Installment loans are legal in California, and most of them have a price ceiling. A licensed lender making a consumer loan of $2,500 to $10,000 cannot charge more than 36 percent annual simple interest plus the Federal Funds Rate. That rule comes from the California Financing Law as amended by AB 539, operative January 1, 2020, according to the state regulator.

There is a catch. Loans made through out-of-state banks may not be bound by that ceiling, and a California court said so this year. If you are weeks from a mortgage closing, the loan also matters for a second reason, covered at the end.

How California caps the cost

The California Financing Law (CFL) requires every finance lender making consumer loans in the state to hold a license from the Department of Financial Protection and Innovation (DFPI). Licensed lenders are exempt from California's general usury limit of 10 percent a year on consumer loans. They follow the Financial Code's own rate schedule instead.

The Federal Funds Rate in that formula is the one published on the first day of the month before the loan is made, as Financial Code Section 22304.5 defines it. Here are the figures as DFPI and the code state them, current as of 2026:

Loan size Rate cap Fees Term
Under $2,500 Tiered by balance: 30% up to $225, falling to 12% on $1,651 to $2,499 Pilot program lenders may charge alternative administrative and delinquency fees Not stated in these sources
$2,500 to $4,999 36% plus Federal Funds Rate Up to $75 administrative fee outside the cap At least 12 months
$5,000 to $10,000 36% plus Federal Funds Rate Administrative fees count toward the cap 12 months to 60 months and 15 days
Over $10,000 Not covered by these sources

The same law bans prepayment penalties on these loans. It requires lenders to report your payments to a credit bureau and to offer free credit education, which you may skip. The 60-month maximum term applies to loans of $3,000 and up.

Where the cap has been tested

On October 17, 2025, DFPI entered a consent order with a licensed lender accused of leaving administrative fees out of its rate math, which pushed loans over the cap. The lender agreed to a $1 million penalty and $218,000 in automatic refunds, National Law Review reported.

The bigger test involved a bank partnership. OppFi's loans were originated by FinWise Bank, a Utah-chartered bank that can use Utah rates nationwide under federal law. DFPI argued that OppFi was the real lender. It sought about $100 million covering roughly 38,000 Californians. The Los Angeles Superior Court sided with OppFi and finalized its ruling on May 19, 2026, according to Business Law Today. DFPI appealed on July 21, 2026, Consumer Finance Monitor reported. Until the appeals court rules, it is not settled whether bank-partner loans priced above 36 percent are allowed in California.

Tribal lenders are a different matter. A 2018 California Supreme Court ruling held that these lenders do not share a tribe's sovereign immunity, according to DebtHammer. DebtHammer says some keep lending in California illegally anyway.

Not a payday loan

A payday loan in California tops out at $300 and 31 days, with no rollovers allowed. It sits outside the 36 percent cap entirely. Those rules are covered in California payday loan law.

Checking a lender before you sign

Any lender making consumer loans to Californians needs a CFL license, and that includes lenders who only operate online. You can confirm a license through DFPI's DOCQNET portal. Nonprofits making zero-interest loans are exempt from licensing, so a nonprofit offering one is not a red flag. The sources here do not detail credit union small-loan terms or state assistance programs.

If you are buying a home soon

California requires these lenders to report your payments to a credit bureau, so your mortgage underwriter will see the loan on your credit report. The monthly payment counts in your debt-to-income ratio, which compares your monthly debts to your income. The deposit and the recurring payments will also show on your bank statements, and underwriters often ask for a letter of explanation about both.

Because California bans prepayment penalties on covered loans, paying the loan off before you apply costs you nothing extra. Ask your loan officer first whether paying it off helps your ratio. Also ask what payoff proof they need, since each lender sets its own documentation rules.
