How to use this tool
Enter a price and your applicable tax rate. Choose Add tax or Tax already included. For example, $100 at 8.25% tax totals $108.25.
Good to know
Enter the tax rate yourself; this tool does not look up local tax rules. Supports prices up to $1 billion and rates from 0–100%, with up to two decimal places. Tax is rounded to cents, with half cents upward. Exemptions, compound taxes and jurisdiction-specific rounding are not modeled.
