How are the employee and employer TRS and THIS Fund contributions calculated?

Following are examples of the calculation of the employee and employer TRS and THIS contributions for the 2016-17 school year.

Example:

District A is obligated per a negotiated agreement to pay the 9.0 percent retirement contributions for full-time teachers.

2016-17 - A teacher has a base contract of $33,000. In addition, he is the basketball coach and earns $2,000. Base earnings and the 9.0 percent retirement contribution are paid from Title 1.

• Creditable earnings: 
  ($33,000 + $2,000) x 1.098901 = $38,461.54
• Employee contributions: 
  $38,461.54 x 9.0% = $3,461.54
• Employer contribution for member benefit increase:
  $38,461.54 x 0.58% = $223.08
• Employee THIS Fund contributions:
  38,461.54 x 1.12% = $430.77
• Employer THIS Fund contributions:
  $38,461.54 x 0.84% = $323.08
• Salaries paid from federal funds: $36,236.73
• 38.54 percent employer contributions due: 
  ($33,000 x 1.098901) x 38.54% = $13,976.04

Example:

At District B the teachers pay their own 9.0 percent retirement contributions.

2016-17 - A teacher has a base contract of $33,000. In addition he is the basketball coach and earns $2,000. Base earnings only are paid from Title 1.

• Creditable earnings: 
  $33,000 + $2,000 = $35,000.00
• Employee contributions: 
  $35,000 x 9.0% = $3,150.00
• Employer contribution for member benefit increase:
  $35,000 x 0.58% = $203.00
• Employee THIS Fund contributions:
  $35,000 x 1.12% = $392.00
• Employer THIS Fund contributions:
  $35,000 X 0.84% = $294.00
• Salaries paid from federal funds: $33,000
• 38.54 percent employer contributions due: 
  $33,000 x 38.54% = $12,718.20
