Free Shopify calculators for merchants
Four calculators for the money decisions behind a Shopify store. They run in your browser, on your own numbers.
The calculators
Break-even ROAS calculator
What an order leaves after tax, goods, shipping, fees and returns, and the ROAS ads need before they make money.
Discount break-even calculator
How many more orders a discount has to bring in to earn what full price did.
Bundle pricing calculator
Whether a bundle earns more than single items, and the share of its buyers who must be upgraders.
Project payback calculator
How many months a conversion lift takes to repay a Shopify project, and the lift you would need.
IN SHORT
- Each calculator answers one money question a Shopify merchant has to settle: what ads need to return, what a discount has to win back, whether a bundle pays, and whether a project repays itself.
- They use only the numbers you enter. None has a built-in margin, conversion or sales-lift benchmark, because there is no honest universal one.
- Tax is handled for stores that sell with tax inside the price, as in the UK and Australia, as well as where tax is added at checkout, as in the US.
- Everything runs in your browser. Nothing you type is sent to us or saved.

A calculator gives you the line. The audit shows where your store sits against it.
