FAQ
Can I get a tax-included price at 10%?
In "Tax included/excluded", set the tax rate to 10 and choose "To tax-incl".
Can I back out the pre-tax price?
Yes. Choose "To tax-excl" to reverse-calculate the tax-excluded price.
Why is the rate of change negative?
When the "after" value is smaller than "before", it shows a negative (decrease) percentage.
Is the calculation done on a server?
No. Everything is computed in your browser and no data is sent.
