Hello everyone - I've checked for earlier postings on this subject and have not had a hit. I have a question regarding the TSP web site calculators 'Projecting Your Account Balance' and 'Monthly Payment Calculator', how close to the actual, final balance & monthly payment amounts are they ? I've also done the TSP balance calculator on EBIS (Employee Benefit Information System) which seems a bit more flexible than the TSP site balance projection calculator. My planned retirement date from the State Department is 03/31/2012. Thanks for any info ! - Michael
