Small Claims Interest Calculator - California

For claims filed after January 1, 2024, Cal. Code Civ. Proc. § 116.221 sets the small claims maximum at twelve thousand five hundred dollars ($12,500) for a natural person. A corporation, partnership, limited liability company, or other business entity may sue for only six thousand two hundred fifty dollars ($6,250) in a single case. Interest, court costs, and certain statutory additions may be recoverable in addition to the principal if the judgment allows, but your underlying damages claim must fit within the applicable cap. If you need more, you must sue in civil unlimited court or abandon the excess. Confirm the defendant venue rules and the current Judicial Council forms before filing in 2026.

Small claims is for money judgments within the § 116.221 cap: unpaid debts, security deposits, auto repair bills, property damage, and many consumer or small-business contract disputes. You cannot use small claims for divorce, custody, probate, criminal matters, or injunctive relief that is not a money judgment. Claims above twelve thousand five hundred dollars for individuals—or six thousand two hundred fifty dollars for entities—belong in the regular civil division. Match your theory to the correct statute of limitations: four years for many written contracts under § 337, two years for oral contracts under § 339, and three years for property damage under § 338. This calculator does not determine claim type eligibility.

Yes, but with limits. Under Cal. Code Civ. Proc. § 116.221, a business entity may recover up to six thousand two hundred fifty dollars ($6,250) per small claims action—half the natural-person cap. Cal. Code Civ. Proc. § 116.231 further restricts corporations and similar entities to no more than two small claims filings per calendar year when each claim seeks more than two thousand five hundred dollars ($2,500). An owner may sometimes sue in individual capacity if the injury is personal, but improper party naming can be challenged. Businesses still cannot use attorneys at the initial small claims hearing except as allowed for collections or on appeal under § 116.530. Consult counsel on party structure before filing.

Plaintiffs pay a filing fee under Cal. Code Civ. Proc. § 116.130 based on the amount demanded: thirty dollars ($30) for claims up to one thousand five hundred dollars ($1,500), fifty dollars ($50) for claims over $1,500 through five thousand dollars ($5,000), and seventy-five dollars ($75) for claims above $5,000 up to the jurisdictional maximum. Service of process, mileage, and witness fees may add cost depending on how you serve the defendant. Fee waivers exist for qualifying low-income filers through the court fee waiver program. This calculator focuses on interest modeling, not automatic fee calculation. Check your county Superior Court fee schedule when you file in 2026.

Small claims uses the same limitation periods as other civil actions. Common deadlines include four years for written contracts under Cal. Code Civ. Proc. § 337, two years for oral contracts under § 339, and three years for property damage under § 338. The clock generally starts when the breach or injury occurs, but tolling and discovery rules can extend or shorten effective deadlines in specific fact patterns. Filing in small claims does not pause interest on a separate contract rate if one applies. If you are near a deadline, file promptly and verify service rules. This tool does not compute limitations dates from your facts.

If the defendant was properly served and does not appear at the hearing, the court may hear the plaintiff's evidence and enter a default judgment for provable damages up to the jurisdictional limit. The plaintiff must still prove the amount owed and that service complied with Cal. Code Civ. Proc. § 116.330 et seq. After judgment, collection uses standard enforcement tools—abstracts, levies, and bank levies—in the Superior Court. Post-judgment interest may accrue on the unpaid principal under Cal. Code Civ. Proc. § 685.010 if you obtain a money judgment and the defendant does not pay. The defendant may have limited appeal rights within thirty days. This calculator estimates interest only, not default procedures.
