Estimate installment payments and total fees when each monthly fee is based on the original CNY principal.
Estimated as purchase amount × fee rate for each payment. Enter the rate shown on your bank statement or installment plan.
¥833.33 principal + ¥60.00 fee per payment
Results assume equal principal payments with a fixed fee charged each period. The estimated annualized cost is calculated from cash flows for comparison only. Refer to your card issuer’s agreement and statements for actual amounts, fee timing, and the applicable annual percentage rate.
Overview
Understand what the tool solves, how it works, and the boundaries of its data.
Use this calculator for an installment offer quoted in Chinese yuan (CNY) when the fee for each payment is calculated from the original amount financed. Enter the financed amount, a supported payment count, and the quoted fee rate per payment. It returns principal per payment, fee per payment, payment amount, total fees, total repayment, and an estimated annualized financing cost.
This is an add-on-fee model: principal is split evenly, while every period's fee is calculated against the starting principal. That differs from a reducing-balance loan, a US revolving credit-card APR, and many issuer-specific installment arrangements. The annualized result is derived from the modeled cash flows; it is not a bank quote or a universal APR.
Let P be the financed principal, n the number of payments, and r the fee rate per payment as a decimal.
Principal per payment = P ÷ n
Fee per payment = P × r
Payment per period = (P ÷ n) + (P × r)
Total fees = P × r × n
Total repayment = P + total fees
For example, financing CNY 12,000 over 12 payments at 0.60% per payment gives CNY 1,000 principal plus CNY 72 fee each period: CNY 1,072 per modeled payment. Total fees are CNY 864 and modeled repayment is CNY 12,864. Calculations use the amount and rate you enter; the displayed values are estimates and issuer rounding can change statement amounts.
The annualized cost estimate solves for the monthly rate that makes the present value of 12 equal payments of CNY 1,072 equal CNY 12,000, then compounds that monthly rate for 12 months. Under those equal monthly end-of-period cash-flow assumptions, the example is about 13.84% effective annualized. This is not the simple sum of 0.60% × 12, and actual disclosures can use different conventions or payment dates.
Guide
Follow the workflow and verify inputs and outputs with practical examples.
Take the financed amount from the offer, not the card's full statement balance unless that is the amount being financed. The calculator accepts a positive amount up to CNY 100,000,000.
Select one of the available payment counts: 3, 6, 9, 12, 18, 24, or 36. The list is fixed; it does not accept a custom term.
Enter the fee rate for each payment as a percentage. For a quote of 0.60% per payment, enter 0.60. Do not enter 0.006, a total-term fee rate, or an annualized rate in this field.
Read the payment amount alongside total fees and total repayment. The additional annualized figure is a cash-flow comparison estimate, not a rate supplied by your issuer.
Use cases
See how the tool fits into real work and everyday tasks.
If a China-related purchase is offered in CNY installments, enter its financed amount and the quoted per-payment fee. Compare the resulting payment with the amount your budget can handle, then check the total fee you would pay over the term.
Run each term using the rate actually quoted for that term. Do not reuse one rate if the offer lists different rates by term. A longer term changes both the payment schedule and total fee under this fixed-fee model.
For a CNY offer from a Mainland China issuer, use the quoted fee-per-payment input only if that is how the offer defines its rate. Compare the estimate with the issuer's disclosed annualized rate and calculation method, which may reflect details this simplified schedule does not model.
Q&A
Find concise answers to common questions and confusing cases.
Enter 0.60. The field is a percentage and the calculation converts it to 0.006 internally. Entering 0.006 means 0.006%, producing a fee one hundred times smaller.
No. This model expects a fee rate charged each payment against the original CNY principal. A revolving APR or disclosed annualized financing rate uses a different basis and cannot be substituted to reconstruct the installment schedule.
The calculator solves an internal monthly rate from the modeled equal payments and original principal, then compounds it over 12 months. Simply multiplying the quoted add-on rate by 12 does not account for principal being repaid over time and is not the same cash-flow calculation.
The estimate assumes equal principal portions and a fixed fee based on the starting principal. An issuer may use different rounding, payment dates, fee timing, extra charges, or a different principal and interest method. The issuer's contract and statement determine the amount due.
Notes
Review scope, result limitations, and important precautions before use.
This calculator models fixed fees on the original principal, equal principal portions, and regular monthly payments for its annualized cash-flow estimate. It does not model upfront fees, variable or tiered rates, a reducing balance, irregular payment dates, taxes, promotions, late charges, or early settlement treatment. A zero entered fee only produces zero modeled fees; it does not establish that an offer has no other costs.
For a Mainland China credit-card installment offer, the State Council-hosted 2022 regulatory notice describes disclosure of installment charges, annualized rates, and the calculation method on the agreement and service page. That is jurisdiction-specific context, not a statement of US law or a substitute for your issuer's current terms. Check the offer's currency, rate basis, total charges, payment schedule, early repayment terms, and disclosed annualized cost directly with the issuer. This estimate does not approve an application or provide individualized financial advice.
