Reenlistment Bonus Calculator
Selecting a grade auto-fills monthly basic pay from the 2026 pay table.
Used to determine your reenlistment zone (A: 1.4–6 yr, B: 6–10 yr, C: 10–14 yr) and look up your pay.
Auto-filled from the 2026 pay table. Override if your actual pay differs.
Check your current SRB message or retention NCO. Typical range: 1–10. Statutory maximum: 15.
Minimum 3 years for SRB eligibility. Longer contracts increase total bonus but also increase obligation.
Reenlisting in a designated CZTE area makes the entire bonus (lump sum + all installments) exempt from federal income tax.
Enter any SRB amounts received in prior zones. Career cap is $360,000 total.

How to Use This Calculator
Select Your Branch, Grade, and Years of Service
Choose your military branch and pay grade from the dropdowns. Enter your total years of active duty service — the calculator will auto-fill your 2026 monthly basic pay from the official DFAS pay table and automatically identify your reenlistment zone (A, B, or C).
Enter Your SRB Multiplier and Contract Length
Obtain your MOS, rating, or AFSC's current SRB multiplier from your retention NCO or the official quarterly SRB message for your branch. Use the slider to set the multiplier (0.5–15). Then select your planned contract length (3–8 years). Longer contracts yield higher totals but greater commitment.
Configure Tax Settings
If you are reenlisting in a designated Combat Zone Tax Exclusion (CZTE) area, toggle 'Yes — Tax Exempt' to remove all federal and state tax withholding from your results. Otherwise, the default 22% federal IRS supplemental rate applies. Adjust the state tax rate to match your state of legal residence — enter 0 for states with no income tax or those that exempt military pay.
Review Results and Export
Instantly see your gross SRB, net take-home, initial lump sum, and annual installment amounts. The career cap tracker shows how much of your $360,000 lifetime SRB cap you have used. Use 'Export CSV' to download the full year-by-year payout schedule for your records or to share with a financial advisor.
Frequently Asked Questions
How is the Selective Reenlistment Bonus calculated?
The standard DoD formula is: Total SRB = Monthly Basic Pay × SRB Multiplier × Years of Additional Obligated Service. For example, an E-5 earning $3,959 per month reenlisting for 4 years at a multiplier of 3 would earn a gross SRB of $47,508. The result is capped at $30,000 per contract year (so $120,000 for a 4-year contract) and is also subject to the $360,000 career cap. Payment is 50% as a lump sum at reenlistment and 50% in equal annual installments paid on each reenlistment anniversary.
What are Zones A, B, and C?
SRB reenlistment zones are defined by total active duty time in service. Zone A covers members with 17 months through 6 years of service — typically a service member's first reenlistment opportunity. Zone B covers 6 through 10 years, capturing experienced mid-career NCOs. Zone C covers 10 through 14 years, targeting senior specialists. Members outside these windows are not eligible for SRB under the standard DoD program. A service member can potentially earn SRB in each zone once, up to the $360,000 career cap.
Is the reenlistment bonus taxable?
Yes, SRB payments are generally subject to federal income tax, withheld at the IRS supplemental wage flat rate of 22%. State tax withholding depends on your state of legal residence — some states like Texas, Florida, and Washington have no state income tax, while others exempt military pay entirely. An important exception: if you reenlist while serving in a designated Combat Zone Tax Exclusion (CZTE) area, the entire SRB — including all future annual installments — is fully exempt from federal income tax. This exemption is one of the most valuable aspects of combat zone reenlistments.
How does the 50/50 payment split work?
Federal law requires that at least 50% of the total SRB be paid as a lump sum within 30 days of reenlistment. The remaining 50% is divided into equal installments paid on each anniversary of the reenlistment date over the length of the contract. For a 4-year reenlistment earning $48,000 gross, the service member receives $24,000 at reenlistment and four annual installments of $6,000 each year. Tax is withheld proportionally from both the lump sum and each installment unless the reenlistment qualifies for combat zone tax exemption.
What is the career cap for SRB, and does it reset?
The statutory career cap for SRB is $360,000 in total gross bonus payments across an entire military career. This cap does not reset — it is a lifetime limit on all SRB amounts received in any zone, any branch, and any contract. If a service member has already received $180,000 in prior SRBs, the maximum remaining SRB for future reenlistments is $180,000, regardless of what the formula would otherwise produce. This calculator's career cap tracker lets you input previous SRB amounts to see your remaining lifetime limit before committing to a new contract.
What happens to my installments if I separate before the contract ends?
If you voluntarily separate or are involuntarily discharged before completing your reenlistment contract, you may be required to repay a prorated portion of the SRB — specifically the unearned installments that have not yet been paid. Each annual installment is considered 'earned' on the anniversary date it was due. If you are separated due to service-connected disability or other involuntary reasons, recoupment may be waived at the discretion of the service secretary. Always consult your JAG officer or military legal advisor if facing early separation to understand your specific repayment obligations.
