What do you know?

Pick any two. The calculator works out the other two.

What one unit costs you to buy or make, with packing. Leave out GST you claim back as input tax credit.

Before GST: the amount you keep before costs.

Your selling prices are

An MRP on packaged goods already includes all taxes (Legal Metrology rules), so if you sell at MRP, choose "Including GST".

GST rate

The main GST rates since 22 September 2025 are 5% and 18%, with 40% for a short list of goods; some goods are nil-rated. Not registered for GST? Choose 0%: you do not charge GST, and enter costs as you paid them, since you cannot claim the GST on them back.

Several products at once

For each product, type the cost and the selling price (before GST, as chosen above), a target margin, or both. Leave the GST box empty to use the rate above. Up to 50 products.

Import a CSV file or paste a table

Columns: product, cost, selling price, target margin %, GST % (a heading row is optional). Importing replaces the rows above.
