About TAX calculator - iTaxCalc
“Tax Calculator - TaxCalc" is a calculator that calculates Tax amount. This app calculates the tax amount and other prices using the input value as the base price or tax-inclusive price. It calculates to two decimal places, making it convenient for calculating taxes in currencies such as dollars and euros.
The result price columns (tax-incl., Base price, TAX) are divided into upper and lower with different tax rates, and the two tax rates are calculated together. Each tax rate can be changed by tapping the tax rate column.
After calculation, a frame will be added around the Input value column, and the Input value will be entered in the result price column with a frame, and the tax amount and others will be calculated.
You can add a frame around the Base price column or the tax-incl. column by tapping it.
If there are frames around the both upper and lower base columns, Input value will be in the both base columns, and the tax amount and others will be calculated.
If there is a frame around the tax-incl. column, Input value will be in the tax-incl. column, and the tax amount and others will be calculated. If the Input value is not suitable to the tax-included price (e.g. Input calc. price is 2 and 7.25% tax-incl.), corrected Input value will be in the tax-incl. column with red color. The upper and the lower are calculated using the same Base price.
Tax diff. is the value by subtracting the upper TAX amount from the lower TAX amount.
After calculation, if you tap the Base price column or the tax-incl. column without a frame, the frame will move to the column and other prices will be recalculated.
If you don’t need an input calculation, tap "=" key after entering a price in Input value column.
Instead of tapping "=" key, you can tap a result column.
Tap "Copy" key to copy Input value into clipboard.
Tap Clipboard button to copy a price of each column into clipboard.
In the tax calculation of this calculator, the number of digits after the decimal point is 2 and the 3rd digit after the decimal point is rounded off.
Decimal points are displayed as periods (.), and thousands separators as commas (,).
