How Reducing-balance interest works
As principal falls, the interest portion generally falls, assuming rate and timing remain unchanged. A quoted flat rate cannot be compared directly with a reducing rate without converting the cash flows.
A rupee example
At 1% monthly interest, a ₹5 lakh outstanding balance creates ₹5,000 of that month's interest, while ₹4 lakh creates ₹4,000.
The example isolates one idea so the arithmetic is visible. Real outcomes can include taxes, fees, cash-flow timing and market movement that the simplified example does not model.
Why it matters for your family
Ask for the annual percentage, repayment schedule and total cost. Families can otherwise choose a seemingly low flat rate that is more expensive in effective terms.
