What is a Flat vs Reducing Rate Calculator?

A Flat vs Reducing Rate Calculator is a financial tool that helps borrowers compare the cost of loans under two different interest rate calculation methods: Flat Interest Rate and Reducing Balance Interest Rate. It provides a detailed analysis of the total loan cost, monthly EMI, and interest payments under both methods, enabling individuals to make an informed borrowing decision.

How Does the Flat vs Reducing Rate Calculator Work?

Flat Interest Rate Calculation:

The flat interest rate is calculated on the entire loan amount for the full loan tenure.

Flat Interest Rate = (Loan Amount × Rate of Interest × Loan Tenure) ÷ 100

Monthly EMI (Flat Interest) = (Loan Amount + Total Interest) ÷ (Loan Tenure × 12)

Example:

  • Loan Amount = ₹1,00,000
  • Rate of Interest = 10% per annum
  • Loan Tenure = 12 years

Flat Interest = (1,00,000 × 10 × 12) ÷ 100 = ₹1,20,000

Monthly EMI (Flat Interest) = (1,00,000 + 1,20,000) ÷ (12 × 12) = ₹1,527.78

Reducing Balance Interest Calculation:

In a reducing rate method, interest is recalculated on the remaining principal balance after each payment.

Monthly EMI (Reducing Interest) = [Loan Amount × (Rate of Interest ÷ 12) × (1 + (Rate of Interest ÷ 12)) ^ (Loan Tenure × 12)] ÷ [(1 + (Rate of Interest ÷ 12)) ^ (Loan Tenure × 12) - 1]

Example:

  • Loan Amount = ₹1,00,000
  • Rate of Interest = 10% per annum
  • Loan Tenure = 12 years

Monthly EMI (Reducing Interest) = [1,00,000 × (0.10 ÷ 12) × (1 + (0.10 ÷ 12)) ^ (12 × 12)] ÷ [(1 + (0.10 ÷ 12)) ^ (12 × 12) - 1]

Monthly EMI (Reducing Interest) = ₹1,195.08

Difference in Interest:

Total Interest Saved = Total Interest (Flat) – Total Interest (Reducing)

Example:

  • Total Interest (Flat) = ₹1,20,000
  • Total Interest (Reducing) = ₹72,091.27

Total Interest Saved = ₹1,20,000 – ₹72,091.27 = ₹47,908.73

FAQs on Flat vs Reducing Rate Calculator

  • What is a flat interest rate?
    A flat interest rate means that interest is charged on the original loan amount throughout the tenure, regardless of repayments.
  • What is a reducing interest rate?
    A reducing interest rate means that interest is calculated on the remaining loan balance after each EMI payment, reducing the total interest burden.
  • Which method results in lower EMIs?
    The reducing balance method generally results in lower EMIs because interest is calculated on the decreasing principal amount.
  • Can I switch from a flat rate to a reducing rate?
    Some lenders allow switching, but it may involve additional fees and revised loan terms.
  • Which interest rate method is better?
    The reducing interest rate is usually more beneficial for long-term loans as it reduces the total interest paid over time.
