CPA Exam Study Planner

Plan your study timeline across all 4 CPA exam sections within the credit window.

About this calculator

The Uniform CPA Examination under the "CPA Evolution" model has three Core sections everyone takes -- AUD (Auditing and Attestation), FAR (Financial Accounting and Reporting), and REG (Regulation) -- plus one Discipline section chosen from TCP (Tax Compliance and Planning), BAR (Business Analysis and Reporting), or ISC (Information Systems and Controls). This planner assumes TCP as the discipline choice since it's the most common pairing for candidates heading toward general tax or public accounting practice, but the study-hour math works the same way if you substitute BAR or ISC hours for TCP. Once you pass your first section, the clock starts on a "credit window" -- a rolling deadline to pass the remaining three before your earliest passing score expires.

That window used to be a fixed 18 months everywhere, but NASBA's 2023 model rule amendment extended it to 30 months, and nearly all state boards have since adopted the longer window -- though a few may not have yet, so it's worth confirming your specific state's rule before treating 30 months as guaranteed. Buffer Weeks / Section pads each section's raw study-hours-divided-by-weekly-hours estimate to account for review time, exam scheduling lead time, and life simply not going exactly to plan -- skipping it tends to produce an optimistic timeline that real study schedules rarely hit.

How to Use This Calculator
  1. Enter Study Hours / Week — the number of hours you can realistically commit to CPA study each week.
  2. Enter the recommended study hours for each section: AUD, FAR, REG, and TCP. Most review courses suggest 100–150 hours per section.
  3. Set Buffer Weeks / Section (1–2 weeks) to account for review, scheduling delays, and exam day logistics.
  4. If you have already passed some sections, update Sections Already Passed so the planner skips those.
  5. Review Total Months and Within 30-Month Window? — nearly all state boards now allow 30 months from your first passing score to finish all four sections (confirm your own state's rule, since a few boards may still run 18 months).
  6. Use the Study Plan by Section table to assign target exam dates for each section.

Frequently Asked Questions

Is the CPA exam credit window 18 months or 30 months?

It depends on your state board, but as of NASBA's 2023 model rule amendment, nearly all US jurisdictions have moved to a 30-month rolling window from your first passing score. A handful of state boards may not have formally adopted the change yet, so confirm your specific board's current rule rather than assuming -- this planner uses 30 months as the now-typical default.

Why does this planner assume TCP instead of BAR or ISC as my Discipline section?

TCP (Tax Compliance and Planning) is the most common Discipline choice for candidates pursuing general public accounting or tax-focused careers, so it's used as the default fourth section. If you're taking BAR or ISC instead, just enter that section's recommended study hours in the TCP Study Hours field -- the study-time math treats all three Discipline options identically.

How are the recommended study hours per section determined?

The default hour ranges (100-150 hours per section) reflect commonly cited review- course guidance, but actual hours needed vary significantly by your accounting background, how recently you studied the material, and which review provider you're using. Adjust each section's hours to match your own review course's recommendation or your personal pace from practice exams.

Why does Sections Already Passed change which study-hour fields get counted?

Because the planner assumes you pass sections in AUD, FAR, REG, TCP order for planning purposes and skips the study time for sections you've already cleared. If you passed sections out of that order, the remaining-hours total will still be accurate as long as the number of sections passed is correct, even though the specific section names skipped may not match your actual history.

What happens if my Total Weeks exceeds the credit window?

Within 30-Month Window? switches to "At Risk," meaning your current study pace and buffer assumptions put you on track to exceed the rolling window before finishing all four sections -- at which point your earliest passing score could expire, forcing you to retake that section. Increasing Study Hours / Week or reducing Buffer Weeks / Section (if realistic) are the two levers this planner exposes to pull the timeline back inside the window.
