Questions
How do I calculate a total including tax?
Enter the amount before tax and the tax rate you want to use. The large result is the total including tax. The line below it shows the tax amount.
Does this use my local tax rate?
No. You supply the rate. The percentage shortcuts are ordinary percentages, not local tax rates.
Can I enter a custom tax rate?
Yes. The chips are shortcuts only. You can type any tax rate of zero or greater.
How precise are the results?
The large result is a concise reading, normally up to two decimal places. The equation keeps the full meaningful precision from IngoHub’s calculation.
Does IngoHub store the numbers I enter?
No. All calculations are performed instantly in your browser. We do not store or transmit the numbers you enter.
