Usury laws are the state and federal rules that cap how much interest a lender can charge on a loan. When a lender goes over the applicable ceiling, the borrower can often wipe out the interest, recover money already paid, or in some states escape the debt entirely. The catch is that the ceiling depends on who the lender is, what the loan is for, and where the lender is chartered, so the same rate can be legal in one arrangement and criminal in another.
How State Interest Rate Caps Work
Every state sets two numbers. The “legal rate” is the default that applies when a loan agreement doesn’t specify interest, and across the country it ranges from roughly 5% to 15%, with most states between 5% and 12%. The “contract rate” is the maximum the parties can agree to in writing, and it tends to be substantially higher. A few states set no contract rate ceiling at all.
The gap matters. A 9% handshake loan in a state with a 6% legal rate is already over the line. A written 18% agreement in a state that allows contract rates up to 24% is fine. To know whether a rate is legal, you have to identify which of the two ceilings applies to your specific loan.
Why Credit Card Rates Ignore State Caps
If state limits were the whole story, credit card rates above 10% or 12% couldn’t exist in most of the country. They exist because of federal preemption. Under 12 U.S.C. § 85, a nationally chartered bank can charge the interest rate allowed by the state where the bank is located, regardless of where the borrower lives.1Office of the Law Revision Counsel. 12 USC 85 – Rate of Interest on Loans, Discounts and Purchases A bank in a state with no ceiling can lend at that rate nationwide.
The Supreme Court confirmed this reading in 1978 in Marquette National Bank of Minneapolis v. First of Omaha Service Corp., holding that a Nebraska bank could charge Minnesota cardholders the higher Nebraska rate.2Legal Information Institute. Marquette National Bank of Minneapolis v. First of Omaha Service Corp., 439 U.S. 299 That decision is why major card issuers cluster in states with permissive interest laws. Congress later extended similar preemption to state-chartered banks and other federally insured depositories through the Depository Institutions Deregulation and Monetary Control Act of 1980, while letting individual states opt out. The practical result: most bank consumer lending is governed by the lender’s home-state law, not the borrower’s.
Loans That Fall Outside Usury Protection
Federal preemption isn’t the only reason a lender might legally charge more than the state cap suggests. Several categories of borrowers and lenders sit outside the general usury framework.
- A majority of states exempt loans made primarily for business, commercial, or agricultural purposes. Someone borrowing $50,000 to start a company usually can’t rely on usury protections the way a personal borrower can.
- Payday lenders, auto-title lenders, and other high-cost creditors typically operate under separate state licensing statutes that authorize rates well above the general ceiling. They aren’t violating usury law; they’re operating under a different law that permits annual rates reaching into the hundreds of percent.
- Some high-cost operations partner with Native American tribes and claim tribal sovereign immunity from state usury and licensing rules. Courts have pushed back where the tribe’s actual role is minimal, but the area remains unsettled.
The business-purpose exemption is the one that most often surprises borrowers, because the legislature assumes commercial borrowers can evaluate credit costs without a statutory safety net.
What Counts as Interest
Lenders don’t always call their charges “interest,” and courts don’t defer to the labels. If a fee is really compensation to the lender for extending credit, it counts toward the ceiling.
Origination fees, discount points, and processing fees paid to the lender are the ones most often reclassified. A $10,000 loan at 10% with a $500 origination fee kept by the lender delivers only $9,500 in usable funds while charging interest on $10,000, which pushes the effective rate above 10%. Courts perform exactly that math. Charges paid to genuinely independent third parties for appraisals, credit reports, or title searches are generally excluded. The line is whether the money goes to the lender (or a lender-controlled entity) or to an unaffiliated service provider.
Default interest provisions, which spike the rate when a borrower misses a payment, get particular scrutiny. Whether the higher default rate is measured against the usury ceiling depends on the state and the contract language, and courts have sometimes held lenders to the exact wording rather than a broader reading.
Interest Rate Protections for Military Servicemembers
Federal law gives active-duty servicemembers two separate protections that cover different debts.
The Servicemembers Civil Relief Act caps interest at 6% per year on debts incurred before the servicemember entered active duty. It covers mortgages, car loans, credit card balances, and other pre-service obligations, and it runs for the entire period of service, plus one year for mortgages. Any interest above 6% is forgiven rather than deferred, and the lender must reduce monthly payments to reflect the cap. To trigger the protection, the servicemember sends the creditor a written request with a copy of military orders, and the request can be made up to 180 days after leaving service. The statute defines “interest” broadly to include service charges, renewal fees, and most other charges except bona fide insurance premiums.3Office of the Law Revision Counsel. 50 USC 3937 – Maximum Rate of Interest on Debts Incurred Before Military Service
The Military Lending Act works differently. Instead of adjusting pre-existing debt, it caps new consumer credit extended to active-duty servicemembers and their dependents at 36%, measured as a “Military Annual Percentage Rate” that folds in fees a standard APR calculation would exclude.4Office of the Law Revision Counsel. 10 USC 987 – Terms of Consumer Credit Extended to Members and Dependents of Members of the Armed Forces Covered products include credit cards, deposit advance products, overdraft lines of credit, and certain installment loans.5National Credit Union Administration. Military Lending Act Vehicle purchase loans secured by the vehicle are excluded.
