Legal Rate of Interest
What it is
The legal rate of interest is the maximum interest a lender may lawfully charge on a debt. Limits vary by type of debt and jurisdiction and are intended to prevent excessive, predatory rates.
Key points
- Exceeding the legal rate is considered usury and can trigger penalties such as fines or forfeiture of interest and/or principal.
- States set their own interest-rate laws in the U.S., so allowable rates differ by state and by type of loan.
- Some loans (for example, payday loans) may have higher statutory limits than others.
- Lenders and borrowers can sometimes contract around state limits under certain legal frameworks or by choosing governing law.
Usury and consequences
Usury is charging interest above the legal limit. Penalties for usury vary by state and may include civil fines, criminal sanctions, or voiding of the interest (or the entire loan). Because enforcement and remedies differ, actual outcomes depend on state statutes and court decisions.

How jurisdiction matters
Interest-rate rules are generally set at the state level. Examples of jurisdictional variation:
* Some states set a fixed statutory cap.
Others tie the legal rate to a benchmark (for example, a fixed percentage above the federal funds or Federal Reserve rate).
States may also set separate civil and criminal usury thresholds with different limits.
Because of this patchwork, lenders operating across states must account for multiple regimes.

Common exceptions and ways rates can be higher
- Contractual waivers: Borrowers may be asked to sign agreements that waive state protections or specify governing law, allowing higher rates.
- Choice of law and incorporation: Credit card issuers and nationally chartered banks often rely on the usury laws of the state where they are incorporated (or chartered). By incorporating in states with relaxed usury rules, lenders can lawfully apply higher rates to customers in other states.
- Statutory carve-outs: Certain loan types or federally regulated institutions may be subject to different limits or exemptions.
Practical advice
- Check the applicable law: determine which state’s law governs the loan and what statutory caps, if any, apply.
- Read loan terms carefully for choice-of-law clauses or waivers of state protections.
- Compare offers and consider reputable lenders; if a rate seems unusually high, ask how the rate is justified and whether any state exemptions apply.
- Seek legal advice if you suspect a loan is usurious or if enforcement remedies are needed.
Summary
The legal rate of interest caps how much lenders can charge, but actual limits and exceptions vary widely by state, loan type, and contractual terms. Understand the governing law and read loan agreements closely to know the protections available and the risks of usury.
