Built like an instrument, not a brochure.

Every statutory rate and threshold lives in a hash-verified pack citing its official source. Nothing is hard-coded from memory.

Pure functions over exact integer-cent arithmetic. The same inputs produce the same result, every time, on your device.

If a verified rule set cannot be loaded, the calculator says so. It never substitutes a guess, a stale year or a plausible number.

Formulas, intermediate values, assumptions, sources and limitations render beside every figure — not behind a support ticket.

Calculations run client-side. Scenarios save to your browser. No accounts, no cookies, no ads.
