Author: Alice Gilman. A calendar year and an employer's pay periods do not always coincide precisely. Approximately every 11 years, an employer that pays employees on a biweekly basis will have an extra pay period. An employer that pays employees on a weekly basis will have an extra pay period every five or six years.
Step 3. Divide the new annual salary into the annual pay periods to arrive at the new salary per pay period. The weekly pay period rate would be: $52,000 / 52 weeks = $1,000 per week. The biweekly pay period rate would be: $51,500 / 26 biweekly pay periods = $1,980.77 biweekly. Step 4. Check the effective date of the pay raise to determine if retroactive pay is due.