What Happens When a Loan Is Usurious
Remedies vary by jurisdiction and lender type, but they share a design feature: they’re meant to hurt.
The most common outcome is forfeiture of all interest. When a national bank knowingly charges more than 12 U.S.C. § 85 allows, it forfeits the entire interest the loan carries, and the borrower owes only principal. If the borrower already paid the usurious interest, federal law allows recovery of twice the amount paid.6Office of the Law Revision Counsel. 12 USC 86 – Usurious Interest; Penalty for Taking; Limitations Many states apply a similar structure to non-bank lenders. Some go further and award treble damages, requiring the lender to pay the borrower three times the illegal interest collected.
A handful of states treat a usurious loan as a legal nullity. The borrower owes nothing, principal or interest, and the lender has no way to collect. Courts applying that rule have acknowledged it gives borrowers a strong reason to default, which is the deterrent the legislature intended.
Deadlines to File
Usury claims run out. Under federal law, a borrower suing a national bank for usurious interest must file within two years of the transaction.6Office of the Law Revision Counsel. 12 USC 86 – Usurious Interest; Penalty for Taking; Limitations State limitation periods typically range from one to six years. Miss the deadline and the right to recover overpaid interest disappears, so a borrower who suspects a problem needs to act rather than wait for the loan to mature.
Usury Savings Clauses
Many loan agreements contain a “usury savings clause” saying that if any charge exceeds the legal maximum, the rate automatically drops to the highest lawful rate and any excess already paid applies to principal. Lenders treat them as insurance against usury claims.
Courts are split on whether they work. The general pattern: a savings clause can protect a lender when a loan turned usurious because of an unanticipated future event, such as a variable rate climbing above the ceiling. When the loan was clearly usurious from the start, courts in several states have refused to enforce the clause, on the reasoning that allowing lenders to set any rate and fall back on the clause would gut the usury statute.
Criminal Usury
Usury can be a crime as well as a civil wrong. Federal law reaches the most severe cases through 18 U.S.C. § 892, which targets “extortionate extensions of credit.” A loan is presumed extortionate when, among other factors, it carries an annual rate above 45% and the debtor reasonably believed the creditor had a reputation for collecting through threats or violence.7Office of the Law Revision Counsel. 18 USC 892 – Making Extortionate Extensions of Credit The penalty is a fine, up to 20 years in prison, or both. The statute aims at loan sharking, and the rate alone isn’t enough; prosecutors also have to show the borrower believed the lender would use extortionate collection methods.
Federal RICO adds another route. It defines “unlawful debt” to include debt from a lending business that charges a rate at least twice the enforceable ceiling under state or federal law.8Office of the Law Revision Counsel. 18 USC 1961 – Definitions In a state with a 25% cap, a lender charging 50% or more can face RICO prosecution, with the asset forfeiture and enhanced sentencing that follows.
Several states also treat usury as a standalone crime, classifying it as a felony or misdemeanor depending on the rate. Criminal usury prosecutions are relatively rare because most disputes get resolved civilly, but the statutes remain in force.
Valid-When-Made and Fintech Lending
A loan that carries a legal rate when a bank makes it doesn’t become usurious just because the bank later sells it. That principle, known as the “valid-when-made” doctrine, has been part of American lending law for over a century, and it underpins most bank-fintech partnerships today.
The typical structure: a fintech platform partners with a nationally chartered bank. The bank originates the loan, so the bank’s home-state rate applies under 12 U.S.C. § 85. The bank sells the loan to the fintech, which services it. Because the rate was legal when made, the doctrine holds it stays legal after transfer. The OCC codified this in regulation, confirming that interest permissible under federal law when a loan is made is not affected by subsequent sale or assignment.9eCFR. 12 CFR 7.4001 – Charging Interest by National Banks
The doctrine took a hit in 2015 when the Second Circuit ruled in Madden v. Midland Funding, LLC that a non-bank debt buyer couldn’t invoke National Bank Act preemption of state usury laws. The OCC and FDIC responded with rules explicitly reaffirming valid-when-made, and a federal court upheld those rules in 2022.
The remaining exposure for fintech lending is the “true lender” theory. If a court decides the fintech, not the partner bank, is the real lender, the bank’s federal preemption doesn’t apply. Courts look at who bears the economic risk, who controls the underwriting, and who holds the loans on its books. Where the bank’s role amounts to a rubber stamp, the arrangement is more likely to fail the test, and the loans become subject to the usury law of the borrower’s state.
