Maximum Interest Rates by State and Where Usury Caps Apply

Maximum Interest Rates by State: What High-Net-Worth Borrowers Actually Need to Know

Maximum interest rates by state matter far more in private lending contexts than in institutional ones. If you're structuring a family loan, seller-financing real estate, or acting as a hard money lender, state usury law is the governing framework. If you're borrowing from a national bank, federal preemption likely overrides your state's caps entirely. Knowing which regime applies to your transaction is the starting point.

Most articles on this topic are written for someone shopping payday loans. This one is written for someone who might be on either side of a private credit arrangement, structuring intra-family wealth transfers, or evaluating hard money deals across multiple states.

Why Federal Preemption Makes State Usury Caps Mostly Irrelevant for Institutional Lending

The practical scope of state usury law narrowed dramatically in 1980. The Depository Institutions Deregulation and Monetary Control Act (DIDMCA) granted federal preemption to bank-issued credit, allowing federally chartered institutions to export the interest rate of their home state to borrowers anywhere in the country. The Cornell Law School Legal Information Institute confirms this directly: state usury law is primarily relevant today in non-bank lending contexts.

This is why nearly every major credit card issuer is chartered in Delaware or South Dakota. Both states have no statutory usury ceiling on most loan categories. The U.S. Supreme Court laid the groundwork in Marquette National Bank of Minneapolis v. First of Omaha Service Corp. (1978), holding that national banks may charge the rate permitted in their home state regardless of where the borrower lives.

The Office of the Comptroller of the Currency reinforces this: federally chartered national banks and federal savings associations are generally not subject to state usury ceilings at all.

The practical implication for FatFIRE readers: when you borrow from a major bank, a national credit card issuer, or a federally chartered lender, your state's usury cap is largely irrelevant to the rate you'll pay. State law becomes the controlling framework when you step outside that institutional structure, into private notes, family loans, seller financing, and hard money arrangements.

Which States Have No Usury Laws or Interest Rate Caps?

The spectrum is wide. According to the National Conference of State Legislatures (NCSL), state usury statutes vary dramatically, from near-zero restriction to constitutionally embedded rate ceilings.

Arkansas's Constitution (Amendment 89) caps consumer interest at five percentage points above the Federal Reserve discount rate, making it among the most restrictive states for private lending. South Dakota and Delaware sit at the opposite extreme.

For anyone evaluating a private lending arrangement, the governing state's law, not the borrower's home state, is typically what controls. Which state's law governs the contract is a drafting decision with real economic consequences.

What Is the Maximum Interest Rate Allowed by State Law on Personal Loans?

For personal loans made by non-bank, non-licensed lenders, state usury caps are the binding constraint. The variation is significant enough to affect deal structuring.

A few important distinctions apply across states:

Licensed vs. unlicensed lenders. Most states impose stricter caps on unlicensed private lenders than on licensed consumer finance companies. California's general usury cap is 10% for non-exempt lenders, but licensed finance lenders can charge higher rates under the California Financing Law.

Loan size thresholds. Several states apply different ceilings based on loan amount. Florida, for example, caps rates at 18% for loans under $500,000 and 25% for loans above that threshold.

Loan purpose. Business-purpose loans frequently escape consumer usury caps entirely, a critical point covered in the next section.

The CFPB notes that many states exempt certain loan categories from standard usury caps, creating legal pathways for sophisticated borrowers and private lenders to negotiate rates above consumer ceilings. Understanding interest rate caps and protections in your specific state, for your specific loan type, is not optional if you're acting as a private lender.

Can Wealthy Individuals Structure Private Loans Above State Usury Limits Using Commercial Exemptions?

Yes, in most states, and this is one of the most underused planning tools in private credit.

Most states exempt commercial or business-purpose loans above a specific threshold from consumer usury caps entirely. California Civil Code Section 1916.1 exempts loans over $300,000 made for business purposes from the state's usury law. Similar exemptions exist across the country, with thresholds commonly ranging from $25,000 to $500,000 depending on jurisdiction.

The Uniform Consumer Credit Code, adopted in modified form by several states, explicitly carves out commercial and business-purpose loans from its consumer protection framework.

This matters for FatFIRE readers in several concrete scenarios:

• Bridge lending on investment real estate. A private loan to fund a real estate acquisition for investment purposes may qualify as a business-purpose loan, placing it outside consumer usury caps and allowing negotiated rates above the statutory ceiling.
• Private credit to operating businesses. Loans to LLCs, partnerships, or corporations are generally treated as commercial transactions, not consumer loans, regardless of who the ultimate beneficial owner is.
• Hard money lending. Most hard money loans are structured as business-purpose loans specifically to access this exemption. The documentation matters: the loan purpose must be clearly established at origination.

