Prorated 13th-Month Pay: Salary Changes, Partial Months and Resignation

Start with coverage and the calendar year

DOLE’s guidance covers rank-and-file private-sector employees who have worked for at least one month during the calendar year, including qualifying employees who have resigned or been terminated. An estimate is not a determination of coverage. Government service, managerial arrangements and other special cases need their own applicable rules.

Use the earnings from the calendar year being checked. If employment spans two years, do not combine both years into one calculation. Keep the pay entitlement calculation separate from when a final payment will be released; confirm release arrangements with payroll for your circumstances.

When monthly salary multiplied by months is sufficient

If basic salary stayed at PHP 30,000 and you earned a full PHP 30,000 in each of eight months, the total basic salary is PHP 240,000. Dividing by 12 gives PHP 20,000 minimum 13th-month pay. The denominator remains 12 even though only eight months of earnings are included.

This shortcut works because the monthly amounts are equal and fully earned. It becomes unreliable if you substitute the latest salary for every earlier month or count a partial month as a full paid month. The calculator’s “Same monthly salary” method is intended for this simpler case.

• Use the 13th-month pay calculator

Example: salary increase and a partly paid month

Suppose your payslips show six months of PHP 20,000 basic pay, five months of PHP 24,000 basic pay, and PHP 12,000 basic pay in the remaining partially paid month. These figures are actual earned amounts, not a proposed daily-pay rule.

Add PHP 120,000 + PHP 120,000 + PHP 12,000 = PHP 252,000 total basic salary. The minimum 13th-month estimate is PHP 252,000 ÷ 12 = PHP 21,000. Using the final PHP 24,000 salary for all 12 months would overstate the earnings in this example.

Select “Actual basic pay total” and enter PHP 252,000 to reproduce the result. The tool does not infer how many days were paid or which payroll divisor your employer uses. Obtain the actual basic-pay amounts first rather than selecting an assumed daily rate.

Example: leaving employment partway through the year

Assume a covered employee earned PHP 28,000 basic pay in each of five full months and PHP 14,000 in a final partial month. The actual total is PHP 154,000. Dividing by 12 gives PHP 12,833.33 after rounding to centavos.

Check whether an advance or earlier 13th-month payment for the same year was already paid before interpreting this as an outstanding balance. The calculator estimates the entitlement from the earnings entered; it does not subtract advances or compute the rest of final pay, unused leave conversion or loan balances.

Choose the basic-pay amounts carefully

DOLE’s explanation excludes items such as overtime, night differential, holiday pay and ordinary allowances from the basic-salary computation unless company policy or an agreement treats them as basic pay. A company may provide a more favorable benefit. Confirm how a disputed component is classified instead of silently including every payslip earning.

For unpaid leave or absences, use the basic salary actually earned as confirmed by payroll. Do not deduct an absence again if the payslip’s basic earnings already reflect it. If a payroll report mixes gross earnings with adjustments, ask for a calendar-year basic-pay summary so the amount is neither inflated nor reduced twice.

Check the tax treatment after computing the entitlement

Proration and taxability are separate. An amount can be correctly prorated and still share an annual tax exemption with other covered benefits. For example, PHP 21,000 13th-month pay plus PHP 80,000 other covered benefits leaves PHP 10,000 of the shared PHP 90,000 ceiling available for this pay. In that example, PHP 11,000 of the 13th-month amount is taxable compensation.

A taxable portion is not the amount of tax to withhold. Confirm earlier covered benefits and the employer’s tax reconciliation. When those figures are unknown, use the basic-pay result for planning and treat the taxability figures as provisional.
