Understanding Credit and Monthly Payments

Understanding Your Credit Payments

When taking out a loan, it's crucial to understand how your monthly payments are calculated and where your money goes each month. A common misconception is that you're just paying back the principal (the amount you borrowed) plus a bit of interest. In reality, the proportion of interest and principal changes every month through a process called amortization.

How it works

The monthly payment is calculated using the standard amortization formula.

Each month, your payment first covers the interest for that month (Current Balance × Monthly Rate). The remainder of your payment goes towards reducing the principal balance. This is why you'll notice in the table above that the interest portion decreases each month while the principal portion increases.
