Q. I have approximately 200K in my TSP. I would like to leave the principle to my children and take a yearly withdrawal of the interest earned. What, and I know it is an estimation, would you think is a safe percentage to withdrawal yearly?
A. Interest does not accrue in a TSP account. The share values change in response to changes in value. The maximum safe withdrawal rate will depend upon a number of factors including your age, health and how the money is invested and managed over time. Calculating this estimate is beyond the scope of this forum.
