Korea Energy Voucher Balance and Use Plan Calculator

Plan your Korean energy voucher balance before it expires

An awarded voucher does not make the household heating budget obvious.
Electricity may be billed monthly while kerosene is purchased in a larger delivery, and future charges can differ from last year.
This calculator subtracts already-used funds from a confirmed award and allocates the remainder to dated future bills or card payments.
It is intended for recipients and family members helping them plan out-of-pocket energy costs under Korea’s 2026 program.

The result is a forecast ledger using your records, not a live balance inquiry, benefit award or scheduled provider deduction.
Use a heating-cost tool to estimate charges from consumption if needed, then enter those expected charges here.
All monetary values remain Korean won (KRW), including on this English page.

Check the 2026 program dates

A program year continues into the following spring.
Do not use the previous program’s May 25, 2026 deadline for a 2026 award.
Sources were checked on 2026-09-18; later extensions and administrative changes require another official check.

Both boundary dates are included.
For deductions, confirm the bill issue date and the provider’s deduction application processing.
For card use, confirm that approval/payment completes within the applicable window.
Days remaining are inclusive program calendar days, not a guarantee of merchant opening days or card availability.

Enter the confirmed award, used amount and scope

The official standard annual amounts for households of one, two, three, and four or more people are KRW 295,200, 407,500, 532,700 and 701,300.
Corresponding summer-only amounts are KRW 40,700, 58,800, 75,800 and 102,000.
These are not monthly payments or an automatic eligibility decision.
Enter your confirmed award rather than inferring it from household size; do not combine suspended awards, separate coal-conversion support or additional grants without checking their scope.

Blank means unknown; zero means no usage or charge.
Used funds above the award produce an error rather than a negative balance.
The KRW 10,000,000 limit per money field is a product input limit, not a statutory benefit ceiling.

Bill deduction versus National Happiness Card

Clear summer deduction if you officially requested no summer deduction to retain funds for winter.
Changing the calculator does not submit that request.
After a registered method or source change, confirm its effective date and updated balance before starting a fresh plan.
This model uses one registered winter method per plan; it does not simulate multiple administrative switches.

Allocation formulas and monthly totals

Rows are sorted by date, keeping entry order when dates tie.
A charge outside the period or allowed method receives zero allocation and is entirely out of pocket.
Rows before the reference date remain in the detailed ledger but are excluded from charge and allocation totals to prevent counting already-used funds twice.
An unreflected payment on the reference date itself can be entered as a future charge.

The monthly table combines all charges in the same calendar month, including several fuel purchases and a separate electricity bill.
The first shortfall month means the first positive eligible charge that the balance cannot fully cover.
A month with a non-covered source can have cash costs without being a balance-shortfall month.

Build a plan step by step

1. Follow the official balance instructions, sign in to Bokjiro, and open Welfare Wallet → My Welfare Wallet.
   
2. Enter the confirmed award, reflected usage, plan date, scope and registered winter method.
   
3. Fill missing months for similar recurring charges, then replace assumed month-end dates with actual bill issue or card approval dates.
   
4. Add separate rows for multiple purchases in a month; enter zero or remove rows for months with no charge.
   
5. Review unspent funds, cash requirements and exclusion reasons, save the plan, and check the deduction with the provider.
   

Filling months preserves existing months rather than overwriting them.
A partial month is not automatically prorated: consumption periods and billing periods may differ.
Use the expected billed amount, and edit generated dates near the deadline carefully.
Up to 48 entries are supported; combine entries only when their applicable period and energy classification remain the same.

Worked example: KRW 200,000 across three winter months

With the same balance and only two eligible charges of KRW 50,000 each, KRW 100,000 remains unspent.
That may mean charges are still missing from the plan, not that funds will necessarily remain in the real account.
A permitted card purchase on October 2, 2026 receives no allocation because card use has not started; October 3 can qualify within the remaining balance.
The example is not an average household fuel bill or a recommended spending amount.

Household planning scenarios

Interpretation and limits

A reference date after expiry does not create a new award: days remaining become zero and no out-of-window charge receives allocation.
Missing dates, amounts or confirmation keep results pending.
Do not replace unknown values with zero merely to obtain a total; obtain the relevant records first.