The exemption is not automatic. Lenders who want to rely on a commercial exemption need proper documentation of loan purpose, borrower entity structure, and sometimes a written certification from the borrower. A single misstep can collapse the exemption and expose the lender to usury liability.

Usury Laws by State for Private Lending Agreements and Promissory Notes

When two private parties execute a promissory note, state usury law governs the maximum allowable rate unless a commercial exemption applies. The table below covers key states relevant to high-net-worth private lending activity.

Georgia is notable: without a written contract specifying a rate, the default legal rate is 7%. With a written agreement, the cap rises to 16% for most consumer transactions. This is the kind of detail that matters when you're drafting a promissory note for a family loan or seller-financed deal.

For any private lending arrangement, the choice of governing law clause in the contract is a substantive economic decision, not boilerplate. Selecting a state with no usury ceiling, where the transaction has a legitimate connection to that state, can materially affect the permissible rate structure. This warrants a conversation with a commercial attorney before the note is drafted.

How State Interest Rate Limits Apply to Hard Money Loans and Private Mortgages

Hard money lending occupies a specific niche in this framework. Most hard money loans are real estate secured, short-term, and made to borrowers who are acquiring or improving investment properties. That combination typically triggers the business-purpose exemption in most states.

Rates on hard money loans commonly range from 8% to 15% annually, with origination fees of 1% to 4%. In states with strict consumer usury caps, those rates would be illegal for consumer loans. The business-purpose structure is what makes them permissible.

Private mortgages, including seller financing, are more complex. A seller financing a primary residence to an individual buyer is likely making a consumer loan, subject to consumer usury caps. A seller financing the sale of a commercial property or an investment property to an LLC is almost certainly in commercial-loan territory.

The distinction matters because the consequences of usury violations are severe. In many states, a usurious loan is void or voidable, meaning the lender may lose the right to collect not just the excess interest but potentially the principal as well. Some states allow the borrower to recover all interest paid on a usurious loan.

Understanding how annual interest rates work in the context of private mortgages, including the difference between nominal rate, APR, and effective yield after fees, is essential before structuring any private real estate financing. The stated rate on the note is rarely the whole picture.

What Interest Rate Limits Apply to Margin Lending and Securities-Backed Loans?

This is where FatFIRE readers most frequently interact with credit, and state usury law is largely absent from the picture.

Securities-backed lending, including margin loans and pledged asset lines (PALs), is governed by FINRA and SEC regulations rather than state usury law. Rates on these facilities for high-net-worth clients typically range from SOFR plus 0.5% to SOFR plus 2.5%, depending on collateral quality and relationship size. At current SOFR levels, that puts effective rates in the 5.5% to 8% range for most clients, well above several states' consumer usury caps but entirely legal under the federal securities regulatory framework.

The Federal Reserve's G.19 statistical release tracks prevailing rates on consumer installment loans, providing a useful benchmark for comparing institutional rates against state usury ceilings. The gap is instructive: institutional lenders operating under federal frameworks routinely charge rates that would be usurious under state law for private parties.

For FatFIRE readers using pledged asset lines as a liquidity strategy, a few practical points:

• Rate structure varies by collateral. Concentrated equity positions typically carry higher rates than diversified portfolios. Understanding tiered interest rate structures in these facilities can help you negotiate more effectively.
• SOFR floors matter. Some facilities include interest rate floors and lending practices that set a minimum rate regardless of where SOFR moves. Review the floor provisions carefully.
• These are demand facilities. The lender can call the loan. They are not long-term financing vehicles.

Intra-Family Loans: Navigating the IRS AFR Floor and State Usury Ceilings

Intra-family loans are one of the most efficient wealth-transfer tools available to $5M+ households, and they operate inside a legally defined rate corridor bounded on the bottom by the IRS and on the top by state usury law.

Under IRC Section 1274, private loans between related parties must charge at least the IRS Applicable Federal Rate (AFR) to avoid imputed interest income and potential gift tax consequences. As of 2024, AFR rates range from approximately 4.5% to 5.5% depending on loan term.

The IRS updates AFR monthly. The rate in effect when the loan is made is the rate that governs for the life of the loan for fixed-rate instruments.

The upper bound is the applicable state usury ceiling. In a state like New York, that ceiling is 16% for most private loans. In South Dakota or Delaware, there is no ceiling. The legally compliant rate corridor is the space between the AFR floor and the state usury cap.

