EMI, or Equated Monthly Instalment, is the fixed amount you pay every month toward repaying a loan, whether it's a home loan, car loan, or personal loan, until the entire loan is fully paid off. Each EMI is a blend of two components — a portion goes toward paying off interest, and the rest goes toward reducing your outstanding principal (the original amount borrowed).
In the early years of a long-tenure loan like a home loan, a much larger chunk of each EMI goes toward interest rather than principal, and this gradually flips over time, with later EMIs paying off more principal and less interest — a pattern called amortisation. Because the EMI amount stays constant (for fixed-rate loans) throughout the tenure, it makes budgeting predictable, which is a big part of why EMIs are the standard way loans are structured in India.
