Piece-Rate Earnings Calculation and Product Prioritization Based on Tariff Coefficients

Calculating Piece-Rate Earnings and Determining Optimal Product Focus

This example demonstrates how to calculate piece-rate earnings for a worker producing multiple products with varying tariff coefficients. It also analyzes which product type is most profitable for the employee considering time per unit and potential earnings.

Scenario:

A company uses the following wage rate schedule based on work class and tariff coefficients:

| Class | I | II | III | IV | V | VI | VII | VIII ||---|---|---|---|---|---|---|---|---|| Tariff Coefficients | 1.0 | 1.15 | 1.27 | 1.57 | 1.72 | 2.19 | 2.98 | 3.9 |

Given Information:

• Hourly wage rate for Class I: 150 UAH* Shift length: 10 hours

Worker's Output:

• Product A: 10 units (average time per unit: 12 minutes, Class VIII)* Product B: 27 units (average time per unit: 9 minutes, Class V)* Product C: 35 units (production standard: 20 units per hour, Class IV)

Calculations:

1. Product A:

• Piece-rate per unit: (150 UAH * 3.9) / (10 units / (10 hours * 60 minutes)) = 9.75 UAH per unit* Total earnings: 9.75 UAH per unit * 10 units = 97.50 UAH

2. Product B:

• Piece-rate per unit: (150 UAH * 1.72) / (27 units / (10 hours * 60 minutes)) = 11.61 UAH per unit* Total earnings: 11.61 UAH per unit * 27 units = 313.47 UAH

3. Product C:

• Piece-rate per unit: (150 UAH * 1.57) / 20 units per hour = 7.84 UAH per unit* Total earnings: 7.84 UAH per unit * 35 units = 274.40 UAH

Analysis:

While Product A boasts the highest tariff coefficient (3.9), its longer production time (12 minutes/unit) results in lower overall earnings. Product B strikes a balance with a decent tariff coefficient (1.72) and a faster production time (9 minutes/unit), leading to the highest total earnings (313.47 UAH). Product C, despite a relatively fast production rate, falls short in earnings due to its lower tariff coefficient.

Conclusion:

Based on the analysis of tariff coefficients, time per unit, and total earnings, Product B emerges as the most profitable for the employee to focus on. This highlights the importance of considering both pay structure and production efficiency when maximizing earning potential.
