Kenya Employer Payroll Cost Calculator

Background.

A job offer quotes a gross salary, but gross salary is neither the employee's take-home pay nor the employer's full monthly cost. This calculator estimates the employer side of that split under the current Kenyan statutory inputs checked for this review. It is an educational payroll estimate, not a KRA assessment or professional tax, legal, or payroll advice; confirm payroll treatment with KRA guidance and a qualified Kenyan professional before acting.

The employer-funded items modelled here are NSSF, the Affordable Housing Levy, and a NITA levy amount entered explicitly. Under the official NSSF Year 4 schedule effective February 2026, the employer matches the employee contribution at 6% of pensionable earnings across Tier I and Tier II, with earnings limits of KES 9,000 and KES 108,000 and a maximum KES 6,480 contribution per side. The Affordable Housing Act applies a 1.5% employer levy on the employee's gross monthly salary. The NITA field defaults to KES 50, but remains editable so the user can reconcile it with the current levy rule that applies to the employer.

SHIF is deliberately absent from the employer-add-on total. The Social Health Insurance Regulations impose the salaried-household contribution on the contributor, calculated at 2.75% of gross salary or wage subject to the statutory minimum. The primary sources checked do not create a matching employer SHIF contribution. The employer may deduct and remit an employee contribution without that deduction becoming an additional employer-funded cost. PAYE is treated similarly for cost classification: it is employee income tax withheld and remitted by the employer, not an extra payment above gross salary.

The primary result adds gross salary, employer NSSF, employer AHL, and the entered NITA amount. For context, the page also runs the existing employee-side PAYE computation from the same gross amount and shows estimated take-home pay and deductions. This side-by-side view is useful for hiring budgets, raise scenarios, and offer comparisons, but it is not a full cost-to-company model. It excludes benefits, insurance, leave accruals, bonuses, workers' compensation, payroll software, recruitment, equipment, and any sector-specific levies or contractual costs.

Use the result for a transparent first-pass calculation, not as an instruction to pay or withhold a particular amount. Check the effective period, confirm that the worker is in scope for each contribution, retain the payroll records supporting the inputs, and reconcile the output with the actual payroll return. Statutory rules and administrative guidance can change, so re-check primary sources when using the page after the stated verification period.

What is kenya employer payroll cost calculator?

The employer cost of an employee in Kenya is the gross monthly salary plus every statutory contribution the employer must pay on top of it — as distinct from the deductions withheld from the employee's own pay. Three contributions sit on the employer's side: the NSSF employer match (mirroring the employee's own NSSF deduction, tiered and capped), the Affordable Housing Levy employer match (1.5% of gross, mirroring the employee's 1.5%), and the NITA industrial training levy (a flat KES 50 per employee per month, entirely employer-funded with no employee equivalent).

Crucially, PAYE and SHIF are not employer costs even though the employer's payroll system processes them. PAYE is the employee's income tax, withheld and remitted by the employer but economically borne by the employee. SHIF, since replacing NHIF in October 2024, is a flat 2.75% deduction from the employee's gross with no statutory employer contribution at all — a genuine asymmetry with NSSF and the Housing Levy, both of which the employer matches.

This calculator is valid for a standard salaried employee under the current statutory schedule. It does not model group life or medical insurance premiums, gratuity or severance provisioning, workplace injury (WIBA) insurance, or any voluntary benefits an employer may separately offer — those are real costs too, but they are contractual or insurance-market costs rather than the statutory payroll add-ons this tool is scoped to.

How to use this calculator.

1. 01Enter the employee's gross monthly salary in KES — the figure on the offer letter or contract.
2. 02Confirm the NITA levy rate shown (KES 50/employee/month by default) — adjust only if NITA has published a new rate.
3. 03Read the primary result: the total monthly cost to the employer, combining gross salary with every employer-borne add-on.
4. 04Review the breakdown — employer NSSF, employer Housing Levy, and the NITA levy — to see exactly where the add-on above gross comes from.
5. 05Compare that to the employee's net take-home pay, shown alongside it, to see the full three-way split: employer cost, gross salary, and employee net.
6. 06Re-run the calculator with a proposed raise to see how much the employer's true cost rises — it is always more than the raise itself, because NSSF and the Housing Levy both scale with gross.

The formula.

The employer's NSSF match uses the identical tier structure as the employee's own deduction: Tier I is 6% of pensionable pay up to KES 9,000, and Tier II is 6% of pay from KES 9,001 up to the KES 108,000 upper earnings limit, so the maximum employer NSSF contribution is KES 6,480/month, reached once gross reaches KES 108,000. The employer's Housing Levy match is simpler — a flat 1.5% of gross with no cap, mirroring the employee's own 1.5% deduction shilling for shilling. The NITA levy does not scale with salary at all: it is a fixed KES 50 per employee per month, so it barely matters for a high earner but is proportionally significant for a low-wage employee.

Adding these three together gives the employer's statutory add-on, and adding that to gross gives the total employer cost — the headline result. Two deductions are deliberately excluded from this total. SHIF (2.75% of gross, minimum KES 300/month) is withheld entirely from the employee with no employer-side match under the Social Health Insurance Act, 2023 — it never touches the employer's cost calculation. PAYE is withheld and remitted by the employer, but it is calculated on and paid out of the employee's own taxable income; treating it as an employer cost would double-count money that was always the employee's.

For contrast, the calculator also runs the same gross salary through the full forward PAYE computation (identical to Quanta's KRA PAYE Calculator) to report the employee's net take-home pay and total employee-side deductions. This produces three distinct, correctly-scoped figures from one gross salary input: what the business pays out in total, what the government-mandated add-ons cost beyond the salary itself, and what the employee actually receives.
