Understanding Declining Balance Amortization
The declining balance method calculates loan interest based on the remaining principal balance rather than the original loan amount. As you make payments each month, the portion going toward interest decreases, while the portion paying down the principal increases proportionally.
Formula Used
The periodic payment (EMI) is calculated using the mathematical standard formula:
$$EMI = P \times \frac{r(1 + r)^n}{(1 + r)^n - 1}$$
Where $P$ is the principal loan amount, $r$ is the periodic interest rate, and $n$ is the total number of payment periods.

Frequently Asked Questions
What is a declining balance loan? It is a financing structure where interest charges drop over time as the principal balance shrinks.
How do extra payments help? Adding extra funds straight to the principal cuts down total interest costs significantly and shortens overall tenure.
