A ₹30 lakh loan over 20 years costs ₹26,035 a month and ₹32,48,327 in total interest — again more than the principal itself, which surprises most first-time borrowers.
EMI on ₹30 Lakh at 8.5% for 20 years
₹26,035 / month
Total interest ₹32.48 L over the loan
What this loan size means for you
The reason the interest exceeds the borrowed amount is simple: over two decades, the bank is lending you ₹30 lakh for a very long time, and 8.5% compounded monthly adds up. To keep the EMI affordable you would want net income near ₹65,087 a month. If your income supports a higher EMI, dropping to a 15-year tenure is the single most effective lever to cut that ₹32,48,327 interest figure.

How home loan EMI is calculated
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.
Frequently Asked Questions
What income do I need for a ₹30 Lakh home loan?
As a rule of thumb lenders keep the EMI within about 40% of net monthly income, so a ₹26,035 EMI suggests take-home pay of roughly ₹65,087 a month. Existing loans reduce this headroom.
How much interest will I pay in total?
Over 20 years at 8.5% you repay ₹62,48,327 in all — the original ₹30 Lakh plus ₹32,48,327 of interest.
Is the interest rate fixed or floating?
Most Indian home loans are floating, linked to an external benchmark such as the RBI repo rate. The figures here assume a constant 8.5% for illustration; your EMI changes when the benchmark moves.
Can I reduce the total interest?
Yes — a shorter tenure, a larger down payment, or periodic part-prepayments all cut the total interest, because they reduce either the principal or the time it stays outstanding.
