KRW
Enter an amount
* Based on Korea's standard VAT rate (10%)
Overview
Calculate Korean VAT at 10%: supply price, VAT amount, and total. When issuing tax invoices or writing quotes, you often need to separate VAT from the supply price or reverse-calculate the supply price from a VAT-inclusive amount. Enter one number and get all three values at once. These results are for reference only; consult a tax professional for actual filings.
Key Features
- Supply price to VAT + total calculation
- Total (VAT-inclusive) to supply price + VAT reverse calculation
- VAT amount input to supply price / total calculation
- Automatic thousands separator formatting
- One-click copy of results
How to Use
- Choose the calculation mode (from supply price or from total).
- Enter the amount and the other two values are calculated automatically.
- Copy the values you need.
Tips
- Korean VAT is fixed at 10%. Supply price x 1.1 = total; total / 1.1 = supply price.
- Tax invoices require the supply price and tax amount down to the won.
- These calculations are for reference only and do not guarantee accuracy for actual tax processing. Consult a tax professional for filings and accounting.
FAQ
- Can I change the VAT rate from 10%?
- This tool is set for the Korean VAT rate of 10%. For other rates, use the percentage calculator.
- Can I calculate for tax-exempt items?
- Tax-exempt items have no VAT, so this tool does not apply. Whether an item is exempt depends on the product category -- refer to the National Tax Service for details.
- How are sub-won decimals handled?
- Amounts below 1 won are rounded. In actual tax practice, sub-won amounts are truncated or rounded as well, but confirm the exact rule with a tax professional.
