Most CPA candidates need between 300 and 400 total hours of study time to pass all four sections of the exam. That breaks down to roughly 80 to 150 hours per section, depending on the subject and your background. The wide range exists because your accounting experience, how long ago you finished school, and which discipline section you choose all affect how much preparation you actually need.
Study Hours by Exam Section
The CPA exam has three core sections that every candidate must pass, plus one discipline section you choose based on your career focus. Each section demands a different level of preparation.
Financial Accounting and Reporting (FAR) is consistently the most time-intensive section, with a recommended 120 to 150 hours of study. FAR covers the broadest range of material: financial statements, government accounting, nonprofit accounting, and a heavy dose of technical standards. Candidates who have been out of school for a few years often land at the higher end of that range because the content fades quickly without regular use.
Auditing and Attestation (AUD) typically requires 110 to 140 hours. The material is conceptually dense, covering audit procedures, internal controls, professional responsibilities, and reporting requirements. If you work in audit, the concepts will feel more intuitive and you may need fewer hours. If your career is in tax or industry, budget toward the higher end.
Taxation and Regulation (REG) is the lightest of the three core sections at 80 to 110 hours. It covers individual and business taxation, business law, and ethics. Tax professionals often find this section the most manageable, while candidates without tax experience should plan for the full 110 hours or more.
The fourth section is your discipline choice: Business Analysis and Reporting (BAR), Information Systems and Controls (ISC), or Tax Compliance and Planning (TCP). Study hour estimates for these newer sections are still developing, but most prep providers suggest budgeting 80 to 120 hours depending on how closely the material aligns with your work experience.
What Determines Your Personal Total
The 300 to 400 hour range is a useful starting point, but several factors push you toward one end or the other.
Your proximity to coursework matters more than almost anything else. Candidates who sit for the exam within a year of finishing their accounting degree retain enough foundational knowledge to study more efficiently. If three or more years have passed, expect to spend extra time relearning basics before you can tackle exam-level material.
Work experience in a relevant area can shave significant time off a particular section. An auditor who reviews internal controls daily won’t need as many hours on AUD as someone in a corporate finance role. Likewise, a tax associate will move through REG faster than a candidate whose job never touches a tax return.
Your study method also plays a role. Active study, where you work through practice questions, simulate exam conditions, and review incorrect answers in detail, is far more efficient than passively rewatching video lectures. Candidates who spend most of their study time on practice problems and simulations often pass with fewer total hours than those who emphasize reading and note-taking.
How to Spread Those Hours Across a Schedule
Most candidates study for one section at a time, dedicating six to eight weeks per section. That translates to roughly 15 to 20 hours of study per week if you’re working full time. Some candidates compress that timeline to four or five weeks by studying 25 or more hours per week, but burnout becomes a real risk at that pace, especially across multiple sections.
A common approach is to front-load the hardest section. Many candidates start with FAR because it covers the widest range of topics and its content overlaps with other sections. Passing the most demanding section first also builds confidence and momentum. Others prefer to start with the section closest to their daily work so they can build an early win.
Keep in mind that you must pass all four sections within a rolling 30-month window. Once you pass your first section, the clock starts. That timeline is generous enough to allow breaks between sections, but not so generous that you can afford months of downtime. Most successful candidates complete all four sections within 12 to 18 months.
When You Might Need More Than 400 Hours
Some candidates find that the standard estimates fall short. If you’re studying for a section that has little connection to your work or academic background, adding 20 to 30 hours beyond the recommended range is reasonable. The same applies if you’re balancing a demanding job during busy season, caring for family, or studying in a second language. Fatigue and distraction reduce the quality of each study hour, so you may need more of them to reach the same level of readiness.
Retaking a failed section also adds to the total. The cumulative pass rate for first-time attempts hovers around 50% for most sections, so retakes are common and nothing to be ashamed of. If you do need to resit, you likely won’t need to redo all 100-plus hours. Focus your restudy on the weakest content areas, which typically takes 30 to 50 additional hours.
Making Your Study Hours Count
Raw hours matter less than how you use them. Candidates who consistently score well on practice exams before test day tend to pass regardless of whether they studied for 90 hours or 140. A few strategies help maximize the return on every hour you invest.
Prioritize practice questions over passive review. After learning a topic through a lecture or textbook, shift to questions as quickly as possible. Working through hundreds of multiple-choice questions and task-based simulations builds the pattern recognition you need on exam day. Most prep courses include thousands of practice questions, and candidates who complete 80% or more of the available question bank tend to feel significantly more prepared.
Space your review sessions rather than cramming. Revisiting material two or three days after your initial study session strengthens retention far more than reviewing it the same night. This is especially important for FAR and AUD, where the sheer volume of topics makes it easy to forget earlier material by the time you reach the end of the course.
Simulate real exam conditions at least two or three times before your test date. Sit for a full-length practice exam in one sitting, timed, with no phone and no notes. This builds endurance for the four-hour test window and reveals weak spots you might not catch during shorter study sessions.
