If you want to become an officer in the Indian Armed Forces, three exams dominate the landscape: NDA, CDS, and AFCAT. Each leads to a commissioned officer career — but at different qualification levels, through different services, and with meaningfully different starting salaries. Here is a complete, no-fluff comparison for 2026.
Quick Overview — Three Exams at a Glance
| Parameter | NDA | CDS | AFCAT |
|---|---|---|---|
| Conducting Body | UPSC | UPSC | Indian Air Force |
| Minimum Qualification | 10+2 (Class 12) | Graduation | Graduation |
| Age Limit | 16.5–19.5 years | 19–24 years (varies) | 20–26 years |
| Services | Army, Navy, Air Force | Army, Navy, Air Force | Air Force only |
| Exam Frequency | Twice a year | Twice a year | Twice a year |
| Commission Type | Permanent | Permanent / Short Service | Permanent / Short Service |
| Starting Rank | Lieutenant / Flying Officer | Lieutenant / Sub-Lieutenant | Flying Officer |
Salary Comparison — Who Gets Paid More?
All three exams commission candidates at Pay Level 10 (₹56,100 basic pay) under the 7th Pay Commission — so the starting basic pay is identical. The real difference is in allowances.
| Post | Basic Pay | MSP | Key Extra Allowance | In-Hand |
|---|---|---|---|---|
| Army Officer (NDA/CDS) | ₹56,100 | ₹15,500 | Field/HRA (varies) | ₹75,000–₹90,000 |
| Navy Officer (NDA/CDS) | ₹56,100 | ₹15,500 | Sea Duty ₹7,000–₹12,000 | ₹85,000–₹1,00,000 |
| IAF Flying Officer (NDA/AFCAT) | ₹56,100 | ₹15,500 | Flying Allowance ₹23,750 | ₹1,05,000–₹1,25,000 |
Winner: AFCAT (IAF Flying Branch). The ₹23,750/month Flying Allowance — paid on top of all standard allowances — makes IAF Flying Officers the highest-paid commissioned officers at the entry level across all three services.
Exam Difficulty Comparison
| Factor | NDA | CDS | AFCAT |
|---|---|---|---|
| Written Exam | Maths (300) + GAT (600) = 900 marks | 2–3 papers × 100 marks each | 100 MCQs × 3 marks = 300 marks |
| Negative Marking | Yes (1/3) | Yes (1/3 or 1/4) | Yes (1 mark) |
| SSB Interview | 900 marks (5 days) | 300 marks (5 days) | AFSB (similar to SSB) |
| Competition Level | Very High (lakhs apply at 12th level) | High | Moderate |
| Easiest Written Exam | — | — | ✅ AFCAT |
| Most Competitive Overall | ✅ NDA | Moderate | Least competitive |
AFCAT has the most accessible written exam — 100 straightforward MCQs covering English, GK, Reasoning, and Numerical Ability. The AFSB (Air Force Selection Board) interview follows the same 5-day SSB format as NDA and CDS.
Career Growth — Long-Term Salary Trajectory
Since all three exams commission at the same Level 10, the long-term career trajectory is determined by service and branch, not the exam taken:
| Years of Service | Army / CDS Officer | Navy Officer | IAF Flying Officer (AFCAT/NDA) |
|---|---|---|---|
| Entry | Lt — ₹75,000–₹90,000 | Sub-Lt — ₹85,000–₹1,00,000 | Flt Officer — ₹1,05,000–₹1,25,000 |
| 6 years | Major — ₹1,00,000–₹1,25,000 | Lt Cdr — ₹1,05,000–₹1,25,000 | Sqn Ldr — ₹1,20,000–₹1,50,000 |
| 13 years | Lt Col — ₹1,50,000–₹1,85,000 | Commander — ₹1,55,000–₹1,90,000 | Wg Cdr — ₹1,80,000–₹2,15,000 |
| 25+ years | General grade — ₹2,00,000+ | Admiral grade — ₹2,00,000+ | Air Marshal — ₹2,40,000+ |
IAF Flying Officers maintain a salary advantage throughout their career because of the Flying Allowance (which increases with rank), making it the highest-paid officer track across all three services — at every career stage.
Which Exam Should You Target?
| Your Profile | Best Exam |
|---|---|
| Studying in Class 12 (PCM) | NDA — earliest entry, full career ahead |
| Graduate (any stream), want Army/Navy | CDS — direct officer entry after graduation |
| Graduate, want to fly fighter jets | AFCAT — highest in-hand salary from Day 1 |
| Graduate with B.E./B.Tech | AFCAT Technical Branch or CDS — both strong options |
| Want permanent commission fastest | NDA (via IMA/INA/AFA) or CDS IMA/INA |
| Want short service first, then decide | CDS OTA (SSC) or AFCAT SSC |
The Bottom Line
All three exams lead to prestigious officer careers — but AFCAT wins on starting salary thanks to the IAF Flying Allowance. NDA wins on career length — joining at 16.5 means you commission at 22 and have the longest possible career trajectory to reach General/Air Marshal grades. CDS is the most flexible — open to graduates of any stream for all three services.
If maximum in-hand salary from day one is your priority: AFCAT (Flying Branch).
If you are still in Class 12 and want the longest military career: NDA.
If you are a graduate wanting Army or Navy: CDS.
All three are excellent — the right choice depends entirely on your age, qualification, and which service you want to serve in.
