About This Calculator
This Zambia NHIMA calculator estimates your National Health Insurance Management Authority contribution based on your monthly income. NHIMA provides national health insurance coverage and is a mandatory statutory deduction for formally employed workers, with separate arrangements for the self-employed and voluntary members.
NHIMA Contribution Rates

|---|---|---|---|
| Formal Employee | 1% of gross salary | 1% of gross salary | No cap |
| Self-Employed / Voluntary | 1% of declared income | Not applicable | No cap |
How NHIMA Differs From PAYE and NAPSA
NHIMA is deducted from gross pay but, unlike NAPSA, it does not reduce your taxable income for PAYE purposes. The calculation order for a typical payslip is: gross salary, then NAPSA deducted (which lowers taxable income), then PAYE calculated on the reduced amount, then NHIMA deducted separately from gross pay.
NHIMA Calculation Formula
Employer NHIMA = Gross Monthly Salary × 1%
Total Monthly Contribution = Employee NHIMA + Employer NHIMA
Annual Contribution = Monthly Contribution × 12
Worked Example
Employee NHIMA: K10,000 × 1% = K100.00
Employer NHIMA: K10,000 × 1% = K100.00
Total monthly contribution = K200.00
Total annual contribution = K2,400.00
Who Must Contribute to NHIMA?
- All formally employed workers in the public and private sector
- Employers, who match the employee’s 1% contribution
- Self-employed individuals, who register and contribute based on declared income
- Voluntary members who wish to access NHIMA-covered healthcare services
What NHIMA Covers
NHIMA contributions fund access to healthcare services at accredited public and private health facilities across Zambia, covering outpatient and inpatient care, surgeries, maternity services, and other medical treatment for the contributing member and their registered dependants, subject to NHIMA’s benefit package and accredited facility list.
Frequently Asked Questions
Is there a maximum NHIMA contribution?
No. Unlike NAPSA, NHIMA has no contribution cap. The 1% rate is applied to your full gross salary regardless of how high it is.
Does NHIMA reduce my PAYE tax?
No. NHIMA contributions do not count as a deduction for PAYE purposes. Only approved pension contributions, such as NAPSA, reduce your taxable income.
Who registers self-employed and voluntary members?
Self-employed individuals and voluntary members register directly with NHIMA and contribute based on a declared monthly income, since there is no employer payroll to deduct contributions through.
Are dependants covered under my NHIMA contribution?
Yes. Registered dependants, such as a spouse and children, are typically covered under a contributing member’s NHIMA registration, subject to NHIMA’s registration rules.
