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.

Read savings in today’s purchasing power
A maturity balance is only one view; tax, fees, inflation and early exit can change what the money is worth to you.
Safe next action: Open the local savings purchasing-power workspace. Open related page
Audience, steps, example, risks and evidence
Understand the reasoning
Read savings in three passes: money contributed, interest left after assumed costs, and purchasing power at the end. Contributions are your own money, not earnings. Next test an early withdrawal separately, because the advertised maturity rate may not survive early exit. Inflation is an assumption here; the result is not a statement about future prices or your tax treatment.
Worked learning example
With no extra contributions, an invented ₩1,000,000 becomes ₩1,040,000 after one year. At assumed inflation of 4%, that equals ₩1,000,000 in starting-year purchasing power, before tax and fees.
Check your understanding
Does a larger account balance always buy more than the starting balance?
Show answer and explanation
No. Compare the balance after costs with inflation-adjusted purchasing power and keep contributed money separate from earnings.
Common mistake: A tax percentage entered for practice does not establish the rate that applies to a real account.
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
- gross interest
- tax assumption
- fees
- real purchasing power
Steps
- Enter contributions, time and the stated rate.
- Add explicit tax, fee and inflation assumptions.
- Compare maturity with an early-exit scenario before choosing the next action.
Worked example
With no extra contributions, an invented ₩1,000,000 becomes ₩1,040,000 after one year. At assumed inflation of 4%, that equals ₩1,000,000 in starting-year purchasing power, before tax and fees.
Risks and limits
- A tax percentage entered for practice does not establish the rate that applies to a real account.
- Actual provider terms and future outcomes can differ.
- A missing fee, tax or timing assumption can materially change the result.

Separate an investment illustration from a forecast
Use return, fee, inflation and downside assumptions to see sensitivity, never to claim what the market will deliver.
Safe next action: Open the local investment cost and retirement illustration. Open related page
Audience, steps, example, risks and evidence
Understand the reasoning
Begin with contributions and the date money will be needed. Change return, fees and inflation independently to learn which assumption drives the result. Then try a negative return and a shorter access horizon. This deterministic illustration has no probabilities and no sequence of market shocks; it cannot establish suitability, liquidity or the maximum possible loss.
Worked learning example
An invented ₩1,000,000 at +5% ends at ₩1,050,000 after one period before fees. At −20% it ends at ₩800,000. These are two inputs, not probabilities or limits on loss.
Check your understanding
Can the displayed downside be treated as the largest possible loss?
Show answer and explanation
No. It is only the outcome of one chosen assumption; other paths, fees and constraints can produce a worse result.
Common mistake: A smooth annual projection hides the order of gains, losses and withdrawals.
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
- contribution
- return assumption
- fee drag
- downside scenario
Steps
- Choose an amount and time horizon you can explain.
- Enter fees and inflation instead of looking only at headline return.
- Compare baseline and downside illustrations and read the non-guarantee warning.
Worked example
An invented ₩1,000,000 at +5% ends at ₩1,050,000 after one period before fees. At −20% it ends at ₩800,000. These are two inputs, not probabilities or limits on loss.
Risks and limits
- A smooth annual projection hides the order of gains, losses and withdrawals.
- Actual losses can exceed the displayed downside.
- Tax, liquidity and product suitability are not assessed.

Editorial and commercial separation
Advertising, affiliate compensation, bids and conversions cannot change calculator output or organic order.
Safe next action: Treat every future sponsored item as a separately labelled placement. Open related page
Audience, steps, example, risks and evidence
Understand the reasoning
Commercial placement and educational output have separate purposes. A sponsored label must remain visible, and bids or compensation must not become inputs to organic ranking or calculator arithmetic.
Worked learning example
Changing an invented advertiser bid from ₩100 to ₩500 must leave the same loan inputs producing the same repayment result and the same organic order.
Check your understanding
May a higher sponsor payment improve an organic score?
Show answer and explanation
No. Commercial inputs are excluded from that calculation boundary.
Common mistake: Disclosure alone does not excuse secretly changing the organic result for compensation.
Examples are invented educational scenarios, not provider quotes, forecasts or tax rates.
