This app can calculate 20% and 5% VAT. The feature of this app is that a calculation frame is set up separately for each tax rate. For this purpose, you can check the tax-included amount of 20% and 5% at the same time without changing the screen or erasing the entered value. And the total value of each tax-included amount is calculated automatically, so you can check the total amount without any hassle. This is useful when you need to calculate VAT, such as when shopping, selling products, or estimating. You can enter formulas such as 100 + 300 and 100x3, so you can calculate the tax-inclusive amount for multiple products at once. In addition to tax-included amount, the tax-excluded amount and tax amount are displayed separately. Once set, fractions can be rounded down, rounded up or rounded off. You can calculate discounts. It is easy to operate because it can be calculated simply by pressing a preset button such as 5%, 10%, 15%, 20%, etc. You can also enter a number and calculate at other percentages. Calculation results are automatically saved in the history and can be checked later.
