The United Nations uses a unique salary system that differs significantly from most national or private-sector employers. UN compensation is designed to attract qualified staff globally while maintaining equity across duty stations with vastly different costs of living. The system involves a base salary, post adjustment multipliers, dependency allowances, and various benefits — all layered to produce a total package that is competitive internationally. This guide explains how each component works, how to read the UN salary scale, and what factors most affect total compensation.
Key Takeaways
- UN P-grade salary = net base salary + post adjustment (location multiplier) + allowances
- Post adjustment compensates for cost-of-living differences vs. New York reference city
- P-category staff pay no host country income tax; staff assessment equalizes after-tax pay
- Education grant for children and pension contributions (15.8% employer) are major benefits

UN Staff Categories and Grade Levels
The UN Secretariat and affiliated agencies organize staff into distinct categories with different salary scales:
Professional and Higher Categories: • P-1: Entry level professional (typically requires first university degree + 0–2 years experience) • P-2: Junior professional (first degree + 2 years or advanced degree) • P-3: Mid-level professional (advanced degree + 5 years) • P-4: Senior professional (advanced degree + 9 years) • P-5: Senior professional (advanced degree + 10+ years) • D-1: Director (senior management) • D-2: Director (senior management, larger departments) • ASG: Assistant Secretary-General • USG: Under-Secretary-General
General Service (GS) Category: • G-1 through G-7: administrative, clerical, and support staff • Paid on local salary scales (differ by duty station) • New York, Geneva, Vienna, Nairobi, etc. each have separate GS scales
National Professional Officers (NPO): • Recruited locally for professional functions • P-scale duties but compensated on a local scale
P-category staff are internationally recruited and entitled to post adjustment and education grants. GS staff are locally recruited and do not receive post adjustment.
- Professional grades: P-1 (entry) to P-5 (senior) | D-1/D-2 (director) | ASG/USG (executive)
- General Service: G-1 to G-7, locally recruited, different scale per duty station
- P-grade staff receive post adjustment; GS staff do not
- Grade level determines base salary range; within-grade steps provide annual increases
Base Salary: The Foundation of UN Compensation
The UN Secretariat's Professional salary scale is set by the UN General Assembly based on comparisons with the US federal civil service (the 'Noblemaire Principle'). The principle requires the UN to pay at least as well as the highest-paying national civil service among its member states — historically the US federal government.
Base salary structure: • Each grade (P-1 to D-2) has multiple steps (typically 1–13) • Staff advance one step per year until reaching the maximum step • Steps within a grade provide automatic within-grade increments
2024 Professional base salary examples (annual, before post adjustment): • P-1 Step I: ~$47,400/year • P-2 Step I: ~$56,800/year • P-3 Step I: ~$71,200/year • P-4 Step I: ~$89,400/year • P-5 Step I: ~$104,800/year • D-1 Step I: ~$120,500/year • D-2 Step I: ~$138,600/year
Note: these are approximate net base salary figures. The UN reports salaries in net (after staff assessment/tax-equivalent) rather than gross. The base salary is the same regardless of duty station — location is addressed through post adjustment.
- UN salaries follow the Noblemaire Principle: competitive with best-paying civil service (US federal)
- Each grade has multiple steps; step increases awarded annually
- P-3 Step I: ~$71,200 base (net, before post adjustment)
- Same base salary regardless of duty station — post adjustment accounts for location cost
Post Adjustment: Location-Based Cost of Living
Post adjustment (PA) is an additional component that compensates staff for cost-of-living differences between duty stations and New York (the reference city).
How post adjustment works: • Expressed as a percentage of base salary • Added to base salary to determine total net salary • Set by the International Civil Service Commission (ICSC) based on price surveys • Updated periodically based on exchange rate changes and price data
Post adjustment formula: Total salary = Base salary × (1 + Post Adjustment %)
Post adjustment index and multiplier: • The PA index is expressed as a number (e.g., 66.0) • PA multiplier = index ÷ 100 = 0.660 • Salary with PA = Base × (1 + 0.660) = Base × 1.660
Examples of post adjustment indices (approximate 2024): • New York: ~66 (used as reference; actually receives a PA of ~66 because NY is expensive) • Geneva, Switzerland: ~100+ (very high cost of living) • Nairobi, Kenya: ~40–50 • Vienna, Austria: ~60–70 • Bangkok, Thailand: ~35–45 • Beirut, Lebanon: varies significantly with economic instability
P-3 Step I example: • Base: $71,200/year • PA in NY (66%): $71,200 × 1.66 = $118,192/year • PA in Geneva (say 100%): $71,200 × 2.00 = $142,400/year
- Post adjustment compensates for cost-of-living differences vs. New York reference
- Formula: Total salary = Base × (1 + PA index ÷ 100)
- Geneva PA: 100+ (very high) | Nairobi PA: 40–50 (lower cost)
- ICSC updates PA periodically based on surveys and exchange rate movements
Dependency Allowances and Other Benefits
UN staff with dependents receive additional compensation:
Dependency allowances (annual, 2024 estimates): • Spouse allowance: ~$5,000/year net (if spouse not employed at the UN) • Child allowance: ~$5,000/year per dependent child (applies to multiple children) • Secondary dependent (parent): ~$1,200/year
Dependent child definition: • Under 18 years • 18–21 years if in full-time education and claimed by the staff member
Education grant: • For dependent children of P-category staff at duty stations outside home country • Can reimburse substantial education costs (up to $30,000+ per child per year) • One of the most valuable benefits for families with children in private school
Other major benefits: • Health insurance: covered by the UN Joint Staff Pension Fund and UN medical insurance • Pension (UNJSPF): staff contribute 7.9% of pensionable remuneration; UN contributes 15.8% • Home leave travel: economy class travel to home country every 2 years (biennium) • Hazard pay: for staff at non-family duty stations or dangerous locations • Assignment grant: lump sum upon assignment to a new duty station • Rental subsidy: if rent exceeds a threshold relative to salary at some duty stations
- Spouse allowance: ~$5,000/year | Child allowance: ~$5,000/year per child
- Education grant: up to $30,000+ per child/year for staff outside home country
- Pension: staff contribute 7.9%, UN contributes 15.8% of pensionable remuneration
- Health insurance, home leave, assignment grant, hazard pay also provided
Staff Assessment (Tax Equivalent) and Net Salary
The UN does not withhold national income taxes from P-category staff salaries. Instead, it applies 'staff assessment' — a deduction system designed to equalize the after-tax income of staff from different countries.
