任意の金額の消費税や売上税を計算します。
Taxes are an unavoidable part of commerce, but they often make it difficult to know the true price of an item or service. Depending on where you live, the price you see on a shelf might be the 'net' price (before tax) or the 'gross' price (after tax). Businesses also need to quickly 'strip' tax from a total to understand their actual revenue. Our Sales Tax / VAT Calculator is a dual-purpose tool that allows you to either add tax to a base amount or calculate the pre-tax value from a total, providing clarity for both consumers and professionals.
使い方
The tool uses two distinct formulas depending on your selection. If adding tax, it multiplies the base by the rate. If removing tax, it uses the inverse division formula to accurately separate the tax portion from the total.
計算式
Total = Net × (1 + Rate) | Net = Total / (1 + Rate)
Calculation Examples
1. **Adding Tax**: A $100 item with 8.25% sales tax costs **$108.25**.
2. **Removing VAT**: A €120 item with 20% VAT included has a net price of **€100** and a tax amount of **€20**.
Why use this tool in your daily life?
