USD To Won Calculator
Planning a trip to South Korea or sending money abroad? Understanding the true exchange cost between the US Dollar (USD) and the South Korean Won (KRW) is essential.
Our USD to Won Calculator helps you estimate:
- KRW amount before fees
- Conversion fee impact
- Bank / ATM / credit card fees
- Total KRW received
- Effective exchange rate
- Total fees in USD
This gives you a realistic view of what you’ll actually receive after charges.
Why Exchange Fees Matter
Most people look only at the exchange rate:
1 USD = 1,320 KRW
But the real amount you receive depends on:
- Conversion fee percentage
- Bank transfer fees
- ATM withdrawal charges
- Credit card foreign transaction fees
Even small percentage fees can significantly reduce your final amount.
How the USD to KRW Calculator Works
The calculator uses this formula:
KRW Before Fees
USD Amount × Exchange Rate
Then subtracts:
- Conversion fee (percentage-based)
- Transaction fee (fixed or percentage-based depending on type)
Result:
Final KRW Amount Received
Step-by-Step: How to Use the Calculator
Step 1: Enter USD Amount
Input the amount you want to convert.
Examples:
- $100
- $1,000
- $5,000
Step 2: Enter Exchange Rate
Enter the current rate:
Example:
1 USD = 1,320.50 KRW
(You can update this manually to match current market rates.)
Step 3: Enter Conversion Fee (%)
Some services charge:
- 0% (mid-market rate)
- 1%–3% (online transfer platforms)
- 3%–5% (currency exchange booths)
The calculator deducts this from the converted KRW amount.
Step 4: Select Transaction Type
Choose one:
Standard Exchange
No additional transaction fee.
Bank Transfer
Flat fee of ₩3,000 deducted.
ATM Withdrawal
Flat fee of ₩5,000 deducted.
Credit Card
3% of converted amount deducted.
Step 5: Click “Calculate”
You’ll instantly see:
✔ USD amount
✔ Exchange rate used
✔ KRW before fees
✔ Conversion fee amount
✔ Transaction fee
✔ Final KRW received
✔ Effective exchange rate
✔ Total fees in USD
Example Calculation
Let’s assume:
- USD Amount: $1,000
- Exchange Rate: 1,320.50
- Conversion Fee: 2%
- Transaction Type: Credit Card
Step 1: Convert to KRW
$1,000 × 1,320.50 = ₩1,320,500
Step 2: Conversion Fee (2%)
₩1,320,500 × 2% = ₩26,410
Step 3: Credit Card Fee (3%)
₩1,320,500 × 3% = ₩39,615
Step 4: Final Amount
₩1,320,500 − ₩26,410 − ₩39,615
= ₩1,254,475
Your effective exchange rate becomes lower than the posted rate.
Understanding Effective Exchange Rate
Effective Rate =
Final KRW Received ÷ USD Amount
This shows the true value you’re getting after fees.
Example:
If you receive ₩1,254,475 from $1,000,
Your effective rate = 1,254.48 instead of 1,320.50
That’s a big difference.

| Method | Typical Cost | Best For |
|---|---|---|
| Standard Exchange | Lowest | Mid-market platforms |
| Bank Transfer | Moderate | Sending large amounts |

Always compare total KRW received — not just the advertised rate.
