The categories are adult screening bands, not a diagnosis or a Malaysia/Asian-specific clinical action threshold.

Employer Payroll Cost Calculator Malaysia employer-payroll	Malaysia Employer Payroll Cost · statutory contributions 2026	2026-06-01	2026-08-31	KWSP — EPF Act 1991 Third Schedule Last checked 2026-08-31 · Healthy KWSP — Contribution for non-Malaysian citizen employees Last checked 2026-08-31 · Healthy PERKESO — Contribution rate and wage ceiling Last checked 2026-08-31 · Healthy JTKSM — Minimum wage increased to RM1,700 Last checked 2026-08-31 · Healthy Methodology notes The calculator estimates recurring monthly and annual employer cost for one or more employees sharing the selected wage and profile. It excludes non-statutory employment costs and one-off payroll items. EPF employer contributions use the current KWSP statutory schedule for Malaysian or permanent-resident employees and the applicable non-Malaysian employee rate. SOCSO and EIS employer contributions use the current PERKESO wage classes, age treatment, worker-type eligibility, and RM6,000 insured-wage ceiling. The estimate preserves the rounding behavior of the underlying EPF and PERKESO schedules, then scales the selected per-employee amounts by headcount.

They are not live bank quotes, universal underwriting rules, or approval criteria. CIMB and UOB tools support the affordability-calculator structure; consumer references provide contextual DSR examples. Actual income recognition, DSR, rate, margin, tenure, age cap, and credit decision remain lender-specific.

i-Saraan & EPF Incentive Calculator 2026 epf-incentive	EPF voluntary incentives 2026 · 9 September 2026	2026-01-01	2026-09-09	KWSP — i-Saraan eligibility and incentive FAQ Last checked 2026-09-09 · Healthy KWSP — i-Saraan Plus eligibility and incentive FAQ Last checked 2026-09-09 · Healthy KWSP — i-Suri eligibility and incentive FAQ Last checked 2026-09-09 · Healthy Methodology notes 2026 annual model: i-Saraan matches 20% up to RM500; Plus 20% up to RM600; i-Suri 50% up to RM300. Contribution targets are RM2,500, RM3,000 and RM600 respectively. One scheme is calculated at a time; incentives are not stacked. Lifetime caps are RM5,000 (i-Saraan), RM6,000 (Plus) and RM3,000 (i-Suri), or age 60, whichever comes first. i-Saraan and i-Suri counting begins with 2024 contributions. New Plus participation starts in 2026; prior i-Saraan incentives since 2024 count towards the upgraded Plus cap. These caps cannot bind a normal 2026 annual estimate given the 2024–2025 annual limits, so no prior-incentive input is requested. Eligibility is self-confirmed separately for each scheme, not inferred from occupation alone. Plus requires the qualifying platform route and excludes members receiving mandatory employer contributions; i-Suri uses eKasih status as at 30 November 2025 for 2026. Mid-year scheme changes are outside scope. Estimated incentive = min(eligible contributions × matching rate, annual cap), rounded to sen. Top-up = max(annual cap ÷ rate − contributions, 0). Optional budget splits round up to sen. Processing cut-offs, channel minimums and actual KWSP disbursement rounding are not modeled.

The 2026-01-01 effective date is the latest base-population date, not a claim that every input is current to that date. Height thresholds are an unsourced illustrative heuristic for scenario exploration, not an official statistic.

Below RM3 million is treated as exempt only when none of the published non-individual shareholder, subsidiary, related-company, or joint-venture exceptions applies. For qualifying MSMEs reaching RM3 million from YA2026 onward, the model uses 1 January in the second year following the threshold YA.
Malaysia Fuel Price & BUDI Calculator budi-fuel	budi-fuel-2026-v4	2026-09-01	2026-09-05	data.gov.my / Ministry of Finance: weekly Price of Petroleum & Diesel dataset and OpenAPI Last checked 2026-09-05 · Healthy Ministry of Finance: BUDI95 temporary 200-litre monthly limit before the September restoration Last checked 2026-08-30 · Healthy Ministry of Finance: standard BUDI95 and BUDI Diesel restored to 300 litres, pickup/jeep diesel raised to 400 litres Last checked 2026-09-05 · Healthy Astro Awani: revised BUDI quotas take effect on 1 September 2026 Last checked 2026-08-30 · Healthy Ministry of Finance: BUDI Diesel standard 200-litre quota and 300-litre pickup/jeep tier Last checked 2026-08-29 · Healthy Ministry of Finance: BUDI95 e-hailing additional quota cap remains 800 litres Last checked 2026-08-29 · Healthy Ministry of Finance: official fuel prices for 3-9 September 2026 Last checked 2026-09-05 · Healthy Methodology notes Current and historical prices are requested from the official data.gov.my Ministry of Finance weekly fuel-price dataset; the dated local snapshot is used only when that feed is unavailable. The standard BUDI95 quota remains 200 litres and the approved pickup/jeep BUDI Diesel tier remains 300 litres through 31 August 2026; they switch automatically to 300 and 400 litres respectively at midnight Malaysia time on 1 September 2026. Quota use is modeled within one calendar month and does not carry unused litres into another month. The BUDI Diesel base quota may be used flexibly for eligible diesel or RON95 purchases, so purchases of both fuels share the same monthly balance.

Actual bank repricing dates, reference rates, spreads, rounding, and instalments can differ from this estimate.

Lease duty uses the annualised rent above RM2,400 and applies RM1, RM2, or RM4 per RM250 based on the lease term. Principal security duty uses RM5 per RM1,000 or part thereof, subject to a RM10 minimum in this common-case estimate. Late-stamping penalty is modeled as the higher of RM50 or 10% within three months, and the higher of RM100 or 20% after three months.
