The Series 66 exam fee is $177. NASAA sets that fee and FINRA collects it when you register, and it is the only mandatory cost of the exam itself. There is no separate sitting fee and no state fee charged to you at the test center. Most candidates have it covered by their sponsoring firm, because the Series 66 is almost always taken as part of getting hired at a broker-dealer. The bigger number to plan for is the full path: the Series 66 is designed to be paired with the Series 7, so the real cost of getting registered is the Series 7 fee plus the SIE fee plus this $177.
How much does the Series 66 exam cost?
The Series 66 exam fee is $177. That single number is the headline, and it is the only mandatory cost of the exam itself. NASAA, the organization that owns the Series 66, sets the fee, and FINRA collects it on NASAA’s behalf when you register. The Series 66 is a NASAA law exam, but FINRA runs the registration and payment plumbing, which is why you pay through FINRA even though the exam is not a FINRA exam.
Nothing is layered on top at the test center. There is no sitting fee, no per-question charge, and no separate state fee that you settle when you show up. You pay $177 once per attempt, and that is the regulator’s price to take the exam. For that fee you sit a 150-minute exam of 100 scored questions (plus 10 unscored pretest questions, 110 in total) and need 73% to pass.
Two different numbers get called “the cost of the Series 66.” The exam fee is the fixed $177 you pay the regulator for this one exam. The cost of getting registered is much bigger, because the Series 66 is a companion exam: it is built to be paired with the Series 7, and you reach the Series 7 through the SIE. This article covers both, but keep them separate: the $177 is just the Series 66 line item.
Who pays the Series 66 exam fee?
Your sponsoring firm, in almost every case. The Series 66 is a companion license taken alongside the Series 7, and the Series 7 requires firm sponsorship to take. That means the typical Series 66 candidate is already a new hire at a broker-dealer going through the licensing process, and the firm treats the $177 as a routine onboarding cost, paid directly or reimbursed after you pass.
Paying out of pocket is the exception, not the rule. Unlike the Series 65, which someone can self-register and take before landing a job, the Series 66 is tied to the sponsored Series 7 path, so a self-funded candidate taking it with no firm behind them is rare. When it does happen, the $177 comes out of your pocket with no reimbursement unless a firm later hires you and chooses to make you whole.
Firm-sponsored candidate
$0 out of pocketThe employing broker-dealer covers or reimburses the $177, often contingent on passing. The fee is treated as a standard onboarding cost alongside the Series 7 and SIE fees, and the firm usually handles the registration paperwork too. This is where nearly every candidate falls.
Out-of-pocket candidate
$177 out of pocketRare for the Series 66, because it pairs with the sponsored Series 7. If you do fund it yourself, the fee is yours, and there is usually no reimbursement unless a firm later hires you and chooses to cover it.
If you are joining a firm, ask the hiring manager or compliance team whether they cover the $177 and any prep costs, and whether reimbursement depends on passing. Policies vary firm to firm. A quick question up front can save you the fee.
What does it cost to retake the Series 66?
Each attempt costs another $177. The fee is per attempt, so if you fall short of the 73% line and re-test, you pay the full $177 again. There is no repeat-attempt discount and no partial credit for the sections you got right last time. A second try is $177, a third is another $177, and the meter keeps running with every attempt.
The money is only half the cost of a retake, though. The bigger penalty is time, because NASAA enforces waiting periods between attempts. If you have already come up short, the Series 66 retake guide lays out the reset plan.
| Attempt | Fee | Wait before you can re-test |
|---|---|---|
| 1st sitting | $177 | n/a |
| After 1st fail | $177 | 30 days |
| After 2nd fail | $177 | 30 days |
| After 3rd fail | $177 | 180 days |
Add it up and the math is blunt: a candidate who fails twice has spent $531 on the Series 66 alone and burned at least 60 days of waiting before a third sitting. A third failure means another $177 and a six-month freeze. The cheapest and fastest path, by a wide margin, is passing on the first attempt.

Make the $177 a One-Time Cost
CertFuel's adaptive practice weights Series 66 questions toward the economics, ethics, and law material where candidates lose points, so you clear the 73% line on the first try instead of paying the fee twice. Full-length practice exams tell you when you are consistently above the line.
Choose Your PathWhat is the total cost of getting registered?
