Installment Loans in Arizona and What State Law Allows

Installment loans are legal in Arizona. A licensed non-bank lender can charge no more than 36% a year on the first $3,000 you borrow. The limit comes from the Consumer Lenders Act, A.R.S. §§ 6-601 to 6-638. The Arizona Department of Insurance and Financial Institutions (DIFI) licenses the lenders it covers, according to DIFI's Consumer Credit Guide.

If you are also buying a house, the loan matters twice: once for what it costs, and again when an underwriter reads your bank statements.

The Act covers loans of $10,000 or less. Under A.R.S. § 6-632, the limits work like this:

• The cap is 36% a year on loans up to $3,000.
• Above $3,000, it is 36% on the first $3,000 and 24% on the rest.

The only extra charges allowed are in § 6-635:

• An origination fee (a one-time charge for making the loan) of up to 5% of the loan, capped at $150.
• Lien filing fees, where the loan is secured.

The Southwest Center for Economic Integrity's February 2026 factsheet adds three rules:

• A lender cannot charge the origination fee again if it refinances the loan within a year.
• Balloon payments are banned, so every installment must be roughly equal.
• Loans over $10,000 have no cap under the Act.

The term limits come from the SWCEI factsheet. One consumer guide lists the first tier as 25 months and 15 days, so check the statute if the difference matters to you.

The 36% is also not the full price, because the origination fee sits on top of it. The National Consumer Law Center, using data as of September 2025, puts a $500 six-month loan at the cap at an effective APR of about 54%. SWCEI puts a $2,000 two-year loan at about 41% and a $10,000 five-year loan at about 30%. In DIFI's December 31, 2025 rate filings, $500 twelve-month loans ranged from about 5% to 45.9% APR across 30 lenders.

Voters approved Proposition 200 in 2008, and payday lending has been illegal in Arizona since 2010. The Center for Responsible Lending reports two pressures on the 36% cap:

• Lenders have repeatedly pushed bills for high-cost products labeled "installment loans." All have been defeated so far.
• "Rent-a-bank" deals, where a non-bank lender partners with an out-of-state bank to claim it is exempt from state caps. CRL calls these a threat to caps like Arizona's.

Any non-bank lender that makes at least three of these loans a year to Arizona residents must hold a DIFI license. The law reaches anyone who advertises, solicits or makes such loans to consumers in Arizona, so a website is covered too. As of February 2026, 172 lenders held licenses. If a quote runs well past the table above, or the lender does not show up in DIFI's licensee lookup, stop there.

Banks and credit unions fall outside the Consumer Lenders Act. Our sources give no figures for credit union payday-alternative loans or for named Arizona assistance programs. Ask your credit union directly what it offers, and compare the APR it quotes against the 36% ceiling above.

Our sources do not cover mortgage underwriting rules, so this is what to expect in outline. Your lender's rules decide the details.

Bank statements. The loan leaves a trail: a deposit when it funds, then the same debit every month. Expect the underwriter to ask about both, often in a letter of explanation, which is a short signed note saying what the loan was for.

Debt-to-income ratio. The monthly payment counts as debt in this ratio, your monthly debts divided by your monthly income.

Paying it off. Clearing the loan before you apply removes the payment. It also moves cash you may need for closing, so ask your loan officer which helps more.

Timing. The worst option is a new installment loan taken out between approval and closing. Do not open one without telling your lender first.
