Installment conversion is a service that changes the repayment method after a lump-sum purchase. With revolving credit, you agree to carry part of the balance over to the next month. When choosing, check the total fees and the conditions for completing repayment.\n\nThe revolving credit calculations below are examples provided in a KB Kookmin Card disclosure reviewed on February 23, 2026.\n\n## Comparison of Installment Plans, Installment Conversion, and Revolving Credit\n\nThe key difference among the three methods is how the repayment schedule is set. Installment plans and installment conversion divide the principal over the selected period. Revolving credit repays an amount based on the payment ratio and carries over the remaining principal.\n\n| Comparison item | Card installment plan | Post-purchase installment conversion | Revolving credit |\n| --- | --- | --- | --- |\n| When selected | When purchasing a product or service | After a lump-sum purchase | Applied to eligible charges after enrollment |\n| Unit of application | Transaction made using an installment plan | Eligible lump-sum transaction | Eligible charges specified in the agreement |\n| Repayment method | Repaid in installments over the selected period | Repaid in installments over the converted period | Balance carried over after repayment based on the agreed payment ratio |\n| End of repayment | Ends after normal payment through the specified installment | Ends after normal payment through the specified installment | Varies depending on the balance, additional spending, and payment ratio |\n| Cost | Interest-bearing or conditionally interest-free | Individual fees, subject to separate waiver conditions | Fees on the principal carried over |\n| Main items to check | Interest-free eligibility and number of installments | Application deadline and total fees | Minimum payment and carried-over balance |\n\nHere, installment conversion is a service that converts a lump-sum charge afterward. Do not confuse it with splitting a payment among several cards at a store. The official name for revolving credit is an agreement to carry over part of the payment amount. You can also check the basic structure in the [Financial Services Commission's comparison of revolving credit and installment plans](https://www.fsc.go.kr/no040101?cnId=2396\u0026curPage=142\u0026pastPage=142\u0026srchKey=\u0026srchText=).\n\n## How Do Fees and Interest-Free Benefits Differ?\n\nYou cannot conclude that installment conversion is always more expensive than an installment plan. The applicable rate varies depending on the user, the usage period, and other factors. Compare the total fees under the same repayment amount and period.\n\nAn installment plan divides the principal and adds fees to the billed amount. The available periods vary by card issuer and merchant. The same maximum installment period does not apply to every card.\n\n| Displayed condition | Meaning | What to check |\n| --- | --- | --- |\n| Interest-free installments | Installment fees are waived if the conditions are met | Eligible cards, merchants, number of months, and promotion period |\n| Partially interest-free installments | Fees are waived only for certain installments | Installments you must pay fees on and total fees |\n| Conversion of a lump-sum payment to installments | Payment schedule changed after purchase | Whether the interest-free promotion available at purchase applies |\n| Annual fee rate | Cost benchmark shown as an annual percentage | Amount billed based on the actual balance and usage period |\n\nAn interest-free benefit offered at the time of purchase does not automatically apply to a later conversion. However, installment conversion may have separate fee waiver conditions. The [Samsung Card installment conversion guide](https://www.samsungcard.com/personal/payment/installment/UHPPPA0500M0.jsp) provides conditions for waiving fees on certain installments. Check the conditions that apply to you on the application screen.\n\nWhether a transaction is interest-free and whether it earns points are also separate matters. The [Shinhan Card points guide](https://www.shinhancard.com/pconts/html/benefit/my/point/pointExplain/CONFM50047/CONFM50047R01.html) states that interest-free installments are excluded from point accrual. Check your card's product description for the criteria used to count spending toward the previous month's performance requirement.\n\n## Revolving Credit Calculation Example\n\nThe actual amount debited under revolving credit is not simply the eligible principal multiplied by the payment ratio. This is because fees are added separately. You may also have to pay billed amounts that are not eligible for revolving credit.\n\nThe KB Kookmin Card disclosure calculates the amount under the following conditions. The annual rate of 17% is for illustration. Do not interpret it as the rate currently applied to you.\n\n| Calculation condition | Disclosure example |\n| --- | ---: |\n| Principal carried over from the previous month | KRW 500,000 |\n| New eligible spending for the current month | KRW 300,000 |\n| Agreed payment ratio | 50% |\n| Annual fee rate | 17% |\n| Carryover period | 30 days |\n| Charges not eligible for revolving credit | KRW 100,000 |\n\n- Eligible principal repaid this month: (KRW 500,000 + KRW 300,000) × 50% = KRW 400,000\n- Carryover fee: KRW 500,000 × annual rate of 17% × 30 days ÷ 365 days = KRW 6,986 according to the disclosure\n- Total payment this month: KRW 400,000 + KRW 6,986 + KRW 100,000 = KRW 506,986\n- Eligible principal remaining after payment under the agreement: KRW 400,000\n\nIn this example, 50% does not mean paying only half of the total billed amount. KRW 400,000 in principal will still remain next month. The calculation conditions and amounts are based on the [KB Kookmin Card revolving credit disclosure](https://card.kbcard.com/FNC/DVIEW/HFCMCXPRIFIC0009?mainCC=d).