13th Month Pay Calculator Philippines

Under Presidential Decree No. 851, 13th month pay is one-twelfth (1/12) of the total basic salary you actually earned during the calendar year: total basic salary earned ÷ 12.

Yes. It's based on basic salary — your regular pay for work performed. It generally excludes overtime pay, premium pay, night shift differential, holiday pay, and allowances that aren't treated as part of your regular basic salary.

You're still entitled to a proportionate 13th month pay. Because the formula divides your total earnings by 12 regardless of how many months you worked, it automatically prorates for partial-year employment.

Use the total basic salary you actually received across the year, not your latest monthly rate multiplied by 12. If you got a raise or a pay cut partway through the year, add up each month's actual basic salary first.

Generally, no. Allowances and monetary benefits not considered part of your regular basic salary — such as cost-of-living allowances — are typically excluded, unless your employer has integrated them into basic salary by policy or agreement.

Employers must release 13th month pay on or before December 24 of each year. Some employers pay it in two installments, such as half mid-year and half in December.
