You cannot start a traditional bank from your garage, but you have real options
Opening a bank in the legal sense—one that takes deposits and makes loans under federal charter—requires millions of dollars in capital, years of regulatory approval, and a board of directors. That path exists, but it is not what most people asking this question actually want to do.
What you probably want is one of three things: to offer banking services without a full bank charter (a fintech or neobank model), to start a credit union, or to understand what a bank charter actually requires. This guide covers what each path involves, who you would work with, and the realistic timeline and cost for each.
Key Takeaways
- A full bank charter requires $10 million to $50 million in startup capital, approval from the Office of the Comptroller of the Currency or your state banking regulator, and takes 18 months to three years.
- Most fintech companies do not hold a bank charter themselves; they partner with an existing bank that holds the charter and takes the regulatory burden.
- A credit union is a member-owned alternative that requires fewer regulatory hurdles than a bank but still needs a charter from the National Credit Union Administration.
- If you want to move money or offer payment services without a bank charter, you will need a money transmitter license, which varies by state and does not let you take deposits.
- The regulatory bodies you deal with are the Office of the Comptroller of the Currency (federal charters), your state banking regulator (state charters), or the National Credit Union Administration (credit unions).
What a full bank charter actually requires
A bank charter is a license from either the federal government (Office of the Comptroller of the Currency) or your state banking regulator that allows you to take deposits, make loans, and call yourself a bank. Getting one is expensive and slow.
You will need a business plan that shows how you will make money, who your customers are, and why you are different from existing banks. You will need a board of directors with banking or finance experience. You will need to prove you have enough capital—the minimum varies by state and by the type of charter you seek, but federal charters typically require $10 million to $50 million in startup capital, depending on the market you are entering and the size you plan to be.
The approval process takes 18 months to three years. During that time, regulators will examine your business plan, your management team, your capital structure, and your risk management systems. They will want to know how you will handle fraud, how you will comply with anti-money-laundering rules, and how you will protect customer deposits. You will pay for lawyers, accountants, and consultants throughout this process.
Once you have a charter, you are subject to ongoing examination by your regulator. You must maintain minimum capital ratios, report your finances quarterly, and follow rules about what you can lend on and how much you can lend to a single borrower.
The fintech model: partnering with an existing bank
Most companies that look like banks but were founded in the last ten years do not actually hold a bank charter. Instead, they hold a money transmitter license or a smaller license, and they partner with a bank that does hold a charter.
Here is how it works: your company builds the app or website and handles customer service. You partner with a bank—often a smaller regional bank or a bank that specializes in fintech partnerships—that holds the charter and takes the regulatory burden. Customer deposits go into accounts at that partner bank, held in the customer's name. Your company makes money by charging fees, earning interest on the spread, or taking a cut of transactions.
This model is much cheaper to start than getting your own charter. You do not need $10 million in capital upfront. You do need a solid business plan, a technology platform, and a partner bank willing to work with you. The partner bank will vet you carefully because they are taking on the regulatory risk.
Examples of this model include many mobile banking apps and neobanks. They are not banks themselves; they are technology companies that partner with banks.
Starting a credit union instead
A credit union is a member-owned financial cooperative. Instead of shareholders, it has members who own it. Instead of maximizing profit, it aims to serve its members' financial needs.
Getting a credit union charter is less expensive and faster than getting a bank charter, but it still requires regulatory approval from the National Credit Union Administration. You will need a charter process, a business plan, and a founding group of members. The capital requirement is lower than for a bank—often $100,000 to $250,000 depending on your state and the NCUA's assessment of your plan—but you still need significant startup funding.
A credit union must serve a defined field of membership: people who work for a certain employer, people who live in a certain area, people who belong to a certain organization, or some combination. You cannot open a credit union that serves anyone in the country the way a bank can.
The approval process takes 6 to 12 months. Once you have a charter, you are subject to NCUA examination and must follow rules about capital, lending, and member protection.
