How is reducing balance EMI different from flat rate?

In reducing balance, interest is calculated on the remaining principal which decreases with each payment. In flat rate, interest is calculated on the original principal throughout the loan term, resulting in higher total interest paid.

Which is better: reducing balance or flat rate?

Reducing balance method is typically better for borrowers as you pay less total interest. A 10% reducing balance rate roughly equals a 5-6% flat rate. Always compare the effective interest rate when evaluating loan offers.

How to calculate reducing balance EMI?

The formula is EMI = P × r × (1+r)^n / ((1+r)^n - 1), where P is principal, r is monthly interest rate (annual rate/12/100), and n is the number of monthly installments.

Understanding Reducing Balance Method

What is Reducing Balance?

The reducing balance method (also called diminishing balance) calculates interest on the outstanding loan balance each period. As you pay down the principal with each EMI, the interest component decreases, making this method more cost-effective for borrowers.

Reducing vs Flat Rate

Reducing: Interest calculated on remaining balance
Flat: Interest calculated on original principal
A 10% reducing rate ≈ 5-6% flat rate
Banks typically quote reducing balance rates
NBFCs may quote flat rates - always convert to compare

Benefits of Reducing Balance

Pay less total interest over the loan term
Interest decreases as principal reduces
More transparent calculation method
Standard method used by most banks
Better for prepayment scenarios

Tips for Borrowers

Always ask which method is being used
Convert flat rate to reducing for comparison
Consider making prepayments to save interest
Compare effective annual rate (EAR)
Check for prepayment penalties
