivor benefits.
