❓ Frequently Asked Questions
🤔 How do I calculate combined tax rates?
Simply add all applicable tax rates together. For example, if state tax is 6% and local tax is 2.5%, your combined rate is 8.5%. Enter each rate separately in the calculator for a detailed breakdown.
💡 What is reverse tax calculation?
Reverse tax calculation helps you find the original price before tax when you only know the final price. This is useful for expense tracking, reimbursements, or understanding the true cost of items.
📊 How accurate are the preset tax rates?
Preset rates are approximate and may not include all local taxes. Always verify current rates with your local tax authority, as rates can change and may include special district taxes.
🛍️ What is tax-inclusive pricing?
Tax-inclusive pricing means the displayed price already includes all taxes. This is common in many countries and helps customers know exactly what they'll pay. The calculator helps determine the base price needed to achieve your desired selling price.
📦 How does bulk calculation help businesses?
Bulk calculation saves time by processing multiple items at once. It's perfect for invoicing, inventory management, and calculating totals for shopping carts with different quantities and prices.
💻 Can I save my calculations?
Yes! Use the export options to save your calculations as CSV files for spreadsheets, PDF for records, or copy to clipboard for quick sharing. This helps with bookkeeping and expense tracking.
