Amortisation
The gradual repayment of a loan through regular EMIs, where each payment covers the interest accrued for that period plus a slice of outstanding principal. Early EMIs are mostly interest; later EMIs are mostly principal.
Example
On a ₹20 lakh home loan at 9% for 20 years, the first EMI of ₹17,995 covers ₹15,000 interest and ₹2,995 principal; by Year 15 the split reverses.
