Plan the cash gap before taking family-care leave in Korea
When a parent, spouse, child, or another covered family member needs care after an illness, accident, or because of old age, finding time can feel more urgent than reviewing household finances. A leave period can nevertheless remove a large part of one worker's income while medical travel, meals, supplies, and replacement care add new costs. This calculator turns those changes into a calendar-month plan so you can estimate the personal income gap, the household's net cash flow, and the emergency savings needed before submitting an application.
The tool is designed for employees covered by the Korean framework. It does not decide whether an employer must approve a particular request, and it does not assume an automatic statutory paid-leave amount. Enter only take-home pay, employer benefits, or other income that you have actually confirmed. That conservative boundary prevents an unverified benefit from making a fragile budget look safer than it is.
Income gap
Compare normal take-home pay with confirmed income during each leave month.
Emergency fund
Find the deepest cumulative cash deficit and the first month savings fall below zero.
Alternative plans
Compare leave, reduced working hours, and normal work with private care on one timeline.
Keep “confirmed monthly income during leave” at KRW 0 unless a work rule, collective agreement, employer welfare program, or another source confirms a payment. The calculator does not invent a paid amount.
The statutory checkpoints used in this calculator
The legal references were checked on August 25, 2026. The principal provisions are Articles 22-2 and 22-3 of Korea's Equal Employment Opportunity and Work-Family Balance Assistance Act and Articles 16-2 through 16-4 of its Enforcement Decree. The Act view used here is effective August 20, 2026. The current August 20 Enforcement Decree text and its scheduled September 18, 2026 consolidation were also reviewed.
Korean family-care leave statutory checkpoints| Checkpoint | Baseline | How the calculator uses it |
|---|
| Annual family-care leave | Up to 90 days | Subtracts days already entered and shows any excess. |
| One leave segment | At least 30 days | Counts both the start and end date as calendar days. |
| Family-care vacation | Up to 10 days | Treats vacation days as part of the same 90-day annual total. |
| Ordinary application timing | 30 days before start | Shows a confirmation signal when the entered lead time is shorter. |
| Continuous service checkpoint | 6 months | Flags shorter service for an employer-specific exception review. |
| Reduced-hours alternative | 15–30 hours a week | Provides context only; you enter the income confirmed by your employer. |
Covered family members include grandparents, parents, a spouse, a spouse's parents, children, and grandchildren. The listed care grounds are illness, accident, and old age. The Enforcement Decree contains circumstances in which an employer may not have to grant the requested leave, including service shorter than six months and other fact-specific situations. A green checkpoint therefore means only that the number entered meets the baseline used by this tool; it is not an approval decision or legal opinion.
How to use the calculator
- Enter the application, start, and end dates. The end date is included. The result shows the planned days, the ordinary 30-day filing lead time, and the 30-day segment checkpoint.
- Add all family-care days already used this year. Include day-unit family-care vacation as well as previous leave. This makes the remaining 90-day signal useful.
- Use one consistent income basis. Take-home amounts are usually easiest for a living-cost plan. Do not mix a gross salary for one scenario with take-home income for another.
- Separate essential expenses from leave-driven changes. Rent, debt payments, basic food, and recurring bills belong in essential living costs. Medical travel, supplies, and additional meals belong in the care-cost field.
- Enter confirmed payroll deductions separately. Insurance and tax treatment can depend on employer payroll practice and individual facts. Use only an amount and timing that payroll has confirmed.
- Compare alternatives with matching assumptions. Ask for an estimated take-home amount under reduced hours and obtain a private-care quote covering the same dates.
- Review the monthly table, not only the headline. A return-month payroll cutoff, one-time transition cost, or bonus date can create a temporary shortfall even if the total plan looks manageable.
How monthly proration works
Actual calendar days are used
The calculator divides a partial month by that month's actual number of days. If leave begins on October 16, the normal-work portion and leave portion are each measured against 31 days. The expected return date is the day after the leave end date. When leave ends on the last day of a month, a separate return-month row is created so the return income rate and one-time return cost are not lost.
Expected personal income
= normal take-home pay × pre-leave share
+ confirmed leave income × leave share
+ normal take-home pay × return-month rate × post-leave share
Fixed and leave-variable costs are treated differently
Essential living costs are charged in full for every calendar month shown because rent and other fixed commitments do not disappear when leave starts mid-month. Additional care cost, confirmed insurance or tax payments, and saved work costs are prorated by the leave-day share. If saved work costs exceed the other variable leave costs, that component stops at zero rather than becoming fictional income.
Monthly net cash flow = personal income + other household income + confirmed bonus − total expenses
Emergency fund required = amount needed to offset the lowest cumulative net cash flow
Additional savings needed = max(0, required fund − current savings)
Prepare reliable income and cost inputs
Income evidence
- Average recent payslips after removing unusual one-time items.
- Written work rules or a collective agreement covering pay and allowances during leave.
- A payroll estimate showing the return-month cutoff and proration method.
- Separate confirmation of any employer welfare payment or public assistance.
- The payment date and leave treatment of an expected bonus.
Expense evidence
- Bank transfers and card statements for non-negotiable monthly commitments.
