Shift Differential Pay Calculator

Calculate your total earnings when working shifts that receive differential pay, such as night shifts, weekends, holidays, or hazard pay. This calculator supports both percentage-based and flat rate differentials.

$

Your regular hourly wage before any differential

Hours worked at your base rate without differential

Hours worked at the shift differential rate (e.g., night shift, weekend)

%

Percentage added on top of your base rate (e.g., 10% means base rate + 10%)

Enable if you have overtime hours that also receive the shift differential

Understanding Shift Differential Pay

Shift differential pay is extra compensation paid to employees who work less desirable shifts or under challenging conditions. Employers use shift differentials to incentivize workers to fill shifts that might otherwise be difficult to staff.

Types of Shift Differentials

  • Night shift differential: Extra pay for overnight work, typically 10-15% above base rate
  • Weekend differential: Premium pay for Saturday and Sunday work, often 10-20% extra
  • Holiday differential: Extra compensation for working on holidays, sometimes time-and-a-half or double time
  • Hazard pay: Additional pay for dangerous work conditions
  • On-call differential: Extra pay for being available outside regular hours

Example Calculations

Example 1: Night Shift Nurse

  • Base hourly rate: $35.00
  • Night differential: 12%
  • Night shift rate: $35 × 1.12 = $39.20/hour
  • 8 night shift hours = $39.20 × 8 = $313.60

Example 2: Weekend Retail Worker

  • Base hourly rate: $15.00
  • Weekend differential: $2.00 flat
  • Weekend rate: $15 + $2 = $17.00/hour
  • 6 weekend hours = $17 × 6 = $102.00

Example 3: Night Shift with Overtime

  • Base hourly rate: $20.00
  • Night differential: 15%
  • Night shift rate: $20 × 1.15 = $23.00/hour
  • Overtime rate: $23 × 1.5 = $34.50/hour
  • 8 regular night hours + 2 OT hours = ($23 × 8) + ($34.50 × 2) = $253.00
