Understand a loan before replacing it
Compare total remaining cost, replacement cost and switching fees over the same period before treating a lower rate as a saving.
Safe next action: Open the local loan and refinance workspace. Open related page
Audience, steps, example, risks and evidence
Understand the reasoning
Start with the balance still owed, not the original loan amount. Compare keeping the loan with replacing it over the same remaining months. Read the regular payment, final payment and total separately. A lower payment can come from stretching the term rather than reducing the price of borrowing. Keep an unchanged-loan scenario so that doing nothing remains a visible option.
Worked learning example
Invented same-term totals: keep the loan for ₩11,000,000, or replace it for ₩10,700,000 plus a ₩100,000 switching fee. Net reduction is ₩200,000, before any omitted costs.
Check your understanding
What must stay the same before calling the cheaper payment a saving?
Show answer and explanation
Compare the same outstanding principal and remaining term, and include every switching cost. A smaller monthly payment alone is insufficient.
Common mistake: Do not compare a short remaining loan with a longer replacement and describe the payment reduction as a total saving.
Examples are invented educational scenarios, not provider quotes, forecasts or tax rates.
Who this is for
People using the KR educational release who want to understand a money decision before contacting a provider.
Not for
This is not a personal recommendation, provider quote, eligibility decision, tax opinion or legal opinion.
Key concepts
- remaining total cost
- replacement total cost
- switching fee
- net saving
Steps
- Collect the current balance, rate and remaining months.
- Collect the replacement rate and every switching fee in writing.
- Run the same-term comparison and inspect the no-saving result as carefully as a saving result.
Worked example
Invented same-term totals: keep the loan for ₩11,000,000, or replace it for ₩10,700,000 plus a ₩100,000 switching fee. Net reduction is ₩200,000, before any omitted costs.
Risks and limits
- Do not compare a short remaining loan with a longer replacement and describe the payment reduction as a total saving.
- Rates can change and a provider can calculate fees differently.
- Extending the term can lower a payment while increasing total cost.

Check refinance break-even
A replacement only illustrates a saving when reduced remaining cost is greater than switching fees under the same term.
Safe next action: Compare a no-saving outcome before acting. Open related page
Audience, steps, example, risks and evidence
Understand the reasoning
Break-even is a comparison between a cost paid to switch and the reduction that remains afterward. A months-to-recovery shortcut is valid only if the monthly reduction is constant and positive.
Worked learning example
A ₩120,000 fee divided by an unchanged ₩10,000 monthly reduction is 12 months. If the arrangement ends after 6 months, only ₩60,000 has been recovered in this simplified example.
Check your understanding
What happens to recovery time when the monthly reduction is zero?
Show answer and explanation
There is no finite recovery time through monthly reductions; do not divide by zero or label it immediate payback.
Common mistake: The shortcut ignores timing, variable rates and other cash flows; use the full same-term total too.

Not for

Key concepts
- Check refinance break-even
- assumptions
- limits
Steps
- Write down the values you know.
- Run the matching local calculator.
- Read the assumptions, limits and next action before deciding.

Loan example: lower rate but no saving
A lower rate can still produce no net saving when the fee is larger than the reduced interest.
Safe next action: Keep the current arrangement as a comparison option. Open related page
Audience, steps, example, risks and evidence
Understand the reasoning
Use a counterexample to test the lower-rate intuition. A reduced interest amount does not help overall when the cost of obtaining that reduction is greater.
Worked learning example
An invented interest reduction of ₩80,000 with a ₩150,000 switching fee gives ₩80,000 − ₩150,000 = −₩70,000.
Check your understanding
Which option has the lower included total in this example?
Show answer and explanation
Keeping the arrangement costs ₩70,000 less than switching, under the stated equal-term assumptions.
Common mistake: Do not display the ₩80,000 reduction without the larger switching fee beside it.
