PH Calculator provides general information and estimation tools for convenience and education. We are not the Social Security System, PhilHealth, Pag-IBIG, BIR, DOLE, or any government agency.
Calculator results are estimates. Actual payroll, contributions, taxes, loan offers, utility bills, and benefits depend on official tables, employer policy, contracts, and your specific situation.
Articles and guides may summarize rules as commonly understood at the time of writing. Laws, circulars, and rates change. Always confirm material facts on official websites and with qualified professionals when decisions matter.
Use of the Site does not create a tax, legal, HR, or financial advisory relationship. You are responsible for how you use the information.
How to use our estimates responsibly
Treat each result as a planning estimate, then compare it with the document that controls your actual situation: your payslip, employment contract, benefit statement, loan disclosure, utility bill, or official agency circular. A calculator can show the usual formula, but it cannot see company-specific rounding rules, pro-rated cutoffs, special deductions, penalties, exemptions, local utility adjustments, or lender underwriting decisions.
For payroll and government contributions, verify the effective date of the table you are using. A result can be mathematically correct for one year and outdated for another. For loans, compare the formal disclosure sheet and amortization schedule before signing. For utilities, use the rate printed on your latest bill when available because tariff components can change by billing period and provider.
Source and correction policy
When a reader reports a possible formula issue, we check the page against official or primary sources where available, such as agency websites, laws, circulars, tariff advisories, and published contribution tables. If we confirm an issue, we update the affected page or formula constants and clarify the assumption for future readers. You can send reports through the contact page with the page URL, inputs used, expected result, and source link.
Some reports are not errors but assumption differences. For example, an employer may apply a different cutoff, classify an allowance differently, round at the semi-monthly level, or use a provider-specific utility charge not visible in a public rate summary. In those cases, we may update the explanation so readers know which assumption to check, even if the calculator formula remains unchanged.
Short version: treat every number as a starting point — not a substitute for official notices, your payslip, or professional advice.
