Replacing a loan
- Collect written current terms.
- Collect replacement fees.
- Compare the same remaining term.
- Keep the no-saving result.
Life-event checklists
Three decision checklists turn a broad goal into inputs, limits and a safe next action.
Building savings
- Choose the purpose and date.
- Separate rate, tax and fees.
- Test inflation.
- Test early exit.
Planning long-term investing
- Choose contributions and time.
- Add fees and inflation.
- Test a downside.
- Read the non-forecast warning.

Loan example: switching cost is recovered
A positive illustrated saving exists only after every entered switching fee is deducted.
Safe next action: Replace every invented amount with current written terms. Open related page
Audience, steps, example, risks and evidence
Understand the reasoning
Read each total’s included costs before subtraction. This example isolates same-term monetary cost and leaves approval, service quality and future rate changes outside the conclusion.
Worked learning example
₩11,000,000 current remaining total − ₩10,700,000 replacement total − ₩100,000 separately entered fees = ₩200,000 illustrated net saving.
Check your understanding
What if an additional verified ₩250,000 exit charge was omitted?
Show answer and explanation
The revised result would be −₩50,000; the conclusion changes when the missing cost is included.
Common mistake: A positive arithmetic result cannot establish that switching is suitable or available.
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
- Loan example: switching cost is recovered
- assumptions
- limits
Steps
- Write down the values you know.
- Run the matching local calculator.
- Read the assumptions, limits and next action before deciding.
Worked example
₩11,000,000 current remaining total − ₩10,700,000 replacement total − ₩100,000 separately entered fees = ₩200,000 illustrated net saving.
Risks and limits
- A positive arithmetic result cannot establish that switching is suitable or available.
- Actual provider terms and future outcomes can differ.
- A missing fee, tax or timing assumption can materially change the result.

Savings example: nominal and real gain
The same maturity amount can show a smaller gain after the entered tax, fee and inflation assumptions.
Safe next action: Compare at least two inflation assumptions. Open related page
Audience, steps, example, risks and evidence
Understand the reasoning
Separate the nominal after-cost result from the base-date purchasing-power result. This invented example uses no contributions, fees or tax so that only inflation’s effect is visible.
Worked learning example
₩1,000,000 grows to ₩1,050,000 in one year. Dividing by assumed inflation factor 1.02 gives about ₩1,029,412 in starting-year money: approximately ₩29,412 real gain.
Check your understanding
Why is the real gain smaller than the ₩50,000 nominal gain?
Show answer and explanation
The inflation adjustment removes the assumed price increase to express the later balance in starting-date purchasing power.
Common mistake: Adding contributions would require care before labelling the entire balance difference as growth.

Investment example: downside sensitivity
A lower entered return can reduce purchasing power and retirement coverage, but it is not a worst case.
Safe next action: Test a more severe loss before treating the illustration as tolerable. Open related page
Audience, steps, example, risks and evidence
Understand the reasoning
Follow a negative assumption through the amount left rather than stopping at a percentage. Compare with planned spending only when both figures use the same price date.
Worked learning example
A one-period −20% change takes invented ₩1,000,000 to ₩800,000 before costs. At unchanged spending of ₩100,000 per month, simple coverage falls from ten to eight months.
Check your understanding
How many months of simple coverage were lost under these assumptions?
Show answer and explanation
Two months; that calculation does not include later returns, inflation or other income.
Common mistake: The displayed −20% assumption is not a cap on actual loss or a probability statement.