\n\n## Selection Criteria by Situation\n\nYour selection should be based on a repayment schedule you can manage, rather than how much this month's bill will decrease. Dividing money you have already spent leaves payment obligations for the following months. Consider future card charges as well.\n\n| Current situation | Method to consider | Decision criteria |\n| --- | --- | --- |\n| You have not yet made the purchase and plan to repay in installments | Choose installments at purchase | Interest-free conditions and an affordable monthly payment |\n| You made a lump-sum purchase and can set a repayment period | Check whether installment conversion is available | Eligible transaction, application deadline, and total fees |\n| You temporarily lack funds for payment | Ask the card issuer about available payment methods | Effective date and funds for later repayment |\n| You already have a revolving credit balance | Consider reducing additional carryovers and repaying early | New spending, remaining principal, and cost of full repayment |\n| You may also struggle to obtain the required payment amount next month | Request repayment counseling from the card issuer | Available adjustments other than repeated carryovers |\n\nRevolving credit can help address a short-term shortage of funds if payments are made according to the terms. However, the carried-over balance may grow if new card charges are also added. The Financial Supervisory Service warns that long-term use may affect creditworthiness. Related information appears in the [consumer alert dated December 12, 2023](https://www.samsungfire.co.kr/download/consumer/ca_d43.pdf).\n\n## What to Check Before Applying for Installment Conversion\n\nFor installment conversion, first check the eligible transaction and application deadline. Not every lump-sum transaction can be converted. Check whether the transaction can be converted in the card issuer's app or on its website.\n\n1. Find the lump-sum transaction you want to convert in the card issuer's app.\n2. Check whether it is eligible for installment conversion and confirm the application deadline.\n3. Compare the monthly billed amount and total fees for each available period.\n4. Check the first payment date and whether interest-free or partial fee waivers apply.\n5. After applying, check the revised scheduled payment amount and the completed processing record.\n\nThe [BC Card installment conversion guide](https://bccard.com/app/card/view/common/ContentsLinkActn.do?pgm_id=ind0425) specifies application restrictions by transaction. If the deadline has passed, ask the card issuer whether conversion is still available. Simply attempting to apply does not change your existing payment obligation.\n\n## Effects on Credit Scores and Delinquency\n\nApplying for a service and actually becoming delinquent should be assessed separately. You cannot conclude that merely applying for an installment plan or installment conversion will reduce your score by a fixed amount. There is also no basis for stating a single figure for changes in credit scores.\n\nRevolving credit is likewise not a safeguard that guarantees protection of your credit score. The Financial Supervisory Service advises that long-term use may adversely affect creditworthiness. Check the following items separately.\n\n- Installment plans and installment conversion: Check whether you paid the amount billed on the scheduled payment date\n- Revolving credit: Check whether you paid at least the minimum payment shown on the statement\n- Items common to all methods: Check the remaining debt and future card charges\n\nPaying less than the minimum payment under revolving credit may result in delinquency. Simply applying for the service does not prevent delinquency. Check the actual payment result after the debit is processed.\n\n## Common Mistakes: Changing the Payment Ratio and Cancellation\n\nChanging the revolving credit payment ratio to 100% does not cancel the agreement. KB Kookmin Card states that part of the balance may be carried over if the account has insufficient funds. To stop automatic carryovers, check the status of the agreement separately.\n\n| Common misconception | What to check in practice |\n| --- | --- |\n| Revolving credit ends when the payment ratio is 100% | Check separately whether the agreement has been canceled |\n| Adding more money to the account repays the entire balance | Check the amount actually debited and whether a separate immediate payment is needed |\n| Cancellation eliminates the remaining principal | The obligation to pay the remaining principal and fees continues |\n| The same terms remain available until the agreement period ends | Check whether renewal is available and the repayment conditions at expiration |\n\nBefore cancellation, check when the remaining balance will be billed. The Samsung Card terms allow the full amount used to be billed upon cancellation. Therefore, do not rush to cancel without checking your repayment funds. The basis is [Article 38 of the Samsung Card Personal Membership Terms](https://www.samsungcard.com/personal/customer-service/conditions/personal/UHPPCC0379M0.jsp).\n\n## Difference Between Post-Purchase Installment Conversion and the Right to Assert Defenses\n\nThe right to assert defenses against installment payments does not apply to post-purchase installment conversion of a lump-sum payment. This right allows you to refuse payment of the remaining installments under certain conditions. It may apply when a product or service is not provided as promised.\n\nThe BC Card \"Installment Conversion\" guide describes post-purchase converted transactions as follows.\n\n\u003e They are not eligible for the exercise of the \"right to assert defenses against installment payments\" prescribed by the \"Installment Transactions Act.