🧾 GST Calculator
Add or remove GST • Split into CGST/SGST or IGST
If you’ve ever looked at a bill and wondered, “Wait, how much of this is actually GST and how much is the real price?” you’re not alone. Goods and Services Tax (GST) can feel like a puzzle — percentages slapped onto prices, different slabs for different products, and sometimes even confusion between inclusive and exclusive GST. For an everyday buyer or even a small business owner, calculating GST by hand is not just boring, it’s a headache.
That’s exactly why a GST Calculator exists — to save you from doing the mental math. Instead of struggling with formulas, you just enter the original amount and select the right GST rate (5%, 12%, 18%, or 28%). Within seconds, you know the GST amount and the final price you need to pay. If you’re a shopkeeper or freelancer, you can even reverse-calculate — meaning, if the bill already includes GST, the calculator will tell you the base price and the tax portion separately.
This tool is super handy for small businesses preparing invoices, for online sellers calculating margins, or even for regular people just trying to double-check a restaurant bill. No need to worry about under-charging customers or over-paying at the counter.
In short, the GST Calculator takes away the stress of numbers and gives you instant clarity. Whether you’re a buyer, seller, or student learning about taxation, it’s a quick way to make sure you’re always on top of what GST really means for your money.
GST Calculator – FAQs
1) How do I remove GST from a tax-inclusive price?
Choose Remove GST (Total → Base), enter the invoice total and rate. The tool backs out the base using: Base = Total ÷ (1 + rate).
2) When do I use CGST/SGST vs IGST?
**Intra-state** supplies split GST into CGST + SGST (half each). **Inter-state** supplies use IGST (full rate as one tax).
3) Can I set a custom GST rate?
Yes—pick Custom and enter any percentage. Useful for special rates or cess-inclusive scenarios.
4) Does the calculator handle quantities or multiple items?
This light version calculates a single amount. For itemized invoices, multiply item values or ask us for an itemized mode.
5) Are cess or exemptions included?
No—this tool applies only the GST rate you choose. If cess applies, add it separately as per your invoice rules.
