It should happen just like the video said. Per TSP website: If you’re a FERS or eligible BRS participant, you receive Agency/Service Matching Contributions on the first 5% of pay you contribute every pay period. The first 3% is matched dollar-for-dollar by your agency or service; the next 2% is matched at 50 cents on the dollar. This means that when you contribute 5% of your basic pay, your agency or service contributes an amount equal to 4% of your basic pay to your TSP account. Together with the Agency/Service Automatic (1%) Contribution given to you, your agency/service puts in a total of 5%.
