One of the first questions every CPA candidate asks is: how long is this going to take? The answer depends on your personal circumstances, but there are well-established benchmarks and patterns that can help you set realistic expectations and build a study timeline that actually works.
This guide covers average timelines, study hour recommendations, the factors that speed up or slow down your progress, and the critical 30-month window that every candidate needs to understand.
The Average Timeline
Most candidates take 12 to 18 months to pass all four sections of the CPA exam. Some candidates finish in as little as 6 to 9 months, while others take the full 30 months allowed or longer if retakes push them past the window.
Here is a breakdown of typical timelines by candidate type:
- Full-time studiers (not working): 4 to 8 months. With 30 to 40 hours per week available for study, dedicated full-time candidates can move through all four sections relatively quickly.
- Working professionals (full-time job): 12 to 18 months. This is the most common scenario. With 15 to 20 hours per week for study, each section takes roughly 6 to 10 weeks of preparation.
- Busy season warriors (public accounting): 15 to 24 months. Candidates in public accounting often need to work around busy season, effectively pausing their studies for several months each year.
- Part-time studiers (limited hours): 18 to 30 months. Candidates with limited study time need to be strategic about pacing to avoid the 30-month window expiration.
Study Hours Per Section
The AICPA and CPA review course providers generally recommend the following study hours per section:
- FAR: 100 to 150 hours. FAR has the most content and consistently requires the most study time.
- AUD: 80 to 100 hours. AUD is conceptually challenging but has a narrower content scope than FAR.
- REG: 80 to 100 hours. REG covers both tax and business law, but many candidates find the material more intuitive.
- Discipline section (BAR, ISC, or TCP): 60 to 90 hours. The discipline sections are more focused, and you are choosing an area that aligns with your strengths.
Total recommended study hours across all four sections: approximately 300 to 400 hours. Some candidates need more, some need less. The key variable is not just hours but the quality of those hours.
Factors That Affect Your Timeline
Several factors can accelerate or extend your CPA exam journey:
Your Academic Background
Candidates who recently completed accounting coursework have a meaningful advantage. The material is fresher, and the study process is more like review than learning from scratch. If you have been out of school for several years, expect to spend more time rebuilding foundational knowledge before you can focus on exam-specific preparation.
Your Work Schedule
This is usually the single biggest factor. A candidate with 25 available study hours per week will progress roughly twice as fast as one with 12 hours per week. Be honest about how much time you realistically have, factoring in work commitments, family obligations, exercise, and the need for rest.
Study Consistency
Consistent daily study of 1 to 2 hours is generally more effective than marathon weekend sessions. Spaced repetition, regular review, and daily engagement with the material lead to better retention than cramming. Candidates who study consistently tend to pass in fewer attempts.
Section Order Strategy
Your choice of section order can affect your overall timeline. Starting with FAR, the largest section, while your motivation and study stamina are at their peak is a common and effective strategy. If you start with a smaller section and then hit FAR in the middle of your journey, the increased study time required for FAR can be demoralizing.
Retakes
Retakes are the biggest timeline disruptor. Each failed section adds weeks of additional study time and the time required to reschedule and retake the exam. Given that approximately half of all exam attempts result in failure, it is wise to build buffer time into your plan for potential retakes.
The 30-Month Window: Understanding the Clock
The 30-month rolling window is one of the most important rules to understand. Here is how it works:
- The clock starts when you pass your
- first
- section
- You must pass the remaining three sections within 30 months of that first passing date
- If 30 months elapse before you pass all four sections, your earliest passed section expires and you must retake it
- The window rolls, meaning if you pass Section 1 in January 2025 and Section 2 in June 2025, Section 1 expires in July 2027 and Section 2 expires in December 2027
Why the 30-Month Window Matters
The window creates urgency. If you spread your sections out too far or encounter setbacks, you risk losing credit for sections you have already passed. This is one of the most frustrating experiences a CPA candidate can have, and it is entirely avoidable with good planning.
