What is a US Navy SRB Calculator?
The Selective Reenlistment Bonus (SRB) is the Navy’s primary tool for retaining Sailors in critical ratings and skill sets. This calculator helps service members determine the financial incentive offered for extending their naval career.
By inputting your current monthly basic pay and the multiplier specific to your rating/zone, you can accurately forecast your lump-sum or installment-based bonus payments to better plan your financial future.
How to Calculate US Navy SRB (Example):
- Identify your Monthly Basic Pay (e.g., an E-5 with 6 years might earn $3,500).
- Find your SRB Multiplier from the latest Navy message (e.g., 2.0).
- Determine your Additional Obligated Service years (e.g., 4 years).
- Multiply them: $3,500 \times 2.0 \times 4 = $28,000.

Frequently Asked Questions (FAQ):

Typically, 50% is paid in a lump sum upon reenlistment, and the remainder is paid in equal annual installments over the rest of the contract.

Zone A (0-6 years), Zone B (6-10 years), and Zone C (10-14 years) represent different career stages for reenlistment eligibility.
Can I get an SRB if I extend instead of reenlisting?
Usually, SRBs require a formal reenlistment contract, though certain long-term extensions may qualify under specific Navy policies.
