What you earn and what it costs to get there.
Median
$93,790
Bottom tenth
$55,390
Top tenth
$160,540
The national median is $93,790 a year, and the bottom tenth start near $55,390. The survey counts every detective and criminal investigator together, from small town detectives to federal agents. Federal agents sit in the upper half of that spread, because federal pay adds a locality adjustment for your city and a premium for being on call.
Upper $50,000s to low $80,000s
New federal agents, depending on the city you are posted to
Federal law enforcement pay is set by grade and step, then raised by a locality percentage for where you work. New York and San Francisco postings pay noticeably more than rural ones for the same job.
About 25% extra
Availability pay for federal criminal investigators
Federal criminal investigators are required to be available for unscheduled duty, and federal pay rules add a premium on top of base salary for it. It is a large part of why agent pay outruns the base tables.
Tuition, fees, exams and kit. Not rent, food or travel
The academy itself costs nothing, because you are a paid employee during training and housing is provided, so the whole expense is the bachelor's degree you need before applying. The low end is two years at a community college then transferring to finish at an in state public university. The high end is four years paying out of state public rates. The hiring process is free but can run a year or more of testing and waiting, and federal service counts toward Public Service Loan Forgiveness, which can clear remaining federal student loans after 10 years of qualifying payments.
File the FAFSA (Free Application for Federal Student Aid) for the degree part. Federal service also counts toward Public Service Loan Forgiveness, which can wipe remaining federal student loans after 10 years of qualifying payments.
A federal law enforcement pension
Agents can retire earlier than ordinary federal staff, and must retire at 57. Twenty years of service and age 50 is the common exit point.
Federal health insurance and a retirement savings plan
The government contributes to the Thrift Savings Plan on top of your own contributions.
Public Service Loan Forgiveness
Federal employment is qualifying work for the program that cancels remaining federal student loans after 10 years of payments.
Training you cannot buy
Interviewing, forensics, firearms, surveillance and specialist courses, all paid for while you are on salary.
The exact path from high school to qualified.
There is no license and no single exam. There is a hiring standard, and it is strict.
High school
Grade 12
Grades matter for university admission. A clean record matters more, because a background investigation will look at all of it.
Bachelor's degree
4 years
Any subject. Accounting, computer science, languages and law are the backgrounds the Bureau openly wants most.
Work full time in the real world
1 to 2 years
You need at least two years of full-time professional experience, or one year with an advanced degree. This is not optional and it is why almost nobody is hired at 22.
Apply and get through the process
9 to 18 months
Written testing, interviews, a physical fitness test, a full background investigation, a polygraph and a medical exam. Expect it to take many months.
The academy at Quantico, Virginia
About 5 months
Months of residential training in law, investigations, firearms, defensive tactics and physical conditioning, then a first field office assignment.
Accounting or business
A very large share of federal cases are financial. Agents who can read a set of books are in demand.
Computer science
Cyber intrusion is one of the Bureau's biggest workloads and one of its hardest hiring gaps.
A foreign language
Arabic, Mandarin, Russian and Spanish speakers are actively recruited.
English
Investigative reports get read by lawyers and juries. Sloppy writing loses cases.
Nobody issues you a certificate that makes you a federal agent. You are one because the Federal Bureau of Investigation (FBI) hired you and can un-hire you. The published requirements are citizenship of the United States, a bachelor's degree, at least two years of full-time professional work experience or one year with an advanced degree, a valid driver's license, passing the physical fitness test, meeting the medical standard, and being legally able to carry a firearm. You must be at least 23 and apply before turning 38, with exceptions for veterans and people with prior federal law enforcement service. Every opening is posted on USAJOBS (the federal government's official jobs site).
There is no preferred school. There are preferred skills.
Accounting
Fraud, public corruption and organized crime cases run on financial records. This is the single most requested background.
Computer science or cybersecurity
The Bureau competes with private tech salaries for these people and rarely has enough of them.
Criminal justice
Common, and useful for understanding the system, but on its own it makes you look like every other applicant. Pair it with something technical.
John Jay College of Criminal Justice, New York
A public college in the City University of New York system built entirely around justice careers, from forensic science to public administration.
Things you don't need, but that help.
Certified public accountant
An accounting license plus investigative interest is close to a golden ticket for financial crime work.
Military or police service
Counts as professional experience, and veterans get an exception to the upper age limit.
A law degree
Useful for complex white-collar and public corruption cases, and a route into legal roles at the Bureau.
Fluency in a hard language
Tested formally, and it can attach you to work nobody else can do.
A pilot certificate
Federal agencies run their own aircraft and hire agents who can fly them.
Recent drug use
There is a published policy with time limits on past use. Read it before you apply, not after.
A messy financial history
Serious unpaid debt is treated as a security risk during the background investigation.
Failing the fitness test
Timed runs, sit-ups, push-ups and a sprint. People train for months for it and still fail.
Lying on the application
The polygraph and background check are built to find it, and it ends the process immediately.
The Federal Bureau of Investigation (FBI) is one of many federal agencies that hire criminal investigators. The Drug Enforcement Administration, the Secret Service, Homeland Security Investigations, the Bureau of Alcohol, Tobacco, Firearms and Explosives and the criminal investigation arm of the Internal Revenue Service all hire agents on similar federal pay and similar rules. They post on the same site, they have similar age limits, and the application timelines are just as long. Many people apply to several at once.
Day to day, pros and cons, where you'd work.
Far more desk than television suggests. Mornings are case files, subpoenas, writing up interviews and coordinating with prosecutors. Afternoons might be an interview across town, a meeting with a source, or sitting in a car for four hours watching a door. Court testimony eats whole days. A few times a year it is an arrest at dawn or a search warrant, and those days are the ones people remember. The paperwork after them is the part nobody films.
The good
The hard parts
Things people don't tell you.
You must be at least 23 to become a special agent and you have to apply before your 38th birthday, unless you are a veteran or already have federal law enforcement service. It is one of the few careers with a hard upper age limit written into the rules.
Applicants sign up for mobility. Your first office could be anywhere in the country, and later assignments can move you again. People with roots in one town find this the hardest part of the job, not the danger.
Federal law enforcement officers face mandatory retirement, and in exchange they can draw a pension far earlier than other federal workers. Plenty of former agents start a second career in their fifties.
Fraud, corruption and organized crime cases are won by following money through records. An accounting background is one of the most requested qualifications in federal investigative hiring.
Last checked September 2026. Pay figures are typical full-time annual amounts in United States dollars, based on Bureau of Labor Statistics wage data and published pay scales. They vary by state, employer and experience. Tuition is for in-state students at public schools unless the card says otherwise.
