How to Calculate Your Payslip Deductions Kenya (Full Guide)
Introduction
Many employees receive a payslip and immediately ask:
"Why is my take-home salary much lower than my gross salary?"
"How are all these deductions calculated?"
"What exactly is PAYE, SHA, NSSF and Housing Levy?"
Understanding your payslip helps you:
- Budget properly
- Verify payroll accuracy
- Understand taxes
- Estimate take-home salary
- Plan financial goals
This guide explains the common deductions in simple steps.
Step 1: Start With Gross Salary
Gross salary is your total earnings before deductions.
This may include:
- Basic salary
- House allowance
- Transport allowance
- Overtime
- Bonuses
- Other taxable benefits
Formula:
Gross Salary = Basic Pay + Allowances + Other Earnings
| Component | Amount |
|---|---|
| Basic salary | KSh 70,000 |
| House allowance | KSh 20,000 |
| Transport allowance | KSh 10,000 |
| Gross salary | KSh 100,000 |
Step 2: Calculate SHA Deduction
Current SHA contribution for salaried employees:
SHA = Gross Salary × 2.75%
Example:
Gross salary:
KSh 100,000
SHA:
100,000 × 2.75%
SHA deduction:
KSh 2,750
Step 3: Calculate NSSF Deduction
NSSF contributions use a tiered structure based on pensionable earnings and
applicable limits.
Because limits and implementation phases can change, employers typically
calculate NSSF using prevailing statutory tables rather than a flat percentage.
Example assumption:
Employee NSSF contribution:
KSh 6,000
Actual values vary depending on current contribution limits.
Step 4: Calculate Housing Levy
Current Housing Levy calculation:
Housing Levy = Gross Salary × 1.5%
Example:
Gross salary:
KSh 100,000
Housing Levy:
100,000 × 1.5%
Housing Levy deduction:
KSh 1,500

Step 5: Calculate Taxable Income
Formula: Gross Salary − Allowable Deductions = Taxable Income
| Item | Amount |
|---|---|
| Gross salary | KSh 100,000 |
| NSSF | KSh 6,000 |
Taxable income:
KSh 94,000
Step 6: Calculate PAYE
Current monthly PAYE bands:
| Taxable Income Band | Rate |
|---|---|
| First KSh 24,000 | 10% |
| Next KSh 8,333 | 25% |
| Next KSh 467,667 | 30% |
| Next KSh 300,000 | 32.5% |
| Above KSh 800,000 | 35% |
Resident personal relief:
KSh 2,400 monthly
Estimated PAYE example:
KSh 20,583
Step 7: Calculate Net Salary
Formula: Net Salary = Gross Salary − Total Deductions
| Deduction | Amount |
|---|---|
| PAYE | KSh 20,583 |
| SHA | KSh 2,750 |
| NSSF | KSh 6,000 |
| Housing Levy | KSh 1,500 |
Total deductions:
KSh 30,833
Net salary:
KSh 100,000 − KSh 30,833
Net Salary = KSh 69,167
Full Payslip Example
Putting it all together:
| Item | Amount |
|---|---|
| Gross Salary | KSh 100,000 |
| PAYE | (20,583) |
| SHA | (2,750) |
| NSSF | (6,000) |
| Housing Levy | (1,500) |
| Net Salary | KSh 69,167 |
