What a Criminal Defense Attorney Costs in St. Louis
Revised September 11, 2026
What is the average retainer fee for a criminal defense attorney?
There is no reliable single average, and any firm number online deserves skepticism. A retainer is an up-front deposit against the lawyer’s work, not a fixed price. What you pay swings with the charge. A misdemeanor at a flat fee sits far below a felony billed hourly against a retainer.
Keep reading ↓Picture a kitchen table in Old Monroe late on a weeknight. A mother has her son’s arrest paperwork spread out, and on a legal pad she has written one word, “retainer,” with a question mark next to it. She has already called two lawyers. One quoted a flat fee for the whole case. The other quoted an hourly rate and asked for a chunk of money up front just to start. The two numbers were nowhere near each other, and neither person really explained why.
That same confusion is playing out all over the metro. A young man in Moscow Mills is trying to work out whether a first-time DWI even needs a private lawyer. A contractor in Roxana caught a felony charge he swears is a misunderstanding, and the first quote he heard made him sit back down. A retiree in Livingston is weighing whether to co-sign for a grandson and wants to know one thing: if the case ends early, does any of the money come back? None of these people is hunting for a bargain. They just want to understand what they are buying.
Here is the honest part. Criminal defense pricing looks messy because the cases themselves are messy. A retainer is not one single thing. A quote is not a bill. And the exact same charge can cost wildly different amounts depending on where it is filed and how far it goes. This guide walks through how criminal lawyers actually charge, what a retainer is and whether you ever see it again, who qualifies for a public defender, and how to talk to a lawyer about money without feeling like you are being difficult.
What is the average retainer fee for a criminal defense attorney in St. Louis?
There is no reliable single average, and any firm number you spot online deserves a little skepticism. A retainer is an up-front deposit against the lawyer’s work, not a fixed price for the case. What you pay swings with the charge. A misdemeanor handled at a flat fee sits far below a felony billed hourly against a retainer, and lumping the two together produces a figure that fits nobody.
The reason you cannot get a clean average is the sheer range of what “a criminal case” means. A minor misdemeanor and a serious felony are both criminal charges, but they are not remotely the same amount of work. A case that ends with a single negotiated plea takes a fraction of the hours a case going to trial does. Averaging those together produces a number that describes nobody’s actual situation.
So when a lawyer quotes you a retainer, treat it as an informed estimate of what it takes to get started and carry the case through its likely path, not a promise of the final total. On a felony billed hourly, the retainer is a starting balance you may need to top up. On a misdemeanor, it may be the whole flat fee. The most useful thing you can do is ask which of those two worlds your quote lives in.
How do criminal defense lawyers charge?
Criminal defense lawyers bill three main ways: a flat fee for a defined case, an hourly rate drawn against a retainer, or a hybrid that blends the two. Which one you are offered depends on the charge and how predictable the work is. A guilty-plea misdemeanor is easy to price as a flat fee. A contested felony usually is not.
A flat fee for a defined case
A flat fee is one agreed price for a defined scope of work. It is common for misdemeanors, first-time DWI cases, and matters likely to resolve with a plea rather than a trial. You know the number going in, which makes budgeting easier when money is tight. Read the scope closely, though. A flat fee often covers the case up to the point of trial, with trial priced separately, because a trial is a different animal entirely.
An hourly rate against a retainer
Hourly billing fits cases nobody can size up front. The lawyer sets an hourly rate, asks for a retainer to begin, and bills their time against that balance as the case moves. When the balance runs low, you replenish it. This structure is common for felonies, for anything that may go to trial, and for cases full of unknowns, like several charges or a co-defendant. It costs more because it usually is more.
What a retainer actually is, and whether you see it back
A retainer is money you pay up front that the lawyer holds and draws from as the work is done. Here is the part people miss. There is more than one kind. A deposit retainer sits in a trust account and belongs to you until it is earned, so the unused portion is generally refundable if the case ends early. A flat or “engagement” fee can be structured as earned when paid, which may not come back the same way.
A grandmother in Mt Olive fronting a retainer for a grandchild should know which kind she is handing over before she writes the check. The rules governing lawyer trust accounts and what counts as an earned fee are real, and they differ between Missouri and Illinois, so confirm the specifics with whoever you hire. You are not being pushy by asking what happens to the unused portion. You are asking a normal question that a straight-shooting lawyer expects and answers plainly.
Why can two quotes for the same charge look so different?
Two honest quotes for the same charge can diverge because the price tracks the work, and the work depends on more than the charge itself. The biggest levers are whether it is a misdemeanor or a felony, whether it resolves in a plea or heads to trial, which court it lands in, how complicated the facts are, and how experienced the lawyer is.
Misdemeanor versus felony is the first fork. Felonies carry more exposure, more procedure, and more hours, so they cost more across the board. The second fork is plea versus trial. A case that settles with a negotiated plea is a very different amount of work from one that runs through motions, witnesses, and a jury. Most quotes assume the likely path, which is why a lawyer asks a lot of questions before naming a figure.
