How to Use the Loan Amortization Calculator
- Enter the loan amount (e.g., $20,000) you plan to borrow.

- Specify the loan term in years (e.g., 5 for a 5-year loan).
- Click Calculate Amortization to view monthly payments, a chart, and an amortization table.
The Logic Behind It
The calculator computes the monthly payment using the formula:
M = P × (r(1 + r)^n) / ((1 + r)^n - 1)
Where:
- M = Monthly Payment
- P = Loan Amount
- r = Monthly Interest Rate (Annual Rate / 12)
- n = Number of Monthly Payments (Loan Term × 12)
The amortization schedule tracks each payment’s principal and interest components, reducing the balance until it reaches zero. The chart shows the loan balance and cumulative interest over time.

- Clarity: See how each payment reduces your loan balance.
- Planning: Budget for loan repayments with accurate monthly costs.
- Insight: Understand the split between principal and interest.
