California Unpaid Wage Interest Calculation

May 31, 2025

Employees in California are entitled to fair compensation for their work. However, wage violations—whether intentional or accidental—are common.

When employers fail to pay wages on time, employees have the right to collect not just the unpaid amount but also interest on unpaid wages in California. This interest serves as compensation for the delay and discourages employers from withholding payments.

California has some of the strongest wage laws in the U.S., ensuring employees are protected from wage theft and delayed payments. What laws apply, and how can workers recover the wages they’re owed? Let’s break it down with this Freeburg & Granieri APC guide.

Why California Has Strict Wage Laws

California labor laws are among the most employee-friendly in the nation. The state imposes severe penalties on employers who fail to pay their workers properly.

These laws reflect a broader effort to prevent wage theft, discourage unfair labor practices, and hold businesses accountable for their financial obligations.

How Interest Protects Employees from Wage Theft

Interest on unpaid wages serves two key purposes:

  1. Compensation for Delayed Payment – Employees who wait weeks or months for their wages suffer financial harm. Interest ensures that they are made whole.
  2. Deterrence for Employers – Employers who delay payments risk accumulating significant financial penalties, making it more expensive to engage in wage theft.

What Qualifies as Unpaid Wages?

Employers may fail to pay wages in several ways, some intentional and others accidental. Regardless of the cause, employees have a right to recover both the unpaid wages and accrued interest.

Regular Wages Not Paid on Time

Employees must be paid at regular intervals, usually biweekly or semimonthly. Employers must post and notify employees of the set pay date. If an employer fails to meet these deadlines, the wages are considered unpaid.

Overtime and Double Time Violations

California law mandates overtime pay at 1.5 times the regular hourly rate for hours worked beyond 8 hours in a day or 40 hours in a week. Double time applies after 12 hours in a single workday.

Employers who fail to compensate workers for these extra hours owe unpaid wages and interest.

Missed Meal and Rest Break Compensation

Employees in California must receive uninterrupted meal breaks and rest periods. If an employer denies these, the employee is entitled to one additional hour of pay per missed break.

Commission and Bonus Disputes

If an employer fails to pay earned commissions or contractually promised bonuses, employees can pursue legal claims to recover the unpaid amounts, including interest.

Late Final Paychecks After Termination

California law requires final wages to be paid immediately upon termination or within 72 hours if the employee resigns. Delays result in penalties and interest charges. Waiting time penalties for failure to timely pay all wages at the time of termination (up to 30 days) are a type of statutory interest.

Understanding Interest on Unpaid Wages

Definition of Interest in Wage Claims

Interest is the additional sum employers must pay when they delay wage payments. It accumulates over time and increases the total amount owed to the employee.

How Interest Differs from Penalties

Interest is separate from penalties. While penalties serve as punishment, interest compensates workers for lost financial opportunities. Both may apply in a wage claim.

Why Employers Are Required to Pay Interest

Employers benefit financially when they withhold wages. California law ensures that workers do not bear the cost of these delays by requiring interest payments be paid on improperly paid wage claims.

California Labor Code and Interest on Unpaid Wages

Labor Code Section 98.1 – 10% Interest Rate

California Labor Code § 98.1 mandates a 10% annual interest rate on unpaid wages, significantly higher than federal rates.

Statutory Interest vs. Waiting Time Penalties

Statutory interest applies to all unpaid wages, while waiting time penalties (up to 30 days at 8 hours a day at the regular rate) compensate employees when final paychecks are delayed.

How Interest Is Applied in Wage Claims

Interest accrues daily and continues until the employer pays the full amount.

When Does Interest Start Accruing?

From the Date Wages Were Due

Interest begins accumulating the day wages should have been paid—not the day an employee files a claim.

Employer Attempts to Avoid Accrued Interest

Some employers try to delay payments further to negotiate settlements. However, the law ensures that interest continues accumulating, discouraging this tactic.

How Interest on Unpaid Wages Is Calculated

Understanding how interest on unpaid wages is calculated is crucial for employees seeking to recover not only the wages they are owed but also the interest that compensates for the delay in payment.

California law ensures that workers are paid interest on unpaid wages at an annual rate of 10%, but the calculation process involves several steps and considerations.

California’s 10% Annual Interest Rate

California Labor Code § 98.1 mandates that interest on unpaid wages be calculated at a 10% annual rate. This is a straightforward percentage applied to the amount of unpaid wages, but the way in which it accumulates depends on the time frame over which the wages remain unpaid.

This interest rate is significantly higher than the federal interest rate and is designed to act as a deterrent to employers who withhold wages from their employees.

Daily, Monthly, and Yearly Accrual Examples

Unpaid WagesDaily InterestMonthly InterestYearly Interest
$5,000$1.37$41.67$500
$10,000$2.74$83.33$1,000
$20,000$5.48$166.67$2,000

Factors That May Impact the Total Amount

  • Length of time wages remain unpaid
  • Whether penalties apply alongside interest
  • Whether an employer disputes the claim in court

The Financial Consequences for Employers

Interest Plus Other Legal Penalties

In addition to interest, employers may face waiting time penalties, civil fines, and legal fees.

Why Wage Theft Becomes Expensive for Businesses

Failing to pay employees properly often costs more than simply paying them on time.

Common Wage Violations That Lead to Interest Penalties

  • Paying below the minimum wage
  • Failing to properly pay overtime wages
  • Illegal payroll deductions
  • Failing to reimburse business expenses

Legal Avenues to Recover Interest on Unpaid Wages

  • Filing a wage claim with the Labor Commissioner
  • Suing in civil court

How Interest on Unpaid Wages Affects Different Types of Workers

  • Hourly vs. Salaried Employees – Interest applies equally, regardless of pay structure.
  • Independent Contractors – If misclassified, they can seek unpaid wages.
  • Gig Workers – Increasingly filing claims under California’s AB5 law.

How Employers Can Avoid Interest on Wage Claims

  • Implementing proper payroll systems
  • Conducting regular wage audits
  • Paying final paychecks on time

How Employees Can Strengthen Their Wage Claims

  • Keeping records of work hours and pay stubs
  • Documenting employer communications
  • Seeking legal guidance before filing a claim
