FAQs
1. What is a GST Calculator and how does it work?
A GST Calculator is a free online tool that instantly computes the Goods and Services Tax (GST) amount on a product or service. It works by applying the standard formula: GST Amount = (Original Cost × GST Rate) / 100. You just need to enter the original amount and select the applicable GST rate (e.g., 5%, 12%, 18%, 28%) to get the net price including or excluding GST.
2: How can I calculate Reverse GST or find the pre-GST amount?
Our Reverse GST Calculator is perfect for this. If you have the final price that already includes GST and need to find the original cost or the tax amount, simply select the “Reverse Calculation” mode. Enter the GST-inclusive amount and the rate, and the calculator will instantly show you the base price and the separate GST amount. This is essential for accounting and understanding your actual costs.
3: What are the different GST rates in India, and how do I apply them?
The common GST slabs in India are 0%, 5%, 12%, 18%, and 28%. Our calculator supports all these rates. For most intra-state transactions, the total GST is split into CGST (Central GST) and SGST (State GST), each being half of the total rate. Our tool automatically performs this CGST and SGST breakdown, providing a clear, compliant calculation for your invoices.
4: Can I use this calculator for specific purchases like gold, cars, or flats?
Yes, our calculator is versatile for all goods and services. For gold, apply the 3% rate. For cars and bikes, rates vary (e.g., 18% for small petrol cars, 28% + cess for SUVs). For flat purchases, under-construction properties attract GST (1% for affordable, 5% for others without ITC). Simply input the base price and select the correct rate for an accurate liability calculation.
5: Is this GST calculator suitable for countries like Australia, Canada, and New Zealand?
While our calculator is optimized for India’s GST structure, it can be used for basic calculations in other countries. For Australia (GST 10%), New Zealand (GST 15%), and Canada (GST 5% + Provincial Sales Tax/PST or HST), you can manually input the applicable total tax rate. However, for complex Canadian HST/PST calculations, we recommend a country-specific tool.
6: How do I calculate GST inclusive and exclusive amounts?
To calculate GST Inclusive Price:Â Enter the base price, and the calculator adds the GST to show the final price.
To calculate GST Exclusive Price (Reverse GST):Â Enter the final price that includes GST, and the calculator will subtract the tax to show the original base price and the GST amount separately. Our tool handles both scenarios effortlessly.
7. Can I calculate GST on loans, EMIs, or credit card payments?
GST applies to the processing fees and interest components of financial services. For a loan EMI or credit card EMI, GST is levied on the processing fee charged by the bank and on the interest amount. While our standard calculator gives you the base tax amount, you would need to apply the 18% GST separately to these fee components as per your bank’s breakdown.
8: How do I calculate GST late fees and interest on delayed payments?
Calculating late fees and interest is complex as it depends on the delay duration and tax liability. Our GST late fee calculator helps estimate this. Interest is typically 18% per annum on the outstanding tax amount. For a precise calculation tailored to your specific delay and tax dues, it’s best to consult a tax professional or use the official GST portal.
9: Is the calculator available as a mobile app or for download?
Our GST calculator is a web-based tool, making it accessible from any device with a browser—no app download required. It is mobile-friendly and works like an app on your phone. We do not offer an APK download or a modded version to ensure security and accuracy for all users.
10: How accurate is the free online GST calculator compared to tools from Cleartax or Zoho?
Our free GST calculator is highly accurate and uses the same fundamental principles as tools from Cleartax, Zoho, or Taxadda. The core calculation of GST is standardized. The main difference often lies in user interface and additional features like invoice generation. Our tool focuses on providing a fast, reliable, and easy-to-use calculation experience for everyone.
