How much can I deposit in the Military Savings Deposit Program (SDP)?

You can deposit up to $10,000 and earn interest at 10% APR. The maximum amount that can earn 10% interest is $10,000 (principal and accrued interest combined).

You cannot close your account until you have left the combat zone, although your money will continue to draw interest for 90 days once you’ve returned home or to your permanent duty station.

The interest you earn on your SDP account is not tax-exempt. More information is available in the Department of Defense Financial Management Regulations.
