How to calculate SHA deductions?
Multiply your gross monthly salary by 2.75%. If the result is below KES 300, you pay KES 300 instead — that’s the minimum contribution, and there’s no maximum cap.
How is SHA calculated in Kenya?
For formally employed Kenyans, it’s 2.75% of gross monthly salary, with a KES 300 minimum and no upper cap. Self-employed and informal-sector members are assessed differently, through means testing rather than this salary-based formula.
How to calculate SHA?
Take your gross monthly salary, multiply by 2.75%, and compare the result to the KES 300 minimum — whichever is higher is your SHA deduction.
How much does SHA deduct per month?
It depends on your salary. For example, a gross salary of KES 50,000 results in a deduction of KES 1,375. Use the calculator above for your exact figure.
Is SHA deducted before or after tax?
SHA is calculated on your gross salary, before PAYE tax is applied — similar to how the old NHIF deduction worked, but at a percentage rate instead of fixed bands.
Is there a maximum SHA deduction amount?
No. SHA has no upper cap, so high earners contribute proportionally more than they did under NHIF’s old banded system.
Does this calculator work for self-employed or informal workers?
No — this 2.75%-of-salary formula applies to formally employed, payroll-deducted members. Self-employed and informal-sector contributors are assessed through SHA’s means-testing process instead, which considers household income and other factors, not a payslip.
My payslip shows a different SHA deduction than this calculator — why?
Double-check that your employer is using your correct gross salary (not net pay) as the calculation base. If the discrepancy persists, it may be a payroll error worth raising with HR.