Location matters too. The same charge can move at a different pace in different courts, and a case filed in one county may not run like the same case charged across the river in Illinois. A defendant near North Venice may find the process, the prosecutor’s habits, and the local court calendar all shape how many hours a defense takes. Add expert witnesses, forensic questions, or a mountain of evidence to review, and the number climbs again. None of that is padding. It is the case being bigger than its one-line description.

Can you get a public defender, and who qualifies?
Yes. If you cannot afford a private lawyer, you have a right to a public defender for charges that carry the possibility of jail. Eligibility turns on your income and your finances, and the court decides whether you qualify. You apply through the court after you are charged, usually at or soon after your first appearance.
Public defenders are real criminal trial lawyers, and many are very good at what they do. The catch is caseload. Public defender offices across the metro carry heavy dockets, which can mean less one-on-one time than a private lawyer with fewer clients. That is a genuine trade-off to weigh honestly, not a knock on their skill. For many people it is the right and only realistic option, and there is no shame in using it.
The details differ on each side of the river, because Missouri and Illinois run their own indigent-defense systems, and some places may ask for a small application fee. Confirm the current process with the court that has your case. If you are told you earn just a little too much to qualify, you are not out of options. Many private lawyers will discuss a payment plan, and some will scope the work narrowly to fit a budget. Someone who earns a decent wage but has nothing saved is exactly the person who should ask about both paths.
How should you interview a criminal defense attorney about cost?
Treat the first meeting as an interview, because that is exactly what it is. Shortlist two or three lawyers, describe your situation plainly, and say what you want to understand: the charge, what worries you most, and how the fee would work. Then listen to how each one explains the structure and the likely path, not just the price.
Ask which billing structure applies to your case and why. Ask what the fee covers and, just as important, what it does not, so a separate trial fee does not surprise you later. Ask what happens to any unused retainer if the case ends early. Ask how you will be kept informed and who does the day-to-day work. These are not rude questions. A lawyer who answers them clearly is showing you how they will treat you as a client.
Listen for the difference between a process and a promise. One lawyer will describe how your case is likely to unfold and where the real decisions sit. Another will lead with a guaranteed-sounding outcome. In criminal defense, nobody can promise a result, and the honest ones say so early. This is the same instinct that serves you when you hire any lawyer for a high-stakes problem. Our guide to when you need a tax attorney in St. Louis, not a CPA walks through the same interview mindset for a different kind of trouble.
One last thing. The cheapest quote and the priciest quote are both just numbers until you know what sits behind them. The lawyer who charges more may resolve your case faster or keep you out of a courtroom entirely. The one who charges less may be right-sized for a simple plea. Match the lawyer to the case in front of you, and let the fee be one part of that fit rather than the whole decision.

Frequently asked questions
Is it worth it to hire a criminal defense attorney?
For anything beyond a minor ticket, usually yes. A criminal charge can affect your job, your record, your housing, and your freedom, and the value of a lawyer is measured against those stakes, not just the fee. A good defense lawyer knows the local court, the prosecutor, and the realistic options. For a serious charge, going it alone is often the expensive choice.
How can I afford a criminal defense attorney?
Ask about the fee structure up front and whether a payment plan is possible, because many lawyers offer one. A flat fee on a misdemeanor is easier to budget than an open-ended hourly matter. If money is genuinely tight, ask whether the work can be scoped narrowly, and check whether you qualify for a public defender. Comparing two or three quotes shows you what is normal.
What is the hardest criminal case to beat?
Cases with strong physical evidence, credible witnesses, or a clear recorded statement from the accused are the toughest to defend. Charges backed by video, forensics, or an admission leave less room to create reasonable doubt. That does not make a case hopeless. A skilled lawyer may still challenge how evidence was gathered or negotiate a better outcome, but the odds shape both the strategy and the cost.
How do I get a lawyer if I cannot afford one?
Apply for a public defender through the court that has your case, usually at or soon after your first appearance. The court reviews your income and finances to decide whether you qualify. Missouri and Illinois run separate systems, so confirm the local process. If you land just over the line, ask private lawyers about payment plans or a narrower scope of work.
Does a lawyer keep a retainer fee?
It depends on the kind of retainer. A deposit retainer sits in a trust account and stays yours until the lawyer earns it by doing the work, so the unused balance is generally refunded if the case ends early. A fee structured as earned when paid may not come back the same way. Ask which kind you are paying before you sign.
What are the disadvantages of a retainer fee?
A retainer ties up money before you know the final cost, and on an hourly matter you may have to replenish it as the case runs. If the fee is structured as earned when paid, you might not get the unused portion back. The fix is not to avoid retainers but to understand yours: ask what it covers, how it is billed, and what happens to any balance.
Is a retainer the same as the total cost of my case?
Not usually. On an hourly matter, the retainer is a starting balance the lawyer bills against, and you top it up as the work continues, so the total can end higher. On a flat-fee misdemeanor, the retainer may be the whole price. The only way to know which applies is to ask the lawyer directly which structure your quote uses.
Do criminal defense lawyers offer payment plans?
Many do, especially for flat-fee cases, though the terms vary from one practice to the next. Some ask for a portion up front and spread the rest over the life of the case. Others hold firm on a full retainer for serious matters where the work is unpredictable. It is a fair thing to raise in your first conversation, and a plain answer tells you a lot.
