Good to know: Companies use one of three methods: (1) calendar days — monthly salary ÷ days in the month × days employed; (2) workdays — monthly ÷ workdays in the month × workdays you worked; (3) daily rate — monthly × 12 ÷ factor × workdays worked. Ask HR which one your company uses; the results usually differ by a few hundred pesos. Based on DOLE rules (Labor Code and the DOLE Handbook on Workers’ Statutory Monetary Benefits), checked November 10, 2026. Your company policy or CBA may give more.
