Your quote, your calculation

Direction: you give USD → receive KRW. Use the actual rate offered for your cash or transfer conditions. This page does not obtain a provider quote or perform an exchange.

Guidance opens a new tab, keeps your entries here and carries no entered amounts or quotes.

Technical ranges: USD 0.01–1,000,000.00 (2 decimals); rate 0.000001–99,999.999999 KRW per USD (6 decimals); separate fee 0–999,999,999 whole KRW. Correctly grouped commas are accepted. These are input limits, not transaction limits.

Quote A · enter what you were actually offered
Quote B · optional comparison

The offered rate may already include its spread. Do not deduct it twice. Enter only a fee separately quoted in KRW. Blank stays unknown; 0 is an explicit entry, not a claim about a provider.

Check cash/transfer type, note denominations or condition where relevant, included charges and quote timing. Any amount, rate or fee edit resets this check. This tool does not verify or recommend a provider.

Optional: dated ECB market reference

Information only, not a cash buying/selling quote or live bank rate. UseKorea derives KRW per USD from the same date’s ECB EUR/USD and EUR/KRW observations. It never fills in your rates or changes the plans above.

Not loaded. Manual quote planning works without this reference.

Daily publication normally excludes weekends and TARGET closing days. A prior observation date is not automatically a failure. Values older than 7 calendar days are withheld by this service’s conservative policy. Only a fixed same-origin reference request is sent when you press the button; none of your quote fields is sent.

📖 Step-by-Step Practical Guide
  • 1
    Step 1Enter the USD amount you give and the actual provider rate in KRW for 1 USD. Choose the quote for selling your USD, not the reverse transaction.
  • 2
    Step 2Enter only a separately quoted KRW fee. Leave it blank if unknown; enter 0 only when no separate fee is explicitly quoted. A spread already in the rate is not deducted again.
  • 3
    Step 3Optionally enter a second quote and confirm matching amount, direction and conditions. The signed difference compares your entries; actual settlement remains unconfirmed.

A useful comparison starts with real quotes

  1. Check the actual rate offered for giving USD and receiving KRW, plus the transaction conditions.
  2. Keep a rate's included spread separate from any fee actually quoted on top.
  3. Compare complete entered plans only after confirming matching conditions. Check the final provider receipt separately.
A quoted rate is different from a market reference

This planner covers one direction: you give USD and receive KRW. Use the actual provider rate for that direction and transaction type. Cash selling and buying rates differ, as can cash and transfer rates. Do not reverse a retail rate by taking its reciprocal or reuse another transaction’s quote.

A provider rate may already include an exchange spread. This planner multiplies your USD amount by that entered rate and subtracts only a separately quoted KRW charge that you enter. It does not deduct an assumed bank, airport or money-changer percentage, infer the spread from a reference rate, or assess any provider.

Intermediate arithmetic uses exact scaled integers. Whole-won results use half-up rounding for display only, including signed differences calculated before display rounding. This is a planning illustration, not a provider’s settlement or cash-denomination rule. Actual spread, tax and final receipt remain unknown.

The optional ECB panel is an informational daily reference, not a cash buying/selling quote or live bank feed. It loads only on your request and never fills in your rates or changes the manual plans. ECB observations are generally published on working days except TARGET closing days; the observation date and collection time have different meanings.

Planning and exchanging are separate

This page makes no payment, exchange, account connection or provider recommendation. A positive quote difference is not verified savings. Use the official guidance links and check the actual quote, conditions and final receipt.

❓ Frequently Asked Questions
Does the planner show a live bank or Myeongdong exchange quote?

No. Enter the actual provider rate for selling your USD and receiving KRW. No bank, airport, neighborhood, promotion or fee percentage is assumed. A market reference is not a retail cash quote.

Should I subtract the spread again from a provider’s offered rate?

No assumed spread is subtracted. A rate offered for the transaction may already include a spread. Enter only a separately quoted whole-KRW fee. Blank means unknown; 0 means you explicitly entered no separate charge. This tool does not verify the quote’s completeness.

What does the A/B difference mean?

It is the signed B-minus-A difference of your entered planned nets, calculated before final display rounding. Both rates, both separate fees and matching amount, direction and conditions must be confirmed. Changing an entry resets that confirmation. It is not verified savings or a provider recommendation.

Is the whole-won plan my final cash payout?

No. Half-up rounding is a display policy for this illustration. Provider rounding, cash denominations, actual spread, tax and final settlement are not confirmed. A missing fee stays unknown; a fee greater than the conversion amount requires checking the quote.

What does the optional ECB reference show?

It shows a dated informational USD/KRW cross-rate calculated by UseKorea from ECB EUR/USD and EUR/KRW observations, with a collection time and source. It is not a transaction rate, never fills in your provider quotes, and is withheld when older than this service’s seven-calendar-day policy. Manual quote planning continues independently.
