The rate of interest calculated on the total loan amount for the entire tenure, and not considering a reduction in the principal amount or any market fluctuations, is known as the flat rate of interest. If you choose a flat rate of interest for your loan, the Effective Rate of Interest is considerably higher than a floating rate of interest. If a borrower wants to set a fixed budget schedule and plan out the repayment schedule accordingly, they will select a Flat rate of interest for the certainty that it offers.

Flat interest rate calculator

The following is the formula to calculate the flat rate of interest –

Text Box: Loan Amount x Number of years x Rate of Interest (p.a.) Interest Payable per Installment = ------------------------------------------------------------------------------- Number of Installments

Suppose you take a loan for Rs. 10 lakhs for five years and a flat interest rate of 10% p.a. The total amount repaid is calculated as –

  • Principal Repayment = Rs. 2 lakhs every year
    Interest = Rs. 1 lakh every year
    Repayment = Rs. 3 lakhs per annum, which means an EMI of Rs. 25000 p.m.

  • Total Repayment over the tenure of five years = Rs. 15 lakhs.
    This means that the Effective Rate of Interest here comes to a whopping 17.27%

    Benefits and drawbacks of flat interest rate

    Benefits –

  • Suitable for planning an accurate budget as the EMI remains constant throughout.

  • Flat interest rates are lower than reducing interest rates. Drawbacks-

  • The Effective Rate of Interest paid by the borrower is considerably higher.

  • The borrower cannot reap the benefit of a reduced rate even if he repays a considerable part of the principal.
Is the flat rate of interest for you?

Flat interest is not popular among the borrowers as the interest rate gets calculated for the whole term on the entire loan amount, even if the borrower repays the loan and the principal amount goes down. When converted to Effective Rates of Interest, as seen above, flat interest rates are almost 1.5 to 2.5 times higher than a reducing rate of interest.

However, which type of interest rate best suits you is your personal preference. A flat rate would be better for someone who needs a stable rate of interest with no fluctuations or changes. It is imperative to assess flat and reducing interest rates and read all the fine print carefully before you opt for any one of them.
