DNS vs B.Sc vs B.Tech: Duration, Fees & Sea-Time

|---|---|---|---|
| Diploma in Nautical Science (DNS) | 1 Year Pre-Sea Academy | ₹4.5L – ₹6.5L | 18 Months (mandatory) |
| B.Sc Nautical Science (Deck Officer) | 3 Years Degree Course | ₹6.0L – ₹9.0L | 12 Months (mandatory) |
| B.Tech Marine Engineering (Engine Officer) | 4 Years Degree Course | ₹9.0L – ₹14.0L | 6 Months (mandatory) |

The Honest ROI Picture
Return on Investment: cadet stipend vs officer wage
While training is intensive and costly, the Merchant Navy offers an exceptionally quick recovery of education costs. As a deck cadet during your 12–18 months of sea-time, you earn a monthly stipend of $300–$600 USD (₹25,000–₹50,000) with free food and accommodation on board.
Once you pass the MMD Second Mate/Class IV written and oral examinations and receive your Licence (CoC), you join as a Third Officer or Fourth Engineer. Your starting salary jumps to $2,000–$3,500 USD per month (₹1.6L–₹3L/mo) tax-free. Most cadets recover their full educational loans within their first 12–18 months of sailing as a licensed officer.