Money transmitter licenses: moving money without a bank charter
If you want to move money between accounts, send remittances, or offer payment services but do not want to take deposits or make loans, you can get a money transmitter license. This is a state-level license, and requirements vary significantly by state.
Some states require $25,000 to $500,000 in net worth or capital. Some require a surety bond. Some require you to pass a background check and prove you have anti-fraud systems in place. Some require all three.
A money transmitter license does not let you take deposits. It lets you hold customer funds temporarily while you move them somewhere else. You cannot offer savings accounts or interest-bearing products.
You will need to register in every state where you operate. If you operate in 50 states, you will need 50 licenses. Each state has its own process, its own fees, and its own renewal cycle.
The real costs and timeline
| Path | Startup Capital | Timeline | Regulatory Body |
|---|---|---|---|
| Federal bank charter | $10 million–$50 million | 18–36 months | Office of the Comptroller of the Currency |
| State bank charter | $5 million–$25 million | 12–24 months | Your state banking regulator |
| Credit union charter | $100,000–$250,000 | 6–12 months | National Credit Union Administration |
| Money transmitter license (single state) | $25,000–$500,000 | 2–6 months | Your state's financial regulator |
| Fintech partnership (no charter) | Varies widely; no regulatory minimum | Depends on partner bank | None (partner bank is regulated) |
The costs above cover only the regulatory and capital requirements. You will also pay for lawyers, accountants, technology infrastructure, and staff. A bank charter process alone can cost $50,000 to $200,000 in professional fees.
If you are starting a fintech company with a bank partner, your costs depend on your business model and technology. You might launch with $1 million to $10 million in funding, or you might need more. You do not face a regulatory capital requirement because your partner bank holds the charter.
Who to contact to get your free guide
If you want a federal bank charter, contact the Office of the Comptroller of the Currency. They have a charter process process and will assign you a licensing specialist who can walk you through the requirements.
If you want a state bank charter, contact your state's banking regulator. Every state has one—usually called the Department of Banking, Division of Banking, or Office of the State Comptroller. They publish their charter process requirements online.
If you want a credit union charter, contact the National Credit Union Administration. They have a charter process process and regional offices that can answer questions about your state's requirements.
If you want a money transmitter license, contact your state's financial regulator. The requirements and process process are different in every state.
If you want to start a fintech company, you do not contact a regulator first. You build your business plan, develop your technology, and then approach banks that offer fintech partnerships. Banks like Evolve Bank, Customers Bank, and others specialize in this model.
Frequently Asked Questions
Can I start a bank with less than $10 million?
Not a traditional bank with a federal charter. Some states allow state charters with lower capital requirements—as low as $5 million in some cases—but you still need millions. A credit union requires less capital, typically $100,000 to $250,000. A fintech company with a bank partner has no regulatory capital requirement, though you will still need funding to build your platform and hire staff.
How long does it actually take to get a bank charter?
Federal charters take 18 to 36 months from process to approval. State charters take 12 to 24 months. Credit union charters take 6 to 12 months. These timelines assume your process is complete and your business plan is solid. Incomplete applications or regulatory concerns can add months or years.
What if I just want to offer payment services, not take deposits?
You can get a money transmitter license in your state. This lets you move money between accounts and send remittances, but not take deposits or offer savings accounts. Requirements vary by state, and you will need a separate license in each state where you operate.
Do I need a board of directors to start a bank?
Yes. A bank charter requires a board of directors, and regulators will examine the board's experience and qualifications. Board members typically need banking, finance, or business experience. You cannot be the sole decision-maker.
What is the easiest path if I want to offer banking services?
Partnering with an existing bank to build a fintech platform is the fastest and cheapest path. You do not need a charter, you do not need $10 million in capital, and you do not face federal regulatory approval. Your partner bank handles the regulatory burden. The tradeoff is that you depend on that bank's willingness to work with you and their pricing for the partnership.
