6. How Interest Rate Calculators Work

Interest calculators generally operate on either of the following formulas:

• Simple Interest Formula:
  SI = (P × R × T) / 100
• EMI Formula (for amortized loans):
  EMI = P × R × (1 + R)^N / ((1 + R)^N – 1)

Where:
P = Principal amount
R = Rate of interest per month
N = Number of monthly installments

19. Loan Amortization Schedule: Why It Matters

A loan amortization schedule is an elaborate table detailing the composition of each loan installment (EMI) through time. It breaks down the principal and interest portion for each installment and demonstrates how the loan decreases through time.

Advantages of an Amortization Schedule:

• Helps monitor progress
• Useful in accounting and taxation
• Shows interest-principal shift over time

Sample Table (Year 1):

Month    EMI     Interest  Principal  Balance
Jan      $2,124  $833      $1,291     $98,709
Feb      $2,124  $822      $1,302     $97,407
Mar      $2,124  $812      $1,312     $96,095
...      ...     ...       ...        ...

Payments in earlier periods primarily consist of interest repayment, with subsequent payments consisting more of principal repayment.
