VAT Calculator

Calculate supply price, VAT, and total (10% rate)

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

  1. Choose the calculation mode (from supply price or from total).
  2. Enter the amount and the other two values are calculated automatically.
  3. 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.
