Add VAT to a quote’s net amount, or split VAT out of a payment total.
Both languages use KRW and whole-won rounding. This does not calculate tax payable or tax returns.
| Method | Net amount | VAT | Gross total |
|---|---|---|---|
| Nearest (selected) | 100,000 KRW | 10,000 KRW | 110,000 KRW |
| Round down | 100,000 KRW | 10,000 KRW | 110,000 KRW |
| Round up | 100,000 KRW | 10,000 KRW | 110,000 KRW |
VAT = net amount × rate, rounded to whole won.
The default 10% refers to standard Korean VAT. Both language versions use KRW and whole-won rounding. Check your document's rounding rules. This does not calculate tax payable, input credits, or simplified-taxpayer returns. NTS rate information

Choose Net → add VAT. Enter the unit price, quantity and rate to see net amount, VAT and gross total together.
Choose Gross → extract VAT. Select a rounding method; the gross amount stays unchanged while net and VAT are separated.
Paste tab-separated amount and quantity columns for a batch. Discounts apply to each row first; compare row-rounded VAT with a single calculation on the combined amount.
A worked example
The discount applies to unit price × quantity before VAT. This example uses nearest-won rounding.
