Why we built this
Most online calculators are built for a global audience and use formulas that don't apply locally. A car loan calculator using reducing-balance interest will give Malaysians the wrong monthly installment. A generic tax calculator can't handle LHDN's specific reliefs and rebates. A salary calculator that doesn't know about EPF, SOCSO, EIS, and PCB will mislead anyone earning a Malaysian paycheck.
The local sites that do get the formulas right have a different problem: they're loan marketplaces. Their business is selling your information to banks. Every design choice — the email gate, the "compare loans" CTA, the way the result page is laid out — is optimised for conversion, not accuracy.
Kalkulatorapp.com is independent. Every formula is checked against the official source — Bank Negara Malaysia, LHDN, KWSP, the Stamp Act 1949 — and clearly cited. We update the rates whenever the government does, and we explain the maths so you can verify it yourself. We make money from ads and clearly-marked affiliate links, never from your input data.
How accurate are these?
The brackets, contribution rates, and formulas are based on the most recent official sources. That said, individual circumstances vary — bonuses, joint assessment, special reliefs, mid-year changes — so always treat the output as an estimate. For decisions that matter (loan applications, tax filing, retirement planning), confirm the final numbers with a qualified professional or the relevant authority.
If you want to see exactly how each number is calculated, our methodology page documents every formula and links to the official source.
