✨ Pro Tips for Best Results
- Double Check Slabs: In countries like India, GST rates change frequently. Always verify the current slab (5%, 12%, 18%, 28%) for your specific HSN code.
- Input Tax Credit (ITC): Businesses can often claim back the GST paid on purchases. Use our "Remove Tax" mode to find the exact credit amount you can claim.
- Service Tax vs Product GST: Most services are taxed at 18%, while products can vary. Use the "Common Presets" for quick calculations.
GST Inclusive vs. Exclusive: What's the catch?
Exclusive Pricing is common in B2B (Business-to-Business) transactions where the base price is quoted, and tax is added at the end. Inclusive Pricing is standard in B2C (Business-to-Consumer) retail, where the sticker price already includes all taxes. When comparing international prices, always check if tax is included, as some regions (like the USA) add sales tax only at the checkout counter.
How GST and VAT are calculated
Goods and Services Tax (GST), Value Added Tax (VAT), and Sales Tax are consumption taxes applied to the sale of goods and services. This calculator handles two directions: adding tax to a pre-tax price (exclusive), or extracting the tax component from a tax-inclusive price.
Tax-exclusive (adding tax): Tax amount = Price × (Rate ÷ 100). Final price = Price + Tax.
Tax-inclusive (extracting tax): Tax amount = Price − (Price ÷ (1 + Rate ÷ 100)). Pre-tax price = Price ÷ (1 + Rate ÷ 100).
Standard rates vary by country: India 18% (standard GST), Australia 10%, UK 20%, most EU countries 20–25%, Scandinavia 25%, USA has no federal sales tax (varies 0–10% by state). The calculator includes presets for 19 countries. Always verify the applicable rate for your specific goods or service category — many countries apply reduced rates to essentials like food, medicine, and children's clothing.
