Free calculators and tools for everyday Philippine problems — pay, tax, grades, loans, dates and units.
A catalogue of 48 tools that answer one question each, quickly, without an account and without a sales pitch.
Most of these calculations are simple. What is usually missing is somewhere trustworthy to do them, with the working shown, that does not want your email address first.
Every tool shows its working. Under each result is the breakdown that produced it — the same figures, in order, so the explanation can never disagree with the number above it.
The calculations live in one place, separate from the pages that display them, and each is covered by tests before it ships. Where two tools use the same rule — a contribution table, a tax bracket — that rule exists once. Copies drift when rates change, and a drifted copy is how a site ends up giving two different answers to the same question.
Philippine rates move: a new circular, a new bracket, a rate that took effect mid-year. Tools that depend on regulation keep every version and pick the one in force for the date you asked about, so a question about 2019 still gets the 2019 answer after the 2026 rules land.
Where a period has no schedule at all, the tool says so and refuses to answer. A confidently wrong payslip is worse than no payslip.
Calculations run in your browser. Your salary, your date of birth, your weight and your loan balance are never sent to us, because there is no endpoint that would accept them. What is kept is small and named: your light or dark theme choice, stored on your device, and one cookie recording whether you are reading in Filipino or English. Neither identifies you. There is no analytics, no tracking pixel, no third-party tag and no sign-in. The privacy policy has the detail.
Display advertising, eventually. Advertising is not running yet. When it does, it will not touch what you typed into a calculator, and it will not decide what a tool tells you.
If a figure looks wrong, it might be. Tell us through the contact page and it gets looked at before anything else on the list.
