When you walk into a consumer electronics store or an auto dealership, salesmen often pitch a loan with a seemingly unbeatable rate—for example, "Just 7% Interest!" However, what they are quoting is a Flat Interest Rate, which is one of the most deceptive accounting practices in retail finance.
The Mathematical Trick
In a standard, honest Reducing Balance loan (like a home loan), you only pay interest on the outstanding principal. As you pay your EMIs, your principal shrinks, meaning the interest component shrinks every month. In a Flat Rate loan, the interest is calculated on the original starting principal for the entire duration of the tenure, ignoring the fact that you are paying the money back every month.
The Conversion Reality
As a strict mathematical rule of thumb, a Flat Interest Rate usually equates to an Effective Rate (Reducing Balance Rate) that is nearly double the quoted number. A 7% flat rate on a 5-year car loan actually means you are borrowing money at an oppressive ~12.5% effective interest rate. This tool reverse-engineers the EMI to reveal the true cost of debt.
