❓ Frequently Asked Questions
What is the difference between Equal Payment and Equal Principal?
Equal Payment (等额本息) keeps your monthly payment the same throughout the loan. Equal Principal (等额本金) has decreasing payments because you pay the same principal each month plus decreasing interest. Equal Principal results in less total interest paid.
How is the monthly payment calculated?
For Equal Payment: M = P × r(1+r)^n / ((1+r)^n - 1), where P is the principal, r is the monthly rate, and n is total months. For Equal Principal: monthly principal = P/n, and interest decreases each month.
What is an amortization schedule?
An amortization schedule is a detailed table showing each monthly payment broken down into principal and interest portions, along with the remaining loan balance after each payment.
How much can I save with early repayment?
The savings depend on your extra payment amount and when you start. Even small extra payments can significantly reduce your total interest and shorten your loan term. Use our Early Repayment calculator to see exact savings.
Does this calculator account for taxes and insurance?
This calculator focuses on principal and interest payments only. Property taxes, homeowner's insurance, and PMI are not included. Your actual monthly housing cost will be higher than the calculated payment.
