Sales Tax / VAT Calculator — Add, Remove & Receipt Totals

Shopping with tax added at the till, or staring at a VAT-included price wondering what the tax was? This free calculator works both directions: add mode turns a net price plus rate into tax and gross for shoppers, while remove mode pulls a gross price apart into net plus the isolated tax component — the VAT-refund view reclaim-registered buyers need.

Enter one amount and one rate for instant answers, or build a multi-item receipt with per-item rates (up to 20 lines) for net, tax and gross totals. Every calculation runs locally in your browser with no sign-up, and any scenario can be shared with a link.

The add/remove formulas

tax=net×rate\text{tax} = \text{net} \times \text{rate}
gross=net+tax\text{gross} = \text{net} + \text{tax}
net=gross1+rate\text{net} = \frac{\text{gross}}{1 + \text{rate}}

Adding multiplies the net by the rate; removing divides the gross by one plus the rate — never subtract a percentage directly, that understates the net. Rates are entered as percent and converted to decimals internally.

Rate as a decimal: 8.875% → 0.08875.

How it works

  1. Pick add (net → gross) for shopping math or remove (gross → net) to isolate tax from a tax-included price.
  2. Enter the amount — net in add mode, gross in remove mode.
  3. Enter one tax rate in percent; it applies to the amount and every receipt line you add.
  4. Optionally add receipt lines with per-item nets and rates for itemised tax, gross and totals.
  5. Read net, tax and gross plus line-by-line and totalled receipt figures.

VAT refunds: isolate, then reclaim

Remove mode exists for VAT-registered buyers: it pulls the tax component out of a tax-included price so you know exactly what to reclaim. Reclaim rules vary by jurisdiction — check your local tax authority before filing.

What v1 leaves out

No jurisdiction rate tables, no live rate feeds, no receipt scanning — enter the rate from your receipt or local authority. Follow-ups add tables and feeds; currency conversion belongs to the currency tool.

Frequently asked questions

Add vs remove — which do I need?

Add when the price excludes tax (US shelf prices): net plus rate gives gross. Remove when the price includes tax (EU/UK VAT prices): it recovers the original net and the tax slice.

Where do I find my rate?

On the receipt line, the store's posted notice, or your local tax authority's tables. Enter it as percent — 8.875, not 0.08875.

How do VAT refunds work here?

Run remove mode on the VAT-included price to isolate the tax component, then reclaim it under your jurisdiction's rules. This tool computes the figure; it does not file anything.

How do receipt lines total?

Each line computes tax and gross from its own net and rate at full precision; totals sum the unrounded slices once, so the receipt always reconciles to the cent.

How accurate is this calculator?

Exact to the cent against the stated formulas. Real receipts round per line or per receipt depending on jurisdiction — penny differences there come from rounding policy, not the math.
