Taking a ₹1 crore loan over 30 years minimises the monthly outgo at ₹76,891, but the lifetime interest of ₹1.77 Cr is the highest of any tenure.
Over 30 years you repay ₹2.77 Cr in total against the ₹1 crore borrowed — the interest alone is larger than the loan. The lower ₹76,891 EMI buys eligibility (net income near ₹1,92,228 a month suffices) and cash-flow comfort, which is why younger borrowers often start here. The smart play is to take the 30-year tenure for the low committed EMI, then part-prepay whenever surplus arrives: that converts it into an effectively shorter loan without the rigid high EMI of a 15-year schedule.

Your EMI is fixed by the formula EMI = P × r × (1+r)n ÷ [(1+r)n − 1], where P is the loan principal, r is the monthly interest rate (annual rate ÷ 12) and n is the number of monthly instalments. Each EMI is split between interest and principal repayment: the early years are mostly interest, the later years mostly principal. A longer tenure lowers the EMI but raises the total interest you pay, because the principal is outstanding for longer.
