VAT & Excise Calculator — what it does
Adds or removes VAT, excise duty or service tax on an amount and shows the net, the tax and the gross. Built for pre-GST India and for VAT-based countries, where the same add-and-extract arithmetic keeps coming up on old records and cross-border invoices.
How to use VAT & Excise Calculator
- Choose whether you are adding tax to a net amount or extracting it from a gross figure.
- Enter the amount and the tax rate.
- Read the net, the tax amount and the gross total.
- Use the extraction direction for a receipt that already includes tax.
Worked example: an old excise invoice
A 2016 excise invoice shows a gross of ₹4,72,000 at 12.5%. Extracting tax gives a net of ₹4,19,555.56 and duty of ₹52,444.44 — the figures needed to reconstruct the entry, without the reverse-percentage error that comes from applying the rate to the gross.

- No — it works in any modern browser (Chrome, Edge, Firefox, Safari) with no downloads, accounts or plugins.
- Is this still relevant after GST?
- For current Indian invoices, no — that is the GST calculator. It stays useful for pre-2017 records, for VAT-based jurisdictions, and for any cross-border invoice where the rate is not a GST slab.
- Why does extracting 12.5% not give the tax as 12.5% of the gross?
- The rate applies to the net, not the gross. Tax equals gross multiplied by rate divided by (100 + rate), which is why the same 12.5% produces different numbers depending on which direction you are going.
