What Is the VAT Calculator?

The VAT Calculator lets you quickly add 10% VAT to a net amount, or reverse-calculate the net and VAT from a VAT-included total.

Supported Modes

• From Net: Start with a pre-tax amount, add 10% VAT, and get the total.
• From Total: Start with a VAT-included total, back-calculate the net and VAT (10%).

Example

• Net 10,000 KRW → VAT = 1,000 KRW, Total = 11,000 KRW
• Total 11,000 KRW → Net ≈ 10,000 KRW, VAT = 1,000 KRW

Useful for tax invoices, receipts, and expense processing. Works smoothly on both mobile and desktop.
