30 Lakh Home Loan EMI: A Complete Calculation Guide
Anurag Sodani • July 3, 2026
A 30 lakh home loan emi is a common financing size for full apartment purchases in many Indian cities. At an indicative 8.5% p.a. rate, a 20-year tenure gives an EMI of roughly ₹26,035, while a 25-year tenure brings it down to about ₹24,157. This guide covers the EMI formula, a worked example, the factors shaping your monthly payment, and a full 15-year repayment schedule.
What Is Home Loan EMI?
EMI is the fixed monthly payment covering both principal and interest on your loan. Since interest is charged on a reducing balance, your EMI composition shifts from interest-heavy in the early years to principal-heavy toward the end.
The EMI Formula
EMI = [P × R × (1+R)^N] / [(1+R)^N − 1]
Here P = ₹30,00,000, R is the monthly interest rate (annual rate ÷ 12 ÷ 100), and N is the tenure in months.
Worked Example
For a ₹30,00,000 loan at an indicative 8.5% p.a. over 20 years (240 months), the EMI is approximately ₹26,035/month, with total interest of about ₹32,48,327. Choosing a 15-year tenure instead raises the EMI to roughly ₹29,542, but cuts total interest to around ₹23,17,594 — a saving of nearly ₹9.3 lakh.
Factors Affecting Your EMI
- Loan Amount: Higher principal scales EMI proportionally.
- Interest Rate: At this size, even a 0.25% difference matters significantly.
- Tenure: Longer tenure eases monthly EMI but raises lifetime interest.
- Floating vs Fixed Rate: Most Indian home loans are floating, tied to benchmarks like the RBI repo rate.
- Prepayment: Regular prepayments meaningfully cut total interest, since RBI guidelines bar prepayment penalties on floating-rate loans for individuals.
