See principal and interest separately

The schedule shows how each payment is split between principal and interest. Interest usually takes a larger share while the remaining principal is high. As the principal falls, more of each payment goes toward principal.

Enter the terms from your own contract

Enter the loan amount, annual rate, and term from your own CNY loan contract or your financial institution's information. Use the contract to check the repayment method, fees, early repayment terms, and whether the rate can change.

Use the schedule to compare terms

Review each payment, total interest, and remaining principal together to compare different rates or terms. Check the financial institution's latest information before changing the contract or making a repayment.

Extra payment and refinance comparison

Compare a remaining loan, recurring extra payments, and a hypothetical refinance using rates and costs you enter.

Assumptions, worked example, and source

Rates are user-entered; no current lender rate or product recommendation is supplied. Most countries use annual rate ÷ 12. Canada uses nominal semi-annual compounding converted to a monthly rate.
Extra payment is applied after scheduled interest with no prepayment charge. Enter any early-repayment charge in refinance costs and confirm overpayment limits with the lender.
Refinance break-even accumulates monthly payment differences until they recover upfront costs. It is a cash-flow measure, not an equity, tax, opportunity-cost, or approval analysis.
The default worked example compares one remaining balance over its remaining term. Replace every assumption with the current statement and a formal refinance quote.

Frequently asked questions

Why does the split between principal and interest keep changing?

Interest is calculated from the remaining principal each month. The balance is higher near the start of a loan, so interest takes a larger share. The principal share grows as the balance falls.

What formula calculates the payment?

The calculator uses the standard formula M = P × [r(1+r)^n] / [(1+r)^n − 1]. P is the principal, r is the monthly rate, and n is the total number of payments.

How much can a shorter term reduce total interest?

A shorter term raises each payment but reduces the time that interest accrues, so total interest falls. Compare the exact difference with the terms in your own contract.

What happens if I repay extra principal during the loan?

If the extra payment reduces principal, the balance used for later interest calculations also falls. Check the contract and the financial institution's information for how it is applied.

Do the results include taxes and insurance?

No. This calculator covers principal and interest only. Check the contract to see whether the actual payment includes other costs.
