How much certainty do you need in your life? Are you a "live for today" sort of person, willing to spend now even if it could result in a shortfall in your income later in life? Or are you someone who would rather spend less during retirement if it means a greater degree of certainty that your money won't run out?
The answer to this question will determine the percentage that you mark in the Certainty of Income column on the Retirement Income Worksheet. If you'd like a high degree of certainty that your money will last throughout your retirement years, circle 85% or 95%. If you're willing to tolerate the possibility of a shortfall in exchange for more spending power early in your retirement years, circle 50%.
