Question No. 3

An operator engaged in machining certain components receives an ordinary day rate of $160 per day of 8 hours. The standard output for machining the components has been fixed at $0.80 per hour (time fixed for premium bonus). On a certain day the output of the worker on this machine is 800. Find labour cost per 100 pieces and the wages that would have been actually earned by the workman under the following:

1: If a bonus of $19.00 is paid per 100 of extra output.
2: If paid for on straight piece work basis at the standard rate.
3: If Halsey Premium Bonus System is in use.

Solution:

Req. No. 1:

Standard output per hour= 80 pieces
Standard output per day or for 8 hours = 80 x 8 = 640 pieces
Actual output in 8 hours or in a day = 800 pieces
Extra output = 800 – 640 = 160 pieces

Bonus:

For 100 extra output Bonus is = $19.00
For 1 extra output bonus is = $19.100
For 160 extra output bonus is = (19 / 100) x 160 = $30.40
Regular wages for 8 hours = $160.00
+ Bonus= $30.40
Total Wages = $190.40

Per 100 Piece Wages:

For 800 pieces wages = $190.40
For 1 piece wages = $190.40/800
For 100 pieces wages = (190.40 / 800) x 100 = $23.80

Req. No. 2: Straight Piece of Rate

 

Per piece wages = 160 / 640= $0.25
For 800 pieces wages = 800 x 0.25 = $200
Per 100 pieces wages = (200 / 800) x 100 = $25

Req. No. 3: Halsey Premium Bonus System

Standard time for 640 pieces = 8 hrs.
Standard time for 1 piece = 8 / 640
Standard time for 800 pieces = (8 x 800) / 640 = 10 hrs.
Time Taken = 8hrs.
Time Saved or Bonus Hours = 10 – 8 = 2 hrs.

Formula for Halsey Premium Scheme

50% of time saved = 2 x (50 / 100) = 1 hour
Regular Wages = $160.00
Bonus = (1 x 160) / 8 = $20.00
Total Earnings = 160 + 20 = $180.00
Per 100 piece Earnings = (180 / 800) x 100 = $22.50
