Firefighter Pay, Overtime & Pension Glossary

Firefighter compensation is negotiated piece by piece. Base salary, scheduled hours, overtime thresholds, specialty stipends, and pension formulas each appear as separate clauses in a collective bargaining agreement (CBA) — and a single misread term can swing a career decision by tens of thousands of dollars.

This glossary defines the terms that matter most when comparing departments, from the FLSA Section 7(k) work period that governs overtime to the final average salary that determines a pension. Each entry explains what the term means and how it changes take-home pay or retirement income, so you can read any pay scale or contract with confidence.

Use it alongside the city comparison tool, the department directory, and the shift calculators to interpret the numbers behind a municipal pay scale. Every figure referenced in these definitions is an educational example — always confirm the exact language in your own CBA and with the relevant state pension system before making a career decision.

Overtime & Scheduling

FLSA Section 7(k)
A provision of the Fair Labor Standards Act that lets public fire departments use a work period of 7 to 28 days instead of the standard 7-day workweek. Under 7(k), firefighters earn overtime only after exceeding the statutory hours cap for the chosen period — 212 hours in a 28-day period.Related: Work Period, Regular Rate, Kelly Day
Kelly Day
A scheduled paid day off inserted into a firefighter's shift rotation to reduce total hours within the FLSA work period. Kelly Days lower overtime liability by keeping annual and per-period hours closer to the statutory threshold.Related: Work Period, FLSA Section 7(k)
Work Period
The recurring number of consecutive days a fire department designates for measuring overtime under FLSA 7(k), ranging from 7 to 28 days. The period length sets the department's straight-time hour cap, from 53 hours at 7 days up to 212 hours at 28 days.Related: FLSA Section 7(k), Kelly Day

Pay & Stipends

Cost-of-Living Index
A regional measure that compares local prices with the national average, set at 100. A high index means a salary buys less locally, so comparing nominal pay across cities without adjusting for cost of living can be misleading.Related: COLA (Cost-of-Living Adjustment)
Hazard Pay
Additional compensation for assuming above-baseline risk, such as fire suppression, hazardous-materials response, or technical rescue duties. Hazard pay often takes the form of a fixed annual stipend that is included in the regular rate for overtime.Related: Regular Rate, Paramedic Stipend
Longevity Pay
Incremental base-pay increases earned at defined years-of-service milestones, commonly every five years. Longevity increments are frequently pensionable, which means they raise both current pay and the final average salary used for retirement.Related: Final Average Salary (FAS), Shift Differential
Paramedic Stipend
An annual payment to firefighters who hold and maintain paramedic certification. Because it is non-discretionary, a paramedic stipend usually must be included in the regular rate when calculating FLSA overtime.Related: Regular Rate, Hazard Pay
Regular Rate
The hourly pay rate on which overtime is calculated, derived by dividing base annual salary plus most non-discretionary stipends by scheduled annual hours. FLSA overtime is paid at 1.5 times the regular rate.Related: FLSA Section 7(k), Paramedic Stipend, Hazard Pay
Shift Differential
Extra pay added for working evening, night, weekend, or holiday hours, or for long tours such as 48-hour shifts. Shift differentials vary widely by collective bargaining agreement and may or may not be pensionable.Related: Hazard Pay, Longevity Pay

Pension & Retirement

COLA (Cost-of-Living Adjustment)
A periodic increase applied to a retiree's pension to offset inflation, typically expressed as an annual percentage. Some systems grant a fixed 2% COLA, while others use a consumer price index formula or suspend COLAs in weak funding years.Related: Pension Multiplier, Cost-of-Living Index
Deferred Compensation
A voluntary retirement savings plan, such as a 457(b), that lets a firefighter set aside pre-tax income. Deferred compensation supplements a defined-benefit pension and is not guaranteed or funded by the employer's pension system.Related: Pension Multiplier, Vesting
Final Average Salary (FAS)
The average of a firefighter's highest-earning consecutive years of service, used as the base for calculating retirement benefits. Longevity pay, stipends, and overtime may count toward FAS depending on the pension system's rules.Related: Pension Multiplier, Longevity Pay
Pension Multiplier
The percentage applied to final average salary for each year of service to compute the annual pension benefit. A 2.5% multiplier over 25 years of service yields a pension equal to 62.5% of final average salary.Related: Final Average Salary (FAS)
Vesting
The years of service required before a firefighter earns an irrevocable right to a pension benefit. Vesting periods typically range from 5 to 10 years and determine whether a departing firefighter keeps any retirement credit.Related: Pension Multiplier, Deferred Compensation
