The shop · calculator

What is left after the sale actually happens.

Landed cost is not the margin. GST, courier, card fees, returns and the ad that won the customer all come out first. This shows the number you can spend — and the price you actually need.

Inside the tool

Built for a product you actually ship.

The sale, taken apart

What the customer pays, what GST you set aside, what landed cost and fulfillment really leave.

Can you afford the ad?

Organic margin vs paid. The ROAS that breaks even. Profit at half, full and 1.5× your CAC.

The price you should be on

Reverse-calculate the RRP for a target margin — instead of hoping 2× cost is enough.

Wholesale, honestly

What a 2× retailer markup does to your number, and the wholesale price that still works.

Who it is for

If you sell a physical product online.

Skincare, apparel, homeware, food, jewellery. NZ GST is on by default. Change the rate if you sell elsewhere. Numbers stay in your browser. Print or copy a summary when you need it in a meeting.

There is a sister tool for service businesses — hourly, sessions and retainers.
