Systems of Wage Payment — Time Rate and Piece Rate

## Two Fundamental Wage Payment Bases

All wage systems are built on one of two foundations:

BasisPays ForKey Formula
Time RateTime attendedWages = Hours worked × Rate per hour
Piece RateUnits producedWages = Units produced × Rate per piece

---

## Time Rate System (Straight Time Rate)

Formula: Wages = Time worked (including normal idle time) × Rate per unit of time

When to use:

  • Services that cannot be tangibly measured (supervisors, helpers, clerks)
  • Highly skilled precision jobs where speed must not be rushed
  • Output pace is machine-controlled (e.g., automated chemical plants)

Advantages:

  • Simple to understand and administer
  • Guarantees stable income — motivates loyalty
  • Suitable where quality matters more than quantity

Disadvantages:

  • No incentive for workers to increase output
  • Efficient and inefficient workers earn the same
  • Difficult to control labour cost per unit

---

## Piece Rate System (Straight Piece Rate)

Formula: Wages = Number of pieces produced × Piece rate

Advantages:

  • Strong incentive — workers directly benefit from higher output
  • Labour cost per unit is constant and predictable
  • Efficient workers are automatically rewarded

Disadvantages:

  • Quality may suffer as workers prioritise quantity
  • Risk of worker burnout and physical strain
  • Not suitable for quality-sensitive or machine-paced work
  • Workers face income instability if output drops (illness, machine issues)

Worked example

### Example 1

Time Rate Calculation:

Worker rate: ₹80/hour. Shift: 8 hours (including 0.5 hrs normal idle time).

Wages = 8 hours × ₹80 = ₹640 (idle time is included — worker is paid for all attended time)

If a second worker attends 8 hours but produces more than the first — both earn ₹640. No incentive differential.

### Example 2

Piece Rate Calculation:

Piece rate: ₹12 per unit.

Worker A produces 70 units → Wages = 70 × ₹12 = ₹840

Worker B produces 50 units → Wages = 50 × ₹12 = ₹600

Labour cost per unit = ₹12 in both cases (consistent regardless of output volume — a major advantage for budgeting).

Risk: If Worker A rushes to hit 70 units and produces 10 defective units, the cost of rework or rejection must be compared against the speed gained.

⚠️ Common exam mistakes

  • Including idle time in piece rate wages — piece rate is based on output only; idle time during piece rate work is a separate cost issue
  • Assuming piece rate gives a variable cost per unit — it is actually a fixed cost per unit (constant rate per piece), making budgeting predictable
  • Recommending piece rate for all situations — it is inappropriate for quality-critical, precision, or machine-paced work
  • Treating time rate as always less productive — in highly skilled or safety-critical jobs, time rate is the correct choice
