📘 Example Calculation
Let’s say you want to buy a house with the following details:
- Loan Amount: $400,000
- Interest Rate: 6%
- Loan Term: 30 years
After calculation:
- Monthly repayment: ≈ $2,398
- Total interest paid: ≈ $463,000
- Total repayment: ≈ $863,000
💡 Insight: If you shorten your term to 20 years, your monthly payment increases slightly, but your interest drops by over $180,000!
🧠 How the Calculator Works
This calculator uses a loan amortization formula, which divides your payments into principal (loan balance) and interest portions.
At the start of the loan, most of your payment goes toward interest. Over time, as your balance decreases, a larger portion of each payment goes toward the principal.
By adjusting inputs such as loan amount, rate, or term, you can instantly see how these factors affect your repayment plan.
