In Short: Reviewing Kenyan PAYE Calculators (2026)
Kenyan salary calculators differ significantly in accuracy, statutory freshness, and privacy. While top software vendors (such as Aren, Wingubox, and Workpay) offer tools, several still use outdated NSSF ceilings or fail to treat SHIF and Housing Levy as pre-tax allowable deductions. Our independent calculator is 100% free, runs client-side, and is checked against 10 published test cases.
When calculating your monthly salary or company payroll, using an accurate PAYE calculator is essential. A single algorithmic error—such as ignoring the tax-deductible status of the Affordable Housing Levy—can distort your net pay calculations by thousands of shillings. Here, our PAYE calculator is reviewed neutrally alongside popular tools in the Kenyan market.
How we compared them
To provide an objective review, we evaluated the primary salary calculators ranking on Google Kenya using four rigorous criteria:
- Statutory Rate Freshness: Does the tool apply the 2026 NSSF Upper Earnings Limit (KES 108,000 / KES 6,480 max) or does it still rely on older 2024/2025 caps?
- Deduction Order Accuracy: Does the calculator subtract SHIF (2.75%) and Housing Levy (1.5%) before computing PAYE, as mandated by KRA directives?
- Transparency of Working: Does the site display a complete line-by-line mathematical breakdown or only a solitary final number?
- Data Privacy & Performance: Does the calculation execute entirely client-side without collecting email addresses or sending financial data to remote servers?

Why calculators give different answers
The primary reason two calculators report conflicting take-home salaries for the exact same gross pay is the deduction sequence. For an in-depth breakdown of this math, read our guide on how to calculate PAYE in Kenya and explore our methodology and sources.