The Series 66 rarely stands alone, so its fee is one line in a bigger bill. The Series 66 combines state agent law and investment adviser representative law into one exam, but it does not qualify you to transact securities by itself. You need a FINRA representative license alongside it, and for the Series 66 that partner is the Series 7. To reach the Series 7, you first pass the SIE. So the real cost of the path is three exam fees, not one.
There is no separate SIE prerequisite unique to the Series 66 to budget for beyond that standard SIE gate: the SIE is the shared entry exam for the whole securities track, and it is the same $100 whether you are heading toward the Series 6, Series 7, or Series 66. Here is how the fees stack.
| Exam | Fee | Role in the path |
|---|---|---|
| SIE | $100 | Entry exam for the whole securities track |
| Series 7 | $395 | General securities rep license (the required partner) |
| Series 66 | $177 | Combined state agent + adviser law |
| Path total (fees) | $672 |
So the mandatory fee total for the standard Series 7 plus Series 66 stack is $672 ($100 + $395 + $177). The Series 66’s $177 is the smallest of the three, which is one more reason not to let a retake inflate it. On top of the fees sit prep materials, which are a separate choice covered below. If your firm reimburses the exam fees and prep, your out-of-pocket cost can be close to zero.
It is easy to assume passing the exam triggers a registration bill you have to pay. At the exam stage it does not. When you pass, your firm registers you with the state or states where you do business, and that filing runs through the CRD system. State registration and notice fees are a firm-and-registration matter handled there, not a charge you settle as a test-taker. The only mandatory cost tied to the Series 66 exam itself is the $177.
How do prep costs compare?
Prep is the one line in the budget where you have real flexibility, and it sits on top of the $672 in fees. The exam fees are fixed by the regulators; what you spend to get ready is entirely your choice. It breaks into two broad approaches.
Free / low-cost prep
$0 and upOpen question banks and library textbooks can carry a disciplined self-starter, especially if you just passed the Series 7 and the law material is fresh. The catch: the Series 66 leans hard on economics, ethics, and adviser law, and self-assembled resources give you no clear signal that you are above the 73% line.
Paid course
varies by providerA paid course bundles structured lessons sequenced to the exam outline, a question bank with explanations, and full-length practice exams into one plan. You spend more up front, but you lower the risk of a costly $177 retake and the waiting period that comes with it.
The tradeoff is between saving money now and lowering retake risk later. Because the Series 66 fee is $177 and a fail also costs you at least 30 days, the practical question is not “what is the cheapest prep,” but “what gets me across the 73% line on the first try.” For a disciplined Series 7 finisher, a light refresher may do it. For most candidates, the structure and readiness signal of a paid course is the cheaper choice once you factor in the cost of failing.
- You just passed the Series 7 and the law material is fresh
- No added cost beyond the exam fees in your path
- You are a disciplined self-starter who builds your own plan
- Open question banks and borrowed textbooks cover the core outline
- You want lessons sequenced to the exam outline, not a pile of resources
- You need explanations on every answer, especially the economics and ethics items
- You want a clear readiness signal before you spend the $177
- One retake plus a 30-day wait would cost you more than the course
Prep Once, Pay Once
CertFuel's adaptive engine and Smart Flashcards focus your Series 66 study on the economics, ethics, and law material that gets tested most, with practice exams that tell you when you are consistently above 73%. Study smarter so the $177 stays a one-time cost.
Choose Your PathRead the $177 in context
Among the NASAA law exams, the Series 66 ($177) sits just below the Series 65 ($187) and above the Series 63 ($147). But the Series 66 is unusual because it is not a standalone credential: it assumes you are also carrying the Series 7 ($395). That is why the fee to compare is not $177 against $187, but the full $672 path against whatever combined stack an alternative route would cost.
- The Series 66 exam fee is $177, set by NASAA and collected by FINRA. That single fee is the only mandatory cost of the exam itself. For it you sit 110 questions in 150 minutes and need 73% to pass.
- Most candidates have the $177 covered by their sponsoring firm, because the Series 66 is taken alongside the sponsored Series 7 during onboarding. Paying out of pocket is the exception.
- Every retake is another $177, plus waiting periods (30 days after the 1st and 2nd fail, 180 days after the 3rd). Passing the first time is the cheapest path.
- The real cost is the path, not the exam. The Series 66 pairs with the Series 7, reached through the SIE, so the standard stack is $100 + $395 + $177 = $672 in fees before prep.
- There is no separate state registration fee on you at the exam stage: the firm files state registration through the CRD system after you pass.
