A quick guide

Use the number with context

The answer is only useful when you know what it includes and what it leaves out.

How to use it

  1. Enter unit cost using the same period and unit as the other inputs.
  2. Enter target margin using the same period and unit as the other inputs.
  3. Enter expected discount using the same period and unit as the other inputs.
  4. Enter user-supplied tax rate using the same period and unit as the other inputs.

Formula

Pre-tax price = cost ÷ (1 − target margin); customer price = discounted price × (1 + tax rate).

This is a scenario price, not a recommendation of any legally applicable GST or tax rate.

Make it concrete

Worked example

₹600 cost at a 40% target margin, 10% discount and 18% user-supplied tax produces a ₹1,180 customer price.

Questions

Frequently asked

Does this choose the GST rate for my product?

No. Enter a rate only if you already know the assumption you want to model.

Is target margin the same as markup?

No. Target margin is profit as a percentage of selling price; markup is profit as a percentage of cost.
