Prorated Salary Calculator
Work out exactly how much you're owed for a partial month — starting mid-month, resigning early, or unpaid leave — using the actual Employment Act formula, not a rough guess.
Days in October 2026: 31
What you're owed
Monthly salary ÷ actual days in the month × days worked
How this compares to common shortcuts
- If a fixed 26-day divisor were used
- RM 2,884.62
- If a fixed 30-day divisor were used
- RM 2,500.00
Employers may use a fixed divisor like 26 or 30 instead, but only if it pays you the same or more than the statutory calendar-day formula — never less.
The formula behind this
Under Section 18A of the Employment Act 1955 (read together with Section 60I(2)), incomplete-month pay is calculated as: monthly salary ÷ the actual number of days in that calendar month × the number of days worked. The divisor is never a fixed number — it changes between 28, 29, 30 and 31 depending on the actual month.
Frequently asked questions
Is my employer allowed to use a fixed 30-day divisor instead?
Yes, but only if the result is equal to or better than the statutory calendar-day formula. A fixed divisor that pays you less than the statutory amount for that specific month isn't compliant, even if it's written into your contract.
Does this apply to a full month I worked completely?
No — a full calendar month worked in full is paid at your full monthly salary regardless of whether that month has 28, 30 or 31 days. Proration only applies when you're being paid for less than the whole period.
