💡 Example

🧾 Freelancer invoicing

You agreed on a net amount of ₩500,000 with a client. Use "Supply price → VAT" mode to calculate that the invoice total is ₩550,000 (₩500,000 + ₩50,000 VAT at 10%). Add both figures to your invoice so the client knows the exact payment amount.

🛒 E-commerce pricing

You want to sell a product for ₩33,000 (VAT included). Use "Tax-inclusive total → Supply/VAT split" mode: supply price is ₩30,000, VAT is ₩3,000. Listing the supply price separately is required for business-to-business transactions.

💼 Expense reimbursement

A receipt shows ₩110,000 including VAT. To fill in the accounting form you need the supply price (₩100,000) and VAT (₩10,000) separately. Enter the total and switch to split mode to get both values instantly.

✨ What this calculator does

It models Korea’s 10% standard VAT and a 0% option for cases like exports or exempt treatment—pick what matches your scenario.

Real-world tax rules, rounding for invoices, and credits can be more complex. Do not treat this page as legal or accounting advice.

Highlights

  • Two modes: supply → VAT+total, or total → supply+VAT.

  • Your amounts are not sent to our servers.

Handy for quick quotes, freelance invoices, or classroom examples.

Good use cases

❓ Frequently Asked Questions

Q. Is it really free?
Yes. This VAT calculator is offered at no charge.
Q. Do I need to sign up?
No. Use it directly on this page.
Q. Are my amounts sent to a server?
No. Math runs only in your browser; amounts are not sent to Webooro servers.
Q. What's the difference between 10% and 0%?
10% is the standard taxable rate. 0% applies to exports and exempt goods. Choose the rate that matches your business type.
Q. How are decimals handled?
VAT is rounded to the nearest whole unit. Tax reporting typically uses the same rounding.
Q. Can I use this for tax filing?
This page is for quick reference only. Official filings require correct rules and documentation—consult a tax professional.
Q. Is VAT always 10% in Korea?
The standard rate is 10%. Exports and certain goods are 0% (zero-rated). Some items like agricultural products, education, and medical services are exempt entirely. The exact rate depends on the goods or service type.
Q. Does this work for small-scale taxpayers (간이과세자)?
Small-scale taxpayers (간이과세자) are taxed at a lower effective rate (1.5–4% depending on industry). This calculator uses the standard 10% rate. For simplified taxation, you will need a separate calculation that applies your industry's value-added rate.
