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
