Enter your monthly gross salary to see your net take-home pay in Zambia after PAYE income tax, the 5% NAPSA pension and 1% NHIMA health insurance. Note: NHIMA is charged on your basic salary only — enter it separately below.
Estimates only — not tax advice. Results are computed from official 2026 tax rules; always verify important decisions with the relevant tax authority.
Step 1 — Enter your monthly gross salary in kwacha (everything: basic + allowances + overtime).
Step 2 — Enter your basic salary separately. This matters: NHIMA health insurance is 1% of basic salary only, while NAPSA and PAYE use the full gross. Mixing them up is the most common Zambian payroll error.
Step 3 — Hit "Calculate Net Pay". NAPSA is capped at K1,861.80/month, so very high earners will see the pension line stop growing.
| Monthly income (ZMW) | PAYE rate |
|---|---|
| 0 – 5,100 | 0% |
| 5,100.01 – 7,100 | 20% |
| 7,100.01 – 9,200 | 30% |
| Above 9,200 | 37% |
NAPSA: 5% of gross, capped at K1,861.80/month. NHIMA: 1% of basic salary (no ceiling). PAYE is computed on the full gross. Sources: Zambia Revenue Authority (zra.org.zm), NAPSA (napsa.co.zm), NHIMA (nhima.co.zm).
Example 1 — K20,000/month (basic K16,000): NAPSA = 5% × 20,000 = K1,000 (under the K1,861.80 cap). NHIMA = 1% × 16,000 = K160. PAYE = 1,030 + 37% × 10,800 = K5,026. Take-home = 20,000 − 1,000 − 160 − 5,026 = K10,954.
Example 2 — K6,000/month (basic K5,000): NAPSA = K300; NHIMA = K50; PAYE = 20% × 900 = K180. Take-home = 6,000 − 300 − 50 − 180 = K5,470.
1. Computing NHIMA on gross salary. It's 1% of basic salary only — using gross overstates the deduction.
2. Missing the NAPSA cap. The 5% stops at K1,861.80/month (ceiling K37,236) — high earners don't keep paying 5% forever.
3. Thinking NAPSA reduces PAYE. PAYE is computed on the full gross; NAPSA and NHIMA come off separately.
Zambia runs three parallel deductions. PAYE is computed on your full gross in four bands (0% to K5,100; 20%, 30%, then 37% above K9,200) — deductions don't shrink it. NAPSA pension takes 5% of salary up to K1,861.80/month (the ceiling is K37,236 of salary); the employer matches it. NHIMA health insurance takes 1% — but of basic salary only, excluding allowances, which is the detail most people miss. All three leave your payslip independently; none reduces the base for the others.
The deductions aren't dead money. NAPSA is your state pension: contributions above the K1,861.80 monthly ceiling simply aren't collected, so high earners effectively get a lower pension rate. NHIMA (the 1% on basic salary) buys you access to covered healthcare at registered facilities across Zambia — if your payslip shows the line, you're entitled to the card. Both are mandatory; neither is optional, and neither reduces your PAYE.
