How Long Does It Take to Become a CPA?

By The Ledgerism Editorial Team · The Ledgerism Brief Editorial Team produces original, methodology-disclosed accounting and tax research—data trackers, databases, and reference guides built to be the most-cited source in the field. Every figure is verified against primary sources including FASB, the IRS, the PCAOB, NASBA, the AICPA, and state boards of accountancy.

For most people, how long it takes to become a CPA is 5 to 7 years from the first day of college to the license in hand. That splits into roughly 5 years of education to reach 150 credit hours, 12 to 18 months to pass all four exam sections, and 1 to 2 years of supervised work experience. The stages overlap, so the real number depends on how much you compress them.

The single biggest driver is the 150-hour education rule. A standard bachelor’s degree is 120 semester hours, and the extra 30 hours are what push a 4-year degree toward a 5-year timeline. The exam and experience requirements can run at the same time as school or each other, which is where the fastest candidates save years.

How long to become a CPA: the timeline at a glance

The traditional CPA path runs about 6 years end to end, and a compressed path can finish in roughly 4. Education is the longest and least flexible stage. The exam and experience stages are where candidates who plan ahead pull months out of the total. The table below shows the typical range for each stage and the lever that shortens it.

Times vary by state. Some jurisdictions require 2 years of experience, and a growing number now offer a 120-hour pathway that trades the extra education for more experience. Confirm the rule with your state board before you plan.

Step 1: Education, the part that sets the clock (about 5 years)

Education is the stage that usually decides how long it takes to become a CPA. Nearly every jurisdiction requires 150 semester hours to be licensed, which is 30 hours beyond a standard 120-hour bachelor’s degree. Most candidates cover that gap with a master’s degree or extra undergraduate credits, adding roughly a year to a 4-year degree.

The 150 hours must include a set number of accounting and business courses, commonly around 24 to 30 accounting hours and 24 business hours, though the exact split is set by each state board. A degree in accounting is not strictly required in every state as long as the coursework thresholds are met.

Note that many states let you sit for the exam at 120 hours (or once a degree is conferred) and only require the full 150 for the license itself. That distinction matters for timing, because it lets you start the exam while you finish the remaining coursework.

Step 2: The CPA Exam and the credit window (12 to 18 months)

Passing the CPA Exam typically takes 12 to 18 months across four sections, and the clock that governs it is the credit window. Once you pass your first section, you have a fixed period to pass the remaining three before that first credit expires. Historically this window was 18 months. As of 2026, most jurisdictions have extended it to 30 months.

The exam uses the CPA Evolution model in effect since January 2024: three required Core sections (Auditing, Financial Accounting and Reporting, and Taxation and Regulation) plus one Discipline section you choose (BAR, ISC, or TCP). Testing is continuous year-round, so you can schedule sections back to back rather than waiting for quarterly windows.

The 30-month window gives real breathing room, but it is not a reason to slow down. A stalled section can still cost you an earlier passed credit if you drift past the deadline. Most successful candidates target one section every 2 to 4 months and finish inside a year.

The 18-month vs 30-month window, explained

The credit window is the number of months you have to pass all four sections after your first passing score, and it recently grew from 18 months to 30 in most states. Under the old 18-month rule, a passed section expired if you had not cleared the other three within 18 months, forcing costly retakes. The 30-month window, recommended by AICPA and NASBA and adopted by a majority of boards in 2025 and 2026, cuts that risk. Adoption is state by state, so verify your jurisdiction on nasba.org before relying on the longer window.

Step 3: Work experience (usually 1 year)

Most states require 1 year of supervised experience, often defined as around 1,600 to 2,000 hours, verified by a licensed CPA. Some jurisdictions require 2 years. The work generally must involve accounting, attest, tax, or advisory services, and it can be earned in public accounting, industry, government, or academia depending on the state.

This stage often does not add to the total timeline, because it can run alongside the exam. Many candidates start a staff role after graduation, study for and pass sections in their first year or two of work, and satisfy the experience requirement at the same time.

How long to become a CPA if you accelerate

A determined candidate can become a CPA in about 4 years by overlapping the stages instead of running them in sequence. The compression comes from three moves: reach 150 hours faster, start the exam before you finish school, and let the work-experience clock run while you test. Done together, they can pull 1 to 2 years out of the traditional path.

Common accelerators:

1. Integrated 5-year degree: A combined bachelor’s-plus-master’s program hits 150 hours in 5 years with a graduate credential attached.
2. Early credit: AP, IB, CLEP, and dual-enrollment credits can shave a semester or more off the undergraduate portion.
3. Community-college hours: Filling the extra 30 hours with lower-cost credits can be faster and cheaper than a full master’s.
4. Sit at 120 hours: In states that allow it, begin testing after your degree while completing the last coursework.
5. Study senior year: Starting review before graduation lets you clear one or two sections before your first full-time job.
6. Alternative 120-hour pathways: Several states now license candidates with a 120-hour bachelor’s plus 2 years of experience instead of 150 hours.

That last point reflects a broader change. Facing a shrinking pipeline of new accountants, states including Texas and Ohio have added pathways in 2026 that trade the 30 extra education hours for an additional year of experience.

What can stretch the timeline

Several factors push the total past 7 years. Failing and retaking exam sections is the most common, since each retake adds a testing window and study cycle. Changing states mid-process can reset education or experience requirements. Part-time study, career changes into accounting, and gaps between passing the exam and finding qualifying work all extend the clock.

State rules are the wild card throughout. Experience length, the accounting-hour breakdown, whether you can sit at 120 hours, and whether the 30-month window applies all vary by jurisdiction. Plan against your own state board’s rules, not a national average, and confirm anything time-sensitive directly with the board.

Frequently asked questions

How long does it take to become a CPA after a bachelor’s degree?

Usually 2 to 3 years after a 120-hour bachelor’s degree. You need roughly 30 more credit hours to reach 150, 12 to 18 months to pass the four exam sections, and 1 to 2 years of supervised experience. Because the exam and experience can overlap with earning the extra credits, the post-degree stretch is often shorter than the parts added together.

Can you become a CPA in less than 5 years?

Yes, in some cases. Candidates who enter college with AP or dual-enrollment credit, complete an integrated 5-year degree, start the exam before graduating, and work in accounting while testing can finish in about 4 years. States offering a 120-hour pathway plus 2 years of experience can also shorten the education stage. The floor is set mainly by the experience requirement.

How long do you have to pass all four CPA exam sections?

After you pass your first section, you have a fixed credit window to pass the other three. That window was 18 months historically and is now 30 months in most jurisdictions as of 2026. If you miss the deadline, your earliest passed section expires and must be retaken. Adoption is state by state, so confirm your window with your state board.

Is the 150-hour requirement going away?

Not entirely, but it is being supplemented. Rather than eliminating the 150-hour rule, a growing number of states have added an alternative pathway that licenses candidates with a 120-hour bachelor’s degree plus 2 years of experience. This addresses the accountant shortage while keeping the traditional 150-hour route intact. Availability depends on your state and its effective date.

Does work experience count toward the timeline separately?

Often it does not add extra time. The 1 to 2 years of required experience can usually run at the same time as your exam study once you are working in a qualifying role. Many candidates finish the exam during their first year or two on the job, so the experience requirement clears without lengthening the total path.

How long does the CPA exam itself take on test day?

Each of the four sections is a 4-hour exam, for 16 hours of total testing time. Sections are taken on separate days, and testing is available year-round under continuous testing. Score release follows a set schedule, typically a few weeks after you sit, which factors into how quickly you can move to the next section.
