How to use GST Calculator
- Select Add GST for exclusive amounts or Remove GST for inclusive amounts.
- Enter each amount and your independently verified GST rate. Select intra-state or inter-state treatment; add up to 20 lines if needed.
- Inspect base, GST and total amounts. Each line rounds half-up to paise; odd split paise is allocated to CGST.
- Copy or export the estimate. Verify applicability and statutory rounding before using any figures; exports are not tax invoices.
A practical example
₹1,000 exclusive at 18% gives ₹180 GST and ₹1,180 total.
How it works
Exact BigInt scaled-decimal arithmetic. Exclusive GST rounded half-up to paise; inclusive base rounded half-up, GST is total minus base. Odd split paise goes to CGST; SGST is the remainder. Worksheet totals sum rounded lines.
Limits and assumptions
Arithmetic estimator, not a tax invoice or legal advice. Up to 20 lines; each amount INR 0-10 billion with two decimal places; rates 0-100% with four decimals. User verifies applicable rates and supply classification. Cess, UTGST, exemptions, reverse charge, registration, input-tax credit and statutory rounding are excluded.
Frequently asked questions
What does GST Calculator help with?
A GST calculator adds tax to a taxable amount or extracts tax from a tax-inclusive total. Mayexa supports both directions and mixed-rate worksheets. You choose the rate and supply assumptions; the arithmetic does not determine the legally applicable classification, exemption or place of supply.
What should I check before relying on the result?
Review rounding and any CGST/SGST or IGST treatment against the actual transaction. A calculation report is not a tax invoice, filing service or professional tax determination. Verify current rates and invoice requirements from official sources. Amounts are handled locally, and the worksheet does not transmit your sales or purchase details for calculation.
Do I need a Mayexa account?
No Mayexa account is required. Review the workspace's processing labels and limits before entering data.
Does this calculator determine my applicable GST rate?
No. Example shortcuts are arithmetic conveniences, not a current tax-rate table. Verify the applicable rate, classification and notifications through official sources or a qualified adviser.
How are rounding differences handled?
Each line rounds half-up to the nearest paise. Inclusive mode rounds the base and derives GST as the remainder. Intra-state splits allocate an odd tax paise to CGST and the remainder to SGST. Worksheet totals sum rounded lines; statutory rounding may differ.
Are my figures stored or sent to a server?
No. Calculations remain in this browser session, with no saved drafts or input analytics. Copy and text/CSV download occur only when requested.