\"\n\nEven if you choose installments at the time of purchase, not every transaction is protected. Requirements concerning the amount, number of installments, purpose of the transaction, and other factors must be met. The [Shinhan Card Personal Membership Terms](https://www.shinhancard.com/pconts/html/helpdesk/terms/terms56/1238377_1133.html) specify the applicable conditions and exclusions.\n\nYou should therefore also check consumer protection conditions before payment. Changing only the payment schedule is separate from protection under the purchase contract. If a dispute has already arisen, ask the card issuer about the applicable objection procedure.\n\n## How Do Card Limits and Debit Cards Differ?\n\nEven if you choose installments, the card's available credit is used by the full purchase amount. It is not a structure in which only the amount billed each month is deducted from the limit. This standard can also be checked in [KB Financial Group's explanation of card limits](https://kbthink.com/card/limit.html).\n\nOrdinary debit card transactions that are debited immediately are not eligible for installment payments. Amounts already debited also cannot be converted like credit card installment conversion. If the card has a separate credit feature, check the terms of that service. The [Hyundai Card hybrid guide](https://www.hyundaicard.com/upload/card/20260428_%ED%95%98%EC%9D%B4%EB%B8%8C%EB%A6%AC%EB%93%9C%20%EC%BA%90%EC%8B%9C%EB%B0%B1%ED%98%95.pdf) also states that installment payments are unavailable.","content_html":"\u003cp\u003eCard installment plans let you decide at the time of purchase to repay the amount in installments.

A post-purchase installment plan changes the payment method for a purchase already made as a single payment. Interest-free benefits and the right to assert a defense for installment purchases also do not apply in the same way."},{"question":"Are fees for post-purchase installment plans always higher than installment purchase fees?","answer":"They are not necessarily always higher. They vary depending on the rate applied to each person and the payment period. Compare the total fees based on the same amount and period."},{"question":"Are interest-free benefits available for post-purchase installment plans too?","answer":"The interest-free benefit offered at the time of purchase does not automatically apply to a post-purchase conversion. Separate fee waiver conditions may be available. Check the application screen for the conditions that apply to you."},{"question":"If my revolving payment rate is 50%, do I pay only half of the billed amount?","answer":"The 50% rate applies to the principal balance eligible for revolving payments. Fees and billed amounts not eligible for revolving payments may be added separately. Check your statement for the actual amount to be withdrawn."},{"question":"Can applying for revolving payments prevent late payment?","answer":"You must pay the minimum payment amount specified in the agreement. Paying less than the minimum payment amount may result in late payment. Simply applying does not guarantee that late payment will be prevented."},{"question":"Will applying for a post-purchase installment plan lower my credit score?","answer":"You cannot assume that applying alone will lower your score by a set number of points. Changes in your score depend on your credit information and the assessment results. Manage both your scheduled payment dates and remaining debt."},{"question":"If I change my revolving payment rate to 100%, is the agreement canceled?","answer":"Changing the payment rate and canceling the agreement are separate matters. If the agreement remains active, a balance may be carried over when there are insufficient funds in your account. Check the status of the agreement separately."},{"question":"When do I pay the remaining balance if I cancel revolving payments?","answer":"The remaining balance may be billed in full when you cancel. Your obligation to pay the remaining principal and fees does not disappear. Before canceling, ask your card issuer when the balance will be billed."},{"question":"If I convert a single payment to a post-purchase installment plan, do I gain the right to assert a defense for installment purchases?","answer":"The right to assert a defense for installment purchases does not apply when a single payment is later converted to a post-purchase installment plan. You must distinguish between an installment agreement made at the time of purchase and a later change to the payment method. If there is a dispute, ask your card issuer about the available objection procedures."},{"question":"If I make an installment purchase, is only the monthly payment deducted from my card limit?","answer":"Your available credit is reduced by the full purchase amount. It is not reduced only by the monthly billed amount. Check your remaining available credit before making a purchase."},{"question":"Can debit cards also be used for installment purchases or post-purchase installment plans?","answer":"These do not apply to standard debit card transactions in which funds are withdrawn immediately. For products with a separate credit feature, you must check the terms for that feature."},{"question":"Do interest-free installment purchases still earn points and count toward the previous month's spending requirement?","answer":"Point accrual and whether purchases count toward the previous month's spending requirement are governed by the respective product terms. Some cards exclude interest-free installment purchases from point accrual. Check the product guide for your card for each of these criteria separately."}],"sources":[{"url":"https://www.fsc.go.kr/no040101?cnId=2396\u0026curPage=142\u0026pastPage=142\u0026srchKey=\u0026srchText=","title":"Financial Services Commission Card News: Comparison