Strategic implications of the 30-month window:
- Do not start the exam process until you are genuinely ready to commit to consistent studying for the duration
- If you pass your first section, maintain momentum. Extended breaks between sections increase the risk of the window catching up to you.
- Plan for a total timeline of 12 to 18 months to give yourself ample buffer within the 30-month limit
- If you are approaching the 30-month mark on an early section, prioritize retaking that section before it expires
Building a Realistic Study Schedule
A realistic study schedule accounts for your work commitments, personal life, and energy levels. Here is a framework for building one:
Step 1: Assess Your Available Hours
Be brutally honest. If you work 50 hours per week and have family obligations, claiming you will study 25 hours per week is unrealistic and sets you up for disappointment. Most working professionals can realistically commit to 10 to 20 hours per week.
Step 2: Map Out Your Sections
Based on your available hours, estimate how long each section will take:
- At 15 hours per week, FAR (120 hours) takes about 8 weeks
- At 15 hours per week, AUD (90 hours) takes about 6 weeks
- At 15 hours per week, REG (90 hours) takes about 6 weeks
- At 15 hours per week, your discipline section (75 hours) takes about 5 weeks
Step 3: Add Buffer Time
Build in one to two weeks of buffer between each section for scheduling, score waiting, and mental recovery. Also add buffer for potential retakes. A plan with zero margin is a plan that will break at the first sign of trouble.
Step 4: Account for Life Events
Major life events such as holidays, vacations, busy season at work, weddings, and other commitments will interrupt your study schedule. Plan for them rather than pretending they will not happen.
Sample Timelines
Here are three realistic timeline examples:
Aggressive Timeline (6 to 9 Months)
This works for candidates studying full-time or those with very flexible schedules and strong accounting backgrounds.
- Months 1 to 2: FAR (study and take exam)
- Month 3: AUD (study and take exam)
- Months 4 to 5: REG (study and take exam)
- Month 6: Discipline section (study and take exam)
- Months 7 to 9: Buffer for retakes if needed
Standard Timeline (12 to 15 Months)
This is the most common and achievable timeline for working professionals studying 15 to 20 hours per week.
- Months 1 to 3: FAR
- Months 4 to 5: AUD
- Months 6 to 8: REG
- Months 9 to 10: Discipline section
- Months 11 to 15: Buffer for retakes and score waiting
Extended Timeline (18 to 24 Months)
This works for candidates with limited weekly study hours or those working through busy season schedules.
- Months 1 to 4: FAR
- Months 5 to 8: AUD (with a break during busy season)
- Months 9 to 12: REG
- Months 13 to 16: Discipline section
- Months 17 to 24: Buffer for retakes
Tips for Staying on Track
The biggest challenge is not starting; it is maintaining consistency over months of studying. Here are strategies that successful candidates use:
- Set specific daily study goals rather than vague weekly targets. "Study Chapter 5 and do 30 MCQs tonight" is better than "study FAR this week."
- Track your progress visually. Whether it is a spreadsheet, a wall calendar, or an app, seeing your progress builds momentum.
- Schedule your exam date early to create a deadline. Having a fixed exam date prevents indefinite procrastination.
- Find accountability through a study partner, online community, or mentor who checks in on your progress.
- Celebrate milestones when you pass a section. The CPA journey is long, and acknowledging progress helps sustain motivation.
- Do not aim for perfection in your study. You need a 75, not a 99. Focus on understanding the most heavily tested topics rather than mastering every obscure detail.
When Should You Start?
The best time to start studying for the CPA exam is when you have the prerequisites met and can commit to a consistent study schedule for the foreseeable future. Delaying rarely makes things easier. The longer you wait after finishing your accounting coursework, the more material you will need to relearn.
If you are waiting for the "perfect time," it may never come. Life always has competing demands. The candidates who pass are the ones who start despite imperfect circumstances and maintain discipline over time.