Why staff assessment exists: • UN staff pay no host country income tax on UN salaries (diplomatic immunity) • Without equalization, staff from high-tax countries would receive more take-home pay than staff from low-tax countries • Staff assessment neutralizes this advantage
How staff assessment works: • The gross salary is notional — not actually paid • Staff assessment is deducted, resulting in the net salary actually paid • The net salary is what appears on your payslip • Different rates apply for single staff vs. staff with dependents
US citizens: special case • American staff members must file US tax returns and pay US income tax on their UN salary • The US is unique — most other countries do not tax their nationals on UN income • The UN provides a 'tax reimbursement' to US citizens through the US Federal Tax Equalization Scheme • The US reimburses the net difference so US staff are not disadvantaged
Result: Net salary (what you actually receive) is what matters for financial planning. UN salaries are reported in net terms, which is equivalent to reporting after-tax income.
- UN staff at P-grade: no host country income tax (diplomatic immunity)
- Staff assessment: a notional deduction to equalize after-tax pay across nationalities
- Net salary = what's actually paid — reported in UN job postings
- US citizens: must file/pay US taxes; UN reimburses through tax equalization scheme
How to Read the UN Salary Scale and Total Package
Putting it all together — sample total package for P-3 Step V in New York:
1. Net base salary (P-3 Step V): ~$78,000/year 2. Post adjustment (NY, index 66): $78,000 × 0.66 = $51,480 3. Net base + post adjustment: $78,000 + $51,480 = $129,480/year 4. Spouse allowance: +$5,000 5. Child allowance (2 children): +$10,000 Total cash compensation: ~$144,480/year
Plus non-cash benefits: • Health insurance (substantial value) • Pension contributions (15.8% employer match) • Education grant (potentially $30,000–$60,000+/year for two children) • Home leave travel
Total package value including non-cash: can be $200,000–$300,000+ for a P-3 with family

Frequently Asked Questions
How is a UN salary calculated?
UN salary = net base salary (determined by grade and step) + post adjustment (base × PA index ÷ 100) + dependency allowances. For example, a P-3 Step I with a spouse in New York: net base ~$71,200 + NY post adjustment (~$47,000) + spouse allowance (~$5,000) = ~$123,200/year. Non-cash benefits (health insurance, pension, education grant) add substantially more value.
Are UN salaries tax-free?
P-category UN staff pay no income tax to the host country where they work. The UN applies its own 'staff assessment' (an internal deduction) to equalize after-tax pay across nationalities. US citizens are an exception — they must file and pay US taxes, but the UN provides tax equalization so they're not worse off. Most other UN staff members are not taxed by their home countries on UN income either.
What is a good UN salary grade?
Entry-level professional positions (P-2, P-3) are competitive with mid-career private sector positions in most countries, especially when post adjustment and benefits are included. P-4 and P-5 offer strong total compensation packages. Director (D-1, D-2) and executive (ASG, USG) levels are very well compensated globally. The value depends heavily on duty station — Geneva and New York have high post adjustments making the take-home pay very high.
What is post adjustment in UN salary?
Post adjustment is an additional percentage of base salary paid to compensate for cost-of-living differences between duty stations and New York (the reference city). Expensive cities like Geneva or Zurich have high post adjustment indices (100+), meaning staff receive significantly more than their base salary. Less expensive duty stations like Nairobi or Bangkok have lower indices (40–50). Post adjustment ensures staff have equivalent purchasing power regardless of where they're assigned.
How do I find the current UN salary scale?
The International Civil Service Commission (ICSC) publishes official salary scales at icsc.un.org. Look for 'Salary Scales and Allowances' under Compensation → Salaries. The UN Secretariat and agencies (UNDP, UNICEF, WHO, etc.) may have slightly different arrangements, but all use the common system scales as a base. Job postings on un.org/careers list the grade level, from which you can look up the applicable base salary and estimate total compensation.