- Transport, meal, hygiene supply, equipment, and treatment-support estimates.
- Work travel and meal costs that genuinely stop during leave.
- Insurance or tax notices that payroll says must be paid separately.
- Quotes for private care, including overtime, transport, and cancellation charges.
Worked planning examples
Example 1: Ninety days after a parent's operation
Suppose the employee normally takes home KRW 3 million a month, has no confirmed income during leave, and another household member brings in KRW 2 million. Essential living costs are KRW 3.2 million, additional care costs are KRW 500,000, and commuting and work meals fall by KRW 250,000. The monthly rows show how much of the personal income disappears, how the household deficit accumulates, and whether current emergency savings cover the plan through the return date.
This is still a planning estimate. Before relying on it, replace the defaults with payroll-confirmed insurance treatment, the actual return-month pay rate, and any one-time equipment or transport expense.
Example 2: Leave versus reduced working hours
If full-day care is not required every day, request a written reduced-hours pay estimate and enter the care needed during the remaining hours. Korean law describes a family-care reduced-hours framework with 15 to 30 working hours a week after reduction and a base maximum period, but actual eligibility, duration, schedule, and pay require employer confirmation. The comparison shows the emergency-fund effect without claiming that the employer has approved the schedule.
Example 3: Vacation days already used
If seven family-care vacation days were already used, enter seven in the annual-used field. A new 90-day leave plan then shows 83 days remaining before the plan and seven days over the entered annual total. Compare that signal with your attendance record and application history because this calculator cannot see the employer's official balance.
Interpreting the three scenarios
The family-care leave scenario uses confirmed leave income, leave-related care costs, saved work costs, and a return-month transition cost. The reduced-hours scenario uses the take-home income and care cost you enter for the planned care period. The normal-work scenario retains normal income and applies the private-care quote during that period. All three use the same essential living costs, other household income, date range, and initial care cost.
“Lowest reserve” is not a recommendation
The highlighted option needs the smallest emergency fund under the numbers entered. It does not evaluate the family member's medical needs, emotional load, quality of care, travel burden, job sustainability, or employer approval. Use it as a cash-flow comparison, then make the care and employment decision separately.
Documents to check before applying
- Work rules and collective agreements: paid status, bonuses, allowances, welfare points, and any notice form.
- Payslips and payroll cutoffs: normal take-home income, return-month proration, and delayed deductions.
- Insurance information: payment, postponement, and settlement timing during or after leave.
- Care evidence: the family relationship and documents the employer requests for illness, accident, or old age.
- Annual attendance records: every family-care leave and family-care vacation day used in the same year.
- Alternative quotes: reduced-hours schedule and pay, or a private-care contract covering matching dates.
Frequently asked questions
Does Korean family-care leave automatically provide paid income?＋
This calculator makes no automatic paid-income assumption. Enter a payment only when your employer rules, collective agreement, welfare program, or another confirmed source supports it.
Are the 10 family-care vacation days separate from the 90 leave days?＋
The ordinary family-care vacation allowance is up to 10 days, but those days count within the annual 90-day family-care leave total. Include days already used in the input.
What if I cannot apply 30 days before the start date?＋
The Enforcement Decree sets the ordinary 30-day filing schedule and also addresses late applications. The tool only shows a confirmation signal, so contact the employer immediately about the submission and possible start date.
Does service shorter than six months mean an automatic rejection?＋
The Enforcement Decree contains an employer exception related to continuous service shorter than six months, but facts and current rules must be checked. The calculator does not issue a rejection decision.
Can I enter gross salary instead of take-home income?＋
You can model a consistent gross basis, but take-home figures are clearer for a living-cost budget. Never mix gross income in one scenario with net income in another.
Is the monthly result an exact payroll forecast?＋
No. It prorates the values you enter by calendar days. Employer payroll periods, deductions, bonuses, insurance, and tax treatment may produce a different actual payment.
Tips, limitations, and safety margins
Make the plan more resilient
- Run a second case with the lowest confirmed income and the highest plausible care cost.
- Lower the return-month rate if payroll closes before the actual return date.
- Compare 30-, 60-, and 90-day plans when the medical schedule is uncertain.
- Review payment dates within each month because a monthly total cannot show daily liquidity.
Decisions the tool cannot make
- It does not confirm employer approval or the application of a Decree exception.
- It does not decide whether adverse treatment or a dispute is unlawful.
- It does not calculate final social-insurance, tax, or public-benefit liability.
- It does not diagnose a family member or determine the required level of care.
Official references and verification scope
Article 22-2 of the Act supports the covered family relationships, care grounds, 90-day annual leave framework, 30-day minimum segment, and the treatment of family-care vacation within the annual total. Article 22-3 provides the family-care reduced-hours framework. Enforcement Decree Articles 16-2 through 16-4 address application timing, supporting information, employer exceptions, and withdrawal. Always review the current Korean text and ask the employer or a qualified labor professional about your facts.
Check how long your household can absorb the income gap
Gather payslips, essential monthly bills, and care quotes, then replace the defaults above. Share the monthly result with your family and employer, confirm every uncertain payment, and turn the remaining gap into a savings or expense-adjustment plan before filing.
