How to Use the Loan Calculator

1. Enter your loan amount, annual interest rate, and select the loan term in years.
2. Choose a repayment method: Equal Installment (fixed monthly payments) or Equal Principal (decreasing monthly payments).
3. Review the monthly payment, total payment, and total interest. Use the amortization schedule to see year-by-year breakdown and try the early repayment calculator to see how extra payments save interest.

Frequently Asked Questions

What is the difference between Equal Installment and Equal Principal?

<strong>Equal Installment (等额本息)</strong> keeps your monthly payment constant throughout the loan term — you pay more interest early and less principal. <strong>Equal Principal (等额本金)</strong> pays the same principal each month, so interest decreases over time and monthly payments gradually reduce. Equal Principal saves more total interest but has higher initial payments.
