About CalculatorPH

Our mission

CalculatorPH exists to help Filipinos get the right number, every time. From income tax and payroll contributions to health and everyday math, we build tools that are accurate, localized to Philippine rules and pesos, fast on mobile, and free to use.

What we stand for

• Accuracy first. A wrong number destroys trust. Every formula is tested against boundary cases, and regulated figures (tax brackets, contribution schedules) are versioned, dated, and cited to their official sources.
• Built for the Philippines. Peso amounts, local tax tables, and SSS/PhilHealth/Pag-IBIG schedules by default — not a generic tool with the wrong assumptions.
• Fast and private. Calculations run instantly in your browser. We do not store or transmit the values you type.
• Free and open. No sign-up, no paywall for the core calculators.

How our calculators are built

Each calculator is defined as data and powered by a small, well-tested engine. Rules such as tax rates and contribution tables are stored as dated values with the source and effective date attached, so results stay transparent and easy to keep current when the rules change.

Accuracy and verification

We strive to keep every figure correct and current, but laws, rates, and contribution schedules change. Results are estimates for general information only. Always verify against the relevant official agency — such as the BIR, SSS, PhilHealth, Pag-IBIG, or DOH — before making decisions. See our disclaimer for details.
