Flat Interest Rate

Interest is calculated on the original principal amount throughout the loan tenure. EMI remains constant, but the effective interest rate is higher.

Reducing Balance Rate

Interest is calculated on the outstanding loan balance. As you pay EMIs, the principal reduces, and so does the interest component. This is the most common method.
