Frequently Asked Questions
A TSP annuity is a monthly payment for life purchased with your Thrift Savings Plan balance upon retirement. The amount depends on your age, gender, and annuity type.
The calculator uses approximate TSP annuity purchase rates by age and gender. It multiplies your balance by the rate to get an annual payment, then divides by 12.
No, these are estimates. Actual TSP annuity rates vary and are set by the TSP at the time of purchase. Consult official TSP resources for precise figures.
