Bulk GST calculator
Paste a list of amounts, add or remove Australian GST, then download a clear CSV breakdown.
Paste up to 500 amounts. Commas can separate thousands. Each line is calculated and rounded separately.
| # | Before GST | GST | Including GST |
|---|
Totals add the rounded rows. They can differ from calculating GST once on the combined amount.
One list. A complete GST breakdown.
Enter one dollar amount per line and choose whether the amounts include GST. The table calculates each row separately and adds the rounded results. All entries must be fully taxable at 10% and use the same price basis.
The download includes the line number, amount before GST, GST and inclusive total. No amounts are uploaded. See how to prepare a batch and why rounding can change a total.
