Kenya Employer Payroll Cost Calculator

Background.

A job offer quotes a gross salary, but the gross salary is not what the employee costs the business, and it is not what the employee takes home either — those are three different numbers, and Kenyan payroll law is precise about which statutory deductions land on which side of that split. This calculator answers the employer's half of the question: on top of the gross salary a business agrees to pay, what additional statutory add-ons does the employer have to fund out of its own pocket, and what is the true all-in monthly cost of that employee?

Three deductions have an employer-borne component in Kenya, and each works differently. NSSF (National Social Security Fund) is matched: the employer pays an equal amount to whatever is deducted from the employee, split across Tier I (pensionable pay up to KES 9,000) and Tier II (KES 9,001 to KES 108,000), capped at KES 6,480 per side once gross exceeds the KES 108,000 upper earnings limit. The Affordable Housing Levy is also matched, at 1.5% of gross on each side. The NITA (National Industrial Training Authority) levy is different again — it is a flat KES 50 per employee per month, funded entirely by the employer with no equivalent employee deduction at all, because it is a training levy, not a shared contribution.

What is conspicuously absent from the employer's side is just as important as what is present. SHIF (the Social Health Insurance Fund, 2.75% of gross) has no employer match whatsoever — unlike NSSF and the Housing Levy, it is entirely employee-funded, with the employer acting only as a withholding and remittance agent. PAYE works the same way: the employer deducts and remits the employee's income tax, but that tax is never an employer cost — it is money the employee earned and owes to KRA, simply passing through the employer's payroll system on its way there. A calculator that lumped SHIF or PAYE into an 'employer cost' figure would overstate the true cost of hiring and understate how much of the gross salary is actually employee tax being redirected, not new employer spending.

This calculator keeps that distinction sharp: the primary result is the employer's total monthly outlay (gross plus the three genuinely employer-borne add-ons), broken down line by line, and — for contrast — it also shows what the employee actually nets from that same gross salary once every employee-side deduction is applied. Businesses budgeting for a new hire, comparing the true cost of a raise, or building a headcount forecast need the employer figure; employees comparing offers need the net figure. Seeing both side by side, computed from the identical gross salary, makes the gap between 'what this costs us' and 'what they receive' impossible to miss — and it is usually larger than either party expects.

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.
