About the Military Leave Calculator
When employees are called to military service, USERRA (Uniformed Services Employment and Reemployment Rights Act) protects their civilian employment rights. Many employers voluntarily pay a differential — the gap between the employee's civilian salary and their military pay — to ease the financial burden of service.
This calculator estimates the pay differential between civilian and military compensation, the cost of continuing employee benefits during military leave, and the total employer cost for supporting service members. It helps both employers budget for military leave obligations and employees understand their financial position during service.
Whether you're a reservist planning for annual training or an employer managing a deployment, this estimate adds clarity on the financial aspects of military leave.
When This Page Helps
Military pay structures are complex, making it hard to estimate the income gap. This calculator simplifies the comparison and helps employers plan the cost of differential pay and benefit continuation programs.
How to Use the Inputs
- Enter the employee's regular civilian pay (daily or monthly).
- Enter the expected military pay for the same period.
- Enter the number of leave days or months.
- Enter monthly benefit continuation costs (health insurance, retirement, etc.).
- Review the pay differential and total employer cost.
Formula used
Pay Differential Per Period = Civilian Pay − Military Pay
Total Differential = Differential × Periods
Benefit Cost = Monthly Benefits × Months
Total Employer Cost = Total Differential + Benefit CostExample Calculation
Result: $15,000 pay differential, $19,800 total employer cost
Differential: ($6,000 − $3,500) × 6 = $15,000. Benefits: $800 × 6 = $4,800. Total employer cost: $15,000 + $4,800 = $19,800.
Tips & Best Practices
- USERRA requires employers to maintain health coverage for up to 24 months during military service.
- Differential pay is not required by USERRA but many employers and all federal agencies provide it.
- Military pay includes base pay, housing allowance (BAH), and subsistence allowance (BAS) — include all components.
- Reemployment rights under USERRA depend on the length of service and type of discharge.
- Employees must provide advance notice of military service unless prevented by military necessity.
- State laws may provide additional protections beyond federal USERRA.
Understanding Military Pay Differential
The pay differential is the difference between what an employee earns as a civilian and what they receive in military compensation. Military pay includes base pay (determined by rank and years of service), Basic Allowance for Housing (BAH), and Basic Allowance for Subsistence (BAS). Some service members receive additional special pays.
Employer Obligations Under USERRA
While USERRA does not mandate differential pay, it does require employers to maintain health coverage, treat military absence as non-breaking for benefits purposes, and promptly reemploy returning service members in their prior position (or equivalent). Failure to comply can result in DOL enforcement and private lawsuits.
Best Practices for Supporting Service Members
Leading employers go beyond USERRA minimums by offering full differential pay, continuing all benefits at the employer's cost, providing transition support upon return, and recognizing military service as a development opportunity. These practices improve retention and build a supportive workplace culture.

Frequently Asked Questions
USERRA is the Uniformed Services Employment and Reemployment Rights Act. It protects service members' civilian jobs during military service and guarantees reemployment rights upon return. It applies to virtually all employers regardless of size.
No. USERRA does not require employers to pay any wages during military leave. However, the federal government pays differential pay to its employees, and many private employers have adopted similar policies as a benefit.
USERRA protects cumulative absences of up to 5 years with a single employer, with many exceptions that don't count toward the limit (initial enlistment beyond 5 years, involuntary extensions, training requirements, etc.).
Health coverage must be continued for up to 24 months. For leaves of 30 days or less, the employee pays only the regular employee share. For longer leaves, the employer can charge up to 102% of the full premium (employer + employee share).
No. Under USERRA, military service is not treated as a break in employment for pension vesting, seniority, pay increases, and other length-of-service benefits. The employee is treated as if continuously employed.
USERRA covers active duty, active duty for training, inactive duty training, full-time National Guard duty, and fitness examinations. It applies to all branches of the uniformed services including the Coast Guard and Public Health Service.
