Your defense career path substantially depends on which exam you choose – Combined Defence Services (CDS), National Defence Academy (NDA), or AFCAT. The Indian Armed Forces conducts these popular defense recruitment exams twice yearly: National Defence Academy (NDA), Combined Defence Services (CDS), and Air Force Common Admission Test (AFCAT).
These exams differ in many ways. The National Defence Academy stands as one of the country’s most prestigious defense exams. Students can join right after 12th grade, while CDS and AFCAT need graduates. The difficulty levels show a clear pattern – NDA tops the list, followed by CDS, and then AFCAT. Your academic strengths should guide your choice between NDA and CDS. The National Defence Academy works best for students who excel in Mathematics and Physics. The salary structure varies too. NDA cadets get a monthly stipend during training of Rs 56,100 during their IMA training.
This piece offers a detailed comparison of these three major defense exams. You’ll learn which path matches your qualifications and career goals in the Indian Armed Forces.
CDS vs NDA: Key Differences and Career Fit
The main difference between NDA vs CDS is how candidates enter the Indian Armed Forces. Let me break down the key aspects to help you choose the right career path.
Eligibility and age criteria
The National Defence Academy welcomes candidates right after their 12th grade, with age limits from 16.5 to 19.5 years. The Army Wing accepts students who passed 12th from any recognized board. The Air Force and Naval Wings need Physics, Chemistry, and Mathematics in 12th.

CDS officers go through shorter but focused training. IMA cadets train for 18 months. Navy officers need 37-40 months, while Air Force officers require 74 months.
NDA vs CDS salary and benefits
NDA and CDS officers earn similar pay after commissioning. Salaries range from ₹56,100-1,77,500 for Lieutenants to ₹2,50,000 (fixed) for Generals. CDS officers might earn slightly better at first due to their higher education.
Who should choose NDA or CDS?
Pick National Defence Academy if you:
- Excel at Mathematics and Physics
- Want to join defense services after 12th
- Like detailed, longer training
Choose Combined Defence Services if you:

The Air Force Academy trains all AFCAT selected candidates. Career paths differ significantly between the two. CDS offers diverse roles across Army, Navy, and Air Force including infantry, naval architecture, and ground duty. AFCAT guides candidates to Flying Branch, Technical Branch, or Ground Duty roles exclusively in the Air Force.
CDS vs AFCAT salary and allowances
Both paths offer similar starting pay scales at Level 10 (₹56,100-₹1,77,500) with Military Service Pay of ₹15,500. Officers take home ₹75,000-₹90,000 monthly. Additional benefits include housing, uniform allowance, and canteen facilities.
Best fit based on career goals
Your career goals should drive your choice. Pick CDS if you want flexibility across Army, Navy, and Air Force. AFCAT suits candidates passionate about Air Force careers or those with aviation-focused technical expertise.
NDA vs AFCAT: Early Entry vs Specialized Focus
NDA and AFCAT provide two distinct paths to join the armed forces. Each path caters to different career goals and aspirations.
Entry after 12th vs after graduation
The National Defence Academy accepts candidates right after 12th grade, with age limits between 16.5 to 19.5 years. AFCAT targets college graduates aged 20-24 years for Flying Branch and 20-26 years for Ground Duty branches. Students must have Physics and Mathematics in 12th grade to qualify for NDA Air Force Wing. The Flying Branch of AFCAT needs graduates with 60% marks and Physics/Mathematics at 12th level.
Exam difficulty and subject focus
AFCAT ranks as the easiest among the three main defense exams, with NDA being the toughest, followed by CDS. The National Defence Academy tests candidates rigorously through Mathematics and General Ability sections that need strong analytical skills. The AFCAT exam focuses on testing candidates’ Reasoning, Verbal Ability, General Awareness, and Numerical Ability.
Training structure and lifestyle
NDA’s training spans three years at the academy and one additional year at respective service academies. AFCAT’s training duration varies – Flying Branch officers train for a year while Non-Technical branches complete their training in about 52 weeks.
NDA and AFCAT difference in career progression
Both paths lead to commissioning as Flying Officers. NDA officers gain seniority benefits since they start their careers earlier. During training, officers from both streams receive a stipend during training of Rs. 56,100 monthly. They also get extra allowances based on their posting location and duties.
Final Comparison: Which Exam is Easier and Better?
Students need to understand how these defense exams differ in difficulty and what they mean for their careers before making their final choice.