For estate planning purposes, the goal is typically to charge the minimum compliant rate (AFR) to maximize the economic benefit transferred to the borrower, usually a child or trust. The borrower receives capital at below-market rates; the lender reports interest income at AFR. The spread between AFR and what the borrower would have paid a commercial lender represents a tax-efficient transfer.

This strategy requires coordination between your estate planning attorney, tax advisor, and the tax lien interest rates by state framework if real property is involved as collateral. Sloppy documentation collapses the structure.

What Is the Maximum Legal Interest Rate on a Promissory Note Between Private Parties?

The answer depends on three variables: the state whose law governs the note, whether the loan qualifies as a business-purpose transaction, and whether either party is a licensed lender.

For consumer promissory notes between private individuals, the state usury cap is the ceiling. For business-purpose notes above the applicable commercial exemption threshold, the ceiling is effectively negotiated, subject to any state-specific commercial usury provisions (which are less common but do exist in states like New York).

A few structural considerations for private promissory notes:

Governing law clause. Specify which state's law governs. Courts generally enforce governing law clauses if the chosen state has a reasonable connection to the transaction. Choosing Delaware or South Dakota for a transaction with a legitimate nexus to those states is a defensible planning decision.

Business purpose certification. If you're relying on a commercial exemption, include a written certification from the borrower confirming the loan proceeds will be used for business purposes. This is standard practice in hard money lending and should be standard in any private commercial note.

Default rate provisions. Many notes include a higher default rate that kicks in upon non-payment. Ensure the default rate also complies with the applicable usury ceiling. A default rate that exceeds the usury cap can void the entire default provision.

Understanding strategies to request lower interest rates is relevant on the borrower side of these arrangements, particularly when negotiating with a private lender who has flexibility that institutional lenders do not.

How to Calculate the Effective Rate on a Private Loan and Verify Usury Compliance

Usury analysis is not always straightforward because the legally relevant rate is not always the stated rate on the note. Many states include fees, points, and other charges in their usury calculation, effectively treating them as interest.

In California, for example, certain fees charged by non-exempt lenders are included in the usury calculation. A note with a 9% stated rate plus a 2% origination fee might be deemed usurious if the fee is treated as interest and the combined effective rate exceeds 10%.

The CFPB distinguishes between the nominal interest rate and the APR, which includes fees and other costs. For usury compliance purposes, the relevant question is what your state includes in its definition of "interest" for usury purposes. That definition varies by state and sometimes by loan type within a state.

Practical steps for verifying compliance on a private note:

1. Identify the governing state's usury statute and its definition of "interest."
2. Determine whether a commercial exemption applies and document it.
3. Calculate the effective rate including all fees and charges using the state's methodology.
4. Confirm the effective rate falls below the applicable ceiling.
5. If the transaction is an intra-family loan, confirm the rate also meets or exceeds the current AFR.

Calculating daily interest rates is particularly relevant for short-term bridge loans and hard money arrangements where interest accrues daily and the effective annualized rate can diverge significantly from the stated annual rate depending on the calculation convention used.

Future Trends in State Interest Rate Regulation

The regulatory picture is not static. Several developments are worth tracking.

The "true lender" doctrine. Courts and regulators have increasingly scrutinized bank-fintech partnerships where a bank originates a loan (to access federal preemption) and then sells it to a non-bank entity. The OCC's "valid when made" rule, finalized in 2020, attempted to codify that a loan valid when made remains valid after sale, but legal challenges have continued in several states. The outcome of this litigation will determine whether fintech lenders can reliably access federal preemption through bank partnerships.

State-level rate cap legislation. Several states have considered or enacted rate caps specifically targeting high-rate consumer lending. Illinois enacted a 36% APR cap on consumer loans in 2021. Similar legislation has been introduced in other states. For private lenders operating in the consumer space, the trend is toward tighter caps.

Federal usury legislation. Congress has periodically considered a national usury cap, most recently proposals to extend the 36% Military Lending Act cap to all consumers. None have passed as of 2024, but the political environment could shift.

For FatFIRE readers, the practical implication is that the commercial exemption structures and governing law strategies that work today require periodic review. A transaction structure that is compliant today may face a different legal environment in three to five years. Build in review triggers when you're structuring long-term private lending arrangements.

Understanding base rate interest fundamentals and how they interact with state-specific floors and ceilings is an ongoing discipline, not a one-time analysis. The same applies to mortgage interest rates and pre-approval strategies for high-value real estate transactions where rate lock timing intersects with state-specific lending regulations.
