Same money, same rate (2.00% per month = 24.00% per year), same 24 months — three ways of charging it.
Reducing Balance (EMI)
How banks charge
Loan fully repaid with the last EMI
Flat Rate
Interest on full amount throughout
Loan fully repaid with the last EMI
Interest-Only (Mahajani)
Byaj monthly, principal at end
Plus ₹1,00,000 principal in the final month
At the same quoted rate, interest-only always costs the most (the principal never shrinks) and reducing balance the least. A flat rate sits between — roughly equal to a reducing-balance loan at nearly double the quoted rate. Compare quotes on total paid, never on the quoted percentage.
