How is prorated salary calculated?
The standard formula used by most HR departments (and labor laws) is the Calendar Day method.
(Monthly Salary ÷ Days in Month) × Days Worked
For example, if you earn $3,000 and worked 10 days in April (30 days):
($3,000 ÷ 30) = $100 daily rate.
$100 × 10 days = $1,000 payout.
