Tired of second-guessing your GST calculations?

Whether you’re billing a client, setting product prices, or just double-checking a receipt—GST math shouldn’t slow you down.

That’s why the HR HUB GST Calculator is your new go-to. It’s lightning-fast, zero learning curve, and most importantly—100% accurate.

Let’s walk you through the easiest way to calculate GST online.

How to Calculate GST Using HR HUB's Online Calculator (Step-by-Step)

Whether your price is GST-exclusive or inclusive, HR HUB’s GST tool handles both situations in seconds. Here’s how to use it:

Step 1: Choose GST Mode (Exclusive or Inclusive)

At the top, you’ll see two buttons:

• GST Exclusive (if your amount does NOT include tax) is used when you want to add tax to a base price.
• GST Inclusive (if your amount already includes tax) is used when you want to extract the GST amount from a final price.

Click the one that fits your scenario.

Step 2: Enter the Total Amount (₹)

Type in the base or final amount you’re working with. Example: ₹5000

Step 3: Select the Tax Slab (%)

Move the slider or type in your GST rate. Common slabs are:

• 5%, 12%, 18%, 28%

Additionally, you can enter custom rates, like 15%.

Step 4: View Results Instantly

Once the values are in, the tool will auto-calculate:

• Total GST: The tax amount calculated
• After GST, the base price (if inclusive) or final price (if exclusive)

That's it! No stress, no formulas—just outcomes.

Why You Need a GST Calculator in 2025

GST is now a major factor in pricing, invoicing, and compliance; it is no longer merely a backend tax. With businesses becoming more complex and rates changing, a GST calculator is more than just a useful tool—it's essential.
